Research Interest

My laboratory is focused primarily on studying the mechanisms underlying neurologic disease in animals utilizing both spontaneously arising disease and experimental models in a variety of laboratory animal species. One current focus of my lab is in utilizing the dog as a model for human brain cancer, primarily meningeal and glial tumors. This is being done through a variety of histologic, immunohistochemical, and molecular studies in both the dog and cat. We are especially interested in determining the roles that novel gene mutations have in the genesis of canine and feline meningioma and are utilizing RNAseq to better understand the transcriptome of this tumor. We are also actively involved in studying the immune cell microenvironment in canine brain tumors in order to determine if a relationship exists between immune cell infiltration and postsurgical outcome. Other active areas of research in my laboratory include analyzing the RNA transcriptome of canine soft tissue sarcomas, a common, but understudied tumor, in the dog. Due to my expertise in nonhuman primate pathology, I maintain numerous collaborations with researchers throughout the country aiding in various research studies.

Biography/Professional Experience

I am an Associate Professor in the College of Veterinary Medicine and Section Chief for Anatomic Pathology. I am a diplomate of the American College of Veterinary Pathologists (ACVP). I received my doctorate in veterinary medicine from Cornell University in 2005 and entered a residency in veterinary anatomic pathology at Cornell University, completed in 2008. I joined the faculty at the New England Primate Research Center, a division of Harvard Medical School as a research associate in 2008. I had achieved assistant professor by 2013 and held an appointment in the Pathology Department of the Massachusetts General Hospital during my tenure at the primate center. I joined the faculty in the Section of Anatomic Pathology as an Assistant Professor at Cornell University in fall of 2013. I have a strong interest in training veterinary students and pathology residents and preparing them for a career in comparative veterinary pathology. I believe that this is best done through hands on exposure to clinical cases and basic research techniques. I am involved nationally in the ACVP and other pathology groups including the Canine Brain Tumor Consortium, a multidisciplinary group organized through the National Cancer Institute. I strongly believe in the integration of teaching and collaborative research as a way to foster continued growth in the field of comparative veterinary pathology.
