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.

    Kolkata, India

    Research Intern
    Department of CSE, Jadavpur University
    • Boosted vehicular smoke detection accuracy by up to 12% mAP across 3 public datasets using a λ-attention transformer head on a YOLOv5 backbone.
    • Increased training coverage by 5× with a dual-level synthetic smoke generation pipeline to overcome limited real-world data.
  • 2020 - 2022

    Bengaluru, India

    Research Intern
    Department of Chemical Engineering, Indian Institute of Science
    • Achieved 97% R² for nanopore formation probability and 95% R² for formation time prediction by training a two-stage ML framework on 20,840 unique graphene nanopore structures.
    • Quantified the effect of 18 structural features on pore formation kinetics using SHAP-based feature importance, providing interpretable physical insights.
