Research interests
The current focus of our group is the application of probability theory at the interface between mathematical finance and power systems engineering. From 2013 to 2017 I have an EPSRC Early Career Research Fellowship titled Optimal prediction in local electricity markets focusing on the pricing and hedging of risk in electricity demand, for better balancing of future power systems.Group members and vacancies
Current group membersPostdoctoral: Our postdoctoral positions are currently filled.
PhD: Our group generally accepts one new PhD student per year. Please get in touch if you have good Mathematics degrees to Masters or MMath level with a strong component of probability or statistics courses.
Internships: These are short, focused projects, typically involving scientific programming and with a welldefined outcome, and can be offered at undergraduate, Masters and PhD level. Again please do not hesitate to get in touch if you are interested!
Industrial collaborations
Our group is delighted to be algorithm provider to the innovative startup company Upside, with whom we collaborate through PhD student Zehui Jin and postoctoral researcher Jhonny Gonzalez, funded by the Technology Strategy Board and EPSRC. We also provide algorithms to a startup electricity supplier.Consultancy services
We carry out a limited amount of consultancy activity in order to maximise the impact of our work. Our most recent project was the practical application of Real Options Analysis for Electricity North West Ltd.Publications
