Katya Rigatto attained her Bachelor of Veterinary Sciences, from the Universidade Federal de Pelotas, College of Veterinary Science, Brazil. In 2001, she received her Ph.D. in Physiology from the Universidade Federal do Rio Grande do Sul (UFRGS), Brazil with a scholarship from CAPES. Immediately, she got a Postdoctoral fellowship in the Department of Pharmacology and Toxicology, at Wright State University, to study the “Hormonal control of Blood Pressure in a new genetic strain.” On August 14, 2001, Katya received from the American Heart Association the Merck New Investigator Award: “Excellence in High Blood Pressure Control”. From 1993 to 2004, Katya served as a Professor at the Universidade Federal de Pelotas (UFPel)-RS-Brazil. In 2010, she was a Visiting Professor at the University of Florida using the hemodynamic, molecular and biochemical analyses to study the brain signaling mechanisms involved in a novel therapy for monocrotaline-induced pulmonary hypertension. Currently, she is a professor at the Universidade Federal de Ciências da Saúde de Porto Alegre, Brazil and she gets a CNPq Productivity Award.
