Research in the Biomedical Optics Laboratory is concerned with the way light interacts with human tissue and how this interaction can be used for developing novel ways to image physiological processes and anatomical structures, for developing new laser-based optical diagnostic tools, and even for developing new ways to use light in the treatment of disease. The lab is a fully equipped, modern optics facility that houses vibration-isolated optical benches, numerous types of lasers and other light sources, state-of-the-art optoelectronic equipment, optical components, computers for conducting numerical simulations and for collecting and analyzing data, and an area for preparing and studying biological tissues and samples.

Research conducted in the Biosensors Laboratory focuses on the development of implantable wireless sensors for taking human physiological measurements, i.e., real-time stress and pressure monitoring. The lab supports rapid prototyping with equipment such as a 3-D scanner and printer. A circuit fabrication and testing station is used in the lab to fabricate sensor-detection devices. Computer-controllable measurement instruments such as multiple impedance/spectrum analyzers, lock-in amplifiers, power supplies, multimeters, and function generators are also available for characterizing sensors. The lab also features a functional machine shop with a computer-controlled milling machine and a polymer-casting facility.
The lab is staffed by a postdoctoral researcher, graduate students, and undergraduate students working on sensor-related research. The staff provides assistance with rapid prototyping and instrumentation to researchers from across the University community.

The facility’s activities include mammalian cell culture; tissue culture; bioreactor design and operation; biomaterial fabrication; and polymer synthesis.
Laboratory activities are focused on understanding how reduced interstitial flow, following lymphatic injuries, alters lymphatic regeneration and recovery of lymphatic function. The long-term goal of this research is to develop novel biomaterial and tissue engineering strategies for increasing interstitial flow, thereby improving lymphatic regeneration.
The lab is equipped for small-animal surgeries, tissue cryosectioning, fluorescence and brightfield microscopy, and live lymphatic imaging. Specialized instruments include an Olympus BX51 microscope and a Zeiss Apotome fluorescence microscope, both equipped with a high-resolution color digital camera; two Olympus stereo microscopes, available for small-animal surgeries with affixed DP71 digital color cameras; and a Near Infrared (NIR) imaging system, available for live imaging of lymphatic vessels in both rodents and humans.
