2025 to 2026

Team India, IYPT 2026

International Young Physicists' Tournament, ETH Zurich

One of five students from India selected, ranked fourth in the country after four qualifying rounds. Ran 80 independent experiments and derived graduate-level theory that predicted the results within 5%, then defended the work against teams from around the world. My report on the Magnetic Newton's Cradle received India's highest-ever individual report score. The team earned an honorable mention and its highest-ever rank.

Research and Internships

Two research internships, a GPT-2 study and open-source code

Jun to Jul 2026

Intern researcher

Department of Mechanical Engineering, Iowa State University, with Prof. Pranav Shrotriya

Applied advanced electrochemistry, training a CNN and a transformer on battery voltage decay to better predict battery lifespan and prevent premature disposal. The CNN on voltage-relaxation curves estimates the state of health of lithium-ion batteries with an RMSE of 2.4%. I also analyzed a multi-frequency EIS dataset and reviewed model-based and data-driven methods. Presented a poster at an NSF REU event.

Jun 2026 to present

Intern researcher

Vibrational Spectroscopy Lab, IIT Bombay, supervised by Prof. Dipanshu Bansal

Built a computational pipeline for quadrillionth-of-a-second laser diagnostics on crystals, for use in next-generation medical imaging and semiconductors. It is a PyMoDAQ pipeline for time-resolved second-harmonic-generation (TR-SHG) on ferroelectric thin films, with custom plugins I wrote to drive a Zelux camera, a Newport DL325 delay stage and an optical chopper. I am the only high school student in the lab.

May to Jul 2026

Mechanistic interpretability researcher

GPT-2, with input from Dr. Stephen Casper, MIT EECS

Used novel weighted graphs to show that semantics explain ideas in GPT-2 20% more accurately than context does, helping improve AI alignment. I wrote up the findings in a report of about 30 pages. The paper is under review at the TMLR journal and was accepted to the S.T. Yau High School Science Award.

Jun to Aug 2025

ML contributor

Smriti, an open-source photo and video management platform

Optimized image-recognition ML in C++ for offline devices in rural settings, reaching gaming-PC-level computing power on a $35 Raspberry Pi. Used ExecuTorch and the PyTorch C++ API to quantize EfficientNet models, and packaged the app in Docker for low-RAM devices.

Jun to Nov 2023

Intern

JetLearn, part-time

Designed a 15-lesson machine learning curriculum for children, using Scratch. Produced instructional videos that guide teachers on running each lesson, and helped train two teachers to deliver the curriculum.

Beyond the Lab

Student council, the school paper, the band and basketball

Elected President, Student Council

Elected by student vote as president for 2025 to 2026, leading 20 representatives across Treasury, Spirit, Culture, Sports and Outreach, and 15+ events a year. I launched AscendConnect, a student-alumni initiative with a 200-person networking event and online AMAs. I also started House merchandise, raising 40% of future budget.

Editor and co-head, The Ascent

The Ascent is the school newspaper. I recruited and mentored 15 writers across print, Substack and social media. I wrote 20+ articles and edited 150+ pieces, and launched Humans of Ascend, a series of interviews with members of the school community.

I set up the paper's website on SNO, and The Ascent is the only Indian newspaper in the SNO catalog.
