Synopsis
My research group explores the application of new techniques in diffractive optics and micro/nano optics to the design of modern electro-optic and biomedical devices. This integration has led to many unique applications ranging from novel laser systems to specialized measurement and sensing instrumentation to extreme imaging architectures. Much of our work is highly interdisciplinary, drawing on various aspects of modern optics, signal processing, and device physics.

A primary interest in my group is microoptical system design, where the incorporation of MEMS components, micro/nano optics, and computational imaging techniques allows us to introduce unique functionality to optical systems. This includes hyperspectral imaging, adaptive imaging, and imaging with extreme form factors.

Exotic laser resonators have been of particular interest, where we are studying architectures for performing both coherent and incoherent methods of laser beam addition. We also study a variety of techniques for controlling and shaping laser modes, both by designing custom laser resonators and by applying optics external to the laser cavity.

A third research topic encompasses optical measurement and sensing technologies. We are studying applications of polarization and vector diffraction to measurement systems, and optimal design of biomedical instrumentation based on surface plasmon resonance detection.
