About Roy
Biography
Dr. Sudipta Roy was born in Kolkata, West Bengal. After her early education in Chemistry (B.Sc. in Chemistry (Hons.) from University of Calcutta) and Biochemistry (M.Sc. in Biochemistry from Bangalore University), she obtained her Ph.D. in Organic Chemistry as a DAAD Scholar from the Institut für Organische Chemie, Universität Regensburg, Germany (2012, Thesis Title: “Development of novel methodologies for the syntheses of biologically relevant nitrogen-heterocycles”). Afterwards, she moved to the Institut für Organische und Biomolekulare Chemie, Georg-August-Universität Göttingen, Germany.
