Infrared Detectors are used in almost all applications from Astronomy, defense, product testing security etc, More recnelty IR techniques are  making a mark in biomedical advances too. We will describe a few detector ideas developed in our lab and address the development of a minimally invasive technique to screen for diseases using IR absorption.

    The incidence rates of cancers and other chronic diseases like inflammatory bowel diseases (IBDs) have been increasing in many regions and populations. Established diagnostic regimens for IBDs, such as colonoscopy have high sensitivity, but adherence rates of the eligible population for the disease screening is poor due to associated expenses, the risk of complications, time, and comfort issues. Similarly, there have been great strides made in developing new and innovative diagnostic/treatment regimens for several carcinogens. Thus, it is critical to develop a screening test for these diseases which is Affordable, Sensitive, Specific, User-friendly, Rapid, Equipment-free, and Deliverable (ASSURED). We discuss applicability of infrared spectral analysis of body fluids, accompanied with data analysis to evaluate disease induced alteration in the mechanism of constituent molecules. The results of our study show that serum samples can be used to detect the biochemical changes induced by cancers and IBDs. This potential technology can be further developed into a noninvasive, personalized diagnostic tool in which patient-to-patient differences in molecular signatures would allow the assessment of disease status and personalized drug management.

About the speaker: Dr. A. G. Unil Perera’s pioneering contributions to the infrared detector field, publishing more than 200 referred journal articles, (including more than 10 book chapters) and more than 10 US and International Patents, has bestowed him with high honors from the American Physical Society (Life Fellow- APS), Institute of Electrical and Electronics Engineers (Fellow – IEEE & IEEE Photonics Society) and Society of Photo-Instrumentation Engineers (Life Fellow SPIE). He is also an Editor of the IEEE Journal of Electron Device Society. He obtained a BS (Physics First class) from U. Colombo, Sri Lanka  in 1981, winning the Justin Samarasekara Award for the Most Outstanding Student of the Year. He came to US in 1982 and earned his PhD from University of Pittsburgh in 1987 and moved to Georgia State University where he won most of the University Awards including the Outstanding Faculty Scholarship Award, Outstanding Faculty Achievement Award, and the Alumni Distinguished Professor Award.  At present, he is a Regents’ Professor of Physics which is the highest Academic rank in the University System of Georgia. He is also recognized as an IEEE Photonics Society Distinguished Lecturer for 2020- 2022.

This event will be a hybrid (live/streamed) event. Due to the current state of the pandemic, there will be limited live seating available.
