Alexander Lozovskiy

Specialization: Software Developer, Mathematician
I graduated from the Mechanics and Mathematics Department of Moscow State University in 2006 and was admitted to the graduate school of the Mathematics Department at the University of Pittsburgh in the US where I received my Ph.D. in 2010 in the field of numerical methods. Subsequently, I had worked at two universities - the University of Montpellier 2 in France and Texas A&M University in the US until 2016. I was involved in numerical modeling in various areas, such as collision mechanics, model reduction for shallow water equations, blood flow in arteries. Since 2017, I have been employed at an IT company in Texas. I am responsible for a C++ backend development of numerical methods used in the chemical processing and oil/gas industries. My recent projects in this area include direct solvers for sparse linear systems, constrained and unconstrained optimization methods, boundary value problems. I am proficient in C/C++ (both g++ and Visual Studio environments), Python, Fortran and on my way to learn more languages and frameworks. I specialize in algorithms in general and prioritize fundamental approach to problem solving. I made my own free online-course on the Finite Element method (in Russian).

Work experience

Software developer (currently remote)
03.2017 - 02.2022 |Bryan Research & Engineering, LLC, USA
C++, Visual Studio, TFS, Octave
Research and development in C++ of efficient numerical solvers for Windows; the tools are integrated into a chemical processing simulation software. I control the entire process from choosing the best strategy/algorithm to testing and modifying to detailed implementation. Completed and ongoing projects: linear sparse solvers, local unconstrained and constrained optimization, global optimization, boundary value problems, maintaining and improving the numerical methods part of the software. Training of other software developers in the above areas of numerical methods.
