Detecting anomalies in the VAT network

Developing tools to identify abnormal data events (and fraudulent behaviour) in the VAT transactions network.

Forecasting with large macroeconomic and financial datasets

Improving the ability of widely used economic forecasting models to deal with volatile changes such as those caused by financial …

Poisson processes for identity systems and cyber security

Contributing to the analysis of event sequence data through a novel mechanistic modelling framework for marked spatiotemporal point …

Probabilistic fault detection and power forecasting in Wind parks

We apply modern statistical and ML methods for probabilistic fault detection and power forecasting using SCADA data from wind turbines.

Recovering Utilities from observational data

We consider the problem of inverse reinforcement learning in an economic environment where the agent is a consumer who maximises their …

Thales and Friends

I am a co-founder – together with the writer Apostolos Doxiadis and the school teacher and writer Tefcros Michaelides of the not-for-profit organisation Thales and Friends. For the very active Greek site see the Greek language version. Thales + Friends works to bridge the chasm between mathematics and other forms of cultural activity. To achieve its aims, Thales + Friends works to create opportunities for interdisciplinary research and communication, through lectures, discussions, publications, and reading groups. Some international activities include:

Some of my public lectures about probability and statistics (in Greek) are here:
