Juan Carlos Cruz received his undergraduate degree in Chemical Engineering from the National University of Colombia (2002), and his doctorate in Chemical Engineering from Kansas State University (2010) for work on a novel platform for enzyme immobilization to address challenges in non-aqueous biocatalysis. He was then a Postdoctoral Research Fellow at The Johns Hopkins University in the Department of Materials Science and Engineering (2010-2011). At Johns Hopkins, Cruz developed a number of projects focused on state-of-the-art biophysical techniques to answer compelling questions in protein-lipid interactions. Cruz received the 2002 Award for the Best Undergraduate Thesis, recognizing the development of a bench scale biodesulfurization process for middle distillate fuels from the Colombian Association of Chemical Engineers. At K-State he received the Honstead and the Goering Engineering Scholarships in 2007. At K-State he was also inducted into the Phi Kappa Phi Engineering Honor Society in 2008. In 2012 Cruz joined the Bioengineering Program at Universidad de Antioquia. Cruz is a member of the American Institute of Chemical Engineers and the Biophysical Society. Dr. Cruz serves as reviewer for Bioresource Technology, Journal of Molecular Catalysis B and Journal of Biotechnology. Dr. Cruzes´ research interests include: biophysical engineering techniques to characterize and the nano-bio interface; peptide chemistry and engineering; nanobiotechnology for industrial and biomedical applications; novel nano-bio hybrid systems for applications in biosensing and biomolecular electronics; non-aqueous enzymology and the science and engineering of renewable energy systems. Dr. Cruz leads initiatives concerning nano- and biotechnology in the Bioengineering Program.
