About
I am a materials scientist and electrochemist with more than six years of post-PhD research experience spanning the United States, South Korea, and India. My work sits at the intersection of nanomaterials synthesis and electrochemistry — designing carbon nanostructures, 2D transition-metal dichalcogenides, and metal-oxide ceramics, then putting them to work in batteries, electrocatalysts, sensors, and electromagnetic-shielding composites.
I currently work as a Postdoctoral Researcher (NSF-PREM) and Adjunct Instructor in the Department of Chemistry & Biochemistry at North Carolina Central University, where I develop 2D nanomaterials for electrocatalysis, corrosion protection, energy storage, photodetection, and electrochemical and gas sensing. My doctoral work at the Indian Institute of Science focused on multifunctional carbonaceous nanostructures for magnetic, optical, and catalytic applications.
Across 95 peer-reviewed publications, two granted patents, and two book chapters, my research consistently connects fundamental structure–property mechanisms to practical device performance — from fast-charging Li/Na-ion electrodes to absorption-dominated EMI shielding.
Alongside the lab work, I build open-source scientific software — the ElectroSim series of electrochemistry data-analysis apps (Python / Streamlit, developed in Visual Studio Code), with new tools actively in development.
Research Areas
My research program is organized around synthesizing functional nanomaterials and understanding the mechanisms that govern their electrochemical, magnetic, and optical behavior.
-
Energy Storage
Fast-charging Li/Na-ion electrode materials (LiFeBO3 cathodes, Fe3BO5 anodes), metal–air batteries, supercapacitors, and solid-state electrolytes.
-
Electrocatalysis
Carbon-supported alloy and single-site catalysts for HER, OER, ORR, and N2 reduction — including noble-metal-free electrodes for Zn–air batteries.
-
2D Nanomaterials
Transition-metal dichalcogenides and bismuth oxychalcogenides; substitutional doping for devices, photodetection, and electrochemical/fluorescent sensing.

LSV iR-Compensation Calculator
Public · GitHubA Streamlit web app that automates ohmic-drop (iR) compensation for linear-sweep voltammetry. It estimates uncompensated resistance from EIS data via Nyquist circle-fitting, then applies adjustable compensation factors to correct LSV curves — with batch processing, Excel/CSV import/export, and over-correction safeguards.
