Research areas

Microbial Ecology (Mycorrhizal fungi, PGPR, Endophytes, Frankia, and plant Pathogens), Biodiversity and Molecular Biology of Microbes.

Research Interests

My research interest is in the area of Microbial Ecology. The main goal of my research is to study the diversity and ecophysiology of microorganisms with special reference to some important groups like AM fungi, PGPR, endophytes, phosphate solubilizers etc. within selected environmental systems and to decipher their interactions among each other and with plants. Most of the ecosystems are characterized by uncultured microorganisms. Characterization of these unexplored microorganisms is crucial for understanding the microbial ecology of these systems. These will help us to improve our lives via the use of microbes in environmental restoration, food production, and development of useful products such as antibiotics etc. The study of these bizarre and diverse creatures that are everywhere yet nowhere to be seen is fascinating and a pursuit that appeals to the curiosity and playfulness in us.
