He received a degree  in Communications and Electronic Engineering (Professional degree), a M.S.E.E. from the National Polytechnic Institute in Mexico City and a Dr.-Ing degree form the University of Stuttgart in Stuttgart, Germany in 1974, 1976 and 1982 respectively. He was professor at the National Institute for Astrophysics Optics and Electronics (INAOE) and at Texas A&M University. His research is related to various aspects of design and test of analog and mixed-signal Very Large Scale Integrated Circuits. He has made numerous contributions to this field which have been reported in over four hundred   publications in the most prestigious journals and conferences in analog circuit design. He has two high technology patents and has held numerous invited and keynote presentations. He has been a consultant to Texas Instruments, NASA-ACE, NASA-Ames and Oak Ridge National Laboratories. His research has been supported by National Science Foundation, Sandia National Labs, Engineering Foundation, Texas Instruments and Agilent. He received the prestigious URC University Research Council for exceptional achievements in creative scholarly activities and the Westhafer award for Excellence in Research and Creativity in  March and May 2002 respectively. The Westhafer award is  the highest faculty award for research merits at  New Mexico State University. On October 2002 he was named Paul W.  Klipsch Distinguished Professor and was IEEE distinguished lecturer for the period 2003-2005.  Two of his papers were listed in 2005 among the 100 most downloaded papers of all IEEE  societies. In May 2004 one of his  students earned the award as most outstanding Ph.D student and  in 2006 and 2007 two of his students earned the award as most outstanding M.Sc. students at New Mexico State University
