He received his Bachelor's degree in mechanical engineering from Universidad Nacional de Trujillo (Perú), M.S. in mechanical engineering, and Ph.D. in chemical engineering degrees from the University of Puerto Rico – Mayagüez campus. After graduate school, he joined the University of Florida as a post-doctoral research associate for two years. Prior to joining UAH, Dr. Torres Díaz worked as a Postdoctoral Fellow at Johns Hopkins University in the Department of Chemical and Biomolecular Engineering. Dr. Torres Díaz research interests are centered on the fundamental phenomenological behavior and applications of colloidal suspensions composed of anisotropic particles and suspensions with a polar behavior generated by the influence of an external field. We use novel approaches to model anisotropic colloids by quantifying their interactions that depend on their relative position and orientation. The quantification of the directional behavior generated by anisotropic particles will improve the current applications, such as controlling the directed assembly, micro- and nano-robots, tunable (soft) materials, active suspensions, anti-fouling surfaces, colloidal delivery systems, separation processes, magneto-rheological fluids, etc. Personal Website Education Ph.D., Chemical Engineering, University of Puerto Rico at MayagÜez - 2012 M.S., Mechanical Engineering, University of Puerto Rico at MayagÜez - 2007 Bachelor of Mechanical Engineering, Universidad Nacional de Trujillo, Peru - 2004.
