Alex Smolyanitsky (Fed)

Materials Scientist

Research interests:

I use theory, particle-based simulations, and quantum-chemical calculations to perform interdisciplinary studies of nanoscale phenomena with a special focus on the properties of solid-solid/solid-liquid interfaces and the effects of confinement. My interests range from the frictional properties of two-dimensional materials to the design of nanoscale/biomimetic devices for molecular sensing, separation, and energy storage. 

If you are a postdoctoral candidate, we have openings that are immediately available to all US Citizens through the NRC Research Associateship Program (see below). If you have any questions, please email me.

Postdoctoral openings:
