One of my friends was a student of Mr. Siddharth K. Rastogi. He mentored my cousin while he was working on some projects.
He has worked on topics related to Public Policy, Trade and WTO, Tourism, China, Sports Analytics, and Bird-watching. Mr. Rastogi needs students with excellent writing and editorial skills, specifically academic writing and with excellent statistical analysis.
You must also look up some other professors as well with probably a better record in research. The general perception is that such internships are meaningless and might be useful only if you are amongst the top 1%.
