An adjustable strengthening device and bio-mechanical dynamometer designed for in-orbit astronaut resistance training aboard NASA Artemis, with direct application in clinical hand and wrist rehabilitation. Currently licensed to an overseas partner for commercial therapeutic use.
Built for the realities of long-duration space travel, where months in microgravity compound into significant muscle and bone loss, PMARC reimagines how we exercise by making strength training compact, measurable, and engaging enough to sustain across an entire mission. An embedded electronic module captures force, repetition, and range-of-motion data in real time and syncs to a companion app that visualizes progress, gamifies sessions, and helps users actually keep showing up.
A research project identifying and validating high-performance additive-manufacturing infill architectures for compression. Built for spaceflight, where every gram and every Newton of load matters.
I built a custom AI to search the space of triply-periodic minimal-surface (TPMS) infills and surface the strongest, lightest candidates for a given load case. The architecture rendered above is one of the patterns the search discovered, not a stock gyroid: its level set is cos(x)·cos(y)·cos(z) − sin(x)·sin(y)·sin(z) = 0, a node-and-strut framework that diverges from the textbook surfaces it was inspired by. After printing each candidate I compression-tested it on the Instron press in Brown's Prince Laboratory, comparing its load curve in real time against standard rectilinear and concentric infills. The winning architectures beat the commodity baselines by up to 60% in compressive strength-to-mass. The tradeoff is print time: the smoother, more complex geometry takes meaningfully longer to lay down, so the gain in performance comes at a cost in throughput.
