Rebecca is curently undertaking a two year Clinical Scientist Fellowship at the RVC. She spends the majority of her time performing research, with the remainder split between lecturing/teaching and supervising clinical training scholars and undergraduate students in the Queen Mother Hospital for Animals.

Rebecca graduated from the University of Cambridge in 2007 and worked for three years in small animal practice, during which time she undertook a certificate in feline medicine. She subsequently completed a PhD focused on calcium-phosphate homeostasis in feline chronic kidney disease at the RVC, followed by a rotating small animal internship, and a residency in small animal internal medicine. Rebecca gained her ACVIM diploma in 2018. She is interested in all aspects of canine and feline internal medicine, although is particularly interested in nephrology and endocrinology.

Rebecca is currently involved in research into the following conditions:

  • calcium oxalate nephrolithiasis in cats
  • feline chronic kidney disease and management of CKD-mineral and bone disorder
  • canine hyperadrenocorticism diagnosis and improving management of this condition
  • anaesthesia protocols for dogs with diabetes mellitus
  • factors associated with diabetes mellitus in Burmese cats

Rebecca has various teaching roles including undergraduate clinical rotational teaching and Senior Clinical Training Scholar supervision. She is involved in didactic teaching of the 3rd and 4th year BVetMed students in internal medicine related subjects, and lecturing the BVetMed students in feline infectious diseases. Rebecca is also involved in supervising the urinary part of the Veterinary Nurse graduate diploma.

Rebecca enjoys all internal medicine cases, but is particularly interested in seeing the follwoing:

  • Cats with kidney stones
  • Cats with hypercalcaemia
  • Cats and dogs with any kidney problems or lower urinary tract disorders
  • Dogs with hyperadrenocorticism
  • Cats and dogs with endocrine disorders

Rebecca oversees the medical management for all cats that are seen for management through the QMHA subcutaneous ureteral bypass (SUB) clinic. She is always happy to discuss cases of feline upper urinary tract stones.
