Archbishop Mitty High School, Class of 2027 · LinkedIn

Hi! I'm Sudhanva, a senior at Archbishop Mitty High School with a strong passion for biology, particularly immunology and microbiology. I am currently involved in research to deepen my understanding and contribute meaningfully to science, most recently using machine learning to support autism diagnosis in the Wall Lab at Stanford.

Beyond research, I serve as captain of my school's Science Bowl and Quiz Bowl teams and captain of the debate team, where I have learned to think critically and communicate precisely. I am also the President of the Indigenous Justice Coalition, where I work to advocate for Indigenous well-being.

Overall, I bring a dynamic blend of scientific curiosity, leadership, and enthusiasm to everything I do. For an up-to-date CV, please email me at sudhubelur27@mittymonarch.com.

Vision-Language Model-Mediated Feature Extraction for Autism Classification from Play-Based Home Videos

Sudhanva Belur, Saimourya Surabhi, Aaron Kline, Kaitlyn Dunlap, Parnian Azizian, Mohammadmahdi Honarmand, Dennis Wall, PhD
First author · Stanford Pediatrics Internship Program (PIPS)

Summary

Diagnosing autism spectrum disorder (ASD) often takes long assessments, scarce specialists, and high costs, which delays early support for families. The Wall Lab had built machine learning models that diagnose ASD from home videos, but they depend on people watching each video and rating behaviors by hand. This project tested whether a vision-language model (Google's Gemini) could rate those same behaviors instead, making screening faster and cheaper.

What I did

  • Prepared a dataset of 560 play-based home videos from 19 children, checked its gender and diagnosis balance, and filled in missing values
  • Ran two of the lab's logistic regression classifiers (LR9, more conservative, and LR10, more aggressive) on features rated by Gemini and by human raters
  • Compared balanced accuracy, sensitivity, specificity, and AUC, and used SHAP plots to see which behaviors drove each model's predictions
  • Presented the results as a research poster

Key findings

  • With AI-rated features, both models performed about as well as with human ratings, and in some measures slightly better
  • Feature importance was very similar between the two rating sources, with only minor differences
  • Because AI ratings are far cheaper and faster, they could make video-based autism screening easier to reach
ModelRatingsBalanced Acc.AUC
LR9AI (Gemini)0.6910.737
LR9Human0.6380.707
LR10AI (Gemini)0.6840.755
LR10Human0.6630.754

Next steps

The study used only 19 children, so the next step is testing on a larger, more balanced dataset, trying other explainable models, and comparing against existing diagnostic tools such as CARS-2.

A Comparative Analysis of Language in Indigenous Federal Recognition Legislation

Researcher, as a leader of the Indigenous Justice Coalition

Summary

When Congress recognizes or restores a tribe, the exact wording of the bill shapes how much control that tribe has over its land, services, and government. Our team compared the language of eleven federal recognition and restoration acts to see how each provision affects tribal sovereignty. The goal was a reusable template and best practices for writing future recognition bills.

What I did

  • Analyzed eleven acts, including the Menominee Restoration Act, the Graton Rancheria Restoration Act, the Lumbee Fairness Act, and the Thomasina E. Jordan Indian Tribes of Virginia Federal Recognition Act
  • Split each bill into eight provision types, such as recognition, eligibility for federal services, membership rolls, governing bodies, trust land, and jurisdiction, then tracked how often key phrases appeared
  • Turned the findings into best-practice recommendations and a template for future legislation

Key findings

  • Land: Most bills (6 of 8) say the Secretary of the Interior "shall" take land into trust rather than "may." "Shall" removes agency discretion and makes land acquisition more predictable.
  • Recognition: Bills split evenly (5 to 5) between "extending" recognition, which creates new federal status, and "affirming" it, which acknowledges a tribe's continuous existence. The right choice depends on the tribe's prior status.
  • Services: Almost every bill (10 of 11) grants federal services without requiring a reservation, which widens access.
  • Governance: Bills either rebuild tribal government through an interim council or continue the tribe's existing government (5 to 4). We recommend continuity because it better respects tribes as sovereign nations.

Recommendations

The paper combined these findings with new provisions on healthcare, technical assistance, education, and cultural reparations to create a replicable outline for future bills. It also calls for more research on long-term outcomes and the barriers tribes still face in gaining recognition.

The Attenuating Effect of Dimethyl Sulfoxide and Sodium Hydroxide on the Degradation and Dissolution of PFAS in Water

Head Researcher

Summary

PFAS, often called "forever chemicals," are pollutants that don't break down naturally and build up in drinking water. This project tested how dimethyl sulfoxide (DMSO) and sodium hydroxide affect the degradation and dissolution of PFAS in water.

What I did

  • Led the project as head researcher, working about 3 hours a week for over 8 months
  • Handled DMSO and sodium hydroxide under supervision to test their effect on PFAS in water
  • Presented the results at the 2025 Synopsys Science Fair

Awards (2025 Synopsys Science Fair)
