Chen Receives NSF and NIH Research Grants

Cheryl Kelly • DATE: August 29, 2012

Professor Danny Chen has received a three-year NSF award of $400,000 from the Algorithmic Foundations (AF) Program, Computing and Communication Foundations (CCF) of NSF, for a project "AF: Small: Applied and Theoretical Algorithm Problems in Computational Geometry." This project focuses on solving a set of applied geometric problems in medicine (e.g., disease diagnosis and treatment), biology, biomedical imaging, data mining, etc. The target applied problems include geometric covering, shaping, approximation, motion planning, clustering, and matching. The project also studies an array of theoretical problems, which are among the most fundamental tasks in computational geometry, on various optimal paths, visibility, Voronoi diagrams, etc.

Professor Chen has also received a four-year NIH grant of over a million dollars, for the project "Combined Multiscale Modeling and Experimental Study of Bacterial Swarming." This is a joint effort with Professors Mark Alber (PI, Concurrent Professor of CSE), Zhiliang Xu in the Department of Applied and Computational Mathematics and Statistics and Professor Joshua Shrout in the Department of Civil Engineering and Geological Sciences. This project will develop a multiscale modeling environment for studying bacterial motion and swarming. The research team will conduct predictive simulations to investigate complex bacterial interactions that potentially control swarming. Simulation study using such a multiscale modeling environment will lead to a deeper understanding of the universal or generic features of biological phenomena and simultaneous processes of bacterial swarming and interactions at different scales.
