Current Research

Pre- and post-harvest stress physiology and secondary metabolites

We study the biosynthesis of secondary metabolites (phenolics, carotenoids, etc.) of potential use for their unique functional and bioactive properties under pre- and post-harvest stresses (wounding, gas composition, UV light, chemical elicitors, and others). Studies include compound identification, the key enzymes of the metabolic pathways, and the signaling molecules involved. In addition, we study and design strategies to extend the shelf-life of fresh produce while ensuring quality and safety.

Current Projects:

Bioactive and functional properties of phytochemicals from commercial and novel crops

We identify and characterize bioactive compounds from commercial and novel crops, as well as crops from breeding programs in the US for potential use in the food, dietary supplement, cosmetic, pharmaceutical and agrochemical industries. We conduct bioactive compounds discovery using and array of assays (anticancer, antimutagenic, cardiovascular, cosmeceutical, color potential, antimicrobial, and others), separation and fractionation methods, and chemical analysis (TLC, HPLC, MS). In addition, we study the stability of bioactive compounds and methods of extraction and separation.
