Research results

Two questions I spent the past year on, and what the data said.

Advised by Prof. Sanchita Ghose, SFSUJan 2026 – present

66.36%

top-1 on EngageNet, the first audio-visual result on the benchmark

Audio-visual engagement detection

Does adding audio to a video-only model actually help it read student engagement?

Yes. The fused model beats four of six published video-only baselines. Along the way, fixing the inherited cross-attention lifted RAVDESS emotion accuracy from 66.67% to 71.25%, and swapping argmax for ordinal calibration gained +2.03 points at zero training cost.

7.93 / 10

on a 30-question gold suite across seven student personas, zero failures

JobSkill, a Self-RAG career advisor

Can retrieval stop an LLM from inventing course codes and job titles when it advises students?

Yes, if the critic is deterministic. Hybrid BM25 plus vector retrieval over 603 postings and 99 courses, with a citation-checking critic, held the score. Once retrieval was fixed, a 7B generator beat every larger model on quality per dollar.
