BS, York College of Pennsylvania; MS, Ph.D., University of Delaware


Dr. Cromer received his B.S. in Mathematics from York College of Pennsylvania in 2005, and his Ph.D. in Applied Mathematics from the University of Delaware in 2011. During his time in Delaware, he spent several months at the Institute for Mathematics and its Applications at the University of Minnesota during a special semester on complex fluids, and was awarded the University Dissertation Fellowship. Upon graduation, he was a postdoctoral scholar in Chemical Engineering and the Materials Research Lab at the University of California, Santa Barbara 2011-2013. In 2013, he was awarded a National Research Council Research Associateship and spent the following year conducting research at the National Institute of Standards and Technology. He began teaching at Rochester Institute of Technology (RIT) in 2014. His research focuses on the modeling, analysis, and simulation of complex fluids. He is interested in a wide range of materials (e.g., wormlike micellar solutions, polymer solutions, and colloidal dispersions), which have a wide range of applications (e.g., oil recovery, soft body armor, materials processing).

Currently Teaching

4 Credits
This is the first in a two-course sequence intended for students majoring in mathematics, science, or engineering. It emphasizes the understanding of concepts, and using them to solve physical problems. The course covers functions, limits, continuity, the derivative, rules of differentiation, applications of the derivative, Riemann sums, definite integrals, and indefinite integrals.
0 - 9 Credits
Masters-level research by the candidate on an appropriate topic as arranged between the candidate and the research advisor.

    RIT seniors use mathematical modeling to explore COVID-19 questions for policymakers

    Mathematical modeling has been a powerful tool for policymakers grappling with COVID-19 to help predict how targeted actions can impact the rates of infections, minimize the risk of exposures, increase recovery rates, and much more. Fifteen seniors who took the Senior Capstone in Math course this spring put their modeling skills to the test to help officials evaluate past policies and predict future outcomes.
