flwr-trees: Federated Learning for Tree Ensembles
An open-source Python library (on PyPI) that trains Random Forest, XGBoost and gradient-boosted tree models across clients using the Flower framework, behind a standard scikit-learn interface. Introduces histogram-based aggregation that cuts the first-round upload by 45–83% on benchmark datasets.
Contactless Vital-Sign Estimation from Video (rPPG)
Estimating heart rate, heart-rate variability and SpO2 from an ordinary webcam using remote photoplethysmography, as part of the “Walk for Life” project at the Institute of Liver and Biliary Sciences, New Delhi (2026–present). Public prototypes: SerenePulse and an in-browser HRV dashboard.
Brain-to-Brain Decoder: Dyadic EEG Representation Learning with CEBRA
An independent study that learns joint neural embeddings of two people in conversation from hyperscanning EEG. A hybrid CEBRA embedding decodes affective condition with 0.967 k-NN accuracy, while label- and temporal-shuffle controls fall to chance. Includes a reproducible pipeline and a plan for scaling to multiple dyads.
Few-Shot, Language-Agnostic Keyword Spotting (Smart India Hackathon 2024)
Winning team, Smart India Hackathon 2024 Grand Finale, for a problem statement set by the National Technical Research Organisation (NTRO) on detecting user-defined spoken keywords in any language from only a few examples.
LUFY: Retrieval-Augmented Understanding of Legal Documents
A legal-document assistant that turns an uploaded contract into a plain-language summary, a three-tier clause risk analysis and citation-grounded Q&A in English and 16 Indian languages. Uses hybrid dense + BM25 retrieval with reciprocal rank fusion and structure-aware chunking.
Schema Surgeon: An RL Environment for Database Schema Migration
A reinforcement-learning environment, built on OpenEnv, in which an agent migrates a messy NoSQL collection to a target JSON schema through rename, cast, flatten and delete actions, with a dense reward and reproducible tasks of increasing difficulty.

Positional Bias in Nested Defeasible Reasoning: Order Sensitivity and Unfaithful Intermediate Steps in Small Language Models
Manuscript in preparation, 2026
Do language models reason over nested defeasible premises in an order-invariant way, and do their correct answers rest on correct intermediate steps?

FIB-4 False Negatives in MASLD: Clinical Phenotypes and an Augmented Triage Model
APASL Single Topic Conference (STC) 2026, Kumamoto, Japan. Oral presentation FP5-2, 2026
Among MASLD patients classified as low-risk by FIB-4 (NHANES 2017–2020), 16.6% had significant (F2+) fibrosis, rising to 37.7% at BMI ≥ 40 kg/m². A supplementary model, FIB-4 Plus, outperformed the NAFLD Fibrosis Score (AUROC 0.837 vs. 0.749, DeLong p = 0.019). Oral presentation; APASL International Travel Award.
