Research Interests

I am most interested in the relationship between the environment and the physiological and molecular response in plant systems. My work focuses on abiotic stress and biotechnology in crop systems with a concentrated interest in cotton and hemp. My favorite plant gene is RCA, a rubisco activase responsible for the biochemical limitation of photosynthesis during water deficit and heat stress.

My research interests are in abiotic stress tolerance and crop improvement. My current focus is on hemp and cotton for drought, heat and salt tolerance and looking at how a Rubisco Activase gene can improve crop yield. I use tissue culture techniques to combine stress tolerant genes to genetically engineer abiotic stress tolerant plants. My hemp project is a focus on flower timing and maturity. Other small projects look at mycorrhizae association and drought and heat tolerance.

My work at Texas Tech addresses the effects of climate change and agriculture productivity to improve crops not only for the Texas southern high plains but also a global impact.

 My previous research experience includes plant breeding work for abiotic stress tolerance in peanuts, high oleic and linoleic peanut lines, ornamental horticulture salinity stress in long stem rose, landscape performance trials for the urban environment, and human forensics.
