Research & Extension Interests

Breeding of dry bean varieties to select plants that are resistant to rust, white mold, common bacteria blight, and root rots; that have desirable qualities related to water efficiency and minimum tillage systems; and that have a more upright architecture, allowing direct harvesting.

At North Dakota State University he worked as a graduate research fellowship in the six-row barley breeding project. While pursuing his master's degree at the University of Puerto Rico, he identified a marker that has been used extensively to introgress BGYMV resistance in dry and snap beans. He also worked on markers for tagging resistance to Macrophomina and common bacterial blight, and collaberated on a research project to develop an RAPD linkage map of disease resistance alleles and QTL in dry bean. Prior to that, as a research assistant in the breeding and genetics program at the International Center for Tropical Agriculture at Cali, Colombia, his work resulted in the release of six small and medium-seeded common dry bean cultivars possessing multiple-disease resistance in Argentina, Brazil, Bolivia and Mexico. He received a bachelor of science degree from Universidad Nacional de Colombia. Prior to joining the staff at the Panhandle Research and Extension Center in April 2005, Carlos spent nearly two years in Nepal, leading a project to develop high-quality varieties of maize that will grow on hillsides, to help alleviate malnutrition in that country. Prior to Nepal, he worked as a research associate scientist at the International Center for Maize and Wheat Improvement (CIMMYT) in Mexico, where he developed new subtropical varieties and hybrids of corn.
