Computational Systems Biology of Infectious Diseases

We develop computational approaches to study the molecular basis of pathogenesis and intervention of infectious diseases.

Our research involves developing computational approaches that can leverage large-scale genomic data to gain actionable insights into infectious disease biology. Specifically, we 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.

PI

I am a computational biologist at the Dept. of Pathobiology and Diagnostic Investigation, Michigan State University. I work on protein sequence-structure-function relationships, comparative genomics, and drug repurposing as they relate to infectious diseases.

I also teach data analysis and visualization and /Python programming to diverse groups in non-traditional settings. As part of this effort, I founded R-Ladies East Lansing and Women+ Data Science, through which we host our meetups & webinars!
