Congratulations Chalapathi!

Congratulations to Chalapathi on completing his Ph.D. qualifying exam with flying colors! He joined our lab in the fall of 2018 and has been working on gynecologic tissue imaging and data analysis using our photothermal spectroscopic imaging system. We await to see outstanding achievements from him in the future.

Welcome!

Our lab works on inventing medical devices for cancer detection based on infrared optics. In these devices, we typically shine (laser) light on a certain region in the human body. A portion of this light comes back from tissue after scattering and absorption inside the tissue. This light that comes back is not random. In fact, the structure of cells and specific molecular composition of tissue is what determines what light comes back and at what wavelengths. By understanding how light scatters and absorbs, and by studying light-tissue interaction at different wavelengths, we can create a picture of what is going on inside the tissue. We can even see microscopic cellular structures and create high resolution images from which it is possible to determine if the tissue has a certain disease.
