Dr. Mark Baskaran is a tenured full-time professor in the Department of Environmental Science and Geology at Wayne State University (Detroit, Michigan). He served as chair of the Department for 6 years (2018-2024). He received his Ph.D. in Physics from Physical Research Laboratory (PRL), a premier research institution in India. After his Ph.D., he spent two years at PRL as a postdoctoral fellow before he moved to the Institute of Marine Science at the University of Alaska (Fairbanks, Alaska). After a year, he joined Texas A&M University (Galveston, Texas) where he taught introductory Physics and Geology courses in the Department of Marine Science, while conducting research related to atmospheric fluxes of radionuclides, mobility of radionuclides in groundwater, scavenging and particle cycling in marine environment and dating of recent sediments and carbonates. After his 11 year career as a teacher and researcher in Texas, he joined Wayne State University where he became a tenured full professor in 2007. He teaches both introductory level courses in oceanography, meteorology, and physical geology as well as upper level courses including Environmental Fate and Transport of Pollutants, Isotopes: Applications in Geological and Environmental Sciences and Environmental Geochemistry.

Professor Mark Baskaran has published over 165 peer-reviewed articles (with over 10,594 Google Scholar cumulative citations, h-index 61, as of 18th September 2023), most of which are related to the applications of isotopes as tracers and chronometer in Earth sub-systems. He edited a two-volume Handbook entitled “Handbook of Environmental Isotope Geochemistry” with forty articles contributed by eminent scholars in the field in 2011, published by Springer. He also published a monograph on radon entitled "Radon: A Tracer for Geological, Geophysical and Geochemical Studies"--Springer 2016. He spent a semester as a Senior Fulbright Scholar at Ege University (Izmir, Turkey) in 2015. He was elected to the Academy of Scholars in 2021, a life-time appointment at Wayne State University. He has given invited and plenary talks/seminars at over sixty national/international conferences, workshops, universities and research institutions around the world. He served as an associate editor for two Elsevier journals, Journal of Environmental Radioactivity and Estuarine, Coastal and Shelf Science. 

Dr. Baskaran’s research work includes all subsystems of the Earth system. He has extensively collaborated with a large number of researchers from universities and institutions around the world. His work with marine systems (estuarine, coastal, shelf and open-ocean) on the investigations of particular organic carbon export, particle cycling and remineralization and colloidal thorium scavenging in the Arctic Ocean, Gulf of Mexico, North Atlantic and East Pacific were funded by several funding agencies in the U.S. including the National Science Foundation (NSF), National Oceanic and Atmospheric Administration (NOAA), and the Department of Energy (DOE). He has been funded by NSF as a part of the U.S. GEOTRACES group in four phases (Intercalibration, section studies in the North Atlantic, East Pacific and Western Arctic Ocean). He has served as a Chief Scientist in six major oceanographic expeditions in the Gulf of Mexico and Arctic Ocean.

He convened a national workshop entitled “Recent Changes in the Biogeochemistry of the Great Lakes System” in March 2013 at Wayne State University. He also had convened a number of sessions and meetings at both national and international conferences and workshops. He served as the inaugural Chair (2017-2021) of the Devendra Lal Memorial Medal Selection Committee, a union-level award at the American Geophysical Union. He also served as a member of the National Fulbright Screening Committee (2019-2021). Currently, he serves as a member in AGU's Honors and Recognition Committee.

Dr. Baskaran resides in Troy, Michigan with his wife, Rachel Baskaran. They have three grown-up children.
