Research interests + projects

Our group carries out research in three broad areas: mechanics of biological cells and tissues, interfacial fluid dynamics, and mechanics and rheology of complex fluids. Our work has an interdisciplinary flavor, crosscutting applied mathematics, cell biology, soft-matter physics and chemical and biomedical engineering. I advise graduate students in the departments of Chemical and Biological Engineering and Mathematics, and I am part of the Biomedical Engineering Program and a member of the Math Biology group. Our methodology involves numerical simulations and experiments. Computational work uses local clusters as well as the WestGrid. Much of the experimental work is done at the Laboratory for Complex and Non-Newtonian Fluid Flow.
