Career Summary

I am a quantitative analyst and data scientist with more than ten years experience of model development and statistical analysis in the financial industry. As a Director with a large international bank I have been responsible for overseeing the modelling process all the way from sourcing data and developing a prototype, through the calibration and testing phase, and finally to documentation and presentation of results to internal and external stakeholders. My areas of expertise include Computational finance, Risk management, Bayesian statistics, Machine learning, Econometric and Time-series analysis. I have studied Mathematics, Physics and Engineering at the graduate level and have passed the CFA, PRM and CQF professional certification programs in risk management and finance. I program mainly in Python, R, Matlab, C++ and Julia. I am currently taking a break from banking to do research in Mathematical Statistics - during this period I do freelance work in statistics and machine learning to try my hands at new interesting problems. I very much enjoy work in Data Science.
