Solmaz Tabtabaei

Associate Professor

  • Department of Chemical Engineering, CEA
  • College of Engineering and Architecture (CEA)


Dr. Solmaz Tabtabaei received her PhD degree in Chemical Engineering from the University of Toronto (Canada). There she conducted experimental and theoretical work to develop a new and sustainable process that simultaneously produces biodiesel and food-grade protein isolates from an underutilized feedstock. She has been granted the “Global Engineering Leaders Award” from the University of Toronto based on her publication records, remarkable research and extracurricular accomplishments during her PhD studies. In November 2014, Solmaz received MITACS Elevate Postdoctoral Fellowship and moved to the University of Waterloo (Canada), where she began her work in developing solvent-free tribo-electrostatic bioseparation approach for production of plant protein concentrates as well as carbohydrate-rich biomass for biofuels. Dr. Tabtabaei is currently an assistant professor of Chemical Engineering at Howard University, Washington DC. She enjoys working on bio-separation processes, food and biofule-related engineering projects, reaction engineering, and 3D food printing.
