**About me**

Welcome to my homepage. I am an applied and computational mathematician and currently an Assistant Professor in the Department of Mathematical Sciences at the University of Massachusetts Lowell

I am working on several projects:

- Parallel fast integral equation solver for 3-D multi-layered media using the Fast Multipole Method (FMM) (Please visit this website to see what is the FMM and who is working on) and treecodes.
- Periodizing scheme with boundary integral equations for patterned multi-layer dielectric media (Scattering from 1000 layers shown on the right. Click the figure to see the high resolution version).
- Volume integral equations for Maxwell's equations.
- Modeling of ion channels using hybrid-solvation model (Poisson-Boltzmann equations).
- My advisor's (Prof. Wei Cai) book on computational methods is available on Amazon. Click the cover (I drew the graph) to see the table of contents, preface, and reviews
