Personal profile

Research interests

My research interests are mathematical and numerical modelling of fluid flow, with special focus on multiphase flows. I have a strong background in applied mathematics combined with advanced skills in programming including parallel computing techniques.

As a member of the Sir Harry Ricardo Laboratories within the Advanced Engineering Centre, my main area of expertise is multiphase flows mostly for applications to gasoline and diesel engines. Other subjects I am interested in and have contributed to are related to multiphase physics: focusing of particles in subsonic and supersonic flows, flows with shock waves; the effect of droplets on heat transfer in supersonic boundary layers; geomechanical effects in oil reservoirs. In my research, I extensively use and develop new tools based on applied mathematics, Computer-Aided Engineering and programming.

Approach to teaching

My teaching covers core engineering disciplines: mechanics of materials and fluid mechanics. Working at the intersection of these two fields benefits both my research and my teaching; it makes it possible to apply knowledge and skills from both subjects, thus providing a holistic approach when solving an engineering problem. I also find that this dual perception gives me a deeper understanding of physical phenomena.

My ongoing research activity equips me with exciting topics of current interest that I like to discuss with my students. I promote problem solving skills and creativity, while providing students with necessary guidance and feedback. When teaching, I try to involve students in a dialogue, encouraging active learning, independent and critical thinking. I find it rewarding to participate in my students’ progress, professional and personal development.

Scholarly biography

In 2012, I graduated from the Department of Mechanics and Mathematics at Lomonosov Moscow State University with a PhD degree in Physics and Mathematics. While in Moscow, I contributed to a number of research projects on particle migration and particle focusing.

As a researcher at the Schlumberger Moscow Research Center (2006-2009), I participated in the development of commercial software, which models flows through porous media (oil and gas). My projects were related to double porosity model and coupling geomechanics: stresses, porosity and permeability, together with fluid flow.

In 2013 I joined the Sir Harry Ricardo Laboratories at the University of Brighton as a Research Fellow. Most recently I was appointed as a Senior Lecturer at the School of Computing, Engineering and Mathematics.

Supervisory Interests

I am interested in supervising research students in mathematical and numerical modelling for multiphase flows, aerodynamics and mass and heat transfer.
