I am Dr. Nandan Ghorai, a Postdoctoral Researcher at the University of Pennsylvania. My work bridges spectroelectrochemistry, plasmonics, quantum materials, and ultrafast infrared spectroscopy to uncover interfacial charge‑transfer and energy‑conversion mechanisms at the nanoscale.

The University of Pennsylvania (Penn) is a member of the Ivy League, consistently ranked among the top universities worldwide (QS Ranking 11 in 2025). Penn is recognized for its excellence in research and teaching across disciplines, with the Department of Chemistry and the Vagelos Laboratory for Energy Science and Technology providing a dynamic environment for innovation in physical chemistry and materials science. Its status as a global leader in higher education fosters interdisciplinary collaboration, preparing researchers for impactful academic and scientific careers.

I investigate coupled electronic–vibrational dynamics and hot‑carrier processes in metal/semiconductor and quantum‑material heterostructures using ultrafast visible–NIR pump–probe and mid‑IR spectroscopies, often under operando electrochemical control. My current efforts focus on (i) hot‑electron and hot‑hole transfer in plasmonic/semiconductor systems, (ii) electrochemical charging of quantum materials and correlated oxides, and (iii) infrared spectroelectrochemistry platforms that resolve femtosecond–microsecond dynamics relevant to photocatalysis, solar energy conversion, and quantum photonics.
