This is my brain's cortical surface, reconstructed from a research MRI with FreeSurfer 7.4.1. It's an anatomical visualization, not a medical image or a diagnosis. The backdrop can show a live 3D model of the cortex, slices of the T1 MRI (brain only, resampled to 1.5 mm), or a still image. The Explore page adds deep structures and a movable MRI slice plane. Every cortical region is also listed as text on the About page.

Lectern Pro: AI rehearsal coaching

independent

A full-stack app for rehearsing talks, with real-time speech-pacing analytics, Q&A grounded in your own materials, and five coaching personas.

Why it matters
Practicing a talk alone gives no feedback. I built Lectern Pro to get some, and used it to rehearse a research poster presentation.
