David Velázquez Fernández

David Velázquez Fernández is a Mexican surgeon and researcher attached to the Endocrine Surgery and Advanced Laparoscopy at the Department of Surgery of the Salvador Zubirán National Institute of Health Sciences and Nutrition and with the Clinic of Nutrition, Obesity and Metabolic Disorders at the ABC Medical Center. He studied medicine at the Universidad Veracruzana, and received his doctorate from the Karolinska Institutet in Stockholm, Sweden.

He specializes in three areas of work. The first two are healthcare and surgery, giving consultation to patients with endocrine disease as well as general surgery. The third area is research, with several projects both clinical and basic research in genomic medicine related endocrine tumors a genomic of polygenic obesity. He teaches various medical schools including the Monterrey Institute of Technology and Higher Education, Mexico City, the National Autonomous University of Mexico, the National Polytechnic Institute, the North-east University (UNE) at Tampico and the ABC Medical Center and the Salvador Zubirán National Institute of Health Sciences and Nutrition (INCMNSZ).

Life David Velázquez Fernández was born on March 13, 1969, in Córdoba, Veracruz, the second son of Bernardino Velázquez Sánchez and Maria de la Paz Fernández Castañeda. He lived his first five years in Córdoba with his four siblings. Then he moved to Orizaba, Veracruz, remaining there until he was nineteen years old.

He decided to study medicine because of his father, who is an orthopedic surgeon. His father used to buy him anatomy and surgery books, and take him to work. These actions installed in him a love for anatomy and surgery. with an average grade of 98.5/100 graduating cum laude. Later he did his required community service in medical research at INMCNSZ, in the medical genetics department for one year. Velázquez continued his studies with a masters in medical sciences from UNAM-INCMNSZ. He concluded it in 2004 with a unanimous approval.

He received the Travel Award from the IAES in Durban, South Africa in 2005 and the Appreciation of the National Mexican Congress for participating in the Mexican HapMap Project in 2009. He received the "Gustavo Baz Prada" Award for best social service project by the UNAM in 2003.

Currently he advises endocrine disease patients who require surgery and general surgery. He works in clinical and basic research projects in genomic medicine of endocrine tumors an genomic of polygenic obesity. He teaches at the ITESM Campus Ciudad de México, at the masters and PhD program in medical sciences, dental and health of the National Autonomous University of Mexico (UNAM), at the Instituto Politécnico Nacional (Master of Clinical Research program), at the ABC Medical Center and as associate professor of High Specialty Course Endocrine Surgery of the UNAM at INCMNSZ.
