  • Member of four professional body.

Research Collaboration:

  • I have established research collaboration with more than 10 international scientists working in State University (India, Finland, Australia and USA) and CGIAR institute.

Authorship of scholarly work:

  • Authored 40 peer-reviewed journal articles and 8 book chapters. My work has been cited more than 1030 times; and three of my seminal discoveries have been cited more than 100 times each (h-index: 16).  Presented abstracts at 24 national and international conferences in my area of research.

Judge of work of others:

  • Reviewer of eight major journals of plant sciences

Original contributions of major significance in the field:

  • For the first time quantified the effects of short episode high temperature stress on pollen and ovary functions in sorghum and wheat.
  • Decoded mechanisms of reproductive failure in sorghum and soybean under high temperature stress during pre and post anthesis stage.
  • Identified for the first time the lipid signal molecule responsible for maintain the pollen tip polarity and its function under high temperature stress. I have pioneered the development of a high-throughput screening tool for identifying crop varieties more tolerant to abiotic stresses using in-vitro probes.
  • High temperature stress resulted in increased production of ethylene, which causes premature leaf senescence, and flower and pod abortion. This effect can be reduced by foliar application of a chemical named as 1-MCP.  This key finding has proved valuable to soybean growers everywhere, to increase seed yield.
  • First to identify the primary mechanism of high temperature stress effect i.e., through oxidative damage.
  • First, to identify that selenium can acts as an antioxidant in soybean and sorghum under stressful environment. Foliar spray of selenium was proved to work under field conditions.
  • Decoded mechanism of salinity tolerance in rice and identified technology to improve the salinity tolerance.
  • Dissected the mechanism of chromium tolerance or susceptibility at the physiological and molecular levels has made the way to bioremediation. Based on this finding, a sorghum variety was identified which is less susceptible to chromium damage is now grown in areas which have higher soil chromium content.
