Beginning Monday, June 14, 2021, the MSU Veterinary Medical Center will allow clients into the building with patients. Find details here.

Any patient presented to the MSU Small Animal Emergency Service will undergo an initial medical evaluation to determine if urgent care is needed, and whether hospitalization is warranted. The MSU Small Animal Emergency Service will only hospitalize patients that our clinicians consider to be unstable or to have life-threatening conditions.

Dr. Ravi and her team develop computational approaches to study the molecular basis of pathogenesis and intervention of infectious diseases.

The research involves developing computational approaches that can leverage large-scale genomic data to gain actionable insights into infectious disease biology. Specifically, with a focus on three key areas:

i) unraveling molecular mechanisms common between non-infectious and infectious diseases, to guide targeted drug repurposing,

ii) identifying genomic signatures, functions, and mechanisms relevant to host-pathogen interactions, to enable understanding and guide diagnosis, and

iii) developing tools and resources for seamlessly relating sequence, structure, and function of genes/proteins in poorly characterized pathogens.
