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, clinical science, biology and engineering 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.

 

Dr. Rajesh Kumar has worked past more than 10 years in Europe and USA (including NASA, JPL and MIT, Cambridge) in Biophotonics and, has leaded several cross-disciplinary R&D (sponsored) projects that sums more than 300 lakhs (INR). In IIT Ropar, he is working with wide range advanced microscopy imaging and spectroscopy techniques, which include label-free and non-invasive approaches for biomedical and healthcare applications.
