QCD Research Group at GW

Space-time is a lattice. Vacuum is a bowl of condensates.

Open positions


We study physics of the strong force, one of the four fundamental forces in nature (the other three are gravity, electromagnetism, and the weak force). The underlying theory of the strong force is called quantum chromodynamics (QCD) which governs the interactions of quarks and gluons, the fundamental building blocks of all matter. We try to answer questions like We perform calculations on supercomputers by approximating continuous space-time with a discrete 4-dimensional lattice (this is called lattice QCD). We develop our own software package called GWU-QCD that can run on a variety of computing architectures. We even build our own high-performance computer clusters using CPUs and graphics cards (GPUs) in collaboration with computer scientists. Our research is funded in part by U.S. Department of Energy and National Science Foundation. We maintain a wiki page (see link at the top-right corner). We can involve graduate as well as undergraduate students in research projects. If you are interested in doing research in our group, please contact Prof. Lee ( or Prof. Alexandru (

The Big Picture

We study the structure of matter on length scales of a femtometer (10-15m or 1 millionth nanometer), deep inside the heart of the atom:

Study of the very small is closely related to the study of the very big:

Outside Collaborations

At GW, we collaborate with colleagues from Statistics Department and SEAS. We are a founding member of IMPACT, a GW-wide institute for high-performance computing. We have also established local collaborations with the TQHN group at University of Maryland. Nationally, we are part of χQCD based at University of Kentucky, and USQCD. Internationally, we have collaborations with Prof. Wenger's group at University of Bern, Switzerland; Prof. Mathur's group at Tata Institute of India; and Prof. Leinweber's group at University of Adelaide, Australia.

Computing Resources

We have access to a variety of high-performance computers to carry out our research projects.
