Significant Research Contribution
Developmental Biology and DNA repair mechanisms in cyanobacteria.
DNA repair in E. coli and bacteriophages. A new gene locus, rer, was identified which facilitated repair of UV-induced damage by regulating the coordination between repair of damage and replication . The rer gene has been incorporated on the linkage map of E. coli.
Pathogenesis of cholera. Landmark discovery on demonstration of expression and modulation of cholera toxin biosynthesis by plasmids (Nature, 1978) and adhesive protein of V. cholerae for binding to intestinal mucosa and the concept of the subunit vaccine in experimental cholera.
Tuberculosis. Identification and development of a reliable reagent for early diagnosis of TB, user friendly non hazardous genetic screens for antitubercular compounds, strategies to identify genes which are important for tubercle bacilli to survive in the host and role of mycobacterial lipase in virulence and modulation of host immune response.
