Dr. Roberto Guzman has been a Chemical Engineering professor at the University of Arizona since 1989. He has faculty joint appointments in Biomedical Engineering and in Pharmacology and Toxicology (recently) Departments at the University of Arizona. He also has an academic appointment as an international faculty in the Nanotechnology Program at the University of Sonora, Mexico. He has been a visiting professor at the University of Guanajuato, Mexico, at the University of Uppsala, Sweden and at the University of Technology in Compiegne, France, where he also has a visiting scholar appointment. He received a PhD in Chemical Engineering/Biotechnology from North Carolina State University (NCSU) where he continued as a postdoc for a year before joining the University of Arizona. He received an MSc in Chemical Engineering from the University of Illinois, Chicago and a B.S. in Chemical Engineering from the University of Guanajuato, Mexico. His present research is in Nanoparticle Bio/Technology and protein purifications with emphasis in metal-hybrid nanoparticles for diagnostics and target drug delivery therapy and discovery of biomarkers from biological fluids. Professor Guzman background has strong bases in molecular recognition, affinity technology, synthetic chemistry, applied biochemistry and mathematical modeling. The areas of research studied in his laboratory fall in the boundaries between synthetic chemistry, biology, medicine, polymer sciences and engineering and incorporate both experimental and theoretical work analysis.
