Research track record
I do research in theoretical fluid dynamics, with strong emphasis on mathematics and a motivation of
seeking fundamental understanding of scientific problems that can eventually be beneficial to society. My
research strategy is to concentrate on a challenging problem, contribute my best, and move on. I can publish
a single paper on a topic and let the idea be taken over by other researchers, as for example it happened with
[20] long time ago or with [17] more recently. My main research, however, went in 15-20-year-long
overlapping cycles, the key publications for which are [16], [18], and [19]. Each cycle started with a
fundamental research and then shifted towards applications.
In the first cycle, I solved
[19] the long-standing problem of high-Re asymptotics of steady
separated flow, thus closing more than a century-long chapter in the history of classical fluid dynamics,
which started with the construction of small-Re asymptotics by George G. Stokes in 1851, continued with
the high-Re asymptotics for attached flows, which constitutes the famous boundary-layer theory, by Ludwig
Prandtl in 1904, and developed further by many researchers. With its central problem solved, the entire area
went out of the mainstream, but the theoretical ideas from the solution were then applied to study control of
flow separation using vortex cells.
The second cycle of my research is devoted to turbulence. Its starting problem was the origin of
streaks in near-wall turbulent flows. Going against the view dominant at the time, in [18] I provided
convincing arguments in favour of an emerging alternative paradigm and formulated a theoretical approach
capable of quantitative predictions. Considerable effort was required to disseminate the new ideas. My work
contributed to the acceptance of linearized methods in studies of developed turbulent flows. This constituted
a major change in the research direction in this area. Armed with these new fundamental ideas, my attention
was then shifted to turbulent skin friction drag reduction, which is a question of large practical importance,
and a great challenge. In [15] the dependence of drag reduction on the frequency and wave-number of in-
plane wall motion was considered. Streaks in a turbulent flow past an oscillating wall in the regime with
drag reduction were studied in [14]. These papers were the first-ever quantitative theoretical predictions for
these important features of turbulent flows with drag reduction, which previously could be obtained only in
experiment or direct numerical simulation. The current studies [6,12] within this second cycle are devoted to
the question of extrapolating the results of laboratory experiments and numerical calculations to the
conditions of aircraft flight, and to the question of practically-feasible methods of drag reduction. The
success of my second cycle of research is evidenced by the surge in personal invitations to give conference
talks and participate in advanced schools [Inv1-Inv6]. For me, however, this is also the evidence that it
might be time to move on once again.
In contrast to the previous cycles, the starting point of the third cycle of my research was not a
problem but a method: a breakthrough, made around 2000 in the works of Nesterov, Parrilo, and Lasserre, in
an area of mathematics seemingly unrelated to fluid dynamics. The idea
[16] of how to apply this
breakthrough to fluid-dynamics received a warm welcome, as it was evidenced by the personal invitations
for international events [Inv5,Inv7-Inv9] and by the award of a large EPSRC grant to the project “Sum-of-
squares approach to global stability and control of fluid flows”, which was coordinated by me and done by
teams of Imperial College and Oxford and Southampton universities. An invited paper [11] summarises the
ideas forming the basis for this current research cycle, which is quickly expanding in scope [1,5,7-9].
