Education Details
PhD in Microbiology (2007) - University of North Dakota, USA
Masters in Microbial Gene Technology (2002) - Madurai Kamaraj University, India
Bachelors in Microbiology (2000) - University Of Delhi, India
Professional Experience:
2010-2012 - Post-doctoral Fellow, Forsyth Institute, (affiliated to Harvard School of Dental Medicine), USA
2007-2010 - Post-doctoral Associate, Yale University, USA
Research Area:
Our lab research work is focused on elucidating the mechanism of cell wall biogenesis and its role in bacterial physiology and diseases. We are working on the following areas:
  1. Bacterial cell wall morphogenesis:Currently my lab is working on cell division and morphogenesis of bacterial cell using Caulobacter crescentus as a model system. Our understanding of bacterial morphogenesis and cell division has progressed significantly from earlier days, however, there are number of important questions which are still unanswered. My broad research goal is to uncover the spatio-temporal regulation of cell wall synthesis in bacteria. Complete understanding of the bacterial cell wall machinery would provide a significant edge towards our fight against disease causing pathogenic microbes.

  2. Bacterial Biofilms:The other area my lab is interested in is microbial interactions and the focus of the study is in understanding the microbial communities present in various environments. Currently, we are trying to understand the microbial interactions in periodontal biofilms. Our research is focused on elucidating the role of probiotic lactobacilli in inhibiting periodontal diseases.
    The lab is also studying the role of cell wall hydrolases in biofilm formation in pathogens such as, E. coli and Staphylococcus aureus. We are also studying the role of cell wall hydrolases in Biofilm Formation of Staphylococcus aureus, and this project has been funded jointly by DUKE and SNU.

  3. Microbial biodiversity and beneficial microbes: .The other area my lab is interested understanding the microbial communities present in various environments. Currently, we are trying to understand and establish the bacterial communities present in aquatic and soil habitats.
