It was Gohain who for the first time brought the ideas and methods of Anglo-American New Criticism to the study of Assamese/Indian literature in
Assamese. While studying in Cambridge, he had an eclectic radical ideology but later on, after his return to India, he became a Marxist. It was he who adapted the ideas of critics like György Lukács, Antonio Gramsci, and other critics into the nascent field of Assamese literary criticism. Some of his books in Assamese are
Sahityar Satya,
Sahitya Aru Chetana,
Biswayatan,
Asomiya Jatiya Jibanat Mahapurushiya Paramapara,
Assam: A Burning Question and several other significant and widely read books. He has also written 4 volumes of memoirs which are also relevant for their incorporation of social and historical content. He is a contributor to journals such as
Economic and Political Weekly,
Frontier, and occasional publications of institutions like Indian Institute of Advanced Studies (IIAS), Centre for English and Foreign Languages (CIEFL), Shillong. He also is a columnist for various regional and national newspapers. ==Political activism==
