Instructor bio

Prof. Aloke Kumar

IISc Bangalore
Dr. Aloke Kumar received his Bachelors and Masters degrees from the Indian Institute of Technology, Kharagpur, India in 2005 and his Ph.D in Mechanical Engineering from Purdue University, West Lafayette, USA in 2010. His doctoral work is one of the founding works in the area of opto-electrofluidics. His research on opto-electric manipulation of matter in microfluidic systems has been recognized by the scientific community through several awards, including the prestigious DeKarman fellowship. After completing his doctoral work, Dr. Kumar joined the Oak Ridge National Laboratory (ORNL) as a Eugene Wigner Fellow. In this role, Dr. Kumar established a research program focused on understanding bacterial biofilms. After his post-doctoral work, Dr. Kumar joined University of Albertas Mechanical Engineering Department, where he was the Canada Research Chair in Microfluidics for Biological Systems. He recently moved to the Indian Institute of Science, where he is re-establishing his Soft Matter Lab with a focus on bacterial biofilms and polymeric flows. Dr. Kumars academic record boasts a constant pursuit of excellence. He has co-authored over 50 scientific manuscripts (38 peer-reviewed journal articles, 10 book chapters and 2 invited journal articles). He has published in reputed journals like Nanoscale, Lab-on-a-Chip, Langmuir and Physical Review Letters. Eight of his papers have also been journal cover articles (Soft Matter, Lab-on-a-Chip, Applied Physics Letters & Green Chemistry).

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).

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.


Average assignment score = 25% of average of best 6 assignments out of the total 8 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 IISc Bangalore.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.
