He holds M.S. and Ph.D degrees in Geology from the University of Delaware, and B.Sc. and M.Sc. Degrees in Geology from the University of Nagpur (India). Prior to his present position he served as Director of the Basin Research Institute of Louisiana State University, which is now the Basin Research Energy Section of the LGS. John joined the LGS in 1987 and subsequently held the positions of Assistant Professor-Research, Associate Professor-Research, Chief, Energy and Mineral Resources Section, and Director of Research before being appointed to his current position in 1997. He has previously served as an advanced geologist with Marathon Oil Company, as a senior exploration geologist with Geo Consultants International, and as geologist-in-charge of the Akula Clay mine with English India Clays Ltd.

John is a member of many professional associations and has served as president of the Louisiana Section of the American Institute of Professional Geologists (AIPG), the Energy Minerals Division of the American Association of Petroleum Geologists (AAPG), the Gulf Coast Association of Geological Societies (GCAGS), and the Baton Rouge Geological Society. He was elected as a Fellow of the Geological Society of America in 2004, has been a recipient of professional society awards, and is the author and/or co-author of numerous technical reports, book chapters, professional presentations and journal publications.

His fields of research specialization are petroleum geology, sedimentology, reservoir characterization, depositional environments and models of clastic sandstone reservoirs, geopressured-geothermal energy resources, coastal geomorphology and environmental geology.
