About Me

I am a Saint Lucian mathematician, CariScholar mentor, and Machine Learning Scientist (KTP Associate) with Kingston University London / Instinet Europe Ltd. My goal is to have an intellectually satisfying career that draws on my background in information technology and mathematics. Around the time of my undergraduate studies, I planned on becoming an information security professional, even applying for (and being accepting into) relevant postgraduate courses. Then, after discovering the Factor Analysis of Information Risk (FAIR) framework in 2011, I decided to shift my focus towards understanding the quantitative aspects of risk management, and how to make "optimal" decisions under uncertainty. This prompted me to study mathematical finance, stochastic control and game theory as a postgraduate student at the University of Manchester, topics that I have continued studying to this day.

My Experiences

After finishing my BSc and before commencing my MSc studies, I spent some time working as a web application developer and web site designer, gaining experience with software such as Apache HTTP server, PHP, phpMyAdmin, mySQL, mySQL WorkBench, jQuery, Yii and Wordpress.

Tempus Energy (formerly Alectrona Grid Services) was an industrial partner on my PhD project from September 2012 to September 2015. During this time I developed algorithm prototypes for automated demand-side management and predictive energy trading. I also assisted in making these prototypes production-ready and integrating them into a predictive energy trading platform.

Currently, I am a Machine Learning Scientist (KTP Associate) working on the development and deployment of innovative machine learning techniques for trading execution performance and monitoring. Prior to this, I was a Postdoctoral Researcher in Mathematics:

• From December 2018 to November 2019, I researched applications of risk-averse stochastic control to energy systems for the EPSRC grant EP/P002625/1 entitled "Markov chain optimisation for energy systems".
• From May 2016 to December 2018, I researched applications of stochastic control, microeconomics and game theory to power systems markets for the EPSRC grant EP/N013492/1 entitled "Nash equilibria for load balancing in networked power systems".
• From late November 2015 to May 2016, I worked on optimal stopping and optimal singular stochastic control problems for the research project “Optimal prediction in local electricity markets” (grant EP/K00557X/2).
