Research
Research Interests
- My work has focused on a variety of materials science challenges, including alloy design, metallic liquids and glasses, and properties of confined fluids in porous media. These areas have relied on close collaborations with experimentalists and theorists, often crossing traditional discipline boundaries. My background is particularly focused on the thermodynamics and statistical mechanics of materials.
