Research Highlights

We employ University of Nebraska-Lincoln Supercomputing facility to carry out virtual experiments and explore behavior of matters under extreme conditions, e.g. under high temperature, high pressure, or in highly confined environments, in which real-world experiments may be impractical or inaccessible. As an example, we have revealed several new forms of ice and silicon, solely based on large-scale computer simulations. Below, we show a snapshot of 2-dimensional "Nebraska Ice"; and a snapshot of 1-dimensional single-walled hexagonal silicon nanotube.

Other research activities in my group include computer-aided molecular and materials design. Below, we show a golden "buckyball" Au₁₆ (for the New York Times). In short, the only limitation is our imagination!
