About Me

I am a university teacher in stochastic analysis at the University of Edinburgh. I finished my PhD under the supervision of Professor Sandy Davie, and I work on pathwise approximation of stochastic differential equations using the coupling method.

I was the organiser of the working probability seminar of our group from January 2016 to May 2017. I also organised the PG colloquium in the maths department for the academic year 2014/15, and the joint PG colloquium on 1st May 2015.

Thanks to the generosity of the School of Mathematics, I was awarded the postgraduate essay prize 2014/15.

Research Interests

I have a broad interest in stochastic analysis, and in particular the theory and approximation of SDEs. During my first year Ph.D. I worked on the integrability and asymptotic stability with respect to a certain class of Lyapunov functions of modified ("tamed") Euler schemes for SDEs with non-globally Lipschitz coefficients. In my second year, I worked on estimating the minimal distances of the central limit theorem in the multi-dimensional case, and its application in controlling the computational cost of approximating multi-dimensional Lévy-driven SDEs.

My main focus now is on the Fourier approximation of multiple stochastic integrals, which leads to higher order approximations of SDE solutions.

I am also interested in the KMT method and some probabilistic applications of optimal transport.
