EEG-based sentiment & brain-state tracking (CNEL × Sony × LB3 dataset)
Pipeline that turns brain-wave recordings (EEG) into a small set of hidden time-series ‘states’ using a state-space model (Hierarchical Linear Dynamical System, HLDS), then evaluates those states for prediction and separability.

Zebrafish voltage imaging: event detection & interpretation
Pipeline for 2D voltage imaging videos that flags ‘events’ (fast, localized changes) using statistical detectors inspired by radar signal processing, producing maps and summaries for downstream analysis.

Plato’s Cave
System that extracts structured nodes (claims, evidence, limitations, etc.) from papers and scores them to support literature review and comparison across a collection.

Ergo — EMG/EEG biosignal acquisition + dynamical systems
Ergo integrates biosignal hardware, feature extraction, and simulation to test how control systems move between stable and unstable regimes under cooperating vs. competing subjects and fatigue.

Notes and photography
Why I care about state-space models for EEG
A quick note on using HLDS and related models to capture structure in EEG, instead of treating everything as i.i.d. features.
