About

Dr. Ratnasekhar CH is heading a research group on Systems Metabolomics at CSIR, India and Visiting fellow at Queen's University Belfast, United Kingdom, and is an expert in metabolomics. Having a background in chemistry, he moved into metabolomics for his PhD, which he received from CSIR, in 2014. During his four years postdoctoral training at University of Cambridge, University College London, and as a visiting scientist at The Francis Crick institute, London, UK, he found his passion in metabolomics, metabolic flux and was involved in the analysis of mass-spectrometry based metabolomics studies for investigating the cellular metabolism. Later, in 2019, he moved to School of Biological Sciences, Queen's University Belfast, UK for studying metabolic fingerprinting. In 2020, he started his research group at CSIR with the goal to understand the role of metabolism in complex model organisms including animal models and plants for investigating various diseases. To address these questions, his group rely on metabolome-wide association analysis using high resolution Orbitrap LC-MS and GC-MS and biochemicals assays.
