Summary

Currently I am looking for a permanent position of a (junior) data scientist / statistician in Switzerland.
I would be delighted to hear from you if you have suchlike vacancies.

• Background in Machine Leaning, Time Series Analysis and Mathematical Finance.

• Experience in many applied projects in statistical consulting with advanced use of R, Python and Matlab.
• Applications in production engineering, geostatistics, finance, business decision making and web application development (R Shiny)

Education

2011 – 2014: ETH Zürich, MSc Statistics

Emphasis on advanced probability, time series analysis, multivariate statistics and machine learning.

MSc thesis “Parameter estimation for diffusion processe” (code in Matlab).
Supervisor: Prof. Dr. Hans-Rudolf Künsch
Used estimating functions approach in discretely sampled diffusions. Built a Monte-Carlo simulation, identified advantages and deficiencies of root-search algorithms and causes for asymptotic bias and inflated variance in the estimators.
___________________________________________________________

2008 – 2011: University of London, BSc Mathematical Economics and Finance
Lead college: London School of Economics (LSE)

Emphasis on quantitative finance, mathematical economics, econometrics, and optimization.
___________________________________________________________

2007 – 2011: Higher School of Economics (Moscow), BSc Mathematical Economics
(Double-degree programme with University of London)

BSc thesis “Methods of pricing of European type options with heavy-tailed distribution of the underlying”. Defended with excellence.
Found strong sensitivity of options with log-Levy alpha-stable distributed underlying (Hurst-Platen-Rachev model) to stability index & volatility, which may render it worse than Black-Scholes. Solved numerical integration instabilities.
