Ryan Hartman

Assistant Professor

Chemical and Biomolecular Engineering


Ryan L. Hartman is Assistant Professor in the Department of Chemical and Biomolecular Engineering.  He completed his postdoctoral research in the Department of Chemical Engineering at the Massachusetts Institute of Technology, Cambridge.  He earned his Ph.D. and M.S.E. in Chemical Engineering from the University of Michigan, Ann Arbor and his B.S. in Chemical Engineering from Michigan Technological University, Houghton.

Hartman’s laboratory investigates flow chemistry with microsystems using chemical reaction engineering principles for sustainable chemicals, energy, and healthcare.  His laboratory’s research has been featured in Chemical & Engineering Technology, Industrial & Engineering Chemistry Research, the Journal of Flow Chemistry, Organic Process Research & Development, Lab on a Chip, Reaction Chemistry & Engineering, and at conferences and seminars worldwide.  He is the Reaction Engineering Programming Chair of the American Institute of Chemical Engineers.  He is also co-inventor of twelve U.S. Patents, sixteen U.S. Patent Applications, and his contributions have helped to enable natural gas production and the continuous manufacture of fine chemicals and pharmaceuticals.

Previously, Hartman was Assistant Professor and Reichhold-Shumaker Fellow in the Department of Chemical and Biological Engineering at The University of Alabama, Tuscaloosa.  He was recently honored as Visiting Assistant Professor of the Institut de Chimie de la Matiere Condensee de Bordeaux CNRS, Universite de Bordeaux.  He is also a winner of the NSF CAREER Award and member of the National Academy of Inventors.  Undergraduate researchers in his laboratory have won prestigious honors, such as the NSF Graduate Research Fellowship Program Award and the Barry M. Goldwater Scholarship and Excellence in Education.  Students K-12 have also gained local, state, national, and international recognition for their senior thesis research in his laboratory.  Hartman returned to academia following his private sector career with Schlumberger Limited.
