Research Statement

Our lab develops novel optical methods based on light scattering, interferometry, and microscopy, to image cells and tissues quantitatively and with nanoscale sensitivity. We apply our techniques to both basic science (e.g., cell dynamics, cell growth, intracellular transport, membrane fluctuations, tissue optics) and clinical applications (e.g., blood screening, cancer diagnosis). We are located in the Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana-Champaign. Prof. Gabriel Popescu is faculty in the Department of Electrical and Computer Engineering and affiliated faculty in Bioengineering; our group members are from Physics, Electrical, Mechanical, and Bioengineering.
