I am a Professor at the Department of Mathematics, University of York, having joined in 2005. I hold a PhD degree in the area of PDEs conferred by the Jagellonian University, Krakow, Poland in 1988.

Former roles include:

- Chair of Graduate School Committee (from 2012 to 2015)
- A Member of Graduate School Committee (from 2017)

Though fundamentally a Pure Mathematician, I do not like the distinction and I am interested in problems which come from applications and mathematical physics. Since the beginning of my PhD studies, my interests have been in Stochastic PDE's (SPDEs), turbulence and, in particular, in passive scalar equations.

I have a broad interest in maths which touches on geometric analysis and harmonic analysis. I am one of the world leaders in SPDEs theory and obtained fundamental results in the areas of geometric heat and wave equations, stochastic Navier-Stokes and Euler equations. I am well known for my work on the theory of stochastic integration, SPDEs in Banach spaces, and stochastic analysis on manifolds.

My results have been used by many mathematicians to develop the theory of nonlinear partial differential equations perturbed by noise and the analysis of infinite-dimensional manifolds, such as loop spaces, which are motivated in particular by quantum field theory, statistical physics and physics of ferromagnetic materials.

My research on stochastic geometric problems, especially those on the Landau-Lifshitz equations and Navier-Stokes equations are important to physicists and other non-mathematicians. In order to involve non-specialist audiences, I have co-organised many workshops and conferences, including:

- Harmonic analysis, stochastics and PDEs, 20-24 June 2022 at ICMS (Edinburgh)
- Stochastic Spin Systems: models, theory, simulation and real-world applications (Bielefeld 2017)
- The Indo-UK Workshop on Stochastic Partial Differential Equations and Application (Bangalore 2015)
- Nonlinear PDEs in Micromagnetism: Analysis, Numerics and Applications'' (Edinburgh 2013)

I was the main organiser of a six months long programme in 2010 on the Stochastic Partial Differential Equations at the Isaac Newton Institute; the others were K.D. Elworthy, M. Hairer, M. R{\"o}ckner, T. Souganidis and R. Tribe.
