Dr. Georgiana Ifrim

Funded Investigator

Machine Learning & Statistics

Dr. Georgiana Ifrim is an Associate Professor at the School of Computer Science, University College Dublin, Co-Lead of the SFI Centre for Research Training in Machine Learning (ML-Labs) and SFI Funded Investigator with the Insight Centre for Data Analytics and the VistaMilk SFI Research Centre. She is Director of Graduate Research at the School of Computer Science, UCD. Prior to this position, she held research fellow and postdoctoral positions with the Insight Centre for Data Analytics, University College Dublin, Ireland, Cork Constraint Computation Centre (4C), University College Cork, Ireland, and Bioinformatics Research Centre (BiRC), Aarhus University, Denmark. She holds a PhD and MSc from Max-Planck Institute for Informatics, Germany, and a BSc from University of Bucharest, Romania. Dr. Ifrim’s research focuses on developing scalable predictive models for machine learning and data mining applications. She has developed new methods for sequence learning, time series classification, text mining and real-time prediction for news and social streams. Dr. Ifrim has worked in application domains ranging from Web mining, news and social media, energy, biology and sports science. Her current research focuses on the design of efficient and interpretable learning models for sequences (e.g., DNA, time series), and on real-time prediction for streaming data (text mining for news and social media)
