I am a Postdoctoral fellow working with Prof. Oskar Painter in the Applied Physics Department at the California Institute of Technology. My current research interests lie in the integration of wavelength scale semiconductors lasers, intimate metal contacts, and optomechanics.

My graduate work consisted of several projects under the umbrella of microscale semiconductor lasers and cavities. Each project involved design and simulation, fabrication, testing, and instrumentation.

I began my graduate work by developing mid infrared photonic crystal resonant detectors (Dot-in-Well) and lasers (Quantum Cascade). Surface sensitive Quantum Cascade lasers were developed into sensors of analytes in the liquid phase. Work was carried out towards device integration with polymer microfluidic chips. My focus then shifted to studying surface-plasmon dielectric mode hybridization and lasing in sub-wavelength partially silver coated microdisk cavities. In parallel, light-matter interaction in the strong-coupling regime was investigated in semiconductor microdisk structures where one quantum dot exciton interacts with one optical mode.
