• One- and two-loop radiative corrections to high-energy cross sections in the standard model and its supersymmetric extensions.
• Software for generating Feynman diagrams and amplitudes in quantum field theories.
• Computer simulation of the structure and dynamics of complex systems and networks.

I am interested in gauge theories of elementary particles and their interactions, especially the SU(2)XU(1) theory of electroweak interactions and the quantum chromodynamic theory of strong interactions. I work on predictiong cross sections for high-energy collision reactions currently being studies by experimenters at the Fermilab Tevatron Collider, and planned for study at future high-energy physics facilities, such as the Large Hadron Collider at CERN. I am also interested in computational physics. I develop computer algebra algorithms and programs for performing Feynman diagram calculations in high-energy physics. I am interested in computer simulation methods and high-performance computing, and in teaching courses in these areas.
