Biophotonics is a multidisciplinary field where light-based technologies are utilized to reveal biological mechanisms, and diagnose several diseases along with finding their treatments. This course introduces the basics of biology and photonics, and provides the most relevant and important application from chemistry, biology, and medicine. For examples, it includes how to detect and identify new viruses (such as the Coronavirus) and how to measure neural activities in live mouse.
No specific prior knowledge is required to take the course; however, basic knowledge of optical physics will be useful.

Instructor bio

Prof. Basudev Lahiri

IIT Kharagpur
I am an Assistant Professor at the Department of Electronics and Electrical Communication Engineering, IIT Kharagpur, India. I have over fifteen years of experience in various nanofabrication techniques as applied to nanophotonics. I combine my expertise both as a designer of nanophotonics devices, and as a developer of new optical characterization techniques to produce novel Bio Nano Photonic technologies. Presently, I am developing new instrumentation methods that provide ultra-high resolution biochemical images, for the accurate diagnosis of viral and bacterial diseases.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
