Research interests

Searching for New Spatial Dimensions

If superstring theory is correct, there must exist as many as 7 additional spatial dimensions. Until recently, it was believed that these dimensions were too small to be detected, but many new models have been developed which suggest that these new dimensions could be as large as 0.1 mm. I am working with Ephraim Fischbach at Purdue University to devise ways of detecting small compact extra dimensions by testing Newtonian gravity as sub-millimeter separations.

Other Areas of Interest

I am also very interested in the following topics: Casimir forces, Quantum electrodynamics and effects of the quantum vacuum, quantum mechanics and quantum decoherence, and fundamental spacetime symmetries such as parity and time reversal.
