I obtained the degree of medical doctor in the year of 1982, the one of master in sciences in the year of 1988 and the one of doctor in sciences in the year of 1993. The three degrees were granted by the Autonomous University of San Luis Potosí. I joined the Department of Physiology and Pharmacology in 1994 with the repatriation mechanism of the National Council of Science and Technology. My line of work is related to the physiology of the smooth muscle, initially of the smooth muscle of the airways and in the last years of the vascular smooth muscle and how the diabetes mellitus affects its functioning at the level of its contractile function and its capacity of migration. Likewise, we are interested in knowing how blood flow is detected by endothelial cells and how diabetes mellitus modifies this function. Graduate students trained in my laboratory under my supervision: masters: 14 and 3 who will graduate in one more year. PhD students: 3 and 2 who will graduate in the next 3-4 years. Postdoctoral students: 4.
