Research Interests:

My area of interest is in understanding the biological basis of plants’ adaptation to various stresses, especially exposure to antibiotics produced by soil bacteria.  I use a combination of large-scales studies and investigations focused on the antibiotic resistance gene Atwbc19 to understand the mechanisms involved. In so doing, I am particularly like to engage undergraduate students in research and share the excitement of our findings.
