Senior Lecturer

Hello! I am Ioanna, a Senior Lecturer at Stockholm University! I live in Stockholm, have a great dog called Orion, and I am passionate about computer science, yoga, dance and extreme sports.

I am a member of the Data Science Research Group at the Department of Computer and Systems Sciences (DSV) of Stockholm University. I hold a Ph.D. in Computer Science from the University of Pisa, Italy, and a diploma in Electrical and Computer Engineering from the National Technical University of Athens, Greece.

My research interests lie in the fields of Data Science for Social Good, Nowcasting, and Forecasting, with the use of Big Data Analytics, Data Mining, and Machine Learning. Using Big Data deriving from everyday life as external proxies, it is possible to nowcast and forecast the evolution of phenomena whose study relies only on historical data or data that come with a significant lag. I work mainly on epidemics, healthcare, peace, and sentiment.

Learn more about my research by checking my publications. If you are interested in a thesis, please check my former topics and don’t hesitate to contact me.
