I (research portfolio: https://prognabanerjee.wixsite.com/prognaphasespace;) am a NST core-funded postdoctoral appointee at Argonne with strong interdisciplinary research background in experimental condensed matter physics, materials chemistry and electronics. I earned Ph.D. (Physics with Materials Chemistry) and M.S. (Strongly Correlated Condensed Matter) degrees from the University of Illinois at Urbana-Champaign, USA in Dec. 2018 & 2014, respectively. Before that, I completed M.Tech. (Solid State Technology) and M.Sc. (Physics) degrees from the Indian Institute of Technology, Kharagpur. Prior to starting my current position with the Argonne National Laboratory, I was an NSF MRSEC postdoc fellow at the University of Texas, Austin, USA (2020-2021) investigating light-matter interactions in bioinspired nanostructures; and an EBI-Shell ALS affiliated postdoc fellow at the Lawrence Berkeley National Laboratory, California, USA (2019) in battery science.
During my Ph.D. I used a template-based synthetic technique-‘cation exchange’ in chalcogenide nanocrystals obtained from quantum dots and established their unusual structural arrangement as the cause for exhibition of room-temperature superionicity and topological insulating properties. At UT, as a part of the NSF MRSEC IRG1 team I studied structure-optical property relationship in nanocrystal assemblies, such as superlattices & gels. I led the materials sub team comprising of researchers from UIUC, UT, and Northwestern on a DOD-funded multi-university research project (MURI) with my work focusing on understanding the mechanism of light interaction in leafhopper-insect derived nanostructures called brochosomes with inherently high antireflective properties ascribed to their buckyball-like structures. Presently at Argonne, I am the materials chemistry part of an interdisciplinary team looking to discover nanomaterials using Artificial Intelligence/Machine Learning assisted colloidal synthesis and post-synthetic cation exchange combinatorics using an autonomous liquid-handling platform, for the expansion of nanomaterials library into unconventional metastable phases and studying the emergence of various physicochemical properties in these systems. When not actively working at the lab benches or coding to improve data analysis & acquisition tools, I revel in mentoring students, in aiding to generate and channelize their enthusiasm towards understanding the cohesive story behind their project.
