About the author of this website:
I am Rituraj Kalita (born 1968, Assam, e-mail: rkalita@rediffmail.com) living in Guwahati, Assam (India). Having arranged for a Master of Science in Chemistry (in 1992) from the Indian Institute of Technology, Kharagpur (W.B., India), I try to teach chemistry at Cotton College, Guwahati since 1993, and presently also dally with some theoretical chemistry research. Having a humanist bent of thought, I've attempted writing some essays on social and economic topics relating to Assam and the subcontinent, some poems, and has tried translating several Assamese poems and short stories to English. I am also a part-time computer and programming enthusiast (some other computer-related innovations being an MS-DOS batch-file based 'FORTRAN-77 HELPER' and dBase III Plus based 'College Routine- Maker', and a dBase III Plus based stock-management program for apparatus and chemicals at my workplace.) Here is a brief resume. To access my cell-phone (mobile) number, click here
