About Me

Abir Goswami was born and raised in West Bengal, India in 1992. There, he completed his undergraduate education in 2012 at University of Calcutta. After completing his master degree in Chemistry from the Indian Institute of Technology Guwahati (IITG) in 2014, he joined as a PhD (Organic Chemistry) at the University of Siegen (Germany) under the supervision of Prof. Dr. Michael Schmittel. During PhD training, his research interest was to study networked multicomponent molecular machines and autonomously controlled information systems. He has expertise in catalytic off-equilibrium molecular machinesIn 2020, he joined the Emergent Soft Matter Function research group at Riken as a postdoc under the supervision of Prof. Takuzo Aida. He is currently utilizing the nano-mechanical motion of monomer in supramolecular materials to get macroscopic functions, like in various biological systems. He is working on small fluorinated drug carriers to increase blood–brain barrier permeability that could solve the long-standing issue in pharmaceutical industry. Also, one of his project is to understand the dynamic bond braking/making to realize next generation supramolecular adhesive materials. In 2021, Dr. Goswami was awarded the JSPS postdoctoral fellowship.
