Developed novel optical techniques techniques for label-free detection of neural activity in tissue, and analysis techniques for studying computations in populations of retinal neurons.

• designed and built an ultra high-speed (5,000--20,000 fps acquisition rate, 1.2 GB/s data bandwidth), wide-field, low-noise (< 1.5 mrad RMS) interferometric microscope for label-free optical imaging of neural activity

• implemented a swept-source phase-resolved optical coherence tomography instrument for quantifying light-induced changes in retinal photoreceptors

• supervised graduate students: directed the development of a novel algorithm for processing time series recordings of retinal activity in MATLAB, supervised the implementation of signal-processing algorithms for retinal prosthetic applications, and guided the prototyping of a digital phase contrast microscope

• transformed a large monolithic Java application for visualizing and analyzing neural data streams into a distributed, multi-process, multi-threaded utility using ZeroMQ

Designed a novel neural prosthesis for restoration of sight to the blind. Responsibilities included:

• developing methods for automated analysis of large neural recording data (100+ GB) using supervised and unsupervised learning techniques such as dimensionality reduction, k-means and spectral clustering, dictionary learning and logistic regression classifiers

• designing and building near-the-eye display systems using LCD, DLP and holographic technologies to determine appropriate activation schemes for a retinal implant

• characterizing the visual percepts elicited by a retinal prosthesis in order to establish an expected baseline performance in the clinic

• modeling the electrical behavior of the implant using a finite element modeling package (COMSOL)

The results were published in 10+ peer-reviewed articles in journals such as Nat. Photonics, Nat. Medicine, Nat. Commun., J. Neural Engineering and others; they were also presented at 20+ international conferences.
