Dr. Arkadii Arinstein was educated in Tomsk State University, receiving here the MSc degree (with honors) in Theoretical Physics in 1977. The PhD degree in Theoretical and Mathematical Physics he received from the Landau Institute for Theoretical Physics of the Russian Academy of Sciences in 1982. For many years A. Arinstein was occupied in the Semenov Institute for Chemical Physics of the Russian Academy of Sciences where he received DSc (habilitation) degree in 1995. In parallel A. Arinstein was teaching in Moscow State Technological University "STANKIN" where he got the Professor's rank (government certificate 1999) in Mathematical Department. Starting 2003 A. Arinstein is working in Israel, initially in Bar-Ilan university, and thereafter in Technion − Israel Institute of Technology as the Research-Professor. His research interests include statistical physics of polymers and disordered systems; non-linear and kinetic phenomena; etc. Last 15 years his studies are devoted, in general, to the physical problems in electrospinning of polymer nanofibers. The basic results of these researches are presented in his book "Electrospun Polymer Nanofibers". A. Arinstein was awarded a few honors, such as: the State grant for outstanding scientists of Russia (1995); the annual Vinogradov Prize awarded by the Vinogradov Society of Rheology (2019); the Fellow of International Association of Advanced Materials (2020); A. Arinstein is the member of Vinogradov Society of Rheology (Russia); of American Physical Society (USA); of IOP Institute of Physics (UK).
