Ryan Hartman

The Hartman Research Laboratory investigates impactful problems related to sustainability through application of chemical reaction engineering principles.  There is a need for autonomous laboratory-scale flow reactors that can high-throughput screen and generate sufficient experimental data to decipher reaction kinetics and mechanisms.  Integration of in-situ spectroscopic methods with microfluidics and their automation creates the possibility of computers working synchronously with a handful of key experiments.  Thus, the design of artificial intelligence and machine learning methods with continuous-flow microreactors for faster discovery has become a central theme in most of our research.  Rethinking how we perform laboratory experiments can reduce the chemical waste, energy requirements, make experiments safer, and it can yield molecular-scale information needed for predictive models for applications in chemicals, energy, healthcare, and materials towards a sustainable future.

Ryan L. Hartman is Associate Professor in the Department of Chemical and Biomolecular Engineering in the NYU Tandon School of Engineering. Prof. Hartman completed his postdoctoral research in the Department of Chemical Engineering at the Massachusetts Institute of Technology (Cambridge), his Ph.D. in Chemical Engineering from the University of Michigan (Ann Arbor), and his B.S. in Chemical Engineering from Michigan Technological University (Houghton). He has served in the Tenured/Tenure-Track Faculty Senate Council of New York University and the Faculty Executive Committee of NYU Tandon.  He has also filled various executive leadership roles for the American Institute of Chemical Engineers (AIChE), the President and Member of the Executive Board of Directors of the International Symposia of Chemical Reaction Engineering (ISCRE), and a Member of the Advisory Board of Reaction Chemistry & Engineering, a Royal Society of Chemistry Journal.  He is a thrust lead in the Center for Decarbonizing Chemical Manufacturing Using Sustainable Electrification (DC-MUSE).  He has been honored as Visiting Professor at Dow, Inc., Visiting Assistant Professor of the Institute of Condensed Matter Chemistry of Bordeaux (ICMCB) CNRS, winner of the NSF CAREER Award, and a member of the National Academy of Inventors.  Hartman returned to academia following his private sector career with Schlumberger Limited in which he developed energy technology.
