Professor, Electrical and Computer Engineering

Research Interests

Much of the work in the Bio-Inspired Sensors and Optoelectronics Lab (BISOL) is driven by either a direct biological inspiration or by a desire to work with biology.  One project, for example, uses the eye as a model to build a highly sensitive light detector.  Current technology has not yet been able to duplicate the single photon performance of human rod cells and so by studying the way they work we were able to design and build a solid state, inorganic analogue that works better than any commercial system available of its kind.  We also work on building optical detectors designed for finding biologically important molecules like proteins, viruses and pharmaceuticals.  The detectors have nanoscale dimensions and are integrated directly onto the light source (tiny laser chips) with the hope of making a portable, matchbook-sized device that doctors can easily use to diagnose patients.  Life is one of the universe’s most complex systems and working towards its better understanding will help better our lives.
