Alex Demkov is a professor of Physics at The University of Texas at Austin. He received his Ph.D. in theoretical physics in 1995 from Arizona State University (ASU). In 1995-1997, he was a postdoctoral researcher at ASU. In 1997-2005, he was a principal staff scientist in Motorola.s R&D organization providing theoretical support for the development of low- and high-k dielectric materials. In 2005, he joined the faculty of the Physics Department at the University of Texas at Austin. Prof. Demkov has published over 100 research papers and has been awarded seven U.S. patents. He has contributed to several books and edited one, entitled "Materials Fundamentals of Gate Dielectrics," and has also co-authored the 2005 edition of the International Technology Roadmap for Semiconductors (ITRS). In 2002-2004, he served as Associate Editor of the Journal of Vacuum Science and Technology B. He also served as Guest Editor for several issues of physica status solidi (b). He has organized numerous sessions and served on program committees of many national and international conferences. In 2009-2012 he served on the Executive Committee of the Forum of Industrial and Applied Physics of the American Physical Society (APS), and is currently serving on the APS Publication Oversight Committee. Demkov received the NSF CAREER award, 2011 IBM Faculty Award, and is a Fellow of the American Physical Society.

Research Interests
