About
Welcome to my personal website covering my research and blog posts

I am the Global Head of Quantitative Analytics at LGT Bank in Zurich, where I lead a global quant team and architect the systematic investment platform for portfolio construction. I advance quantitative portfolio management through research, technology, and team development to deliver data-driven, robust investment solutions aligned with LGT’s long-term perspective and pursuit of excellence for clients.
Named Risk Magazine’s Quant of the Year 2024, I bring over 20 years of experience spanning both the buy-side and sell-side across derivatives, systematic strategies, and multi-asset investing. This cross-domain career has defined my research signature: solving applied problems by connecting ideas across asset classes and disciplines. I hold a PhD in Mathematical Statistics from the University of Tartu, with over 1,200 citations and an H-index of 18, with research spanning portfolio optimization, stochastic volatility, systematic strategies, machine learning, and blockchain/DeFi.
My contributions include the ROSAA (Robust Optimization of Strategic and Active Asset Allocation) framework and the log-normal beta stochastic volatility model. I serve on the editorial board of The Journal of Computational Finance and co-develop open-source Python libraries for quantitative finance. Outside of finance, I am a dedicated Brazilian Jiu-Jitsu practitioner and purple belt holder, where the lessons from the mat – patience, adaptability, and problem-solving under pressure – carry over to my life.
