Summary:

Our research work is focused on study of chemical, mechanical, electronic, and thermal properties of nano sized materials. At nano scales, entropic fluctuations become more prominent and materials behave differently. Our work is on capturing these effects in real devices and applications requires a range of modeling approaches, from hard theory (DFT and kinetics), to soft theory (continuum, statistical mechanics and molecular dynamics), and up through systems engineering approaches. There are various application to study such effect, including biomedical sensors (nanotube-based optical sensors)  and energy applications (CO2 to fuels, fuel cells, thermal catalysis). Following are our major projects:

  • Controlling selectivity of nanoscale interfaces with co-adsorbates and soft functionalizations
  • Machine-learning based approaches to accelerate materials screening
  • Bayesian methods for complex reaction mechanism reduction and elucidation

Nanotechnology is an interdisciplinary field focused on studying and manipulating ultraminiaturized structures, ones with at least one dimension 10,000 times smaller than the diameter of a human hair. This field has the potential to transform almost every aspect of our lives for the better – from enabling our cell phones and computers to run faster to generating our power more efficiently to making our tennis racquets and golf clubs lighter and more durable to making our medicines and drugs more efficacious. How can such small materials lead to such big advances in...
