The most amazing...
...thing I've developed was a groundbreaking NLP algorithm to extract from social media the likeliest causes of major changes in the price of Bitcoin and Ethereum.
Work Experience
Doctoral Student (PhD Completed)
The Alan Turing Institute
- Earned a PhD at The Alan Turing Institute, the UK's national institute for data science and artificial intelligence.
- Created a new, nonparametric NLP algorithm (DDPWI) to extract from social media text the words associated with declining Bitcoin prices. Published in Royal Society Open Science.
- Applied neural networks in a new Word2vec-based topic modeling algorithm to detect which topics discussed on social media were associated with phasic shifts in Bitcoin prices. Presented at ACM SIGIR 2019.
- Showed the one-off effect of regulatory bans on Bitcoin and the recurring effects of rival innovations on the Ether price.
- Demonstrated how nonparametric correlation networks could be applied to explore the associations between the prices of different financial assets. This work has been cited 15 times.
Head of Data Science
ERS (A Lloyd's Syndicate and the UK's Largest Specialist Motor Insurer)
- Set up the data science team at the UK's largest specialist motor insurer with accountability at the board level.
- Enabled the fine-tuning of insurance premiums based on customized, specialized, nonparametric technologies rather than the standard linear models offered by Willis Towers Watson software.
- Pioneered the application of Random Forests, XGBoost, and GLM along with approaches to feature selection that included Random Forest techniques, including Boruta and statistical testing, to generate prediction models.
Data Scientist
Hitachi Consulting
- Introduced regression approaches (linear, lasso, ridge, elastic net, and logistic) to feature selection to improve the customer experience by transforming data into actionable insights.
- Identified potential root causes of sales revenue in a marketing project using machine learning feature selection approaches.
- Developed data science project templates used in machine learning and customer analytics projects.
Data Scientist
Model Citizens Ltd
- Managed customer data analysis identifying opportunities and threats for a retailer.
- Performed a data audit and analysis for an entertainment company.
- Pioneered the use of clustering algorithms to classify customers into different types.
Postgraduate Student
Grenoble École de Management
- Analyzed the financial and nonfinancial drivers of internet company valuations.
- Determined that financial statements could explain only about one-third of the variation in the price-to-sales ratio.
- Published in the journal, Bankers, Markets & Investors.
Internship
DN Capital
- Advised DN Capital on the threats and opportunities facing the European venture capital market.
- Provided guidance to DN Capital on how best to position itself to mitigate threats and take advantage of opportunities.
- Published a report that was awarded a First Class Degree by the University of Cambridge.
