Program

The Unit admits students for research leading to the Ph.D. degree. Newly admitted students are required to take courses within the Unit and in other departments of the Institute as a part of their training. Students are also required to give at least two seminars during their Ph.D. studies. The minimum qualification for admission to the Ph.D. program is a Masters degree in Chemistry, Physics, Materials Science or a related subject.  For those with M.Sc. in Chemistry, Physics or Mathematics must have been a part of their Undergraduate curriculum. Many students join the Unit through the institute’s Integrated Ph.D. program. The qualification for the Integrated Ph.D. pram is a Bachelor’s degree in Science. Detailed information for mode of entry to Ph.D. and Int. Ph.D. Programs of IISc can be obtained from:  http://www.iisc.ernet.in/admissions/

The Unit also provides opportunities for post-doctoral research. Announcements with regard to post-doctoral positions are posted on the SSCU website (http://sscu.iisc.ernet.in/) as and when they are available.

Apart from students joining the Unit through regular research programs of IISc, many students are selected to carry out research under specific projects as Project Assistant/Associate/Trainee (Qualification: Master’s degree in Chemistry, Physics, Materials Science). Announcements with regard to Project Assistantships are posted on the SSCU website (http://sscu.iisc.ernet.in/) as and when they are available.

The Unit also welcomes every year limited number of highly meritorious students for Summer Assistantships (Qualification: 1st/2nd Yr. Master’s degree, B.Tech./BE 7th semester), Master’s degree Project Work at the Unit.  Interested candidates may directly contact faculty member/s (http://sscu.iisc.ernet.in/prg/faculty/index.htm) matching their area of research interests.
