Research interests of Prof. A. H. M. Ahmad include sedimentation and tectonic history of Proterozoic and Mesozoic sediments. I have keen interest in the understanding of tectonic and diagenetic evolution of Proterozoic and Mesozoic sediments. I teach sedimentary petrology, and Petroleum Geology at U.G and P.G level. I have supervised 15 doctoral thesis and 02 M.Phil. degree and at present supervising 05 doctoral thesis. I have published 116 research papers in peer reviewed journals of national and international repute. Some of important journals where my papers are published include Cretaceous Research, Sedimentary Geology, Bores, Journal of Asian Earth Sciences, Geochemical Journal, International Geological Review, Journal of the Geological Society of India, Geologica Acta, Geological Journal and Geologos. I have completed 07 research projects as Principal/Co Investigator and at present carrying out 01 research projects sponsored by UGC. I have been fellow and life member of many learned bodies and have been a member of IGCP-506, Treasurer Indian Association of Sedimentologists, and Member Indian Association of Sedimentologist.
