About Research

Our research focuses on the development and use of novel systems approaches to analyze high-dimensional immunological datasets, and elucidate mechanisms of immune regulation and dysregulation. Our previous work has utilized systems approaches to analyze Mendelian mutations in the context of three-dimensional protein-protein interaction networks, to understand molecular mechanisms of corresponding disorders. We have also developed network analyses frameworks to characterize the evolutionary dynamics of these protein networks. Another dimension of our past work has been the use of statistical methods for the analyses of high-dimensional data and machine-learning approaches to elucidate correlates of natural and vaccine-mediated immunity in HIV, tuberculosis and malaria.
 
We are currently working on using network systems and functional genomic approaches to perform multi-scale integration of genomic and epigenomic datasets with biological networks to identify molecular phenotypes underlying these immunological disorders. We also use statistical and machine-learning techniques to integrate multi-omic datasets (genomic, transcriptomic, proteomic, metabolomic and antibody-omic) and elucidate molecular mechanisms of immune regulation and dysregulation. We currently have several federally funded projects focusing on infectious diseases as well as autoimmune and alloimmune disorders. We were fortunate to recently receive a NIAID New Innovators DP2 Award. Our lab (www.jishnulab.org) is highly interdisciplinary and provides a dynamic training environment.
