Dr. Atamian’s research interests broadly aim at understanding the molecular mechanisms of plant interactions with the environment. These include biotic interactions (insects, bacteria, fungi, nematodes) and various biotic stresses (drought, cold, heat) as well as daily environmental fluctuations. He uses high throughput sequencing and molecular approaches together with physiological field experiments to better understand plant genotype x environment interactions.
