Monica is a Senior Lecturer in Locomotor Biomechanics. Her research team investigate the integrative physiology and biomechanics of how animals move through complex terrain.

Monica earned an HBSc in Biology with a Chemistry minor at University of Utah, where she was inspired to pursue an academic career through her  research on human locomotor-ventilatory integration with Dennis Bramble and David Carrier. Monica then spent a year at a research technician at the University of Utah in the lab of Franz Goller, investigating motor control of singing in zebra finches. These experiences initiated a long-standing fascination with the interplay of mechanics and neural control.

Monica went on to Harvard University, where she completed MA and PhD degrees in Organismic and Evolutionary Biology. Her graduate studies were supported by a prestigious Predoctoral Fellowship award from the Howard Hughes Medical Institute, and supervised by Andrew Biewener at the Concord Field Station of Harvard University (CFS Website).

After completing her PhD in 2006, Monica spent 1.5 years as a Research Fellow with Dan Ferris in the Human Neuromechanics Lab at University of Michigan, in collaboration with Auke Ijspeert in the Biologically Inspired Robotics Group at the Swiss Federal Institute of Technology in Lausanne. Her postdoctoral fellowship was awarded by the U.S. National Science Foundation.

Monica joined the RVC in January 2008 as a faculty member of the Structure and Motion Lab, and was promoted to Senior Lecturer in 2011.

Monica is a Fellow in The Higher Education Academy, and a member of several professional societies including the Society for Integrative and Comparative Biology, Society for Experimental Biology and the American Physiological Society.  She serves as an Associate Editor for the journal Royal Society Open Science and on the Editorial Board for Physiological and Biochemical Zoology. She has given 16 invited international talks in the past 5 years. 

Locomotion is a key behaviour for most animals, including humans. To survive and reproduce, animals must move through complex environments to obtain food, escape predators, and find mates. Animal locomotion often involves impressive athletic feats such as long distance migration, high speeds, and rapid manoeuvring. Animals accomplish a wide range of behaviours with a single physiological system and yet still often out-perform human-engineered machines.

Dr Daley an integrative physiologist, broadly interested in the sensory, mechanical, neuromuscular and energetic factors that influence animal locomotion. Daley’s research team investigate how animals achieve robustly stable, economic and agile locomotion in complex terrain. This research is at the interface of muscle physiology, energetics, neural control, mechanics and bio-inspired robotics.

We use an integrative approach that combines a range of experimental techniques in biomechanics and physiology with computer simulations and collaborative bio-inspired design and control of legged robots. We work with engineers to translate biological principles into technological applications.

We often use ground birds as a model system because birds are diverse bipedal athletes that span a large size range from tiny 35 gram painted quail to ostriches over 100 kg. Yet, ground birds use striding bipedal gaits that are mechanically similar to human walking and running. By studying ground birds, we can reveal how muscle-tendon architecture, leg morphology, body size and terrain environment influence bipedal locomotion.

This research provides insight into natural animal behaviour, evolution of leg morphology, and injury mechanisms in domestic and wild species. Such insights can inform health and welfare issues including mobility throughout the lifespan, gait pathology, fall prevention and rehabilitation.

Alongside research in comparative animal locomotion, Daley maintains interests in human locomotion research, including biomechanics, energetics, locomotor-ventilatory interactions and rehabilitation approaches informed by neuromechanical principles.
