He received his MS degree from Moscow State University in 1998 and Ph.D. from the University of Pennsylvania (with Dawn Bonnell) in 2002.

Research Description

We explore applications of machine learning and artificial intelligence methods in materials synthesis, discovery, and optimization. The applications include physics discovery in energy and quantum materials, atomic fabrication via electron beams and scanning probe, and mesoscopic studies of electrochemical, ferroelectric, and transport phenomena via scanning probe microscopy of materials, combinatorial libraries, and operando devices. This effort is based on the development of hyper languages for description of the experiment and characterization workflows, workflow design and optimization, and implementation of automated and autonomous experiment in scanning transmission electron microscopy and scanning probes. This work is performed with multiple collaborating groups at UTK, ORNL, and academia and industry worldwide.
