Blackland Road Temple, Texas 76502 RESEARCH INTERESTS My research emphasizes improving dryland cropping systems by alleviating genetic and cultural constraints to productivity. Identifying superior cultivars, genetic traits, and management practices that maximize efficient water and nutrient use are of primary interest. Crops include: cotton, winter wheat, corn (maize) and grain sorghum. Investigations on ultra-narrow row cropping systems to optimize water and nutrient use are in progress. Uses of site-specific crop management practices are of interest. Research includes validation and use of crop models to minimize agricultural production risks. Other interests include identification of physiological and genetic mechanisms that enhance plant water-use efficiency and carbon assimilation. EDUCATION B.S. Texas Tech University, Lubbock, TX M.S.
