Andy is an RCVS and European Veterinary Specialist in Small Animal Oncology and Lecturer in Veterinary Oncology at the RVC, working in the Queen Mother Hospital for Animals. Andy supervises and trains oncology residents, teaches undergraduate students, sees small animal oncology patients, and undertakes research.

Andy graduated from The University of Nottingham and initially spent two years in small animal general practice. He subsequently undertook a small animal rotating internship and medical oncology residency at the Royal Veterinary College, also completing a postgraduate diploma and master's degree. He gained his Diploma in Small Animal Oncology from the European College of Veterinary Internal Medicine (ECVIM) and is now a Lecturer in Veterinary Oncology. 

Clinically, Andy has a particular interest in canine mast cell tumours and leveraging sentinel lymph mapping to improve the accuracy of cancer staging. His research interests focus on the diagnostic, therapeutic and prognostic role of the oncobiome, particularly the intestinal microbiome. He is also interested in novel diagnostic and therapeutic strategies in veterinary cancer patients, particularly those where there is translational relevance.

Andy leads the RVC's Comparative Physiology and Clinical Science (CPCS) Oncology Research Group, and is also a member of the RVC's clinical research ethical review board (CRERB). He holds a Home Office personal license (PIL) under the Animals (Scientific Procedures) Act. He is Associate Editor of Veterinary Oncology. Andy is a trustee of the Zeus and PJ Charitable Foundation, a charity aimed at funding lifesaving cancer treatment for dogs whose owners are not able to do so. 

Andy contributes to the wider veterinary profession by providing oncology CPD, and is a regular invited speaker at numerous national and international conferences.
