Carl J Rees Professor Emeritus of Mathematical Sciences at the University of Delaware

Newark, Delaware, United States

About

My main research direction is for mathematical models for the tear film on the front of the eye and the ocular surface. This is a formidable challenge in mathematical modeling and computation. Although officially retired, I am doing some consulting in this area in the near term.

Experience

    • Professor of Mathematics
      Aug 1995 - Aug 2024 · 29 yrs 1 mo

      Besides my teaching and service, I work on mathematical models for tear film dynamics. I work with colleagues and students to do this. My colleagues range from experimentalists and optometrists to undergraduate math, engineering and quantitative biology students. The mathematical models are for thin fluid films ("lubrication theory") that are solved numerically on a computer. The models may include fluid motion, heat transfer, solute (osmolarity) transfer, evaporation and other effects. I've also started working with students to incorporate the effect of the evaporating tear film on the cells in the ocular surface. Including some biology into the modeling is an exciting and new challenge. I'm also have affiliated faculty positions in the Data Science Institute, the Department of Biomedical Engineering as well as the Center for Bioinformatics and Computational Biology.

  • Associate Director at Institute for Mathematics and Its Applications, U of Minnesota
    Jul 2013 - Jun 2014 · 1 yr

    In this one-year position, I helped run the many workshops and help run the day-to-day operations. I was also a Visiting Professor in the School of Mathematics during this time.

  • Mathematician at NIST
    Oct 1991 - Jul 1995 · 3 yrs 10 mos

    I was an NRC postdoctoral fellow for two years and a staff mathematician for two years. I studied phase change, fluid flow and their interaction while I was there. I worked under the guidance of Jeff McFadden in the Mathematical and Computational Sciences Division.
