Electromagnetic theory, thermodynamics and electronics at the Under Graduate level and General Condensed Matter and Advanced Condensed Matter I at the Post Graduate level.
I did my PhD under the guidance of Prof. Soumen Kumar Roy of the Department of Physics, Jadavpur University. Our work focussed on the experimental determination of elastic constants, dielectric anisotropy and rotational viscosity coefficients of liquid crystalline mixtures (both mesogenic-mesogenic as well as mesogenic-nonmesogenic mixtures) using electric field induced Freedericksz transition. We also studied the phase transitions of these mixtures and tried to theoretically explain some anomalous behaviour that we had observed using Landau theory. The title of my thesis was "Physical characterisation and phase transitions of some mesogenic-mesogenic and mesogenic-nonmesogenic mixtures" for which I was awarded the PhD degree from Jadavpur University in February, 2004. At present I have switched to mostly theoretical and computational work in the field of liquid crystals. I am currently working on various statistical mechanical models of liquid crystalline systems. I was the Principal Investigator (PI) of a major project entitled "Monte Carlo simulations on biaxial nematic liquid crystals" sanctioned by the CSIR. Prof. Soumen Kumar Roy, my erstwhile Ph. D. Guide, was the Co-PI of the project. Two servers were set up in a server room at the Physics Department of Lady Brabourne College using the financial grant that was received from CSIR. The Project has been completed successfully resulting in quite a few publications in reputed international journals. Two research scholars had enrolled under my guidance. One of them has submitted her thesis to the University of Calcutta in Janaury 2019 and subsequently has been awarded her Ph.D degree in November 2019. She is curently pursuing Post Doctoral Research work at NISER, Bhubaneshwar. My other research fellow is near completion of his work.
