Research Experience
-
2024 - Present Ithaca, NY
PhD Researcher
Department of Systems Engineering, Cornell University
- Designed a BDE-conditioned transformer for generative molecular design, achieving distributional control over radical bond strengths with 81-94% validity and 84-92% novelty across BDE targets.
- Achieved up to 90% R² improvement in molecular property prediction by distilling SchNet and DimeNet++ into 2× smaller student GNNs across QM9, ESOL, and FreeSolv datasets.
-
2022 - 2024 Ithaca, NY
MS Researcher
Department of Chemical Engineering, Cornell University
- Trained DFT-accurate neural network potentials via active learning on HPC clusters for nanoconfined electrolytes, reaching force RMSEs ≤ 0.07 eV/Å and enabling fast MD simulations.
- Identified ion-specific interfacial behavior in confined electrolytes: K⁺ showed 3× stronger adsorption and 2× faster diffusion than Na⁺, trends absent in classical force fields.

2021 - 2022 Roorkee, India
Undergraduate Researcher
Department of Chemical Engineering, IIT Roorkee
- Developed a kinetic model for pine wood liquefaction, finding distillate formation nearly 2× faster than heavy residue, with secondary reactions negligible.
- Demonstrated that adding 20 wt% water more than doubled primary reaction rates, with guaiacol:water = 8:1 giving the highest overall conversion.
