In addition he continues to remain research active, with publications in, and several ongoing projects aimed at leading international journals.


Saeideh Dehghan-Nasiri

I came to STOR-i after completing an MSc Operational Research at Lancaster University. My PhD was supervised by Adam Letchford and focused on problems linked to optimising vehicle routing on real road networks. I completed my PhD project in 2014 with the quality of work being recognised by me being awarded the Kingsman Prize for 2015. After my PhD I then went to work for a local start up company.






Pedro Crespo del Granado

Prior to coming to Lancaster I had academic experiences at undergraduate and masters levels in the United States, France, Switzerland, Bolivia and China. I also worked briefly as data scientist at the IADB bank. In Lancaster, I was a STOR-i associate PhD student under the supervision of Stein Wallace and Zhan Pang. My PhD thesis entitled “The value of end user energy storage from intermittent renewables: an end-user perspective in Smart Grids” applied optimization modelling and stochastic programming methods to analyse various real-life case studies (energy systems of houses and communities).

After finishing my PhD in 2014 I have been a post-doc in the Energy Science Center at ETH Zurich. My project builds naturally on my PhD training as I am working in the area of integrated modelling of energy systems.


James Edwards

Before joining STOR-i I studied Mathematics at the Open University and an MSc in Management Science and Operational Research at Lancaster.

For PhD was on Bayesian sequential decision problems and the multi-armed bandit. These problems involve taking actions in sequence under uncertainty where outcomes resulting from actions gives information that can help in future decisions. This creates the need to trade-off exploration, to learn for the long term, against exploitation of current knowledge for good results in the short term. Part of this work was sponsored by Google and concerned the problem of choosing multiple website elements to display to a user.

After finishing I continued research in this area as a senior research associate at Lancaster on a project with a commercial partner on adaptive pricing.


Jamie Fairbrother

After joining STOR-i in October 2010, I undertook a PhD in the area in the are scenario generation, a problem concerned with the representation of uncertainty in decision-making problems for which I was jointly supervised by Amanda Turner and Stein Wallace. During my PhD I completed an internship at BT relating to the the calculation of maximum transmission powers of certain radio devices. Since completing my PhD in November 2015, I have taken up the position of research associate and am working on a problem in combinatorial optimization, motivated by a problem in telecommunications.


Tom Flowerdew

Before I started studying at STOR-i, I had completed a Masters degree in Mathematics and was working in the engineering sector. My PhD was industrially sponsored by ATASS Sports, and concerned how to optimally exploit profitable betting opportunities, which arise when betting on sports, and was co-supervised by Jon Tawn, Chris Kirkbride, and Kevin Glazebrook.

Since completing my PhD, I have been working as a data scientist for Featurespace, a small company based in Cambridge who specialises in building adaptive behavioural analytic models, which are used to catch fraud in financial services, insurance and gaming.


David Hofmeyr

My PhD, which I completed in 2015, was supervised by Nicos Pavlidis and Idris Eckley and looked at dimension reduction techniques for clustering and semi-supervised classification applications. After submitting my thesis I took up a position as a post-doctoral research associate within STOR-i, where I continue to work with Nicos Pavlidis. The work done in this position will look at extensions of the work done during my PhD to very high dimensional problems which arise in the modern context of "Big Data", and with particular attention to applications in bio-informatics.



Terry James

Before I started studying at STOR-i, I had completed an undergraduate Mathematics degree and was working in the civil service. My PhD was
co-supervised by Kevin Glazebrook in conjunction with Kyle Lin from the US Naval Postgraduate School. This research explored the task of identifying defensive surveillance policies that can mitigate the threats faced by adversaries in a public setting. For example, consider a surveillance resource responsible for a number of public areas, each of which is a potential target for an adversary. How should the resource be controlled given that the adversary can strike at any time in amongst any of the randomly evolving public crowds?

Since completing my PhD I have been undertaking PGCE training to become a mathematics teacher.


Rebecca Killick

I started my undergraduate degree (BSc) in Mathematics and Statistics at Lancaster University in 2004 and followed this with an MSc in Medical Statistics, again here at Lancaster. I then started a PhD entitled Novel methods for changepoint problems supervised by Idris Eckley (Lancaster) and Philip Jonathan (Shell) in October 2008. I completed my PhD in early 2012, then was a Senior Research Associate before taking up a lectureship in Statistics at Lancaster University in 2013. 





Karolina Krzemieniewska

Ye is now working for JBA Risk as Head of Catastrophe Modelling.






Natasa Margariti

I completed an MRes in Statistics and Operational Research at Lancaster University in September 2014. My dissertation was titled 'Interfacing Multivariate Extreme with Multivariate Statistics' and supervised by Professor Jonathan Tawn. I am currently working at Moodys Analytics in Edinburgh in the B&H division as a Modelling Operations Analyst. This involves calibrating stochastic models (e.g. interest rate models, equity models) as well as developing internal processes and quality assurance routines to help automate the production of high quality content services.


Jak Marshall

Before joining STOR-i, I completed my MSci in Mathematics and Statistics at Lancaster University with one year studying abroad at UC Berkeley. I then went on to complete by MRes and PhD at the STOR-i DTC. 

My PhD thesis, 'Models of Intelligence Operations' was created in partnership with the Naval Postgraduate School based in Monterey, California with Roberto Szetchman acting as co-supervisor. Kevin Glazebrook and Chris Kirkbride completed my supervisory team.

The project itself was concerned with modelling intelligence gathering processes in the military using Bayesian multi-armed bandit models. The formulation of a timed-limited and mission critical investigation as a stochastic dynamic programming problem allows for solutions whereby intelligence operatives can efficiently search for crucial information before it becomes outdated.

I now work as a data scientist in the games industry, and currently work for Sega Hardlight. 


Erin Mitchell

I began my studies at Lancaster University in 2006 when I studied for my undergraduate degree in Mathematics. I fell in love with both Lancaster and statistics, and decided to stay on to complete my PhD. My research focussed on the short term prediction of wind speeds, in particular using dynamic linear models for prediction, and logistic regression for in-depth analysis of rapid wind speed changes.

Since the completion of my thesis I have moved to Hertfordshire, and I now work in a games studio, Exient Ltd. We have recently released 'Angry Birds Go!' and will soon be releasing many more huge titles to the mobile market. I work as a data scientist/game analyst - I collect data from players to analyse the way in which they play and spend, and to optimise future improvements to our games. I get to be involved in the design, development and analysis of our games, with my work ranging from reporting on how our games are performing, to designing and balancing new levels.


Chris Nemeth

I completed my PhD at the STOR-i CDT in 2014 under the supervision of Professor Paul Fearnhead. My PhD was industrially sponsored by MBDA and focused on parameter estimation for nonlinear state-space models with applications to target tracking.

After completing my PhD I was a STOR-i Impact Fellow before beginning my current role as a lecturer in Statistical Learning in the Department of Mathematics and Statistics. I research problems related to Bayesian inference. In particular, Gaussian processes, Markov chain Monte Carlo algorithms and sequential Monte Carlo, with a focus on applications around intractable likelihood problems and big data scenarios.
