About me

I am an Assistant Professor at the department of Chemical Sciences, IISER Berhampur. My broad research interest lies in chemistry and physics of inorganic materials (mostly oxides, chalcogenides and intermetallic compounds). I primarily work in the area of solid state chemistry with special focus on synthesis of new inorganic solids by exploration as well as by design. My group deals with synthesis of both single crystals and powder, utilizing various synthetic methodologies (sealed tube, hydrothermal, chemical vapor transport and flux crystal growth), their structural characterization (using single crystal and powder X-ray) and elucidating the electrical and magnetic properties. Another important focus of our research is Quantum Materials, particularly the Quantum Spin Liquid (QSL) phases and frustrated magnets. We aims to exploit the interplay of various degrees of freedom (spin, orbital, lattice and charge) in complex 4d and 5d transition metal oxides in a hope to unravel novel electrical and magnetic ground states.

Biography

Dr. Thakur was born in Madhya Pradesh, India in 1987. He graduated in Biotechnology from Jiwaji University, Gwalior in 2007 and later in 2009 obtained his master's degree in chemistry from Devi Ahilya university, Indore. He earned his PhD degree in 2016 from the Department of Chemistry, IIT Delhi under the supervision of Prof. Ashok K. Ganguli. His doctoral research was was focused on the magnetic and superconducting properties of new layered metal chalcogenide and pnictide compound. In Sept. 2016, he joined the Max Planck Institute for Chemical Physics of Solids, Dresden (with Prof. Martin Jansen and Prof. Claudia Felser) as a visiting scientist working in the field of crystal growth of novel complex 5d transition metal oxides. In Jan. 2021, he moved to Technical University Dresden (with Prof. Michael Ruck) for another postdoc on an independent research grant where he worked on the design and realization of new Quantum Materials based on 4d and 5d transition metal oxides until Dec 2023. In Jan 2024, he was appointed as an Assistant Professor in the department of chemical sciences, IISER Berhampur. His research broad research area is preparatory solid state chemistry.
