Students interested in working on a PhD project (to start in September 2020) in one of my areas of interest should contact me with informal enquires: firstname.lastname@example.org. See the School PhD applications website and MAC-MIGS website for available funding (we normally fully fund all students we accept) and for details regarding the formal application process (feel free to contact me to discuss research plan before submitting the application).
Current PhD Students
- William Hammersley, 2016 - present, he is working on McKean-Vlasov SDEs, SPDEs and related topics. He is funded by MIGSAA. This is part of work I do jointly with Lukasz Szpruch who is also William's main advisor.
- Bekzhan Kerimkulov, 2017 - present, he is working on PDEs on measure spaces, McKean-Vlasov SDEs and stochastic control. He is funded by MIGSAA. This is part of work I do jointly with Lukasz Szpruch.
Former PhD Students
- Neelima, 2015 - 2019, wrote a thesis on nonlinear SPDEs with non-standart growth and their regularity. She was funded by University of Edinburgh's Principal's Career Development Scholarship. She is currently an Assistant Professor at Ramjas College, University of Delhi.
