Biography

        Dr. Ananthanarayanan Krishnamoorthy is an Associate Professor (Research) in the Department of Chemistry, SRM Institute of Science and Technology, Chennai, India. He received his doctorate degree in materials chemistry and then started his independent research career in the year 2007 as a Research Scientist in NanoCore, National University of Singapore, starting work on development of novel mesoporous electrode materials for energy conversion and storage. From late 2008 till June 2016, he held various positions like Research Scientist, Senior Research Scientist and Group Head at Solar Energy Research Institute of Singapore (SERIS). He then joined SRM Institute of Science and Technology during July 2016 and his research interests are developing flexible solar cells for low power electronics and organic-inorganic hybrid solar cells. He is the PI of a DST-SERB-EMR sponsored research project and he is also recognized as a mentor of a research project in the National Post Doctoral Fellowship sponsored by the Science and Engineering Research Board (SERB), Department of Science and Technology (DST), India.
