Professor Roger Woledge
RCW obtained his BSc in Physiology in 1959 at University College London followed by research training with A.V.Hill 1959-62. He remained in UCL Physiology until his retirement in 2003, being Head of Dept (1988-1994) and Director of Institute of Human Performance in Stanmore (1994-2013). Since retirement he continued research work at Imperial College (until 2010), at Kings College London, at Queen Mary University London and more recently at the RVC (until 2015).
RCW's research concerns muscle contraction and in particular in-vitro measurement of the energetic cost of muscular activity. Since 1973 this research has been in collaboration with Prof N.A.Curtin (qv). They have investigated the muscle energetics of a number of different vertebrates (Frog, Tortoise, Lizard, Eel, Dogfish, Mouse) and sought theoretical explanations using crossbridge theories. Since 1985 RCW has been collaborating with Dr S.A. Bruce on investigations of human muscle strength and the weakness caused by age and hormonal status.

Dr Vivian Allen
Viv earned his BA in Archaeology and Geology in 2004 from the University of Bristol, and stayed there another year to study for an MSc in Palaeobiology, supervised by Prof. Michael Benton, where he did his thesis project on dinosaur biomechanics.
Interest in biomechanics led Viv to study for a PhD, supervised by John Hutchinson at the RVC's Structure and Motion Laboratory, in the functional evolution of the hindlimb in theropod dinosaurs.
Subsequently, Viv accepted a postdoc position at the Friedrich-Schiller University, Jena (Germany), studying the mechanics of sprawling locomotion in lizards and crocodiles. He returned to the UK to a postdoc position back at the RVC's Structure and Motion Laboratory, working on the biomechanics of sesamoid bones.
Viv's research project aimed to understand the biomechanics underlying sesamoid bone formation, using the patella of mammals, lizards and birds as a model. The goal was to use a combination of muscle-tendon force simulation and finite element modelling to predict loads and load patterns present in the patella tendon, both with and without a mechanically discrete patella or similar structure, to determine if sesamoid formation can be associated with a particular stress concentration or regime.

Dr Borja Esteve-Altava
Borja has been awarded a La Caixa Junior Leader Fellowship at Pompeu Fabra University in Spain to work at the Department of Experimental and Health Sciences to carry out a research project on the evolution of craniosynostosis, a pathological condition in newborns with intriguing links with the macroevolution of the vertebrate head.
Borja is an evolutionary biologist with a track record in morphology and mathematical biology. His research focuses on developing analytical tools to model animal anatomy, characterizing evolutionary patterns, and studying the relationship between evolution and craniofacial anomalies with implications for human health.
2015 – Marie Skłodowska-Curie Fellowship. Royal Veterinary College, UK.
2013 – PhD in Biodiversity. University of Valencia, Spain.
2012 – Writing-up Fellowship. Konrad Lorenz Institute, Austria.
2008 – Master in Biodiversity and Evolution. University of Valencia, Spain.
2007 – Bachelor in Biology. University of Valencia, Spain.
Borja worked with Prof. John Hutchinson on the evolution of the anatomical structure of pectoral and pelvic appendages during the transition from fins to limbs. They used anatomical network models to quantify anatomical structures and compare them in a phylogenetic context to understand better this key event in vertebrate evolution.

Following her position with the RVC Hannah has returned to clinical practice.
Hannah graduated with Honours from the University of Nottingham in 2012 as a Veterinary Surgeon. Having gone straight into clinical practice, she spent over a year at a hospital practice in South Wales and then moved back to the Midlands to locum at several small animal practices for the six months preceding the start of her position at the RVC.
The remit of Hannah's work has been to understand the anatomical and muscle physiology specialisations for economical locomotion and migration of large African herbivores. She has analysed data collected using innovative GPS tracking collars, aerial filming systems and muscle biopsies, studying parameters such as preferred gait, speed and muscle performance at individual fibre level.
Her fieldwork was conducted on the savannahs of Eastern and Southern Africa: the Serengeti, Botswana, Zimbabwe and South Africa, studying zebra, wildebeest, impala and other large herbivores. This built on pilot studies in the UK, using predominantly domestic dogs and horses to test the tracking and filming equipment to ensure all the kit was working as expected before flying out to field locations.
Although the focus of the project has been on locomotion and physiology, the results will also be of relevance to behavioural ecology, wildlife conservation and habitat management.
Professor Alan Wilson leads a team of researchers in the southern African savannah to identify how speed, manoeuvering and habitat impact the hunting and evasion practices of carnivores and their prey.
Dr Peter Falkingham
Peter is currently working as a Senior Lecturer in the School of Natural Sciences and Psychology at Liverpool John Moores University.
Dr Falkingham holds a BSc (hons) in Biology and Geology (2003) and a MSc in Computer Science (2004), both from the University of Bristol.
His PhD was carried out at the University of Manchester on Computer Simulation of Dinosaur Tracks, aiding in development of the finite element analysis software ParaFEM to simulate the indentation of dinosaur feet into cohesive substrates.
In 2012 Dr Falkingham was awarded a Marie Curie International Outgoing Research Fellowship, in order to study theropod locomotor evolution, as expressed in fossil tracks. This three year fellowship involved two years at Brown University, USA, before returning to RVC in 2014.
Peter subsequently took up his current post as a Senior Lecturer at Liverpool John Moores University in the School of Natural Sciences and Psychology.
Peter's primary research focus is on dinosaur tracks, specifically how the foot and sediment interact, and how we can subsequently reverse-engineer their formation in order to constrain and understand the limb motion of these extinct animals.
While a skeleton is a record of an animal's anatomy, a track is formed in vivo, recording the animal during life. As such, fossil tracks and trackways provide additional, complimentary data to the body fossil record. By understanding the motion of substrate around a dynamically moving foot, it is possible to use tracks to constrain possible motions of the distal (and therefore proximal) limb. Peter's work incorporates digitisation of fossil tracks and computer simulation. In addition, his work incorporates data from extant taxa using XROMM techniques to study the motion of the foot during locomotion over deep, soft substrates.
In additional to his work on footprints, Peter is also involved in other research areas including dinosaur biomechanics and taxonomy, development of digitsation techniques and applications, cambrian echinoderm hydrodynamics, and materials science, collaborating with scientists from the UK, USA, across Europe, Australia, and South America.

Dr Shin-ichi Fujiwara
Shin-ichi has been working as an Assistant Professor for The Nagoya University Museum since 2012.
Shin-ichi finished his BSc (Earth Science) from the University of Tokyo supervised by Prof. Tatsuo Oji in 2003 for his research about living posture in extinct crinoid which uniquely occurs from muddy substrate.
He went on to the Department of Earth and Planetary Science, the University of Tokyo, for his MSc and PhD, supervised by Prof. Tatsuo Oji and Dr. Makoto Manabe (National Museum of Nature and Science, Japan). He began to focus on reconstruction of forelimb postures in extinct tetrapods for his graduate research, and finished his MSc thesis on a new reconstruction of manus structure in ceratopsid dinosaurs. Inspired by fuctional morphology, biomechanics, and comparative anatomy, he was devoted to study relationships between skeletal morphologies and the limb postures for his PhD.
After he finished his PhD in 2008, he moved to Dr. Takenori Sasaki's lab, the University Museum, the University of Tokyo (UMUT), as a research cooperator, and kept on studying reconstructions of limb postures in extinct animals. In 2009, Shin-ichi moved to Prof. Hideki Endo's lab (UMUT) as a postdoc research fellow, and started studying the limb postures in inverted and sprawling quadrupeds He also visited Dr. John R. Hutchinson (RVC) for three months funded by Anne Sleep Award, the Linnean Society. In 2010, he was funded by Japan Society for the Promotion of Science at Prof. Hideki Endo. Shin-ichi joined RVC as an academic visitor in May 2010 for the research of sprawling limb posture and related topics with Dr. John R. Hutchinson.
Shin-ichi returned to UMUT (http://www.um.u-tokyo.ac.jp/en/) in May 2011 as a postdoc research fellow.
Shin-ichi's research focuses on relationship between skeletal morphologies and the actual limb postures of the animals based on functional morphology and comparative anatomy. His research aims to reconstruct reliable limb postures in extinct tetrapods (e.g., ceratopsian dinosaurs and desmostylian mammals). He also aims to reveal how the limb posture diversified among the lineages of tetrapods. Shin-ichi's previous/ongoing topics are as follows:
- Reconstruction of living posture on muddy substrate in a fossil crinoid.
- Evolution of manus structure in ceratopsian dinosaurs.
- Relationship between scapular position and strength of rib in quadrupedal tetrapods.
- Relationship between olecranon orientation and elbow joint angle in extant quadrupedal mammals.
- Reconstruction of elbow joint angle in desmostylian mammals and ceratopsian dinosaurs.
- Comparison between shapes of articular surface and calcified epiphysis of limb bones in sauropsids.
- Relationship between skeletal morphology and forelimb posture in inverted (upside down) quadrupeds.
- Relationship between skeletal morphology and sprawling forelimb posture.
Beside his research, Shin-ichi have overseen reconstructions of the motions and postures of extinct animals in computer graphic movies exhibited in National Museum of Nature and Science, Tokyo, Japan, and Gunma Museum of Natural History, Tomioka, Japan. He have also overseen reconstructions of many scientific illustrations and models in ceratopsian dinosaurs.

Dr Andrew King
Andrew left the RVC to join Swansea University’s College of Science in a permanent academic position in September 2012 and is now a Senior Lecturer in Biosciences.
A NERC Research Fellow, Andrew’s work uses a question-oriented approach to address a range of issues in behavioural and evolutionary ecology, especially concerning group-living animals. For more information see Andrew's personal research pages.
Andrew has a PhD in Behavioural Ecology. He is an Honorary Research Fellow at the Department of Zoology, University of Cambridge (Evolutionary Ecology Group), and is a member of the Tsaobis Baboon Project (Zoological Society of London) and the Baboon Research Unit (University of Cape Town). He is also serves as an Editor for Animal Behaviour,and is a Member of The NERC Peer Review College.
At the RVC Andrew was based in the Structure and Motion Laboratory, a Centre of Excellence at the forefront of developing technologies to study animal movement, where he uses a question-oriented approach to examine how costs and benefits shape individual behaviour, so that he can understand how these behaviours relate to the structure and functioning of groups and populations. He uses a variety of group-living fish, bird, and mammal systems to answer these important research questions.
Andrew's research is team-oriented, and he collaborates with a variety of individuals and institutions to find innovative ways to tackle his research questions, blending theoretical modelling and field observations and experiments. He has spent nearly three years in Southern Africa, studying the behaviour and ecology of baboons in the Namib Desert, and meerkat sociality in the Kalahari Desert. He still gets into the field to study wild populations, but is enjoying answering his questions in his new fish laboratory at the RVC.
Andrew lectures on the 'Animal Behaviour and Welfare' and 'Comparitive Animal Locomotion' modules as part of the BSc Bioveterinary Science degree. Andrew guest lectures for Imperial College, London. Andrew supervises two PhD students, Leah Williams (personality and leadership in a social bird) and Diamanto Mamuneas(collective performance in animal groups).

Dr Olga Panagiotopoulou
Olga left the RVC in 2013 to take up a position as Lecturer in Anatomy at the School of Biomedical Sciences, The University of Queensland, Australia.
After completing a MSc degree in human osteology and palaeopathology at the University of Bradford, Olga moved to the University of York to do a PhD funded by Marie Curie-MEST-CT-2005-200601.
This PhD project was supervised by Dr. Samuel Cobb of the Functional Morphology and Evolution Research Unit of the Hull York Medical School (HYMS) and was also conducted in cooperation with the Centre of Medical Engineering and Technology (CMET) of the University of Hull. Using medical imaging techniques, 3D virtual reconstruction and Finite Element Analysis (FEA) Olga tested whether symphyseal morphology reflects an adaptational balance between the spatial requirements of housing the developing anterior dentition and the biomechanical functional maintenance during ontogeny. The validity of the FE models was tested by carrying out experimental strain measurements in the laboratory using laser speckle interferometry and strain gauges analyses.
Being highly qualified in the application of FEA and experimental techniques for the comprehension of the form-function relationship of anatomical structures Olga joined the Structure & Motion Lab in RVC following her PhD to further expand her research expertise in skull/feeding biomechanics with a new repertoire in limb/locomotion biomechanics.
Olga's research is focused on assessing the links between form (morphology), function (mechanics) and development of the terrestrial vertebrate musculoskeletal system during feeding and locomotion.
Why does the vertebrate musculoskeletal system vary so widely--or in other words, what are the functional and developmental consequences of anatomical variation? Evolutionary history surely has played a huge role in shaping musculoskeletal form, but how do developmental changes in musculoskeletal mechanics and scaling factors during ontogeny constrain and/or direct the morphology and composition of musculoskeletal design?
Olga's research in feeding mechanics seeks to determine the function of the primate and mammalian chewing apparatus as it relates to dietary ecology, dental morphology and development in adulthood and during ontogeny. Using in vivo experimental techniques, computer simulations and mathematical models she studies how the modulation of muscle activity affects the motion of the jaw and how this interaction affects the morphology of the mandible and the dental tissues. She also explores the effect of developmental factors, such as the crypts of the developing dentition on mandibular form.
Her research on feeding mechanics has generated ongoing collaborations with Dr. Ross (University of Chicago, USA), Dr. Cobb (Hull York Medical School, UK), Prof. Dechow (Baylor College of Dentistry, Dallas, USA), Dr. Taylor (Duke University, USA), Dr. Iriarte-Diaz (University of Chicago, USA).
Olga's locomotor interests seek to study the basic principles of foot form, function and evolution and also determine how regional loads on foot structures (bones, joints, pads, ligaments and tendons) relate to the occurence of pathologies.
The most common cause of morbidity and death in animals in captivity and domesticity is foot disease (pathologies). Foot pathologies encountered clinically are similar across species, including humans, and encompass degenrative (e.g. osteoarthritis, tendonitis, laminitis), infectious (e.g. foot abscesses) and traumatic (e.g. fractures) disorders. Foot disease is often progressive, painful and treatment unrewarding in many cases leading to disabled and euthanised animals. Prevention is hence the key in ensuring the welfare of those animals, and knowledge about the main factors contributing to foot disease an essential prerequisite. The cause of these pathologies is multifactorial. The biomechanical foot-ground interaction is a critical contributor, particularly the high frequency vibrations when the foot hits the ground during locomotion, as well as large forces (hence stresses and pressures) imposed later in the step which can exacerbate pathology even if not the primary cause.
Olga's research on locomotor mechanics has been in collaboration with Prof. Hutchinson (The Royal Veterinary College) and has generated ongoing collaborations with Dr. Pataky (Shinshu University, Japan).

In August 2005, she was employed as a full time Lecturer in Anatomy and Biomechanics.
Rachel is particularly interested in the relationships between functional anatomy, whole limb design and locomotion. She is currently investigating functional locomotor anatomy in animals designed for speed, endurance and adaptability (horse, greyhound, ostrich, hare, camel, primate, cheetah, lion, tiger, okapi). Her other work includes research into the evolution of bipedalism through the study of living primates and studies of the biomechanics and energetics of human bilateral amputee gait.
Rachel is a dedicated educator and has taught anatomy, biomechanics and evolution across many RVC undergraduate and postgraduate courses. She has also been Course Director of the Gateway Programme which provides students from low income families with the opportunity to attend vet school.
Rachel returned to the RVC for a time to work at the CETL LIVE Centre conducting research into veterinary education.

Dr Stephanie Pierce
Stephanie is currently employed as an Assistant Professor of Organismic and Evolutionary Biology at the University of Harvard.
Stephanie graduated with an Honours in Palaeontology BSc degree from the University of Alberta, Canada. Directly following this, she pursued an MSc degree by research in Systematics and Evolution at the University of Alberta studying the anatomy and evolutionary relationships of extinct marine lizards. Her love of vertebrate evolution brought her to the University of Bristol, UK, where she embarked on a PhD degree which focused on assessing the interplay between skull shape variation and biomechanical performance in extant and extinct crocodiles. Stephanie subsequently began working as a Temporary Lecturer at the RVC in Evolutionary Biomechanics, examining the locomotion potential of early tetrapods. Stephanie is now working as an Assistant Professor Organismic and Evolutionary Biology at the University of Harvard and is a Curator of Vertibrate Paleontology in the Museum of Comparative Zoology.
Stephanie's scholarly interests are focused on assessing the link between form and function of the vertebrate skeletal system – especially with respect to muscle/skeletal interactions during feeding and locomotor behaviours in modern and extinct animals.
Stephanie has primarily been working on unravelling the locomotion potential of the earliest limbed vertebrates in collaboration with Prof Jenny Clack in the Museum of Zoology, Cambridge and Prof John Hutchinson at the Royal Veterinary College.

Dr Laura Porro
Laura was employed as a postdoctoral researcher in the Structure and Motion Laboratory working with Dr. Chris Richards on an ERC-funded project looking at the evolution of locomotion in amphibians that incorporates data from in vivo and in vitro experiments, medical imaging, computer modelling and paleo-robotics.
Laura attended the University of Illinois at Chicago, graduating with degrees in Biological Scie nces and Earth and Environmental Sciences in 2004. She completed her PhD in Palaeobiology (funded by a Gates Cambridge Scholarship) in the Department of Earth Sciences at the University of Cambridge in 2009, investigating anatomy and cranial biomechanics in heterodontosaurid dinosaurs. Laura was a postdoctoral scholar in the Department of Organismal Biology at the University of Chicago, using in vivo experimental methods and computer modeling to understand skull mechanics in crocodilians, lizards and primates. From 2012 - 2014, Laura was a Marie Curie Research Fellow based in the School of Earth Sciences at the University of Bristol and the Zoology Department at the University of Cambridge, exploring changes in morphology and function in the early tetrapod lower jaw across the water-land transition.
Frogs possess a unique skeleton thought to reflect adaptation to jumping. Yet living frogs are capable of running, walking, swimming, climbing and burrowing as well as jumping. How can such multi-functionality be acheived without compromising individual functions? What was the ancestral locomotor style for frogs and what drove the evolution of their unique body plan? Using a combination of medical imaging, computer modelling techniques (musculoskeletal, inverse kinematic, and finite element analysies) and experimental methods (high-speed video, XROMM, EMG, muscle physiology), my project investigates the correlation between musculoskeletal anatomy and function of the hind limbs in living AND fossil frogs to understand why these adaptations arose and how frogs acheived multi-functionality.
In addition to carrying out research at the RVC, Laura continued to work on fossil reptiles, early tetrapods and fish with collaborators across the UK, Europe, the USA and South America.

Dr James Wakeling
James works as an Associate Professor for Simon Fraser University, Canada.
James studied for his PhD in insect aerodynamics at Cambridge and subsequently did postdoc research at St. Andrews into fish hydrodynamics and muscle physiology, and at Calgary into muscle recruitment during running. James started work at the RVC in 2004, where his research topics in locomotor biomechanics covered a range of mammalian species.
James left the RVC at the end of 2007 and to take up a post in Vancouver, Canada working in the School of Kinesiology at the Simon Fraser University.
The role of different motor units to muscle function is poorly understood for locomotor tasks, and current research topics include establishing the link between different types of motor units and different movement tasks. One muscle task is the damping of soft-tissue vibrations which may be achieved by the preferential recruitment of a class of motor units. Being able to modify vibration input into a body through the altered design of shoes and equipment may thus play a role in athletic training and performance as well as in rehabilitation after injury.
The body interacts with external forces during movement, and these influence the muscle activity required for different tasks. For instance, using orthotic interventions can alter muscle activity patterns. It is thus possible that such interventions could be designed to cause specific changes in the muscle activity patterns with potential benefits to the relief of musculo-skeletal conditions such as patellofemoral pain and osteoarthritis.
Lameness in horses can be alleviated by a number of methods. The scientific evidence supporting the efficacy of some treatments is insubstantial. We are currently developing objective and quantitative measures for the assessment of lameness which will be used to assess different treatment regimes.

Dr Alexis Wiktorowicz Conroy
Alexis graduated with a biology degree from the University of California Santa Cruz (UCSC) in 2002. She pursued her interests in marine biology and comparative physiology, working with Terrie M Williams on seasonal differences in bottlenose dolphin blubber characteristics.
Inspired by the interaction between physiology and ecology, Alexis worked on her PhD with Malcolm S Gordon at University of California Los Angeles (UCLA). Here she studied the biomechanics and kinematics of swimming pufferfishes, which entailed examining locomotion patterns and measuring recoil movements and drag forces. Her collaborators included Dean Lauritzen, Mori Gharib (Caltech),Jay Hove (University of Cincinnati), Hao Liu (Chiba University, Japan) and John Dabiri (Caltech).
Alexis joined the Structure & Motion Lab in January 2008 to explore the field of terrestrial biomechanics. At present Alexis is working on the influence of locomotor behaviour on appendicular skeleton organisation at the macro and micro-structural levels.

Dr Thomas Witte
Tom worked at the RVC as an Equine Surgeon and Senior Lecturer. Recognised as an RCVS, American and European Specialist, his clinical interests include head and neck surgery and minimally invasive surgery. His research focuses on the biomechanics and control of the locomotor system and upper respiratory tract.
Tom qualified from The Royal Veterinary College in 2000. After a period in first opinion equine and farm animal practice (Garston Veterinary Group, Frome, Somerset) Tom returned to the Structure and Motion Lab at the Royal Veterinary College to complete a Horserace Betting Levy Board funded PhD in Equine Biomechanics, with a focus on the locomotor capacity of performance horses. A subsequent move to the USA enabled him to undertake an Internship in Equine Surgery at the Hagyard Equine Medical Institute in Kentucky and a Residency in Large Animal Surgery at the Cornell University Hospital for Animals in New York State.
Tom developed an interest in the biomechanics of the equine athlete whilst an undergraduate in Veterinary Medicine at the Royal Veterinary College (RVC). During this time, he undertook research into the effects of shoe material on the biomechanics of foot-off in the horse.
Subsequently, his Horserace Betting Levy Board-funded PhD focused on the constraints to high-speed locomotion in the racehorse, and involved the development and validation of a suite of tools for determining limb load, trunk motion and animal velocity. These techniques enable the locomotion of a variety of species, including the horse, ostrich and camel, to be measured under ‘natural’ field conditions and form the basis of ongoing work at the Structure and Motion Lab. Key questions regarding the limitations to high-speed locomotion in the equine athlete, and how these relate to injury risk, remain unanswered, and these were the main focus of Tom's research at the RVC.
Upper respiratory tract diseases can result in critical performance limitations across all equine athletic disciplines. During his residency, Tom's research work at the Cornell University Equine Performance Testing Clinic focused on the biomechanics of surgical techniques for the treatment of dynamic upper respiratory tract obstruction.
Tom's clinical interests lie in the area of general (soft tissue) surgery, including Equine, Farm Animal and Camelid species. In particular, through working at the Cornell University Equine Performance Testing Clinic he has developed a keen interest in upper respiratory tract surgery. A current focus is on refinement of the treatment of sinunasal disorders, including new techniques for dental extraction in the standing patient, and minimally invasive approaches to the treatment of diseases of the paranasal sinuses of the horse.
