I have recently finished my PhD in Statistical Science where I studied at University College London (UCL) and a member of the Financial Computing CDT. I also have an MRes in Computer Science and an MPhys in Theoretical Physics from the University of Manchester.
I run a dashboard for crypto liquidity: https://cryptoliquiditymetrics.com/
I’m an open source contributor with multiple projects ongoing: dirichletprocess, HawkesProcesses.jl, AlphaVantage.jl, CoinbsePro.jl, AlpacaMarkets.jl.
I’ve written guest posts for QuestDB:
- High frequency finance with Julia and QuestDB
- A tour of high-frequency finance via the Julia language and QuestDB

My Day Job Now
I’m currently an electronic trading quant working on both principal and algo execution. I build models, analyse data and construct algorithms to try and get the best prices in the market with the lowest impact.
I was a quant at BestX and spent the day researching financial markets with a focus on transaction cost analysis (TCA). This involved cleaning data, making graphs and trying to come up with some (hopefully) interesting insights about the world of FX, fixed income and equity trading.
Examples of my work can be found in the trade press:
- FX Markets Remained Orderly During Recent Interventions
- To Cross or Not to Cross
- Choppy markets revive quest for RFQs magic number
- Volatile FX markets reveal pitfalls of RFQ
- Price limits in FX algos: fill your boots
- BestX RFQ Par Introduces a New Way to Look at Hit Ratios
- How Long Should TWAP algos run?
Some of which are behind a paywall.
Outside the Day Job
I also have a keen interest in sports modelling and how statistics can be used in professional sports and gambling, I enjoy a good film, watching a boxset too quickly and a bit of a foodie. Here I am enjoying some delicious Korean BBQ.
My blog is also aggregated on https://www.r-bloggers.com/ and https://www.juliabloggers.com/.
More Extreme Moves in a Downtrending Market?
I’m exploring whether there are more extreme moves in the equity market when we are in a downtrend. I think anecdotally we all notice these big red numbers when the market has been grinding lower over a period as it is the classic loss aversion of human psychology. This is loosely related to my Ph.D. in point processes and also a blog post from last year when I investigated trend following - Trend Following with ETFs. I’m going to take two approaches, a simple binomial model and a Hawkes process. For the data, we will be pulling the daily data from Alpaca Markets using my AlpacaMarkets.jl package.
