A native of Mexico, he attended Texas Southmost College in Brownsville before transferring to Sul Ross State University, where he earned a bachelor’s degree in chemistry in 1987. He then moved to Denton where he completed his graduate degrees in analytical chemistry.

As lab supervisor he provided training and assistance in the use of the equipment and is credited in many theses and dissertations over the years, especially for his expertise in mass spectrometry.

Over the years, the family created and supported many programs that serve students, UNT and the Latino community.
