Biomedical-Photonics Lab



The research in biomedical-photonics is one of the frontier areas of science and technology because, light is rapidly becoming an important diagnostic tool and a powerful weapon for modern physician. This is marked by the exponential growth of photonic-based technologies in the last decade applied to biology and medicine. Thus, biophotonics based tools is expected to play a key role in next-generation diagnostic, analytical, and therapeutic modalities of the 21st century.


“BioMedical-Photonics Lab” at IIT Ropar deals the highly interdisciplinary research work in collaboration with clinical professionals (e.g., surgeon, pathologist) that combines the expertise of physics, engineering and clinical science at International level to address the challenges of biology and medicine. Our goal is to develop novel photonics-based tools and, use them to understand the initiation and progression mechanism of disease as well as facilitate the early diagnosis, which can lead to an effective treatment of the disease.


Moreover, our research are exploring the potential of “photonics-based tools for food and agriculture” applications. For example, how to better guide management of fertilizer use in field crops that are economically important and relevant to the Indian agriculture system. The team of electrical and biological engineers from MIT, USA and IIT Ropar will work together to demonstrate rapid, specific crop diagnostics as decision support tools that are accessible to marginal farmers. In addition, we are developing an optical tool for rapid and label-free detection of agricultural pathogens in the farm field.
