Short CV - Research interests

Dimitris Valougeorgis graduated from the Department of Mechanical Engineering of the Aristotelion University of Thessaloniki (AUT) in 1980 and pursued graduate studies in the Virginia Polytechnic Institute and State University (VPI&SU), where he was awarded the degrees of M.S. and Ph.D. in Mechanical Engineering in 1982 and 1985 respectively.

During his graduate studies at VPI&SU he worked as a graduate research assistant in the areas of experimental combustion (1981-82) and computational rarefied gas dynamics (1982-85). From the summer of 1985 until the fall of 1987 he joined the Department of Mathematics of VPI&SU as a Visiting Assistant Professor, having in parallel a research appointment at the Center for Transport Theory and Mathematical Physics. After fulfilling his military duties in the Greek army he worked from 1989 until 1998, as a senior engineer in Hellenic Petroleum in the Industrial Complex of Thessaloniki. From 1988 until 1992 he also had a half time appointment, as a scientist specialist, at the Department of Mechanical Engineering of the Aristotelion University of Thessaloniki.

Since September 1998 he has been at the Department of Mechanical Engineering of the University of Thessaly (UTH), in Volos, Greece. He currently is Professor of Mesoscale Methods in Flows and Transport Phenomena and member of the Laboratory of Physical and Chemical Processes.

His recent research interests are in the areas of computational transport and kinetic theory of gases, rarefied gas dynamics, integral-differential equations (Boltzmann equation and kinetic models) and the Lattice Boltzmann method with applications in micro-fluidics, vacuum gas dynamics, fusion technology, high altitude aeronautics, magnetohydrodynamics, fluid structure interaction (sloshing) and gas pipe networks.

He is the author of about 70 scientific papers in journals and 100 conference papers and serves as a reviewer for many scientific journals in the areas of fluid mechanics and transport phenomena. He is in the Editorial Board of VACUUM. Also, he is in the Scientific Committees of several international conferences including the biannual European Conference in Microfluifdics and the European Conference of Non-Equilibrium Gas Flows. He has taught at VPI&SU, ΑUT and UTH undergraduate and graduate courses in applied mathematics, computational methods, CFD, heat tranfer and kinetic theory.

He is a Member of the Technical Chamber of Greece (TEE), the Greek Association of Computational Mechanics (GRACM) and ex-member of the American Society of Mechanical Engineers (ASME), the American Mathematical Society (AMS) and the Society of Industrial and Applied Mathematics (SIAM).
