    Koushik Ghosh was born in Bolpur, West Bengal, India. After obtaining MSc. degree in chemistry from Visva-Bharati, he joined Prof. Akhila K. Sahoo’s group at the School of Chemistry, University of Hyderabad to pursue his doctoral study and worked in the area of C-H activation. After completing his doctoral research in 2018, he moved to Japan and started working as a postdoc researcher in Osaka University with Prof. Masahiro Miura. Next, he moved to ITbM Nagoya to pursue his second postdoc in Prof. Cathleen Crudden group.
