i am a computer science student at lehigh university, with a minor in applied mathematics. i work on machine learning for scientific problems. right now that means interpretability of chemical language models. i am also interested in quantum computing, and in making technical opportunity more equitable. if you are working on an initiative, a project or a startup like that, don't just say hello. talk to me about books, politics, wellness, and whatever small thing you are doing to make an impact on the world.

research

mechanistic interpretability of chemical language models (april 2026 to present)
i train top-k sparse autoencoders on 1.7m polymer embeddings from a chemical language model (poly4mer / smi-ted), then use logistic regression and zero-ablation to test which learned features encode molar group information. first author, poly4mer-sae: a controllable polymer llm for understanding molar structures and beyond, in preparation.

  • first author, poly4mer-sae: a controllable polymer llm for understanding molar structures and beyond. in preparation.
  • diffusion models for atmospheric turbulence super-resolution (summer 2026)
    i benchmarked a vae, a cnn u-net, an adversarial neural operator, ddpm, and ddim on the johns hopkins turbulence database. the adversarial neural operator approaches state of the art with fewer training samples, and diffusion models outperform the rest.

    speckle analysis of actin dynamics at the lamellipodium (summer 2024)
    i built models to classify single-particle trajectories across 60+ data sheets, and presented at the lehigh research symposium.

    publications

    an approach for detection of atrial fibrillation using quantum sensor in magnetic induction tomography (mit) (2022)
    download

    abstract

    atrial fibrillation (af) is the most common sustained cardiac rhythm disorder characterized by rapid and irregular beating of the atrial chambers of the heart. the prevalence of af is expected to double in the next decades, creating the threat of a global medical challenge. causing more deaths in developed countries than in developing countries, the timely detection of af is still not achieved due to the lack of precise diagnostic and guiding tools, questioning the scientific and technological society of the 21st century. therefore, we identify a promising novel solution of a quantum sensor in mit as a precise diagnostic tool for the detection of atrial fibrillation. a quantum sensor is applied in the system as an excitation detection agent, designed mainly for biomedical applications. the feasibility of this method makes it a promising tool also for other areas such as neurology and oncology.

    low cost hot air balloon (2021)
    download

    abstract

    we developed a lesson-plan and bill of materials which teach students how to build a low-cost high-altitude balloon capable of reaching near-space. this project develops a new method of preparing for and solving the challenges of near space, performing near space experiments using a cost-effective payload tied to a hot air balloon, which requires high skills like problem solving, proper planning, deep analysis, tracking and recovery. hot air balloon payloads provide information on the atmosphere, the universe, the sun, and the near-earth and space environment.

    projects

    skillion capstone: facial and object recognition (2026)
    an end-to-end recognition system with yolo, facenet, and mtcnn, built with sponsors and shipped as a working mvp in one semester.

    alexa assistant for laboratory procedures (2023 to present)
    a voice app in python that guides scientists through materials science procedures and lab equipment. i lead the project at the nano human interface lab and mentor new lab programmers.

    veggies: connecting farmers with tech
    an android app that uses machine learning to ease farming work: timely crop disease detection, weather alerts, a marketplace for selling produce, and crop suggestions by season, location, and soil ph.

    writing

    welcome to my ted talk :-) i wrote a short review of meditations by marcus aurelius and hisila by hisila yami. if you feel the same about the books, or don't, let's have a short book talk. happy reading!
