MSU GI GROUP Faculty Members
-
Dr. Harry Cridge
Associate Professor of Small Animal Internal Medicine
Dr. Cridge is an ACVIM and ECVIM board-certified specialist in small animal internal medicine. He is also one of just 3 people recognized by the RCVS as a specialist in gastroenterology worldwide. Dr. Cridge's research is focussed on the etiology, diagnosis, and treatment of exocrine pancreatic disorders. He also performs some research into gastrointestinal complications of systemic disease.

Dr. Victor DiRita
Rudolph Hugh Endowed Chair in Microbial Pathogenesis and Department Chair, Microbiology
Our group studies pathogenicity mechanisms of GI microbes such as Campylobacter, Vibrio, and Enterobacter. We are interested in host processes that influence fitness of microbial pathogens in the gut.
-
Dr. Julia Ganz
Associate Professor
Our lab studies the cellular-molecular mechanisms and gene regulatory programs that control the development and regeneration of the enteric nervous system - the brain in the gut - and how these processes are affected in gut diseases.

Dr. Brian Gulbransen
MSU Foundation Professor
The goal of my research is to understand how inflammation in the nervous system (neuroinflammation) leads to long-term changes in neural circuitry. Within this context, we focus on the regulation of neural networks by glial cells, with particular interests in clarifying the roles of glial cells in nervous system physiology and elucidating how glial changes during neuroinflammation contribute to the plasticity of neural circuits. We are addressing this issue by exploring how neuron-glia interactions in the enteric nervous system (ENS) regulate gut physiology. Our studies incorporate a number of cellular imaging approaches with chemogenetics to record and control cell activity, transgenic models to perturb cellular functions, genomic sequencing, and functional assays. These approaches are complimented by cell, organ, and whole animal assays to understand how glia impact gut functions and visceral sensitivity.

Dr. Sara Jablonski
Assistant Professor
Sara Jablonski, DVM, PhD, DACVIM (SAIM), is a clinician on the Internal Medicine Service at the Michigan State University Veterinary Medical Center. She also serves as an Assistant Professor for the Department of Small Animal Clinical Sciences at the Michigan State University College of Veterinary Medicine. Jablonski received her DVM from Colorado State University (CSU) in 2011; she went on to complete a small animal internal medicine (SAIM) residency at the same establishment in 2016, and followed this by completing a PhD studying canine protein-losing enteropathies. She is a diplomate of the American College of Veterinary Internal Medicine (ACVIM), and was a faculty member at CSU College of Veterinary Medicine and Biomedical Sciences prior to joining MSU’s faculty in 2020. She has also served on the board of the Comparative Gastroenterology Society since 2019.

Dr. Kwangwook Kim
Assistant Professor
Our laboratory evaluates how nutrients impact swine growth, immune function, and metabolism. We use advanced techniques to assess the effects of feed additives and dietary components on swine health and productivity, aiming to identify practical solutions for producing safe, sustainable, and nutritious pork products. Using swine models, we also gain insight into human health issues and investigate potential treatments that benefit both the swine industry and human health.

Dr. Rebecca Knickmeyer
Associate Professor
Dr. Knickmeyer's research focuses on understanding how genetic and environmental factors influence the development of brain morphometry, anatomical and functional connectivity, and cognitive and emotional function in infancy and early childhood. She has a particular interest in the early development of microbiome-gut-brain axis. She uses gnotobiotic mice, human clinical samples, neuroimaging, and neurobehavioral techniques to understand how microbes contribute to risk for anxiety, depression, and autism spectrum conditions.
-
Dr. Geoffroy Laumet
Assistant Professor
Our lab studies the communication between sensory neurons and immune cells and how such communication contributes to the development and the resolution of chronic pain.

Dr. Amelia Munsterman
Associate Professor
Dr. Munsterman is a large animal surgeon and criticalist, with interests focused on equine gastrointestinal motility disorders. Her research includes measurement techniqies for intra-abdominal pressure and the effects of intra-abdominal hypertension biomarkers and perfusion. Additional investigations include the diagnosis and treatment of intestinal motility disorders with electrointestinography.
