Beyond Research
Sankha is an avid reader who never discriminates between genres and gobbles up everything he can find close to his hand (he mostly prefers high fantasy and fiction though). He loves video games, especially RPGs (that may not always require his trusty PC and PS). Sankha has a tendency to go off the grid at least once a year, usually for high-altitude trekking. He also likes to write a lot, either in his mother tongue, Bengali or if the audience demands then, English. His literary works are mainly non-fiction, boring, post-editorial articles in newspapers, but at times, he also may feel fancy to venture into his imaginative (and romantic) side. Strongly believes in feminism, equity, and diversity. Oh, did you notice that Sankha has a knack for speaking about himself in the third person? Say, like Captain Terrence “Terry” Vincent Jeffords?
