Biography
2018 — current time. Senior Scientific Researcher, Department of Mathematical Methods for Quantum Technologies, Steklov Mathematical Institute of Russian Academy of Sciences (Moscow). In this period, a number of papers by O.V. Morzhin and Dr. Phys.-Math. Sc., RAS Prof. A.N. Pechen were published. Other co-authors: Cand. Phys.-Math. Sc. B.O. Volkov and V.N. Petruhanov. The scientific domain belongs to quantum optimal control and is focussed on study of open-loop control for certain classes of closed and open quantum systems via adapting the various mathematical methods of optimal control and finite-dimensional optimization. Along with A.N. Pechen, B.O. Volkov, and A.N. Petrukhanov, he is a co-author of the work «Landscapes of optimization for quantum gates and observables» which has been recognized by the Institute's Academic Council as one of the best works at Steklov Mathematical Institute of RAS in 2024.
O.V. Morzhin is in the members' list of the updated in November 2024 Editorial Board of the journal «Avtomatika i Telemekhanika» («Automation and Remote Control») — one of the leading scientific journals on the mathematical control theory, optimization methods. The journal is published since 1936. Now the journal is published under the RAS Department of Energy, Mechanics, Engineering and Management Processes at V.A. Trapeznikov Institute of Control Sciences of RAS (ICS RAS), co-founder of the journal is A.A. Kharkevich Institute for Information Transmission Problems of RAS.
2011 — 2017. Scientific work at ICS RAS (Moscow): a) in 2011 — 2015, in the 45th Lab. «Mathematical Methods for Study of Optimal Control Systems» under the leadership of the Honored Scientist of the Russian Federation V.F. Krotov; b) in 2015 — 2017, in the 38th Lab. «Control of Incomplete Data». He is a Senior Researcher since 2012.
2011. On Nov. 3, 2011, by the decision of a dissertation council at ICS RAS, O.V. Morzhin was awarded the degree of Candidate of Physical and Mathematical Sciences — Russian degree like to PhD in the relevant field. The Council's decision was accepted by the Ministry of Education and Science of the Russian Federation in the order dated March 22, 2012. The dissertation's title: «Methods for Nonlocal Improvement of Controls in Nonlinear Systems». Specialization: 05.13.01 -- «System Analysis, Control and Information Processing (in the Fields of Computer Science, Computer Engineering and Automation)». The dissertation proposes some new methods of sequential nonlocal improvements of controls in nonlinear optimal control problems considering differential and discrete systems. The approach uses, in particular, some special representations of the objective functionals' increments. Scientific adviser: Dr. Phys.-Math. Sc., Prof. A.S. Buldaev. Scientific consultant: Dr. Tech. Sc., Prof. A.I. Tyatyushkin.
2006 — 2011. Teaching and scientific work at the Institute of Mathematics and Computer Science,
Buryat State University (IMCS BSU, Ulan-Ude, Buryatia, Russia). In 2007, O.V. Morzhin became the winner in the nomination «The Best Assistant in the Natural Sciences» of the BSU competition «Best teacher».
2006. Graduated with with honors from IMCS BSU. Specialization: «Applied Mathematics and Informatics». In 2003 — 2004, O.V. Morzhin coursework was on asymptotic methods for ODEs under the guidance of RAS acad. A.M. Ilyin who worked for several years at IMCS BSU. The second coursework and diploma thesis were on iterative methods in optimal control, under the guidance of A.S. Buldaev. In 2001 — 2006, O.V. Morzhin was the headman of the students' group (05210). Being a student, in 2005 — 2006 he worked as a programmer at ISDCT of SB RAS.
2001. Graduated with a gold medal from the 37th Secondary School in Ulan-Ude (class with an in-depth study of mathematics). Mathematics teacher was G.M. Koneva being Excellent worker of national education (1991) who now is also a Honored Teacher of the Republic of Buryatia (2019).
