My research focuses on modeling and simulation of problems in material science and system biology. In materials, I am interested in grain growth where texture and grain boundary character are the main statistical properties. Their relations to material properties are one of the current efforts. Using inverse problem formulation in conjunction with HEDM data from R. Suter Lab I look into validation of classical models and their extensions. In addition I am interested in theories that bridge between models at the single grain level and theories for statistical properties. The work involves collaboration with D. Kinderlehrer and of materials science faculty at CMU.

In biology I am interested in system level problems related to immune response and physiology, especially the circulatory system. Real data from human subjects and animals is driving the questions and the mathematical approaches to be developed. Current interest include understanding of failure mechanisms in shock (hypovolemic and septic). I am interested in developing real time systems for monitoring and predicting instabilities based on mathematical models.
