Hello, and welcome to my personal website!

My name is Ioannis and I live in London. I am currently a Manager / Technical Modelling Specialist at the Financial Risk Management Division of the Bank of England.

About.

My role in the Quantitative Risk Analytics team involves providing technical expertise and developing statistical models for supporting the risk-management function of the Bank. Specifically, I’m working on designing simulation-based tools or macro-financial time-series forecasting models for measuring risks to the Bank’s balance sheet under stress-scenarios. I’m also leading on the implementation of a portfolio back-testing methodology for evaluating the statistical performance of the fixed-income asset-allocation strategies of the Bank.

Prior to that, I worked as a Senior Quant at the Risk Methodology team of the Financial Risk & Resilience Division, where I was primarily focused on building Expected Shortfall and Exposure-at-Default models for assessing risk across different asset-types and liquidity operations.

Outside of work, I enjoy sharing a bottle of wine with good friends, I like hiking and cycling, I love travelling and exploring new places, I am addicted to music and passionate about photography!
