Current research / employment

Biosensors based on surface plasmon resonance continue to attract attention as a simple and remarkably responsive label-free method for interrogating biomolecular interactions. Perhaps the most popular platforms guided by this principle are those which excite localized surface plasmons using thin metal films in prism coupled configurations. These platforms, despite their ubiquity and commercial success, are host to an amazing depth of phenomena which has to this date received little to no attention.

My research is focused on such phenomena - such as interference, scattering, and embedded speckle - and their possible avenues for advancing the ultimate detection limits of surface plasmon based biosensors.
