About

I am a dedicated researcher in energy conversion with a strong focus on electrochemistry-structure-activity
relationships, employing surface- and bulk-sensitive techniques such as in-situ/operando XPS (NAP-XPS) and XAS to
elucidate reaction pathways and catalyst stability. Expertise in designing advanced electrocatalysts and electrode
architectures using structurally and electronically tailored nanomaterials. Extensive experience in electrocatalyst
synthesis for OER, HER, ORR, AOR, and NRR, applied in water electrolyzers, PEMFCs, DAFCs, and ENRR systems.
Committed to developing scalable and sustainable energy technologies, with a strong emphasis on XPS- and XAS-based
mechanistic insights.
