I am a plant physiologist and am working on various aspects of plant physiology to improve crop yield, particularly photosynthesis. Under abiotic stress conditions, the efficiency of photosynthesis decreases drastically leading to lower crop yield. We use a non-invasive tool of measuring Chlorophyll a fluorescence kinetics to get information about the photosynthetic efficiency of the plants. The technique is fast, reliable and can be carried out in field conditions without destroying the plant. We have worked on several stresses including salinity, drought, high temperature, heavy metal, UV light, and environmental pollutants. My lab is also engaged in using Arbuscular mycorrhizal fungi to improve stress tolerance in Maize plants. Another focus of my research is using suitable seed priming method in wheat crops to improve overall productivity and stress tolerance. One more research topic of my lab is related to bio-degradation of polycyclic aromatic hydrocarbons (PAH) using bacteria and algae. Removal of these pollutants also results in better plant growth in contaminated soil.
