I am a Professor of Infectious Disease at the Veterinary Population Medicine Department. I have dedicated my scientific career to zoonotic disease investigations at the cellular and molecular level. I am interested in the ecology and molecular evolution of infectious agents and how they are modulated by changes in host and environmental niches. My research is highly interdisciplinary and encompasses all aspects of cellular, molecular pathogen-host interactions and epidemiology and ecology of infectious disease and collaborations across the country and the globe. A translational aspect of my studies is the development of novel unambiguous disease detection platforms and applications into immunoprohyllaxis. Thus my scientific inquiry focuses on world’s greatest infectious diseases such as those caused by mycobacteria and influenza A.

Primary areas of my research, address questions on pathogen-host interactions and bacterial and/or evolutionary genetics and the development of resistance against antimicrobial agents. Implications of my research findings have further lent to development of genome-wide SNP analyses in Mycobacterium tuberculosis Complex and enhanced our understanding of disease character and outcome, and velocity of pathogen spread. Genomic epidemiology tools have also helped us understand interspecies transmission of pathogens in resource limited ecosystems. Pathobiological or biomedical studies to answer transmission questions and to identify most representative strains for optimal vaccine development will benefit from findings of our studies. Over the last 15 years, my research has taken a turn toward translational science. In this regard, I have applied basic molecular evolutionary and pathogenesis information to diagnostics and vaccine development. One major area of emphasis has been to develop pathogen/receptor specific biomarkers to enable detection as well monitor response to treatment. The second arm of translational research is in the development of pathogen-specific receptors or aptamers to enable detection and/or drug targeting. I have developed a pipeline of methods to select and validate DNA aptamers for this purpose. In addition to a strong scientific program, I have developed leadership skills via participation in team science as a part of large consortium grants, serving as a director of graduate studies for the last 8 years shaping the program into an integrated teaching-learning-clinical system of education, and as a mentor for multiple junior faculty helping negotiate and navigate through the tenure process. I have also played an integral role in helping build a strong international collaboration at the CVM at UMN.
