Heat Shields That Breathe by Design
Orion's Artemis I char loss came down to gas that could not escape. What if a heat shield's permeability were engineered, zone by zone, as carefully as its thickness?

Research and Development Engineer working at the intersection of multiphysics simulation, aerospace propulsion, biomedical engineering and intelligent manufacturing.
Introduction
Viraj Gajera is a Research and Development Engineer based in New York. His work sits where mechanical engineering meets computation: building physics-based and data-driven models that explain how complex systems behave, fail and can be made better.
His research spans an unusually wide arc, from fluid-structure interaction in the human brain's shunt systems, to combustion instability, thermal protection and retro-propulsive landing for reusable heavy-lift rockets, to physics-informed prognostics for additively manufactured rocket nozzles. Alongside that, he works on autonomous quality intelligence for manufacturing, closed-loop neuroadaptive wearables and self-healing polymer composites.
The common thread is a single question: how do we model a system well enough to predict what it will do next, and then design it to be safer, smarter and more resilient? newroboscience is where he shares that way of thinking, translating frontier research in robotics, aerospace and biotech into clear explainers and open ideas for others to build on.

Open concepts From the Ideas Lab
Factories That Detect, Decide and Heal
Combining autonomous quality inspection with self-healing materials could close the loop from defect to repair.
Self-Reporting Hardware for Reusable Rockets
Reusable boosters fly again and again. Their parts should be able to tell us how much life they have left.
