Professor Mahajan received his Ph.D. from the University of British Columbia, Canada and then completed his post-doctoral training at Brookhaven National Laboratory. He holds a joint appointment between Stony Brook University and Brookhaven National Laboratory (BNL) and serves as Site Director, NSF Center for BioEnergy Research & Development (CBERD). He also serves as Associate Editor of the Journal of Renewable and Sustainable Energy. In 2011-12, Professor Mahajan served in-residence Jefferson Science Fellow in the newly created Bureau of Energy Resources (ENR) at the U.S. Department of State (DoS) in Washington, DC. At DoS, he worked on developing linkages between energy policy and technology in biofuels, natural gas, and ARPA-E-DOE/State, U.S.-India technical collaboration and represented DoS on the Committee on Energy Research and Technology (CERT) of the International Energy Agency (IEA).  In 2012, he served on Governor Cuomo's New York State (NYS) 2100 SUNY Committee on Energy. He continues to serve the U.S. Department of State, now affiliated with the Office of Intellectual Property Enforcement (IPE) in the Economic and Business Bureau (EB). Concurrently, he is working with the Turkana Basin Institute (TBI), a Leakey Family and Stony Brook university joint initiative, to help poverty reduction in Kenya. This is consistent with his vision to monitor energy policies and develop and implement energy-efficient technologies for human welfare by addressing energy, sustainability and climate change issues.

His research interests are in Energy issues that include a portfolio of projects on Biogas, Methane hydrates, Biomass and Natural gas conversion into liquid fuels using single-site or slurry-based catalysts. He has published over 230 papers and conference abstracts, delivered over 80 lectures, edited 6 special journal volumes and holds 11 patents. His recent approach is Low-Carbon Management (L-CEM) technologies. In this context, he has traveled as a: 1) Delegation member to universities in Beijing and Shanghai, China (2009), Visiting Researcher, Institute for Global Environmental Strategies (IGES), Hayama, Japan (2009) and Fulbright Specialist Scholar, Asian Institute of Technology (AIT), Thailand (2010). Since 2013, he is a Marie-Curie Exchange Researcher in a nine-country Biomass consortium funded jointly by the European Commission and the National Science Foundation. His recent notable projects are U.S.-China EcoPartnership between Stony Brook University and Tongji University, China, administered by the U.S. Department of State, to utilize landfill gas to transportation fuels. His focus is on developing power and fuel production technologies for incorporation in to village-level infrastructure to meet cooking (to reduce black carbon), transportation and power needs.

Nanoscale science and engineering continue to evolve from a scientific novelty to a broad-based technology with potential to transform medicine, productivity, sustainability, and the quality of life. In order to establish nanotechnology as a general-purpose technology with considerable economic impact, my research group mainly focuses on the following three research areas: (i) "Green" nanomanufacturing for manipulation of structures/functions of polymeric surfaces using carbon dioxide; (ii) Nanoscale control of methane hydrate formation as a future energy resource; (iii) Development of in-situ synchrotron x-ray scattering methodologies for structural characterization of hydrocarbon molecules during various chemical reaction processes. I am the spokesperson of the X27C beamline at the National Synchrotron Light Source (NSLS) where advanced seminal concepts of simultaneous small-angel x-ray scattering (SAXS) and wide-angle x-ray scattering (WAXS) methods are utilized to probe a wide range of bulk/solution structures at length scales ranging from angstroms to sub-microns. The major benefit of this facility to the materials community is that no extensive synchrotron experience and equipment preparation are required to carry out cutting-edge experiments.
