Understand. Design. Integrate.
VDLab investigates phenomena that span scales, turns that understanding into virtual models for materials, processes, and equipment, and connects those models to experiments and physical manufacturing through AI. Semiconductor manufacturing is our primary proving ground, while functional materials broaden the design space.
Multiscale Computational Science
Many engineering systems are governed by phenomena that cross length, time, and physical domains. We develop first-principles, atomistic, mesoscale, feature-scale, and continuum models, then connect them with physics-based and data-driven scale bridging. The result is not a collection of isolated simulations but a predictive description that carries mechanisms and uncertainty across scales.
More detail →Virtual Design of Materials, Processes & Equipment
We turn computational understanding into design variables and decisions. Our work spans semiconductor surfaces and interfaces, etching and deposition, film growth, reactor transport, and equipment conditions, with AI and optimization used to explore spaces that are too large for trial and error. The same methodology extends to broader functional materials.
More detail →Advanced Manufacturing AI
Advanced Manufacturing AI begins when virtual models and physical systems share information. We combine simulation, experimental databases, in-situ sensing, and reduced-order models in digital twins that can estimate hidden process states, explain predictions, and support optimization and control. Physical AI and agentic systems are the path toward closing this loop from observation to action.
