Dept of Medicine and Epidemiology – School of Veterinary Medicine

Dr. Beaufrère main research area is on lipid disorders and lipid diagnostic tests in birds and reptiles such as studies on atherosclerosis, hepatic lipidosis, and plasma lipid biomarkers. Dr. Beaufrère is also very active in clinical research in companion zoological medicine on a variety of topics and has a special interest in applied biostatistics in zoological medicine.

STAR students will participate in research projects related to sodium fluoride pet-scan of arteries in Amazon parrots: comparison of scanning protocols /CT contrast timing in bearded dragons.

Please email Dr. Beaufrere for more information.

Adrien Dupanloup, DVM, DACVIM (Neurology)

Assistant Professor of Neurology and Neurosurgery

VM: Surgical & Radiological Sciences

(See also: Surgery, Neurobiology/Neurology)

My research centers on neurosurgery, with a focus on advancing diagnostic and therapeutic approaches for intracranial diseases in companion animals. Student interested in clinical research in neurology and neurosurgery can be involved in studies involving perioperative diagnostic tests including MRI, CT, electroencephalography and cerebrospinal fluid analysis among others.

Stanley Marks , BVSc, PhD, Dip. ACVIM (Internal Medicine, Oncology), Dip. ACVN

VM: Medicine & Epidemiology

(See also: GI Physiology/Gastroenterology)

Dr. Marks is a veterinary gastroenterologist and nutritionist who runs the Companion Animal Gastrointestinal Laboratory. His research group have been characterizing enteric bacteria (Clostridial species, Campylobacter jejuni, Salmonella spp.) and protozoa (Giardia, Cryptosporidium, Tritrichomonas foetus) associated with diarrhea in dogs and cats, and evaluating diagnostic tests and therapeutic strategies to eradicate the organisms. Dr. Marks is also actively involved in research involving esophageal motility disorders and gastroesophageal reflux (GER), using high-resolution manometry (HRM), esophageal pH/impedance, videofluoroscopy swallow assessment, and esophagoscopy. His laboratory has multiple ongoing studies evaluating the effects of motility modifiers, acid suppressants, and anti-inflammatories on esophageal motility and GER.

For 2026, all projects are focused on gastroenterology of dogs and cats. Specific projects involve the evaluation of the effects of different acid suppressants (PPIs and H2RAs) on gastric and esophageal pH; the effect of prokinetic drugs and anti-emetics on gastroesophageal reflux during general anesthesia; the assessment of narrow-caliber endoscopes for evaluation of the esophagus and stomach in lightly sedated dogs; and the pharmacokinetics of GI drugs that can be used to treat delayed gastric emptying and esophageal disease. Students will gain experience in HPLC, working with endoscopes, becoming highly skilled at performing physical examinations on dogs and cats; becoming proficient in placing esophageal pH sensors and interpreting data collected from the device and similar interventional diagnostic tools. Students will gain proficiency in performing a comprehensive literature search, writing a grant, learning how to use reference managers, become proficient in data reference managers such as REDCap, analysing data, and working closely with a statistician to evaluate datasets. Lastly, the student will also become more proficient at writing a peer-reviewed manuscript.

Jessica Morgan, DVM, PhD, DACVSMR

VM: Medicine & Epidemiology, VMTH Equine Field Service

(See also: Cardiology, Internal Medicine)

Dr. Morgan is an equine practitioner board-certified in Equine Sports Medicine and Rehabilitation in the Department of Medicine & Epidemiology with a 50% clinical appointment in the VMTH. Her laboratory focuses on the study of performance limitations in the horse with an emphasis in cardiovascular and musculoskeletal disease. Recent projects include evaluation of heart rate variability in horses with gastric ulcers and assessment of the effects of sedation on gait evaluation.

Several projects are available involving electrocardiography or echocardiography in the horse or evaluation of renin-angiotensin-aldosterone signaling in the horse. Students will gain experience with live animal studies and data analysis.

For more information and to discuss potential projects please contact Dr. Morgan at [email protected].
