Physics of Biological Systems

By Prof. Mithun Mitra | IIT Bombay

Learners enrolled: 599

The application of physical principles to biological systems is an exciting and rapidly evolving feld of research. Methods of equilibrium and non-equilibrium statistical physics, stochastic processes, non-linear dynamics and polymer physics, among others have helped understand the guiding principles of a variety of biological processes. In this course,we will attempt to provide an introduction to the physics of biological systems using theoretical tools, with examples from diverse areas of biology such as pattern formation, low Reynolds number fows, cytoskeleton and motors and transport in cells, gene expression and chromatin organisation, among others.

Instructor bio

Prof. Mithun Mitra

IIT Bombay

I am a theoretical physicist with a training in statistical mechanics and soft condensed matter physics. My research focuses on understanding the physics of living systems, using both theoretical and simulation methods. In particular, some of the topics I am interested in include transport inside cells, the packaging of chromosomes in nuclei, and the physical principles underlying morphogenesis and growth of embryos.

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).
Date and Time of Exams: 29 April 2023 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Bombay. It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
