Scientific Activity

My lab is interested in understanding the mechanisms of attack and defense in the interaction between plants and their pathogens. Our model is the interaction between the bacterial pathogen, Xanthomonas oryzae pv. oryzae (Xoo) and it’s host plant which is rice. A major focus of our current research is to identify the rice functions that are involved in induction of innate immunity and Xoo effector proteins that work inside rice cells to suppress innate immune responses. Of particular interest are immune responses that are induced by Xoo secreted rice cell wall degrading enzymes. In addition, we are using molecular marker/genomics assisted selection methods for improvement of rice cultivars for enhanced biotic stress tolerance.

Teaching Activity

Involved in teaching courses in Genetics and Plant Stress Biology to advanced undergraduate and doctoral students, and a basic course in Molecular Biology and Genetics to second-year undergraduate students.
