Research Summary: Venugopalan laboratory activities center around the study of photon transport, photo-induced thermal and mechanical transport processes, and their application to non-invasively image, characterize, and/or manipulate biological systems across spatial scales. Our group is highly multi-disciplinary with expertise spanning from applied mathematics, physics, and chemistry on one end to chemical engineering, biomedical engineering, and materials science on the other. Areas of current interest include:1. Mathematical and computational analysis of light transport in
cells and tissues with applications to thick tissue imaging and non-invasive measurement of tissue structure, composition, and function.
2. Development of highly-focused laser microbeam technologies for targeted cellular separation, injection, and mechanical stimulation.
3. Time-resolved microscopy, interferometry, and holography of laser-driven transport processes on nanosecond time-scales.
Research in the Venugopalan lab involves the integration of experiment, modeling, and computational approaches. Potential students are expected to display a high level of motivation, initiative, and interest in contributing to a dynamic, collaborative, inter-disciplinary research environment.
