Biography

Dr. Padua received a B.S. in Biochemical Engineering from the National Polytechnic Institute in Mexico City. She became interested in food science while working as a research assistant in a project dedicated to the re-engineering of tortilla flour production starting from high lysine corn. She later obtained her M.S. and Ph.D. degrees in Food Science from the University of Illinois at Urbana-Champaign. Dr. Padua joined the UIUC faculty in 1996. Her research interests focus on the structure and properties of novel bioderived materials for food, agricultural, and biomedical uses. She has published extensively in this area and has patented her results. Her work has been supported by federal agencies and industry groups. She serves on the editorial board of Journal of Food Process Engineering.
