Current Positions Prof. Dexuan Xie's research projects involve mathematical modeling and analysis, optimal control of PDEs, variational methods, numerical solution of linear and nonlinear partial differential equations, large-scale optimization, software package development, and large-scale biomolecular simulations. Their success will significantly advance the development of computational mathematics, high performance scientific computing, and computational biology.

Current Research Project

Prof. Dexuan Xie is currently working on a collaborative research project with Prof. L. Ridgway Scott at the University of Chicago under the support of NSF grants. This research project focuses on the study of nonlocal electrostatic continuum solvent modeling and related fast numerical solvers with applications to ion channel study, solvation free energy calculation, protein simulation, and rational drug design problems. One goal of the project is to understand the role of dielectric models in predicting the mechanism of ion channels (mainly sodium and calcium channels).

Previous Research Projects

Prof. Dexuan Xie have being worked on the following four projects since 2002:

  • Simulation of protein-membrane interactions by implicit solvent models.
      This project was supported by the National Science Foundation. The co-PI was Dr. Peter Butko, Professor of Biochemistry at the University of Southern Mississippi.
  • MSM Multiscale Modeling of the Heart in Cardiovascular.
      This project was supported by the National Institute of Biomedical Imaging and Bioengineering. The PI was Prof. Daniel A. Beard, the Biotechnology and Bioengineering Center at the Medical College of Wisconsin. Other co-PI included Dr. Nicolas Smith, the Bioengineering Institute at the University of Auckland, New Zealand.
  • Visualization of structure-activity relationships of chemical databases.
      This project was supported by a research award from the Graduate School Research Committee of UWM.
  • Electrostatic analysis of Cytochrome c by implicit solvent approach.
      The co-PI was Dr. Benjamin A. Feinberg, Professor of Chemistry at UWM.
