Biography
Eric Kostelich is interested in nonlinear dynamics, uncertainty quantification, and mathematical biology. He is one of the principal developers of a computationally efficient and very accurate method for estimating the initial conditions of numerical weather models from sparse sets of noisy observations, a procedure called data assimilation. Kostelich has been working on related problems in data assimilation for “space weather” in the ionosphere. In addition, he has written papers on data assimilation for mathematical models of the growth and treatment of cancer, especially prostate cancer and malignant glioma and related forecasting questions, such as the likely duration of treatment response. He has coauthored (with Professor Dieter Armbruster) an undergraduate textbook on differential equations.
Education

Research Group
Professor Kostelich directs the Mentoring Through Critical Transition Points (MCTP) program at ASU in partnership with Maricopa Community Colleges, which is funded by the National Science Foundation. This program provides intensive summer research experiences and a research seminar during the academic year for selected mathematics majors.
