- Profile
-
Dr Triantafyllopoulos obtained a PhD from Warwick University (2002) after completing a BSc in Mathematics at Aristotle University of Thessaloniki (1996) and a MSc in Quality Management at Napier University of Edinburgh (1998). After a post-doctoral appointment at Bristol University (2001-2002) he took a lectureship at Newcastle University (2002-2004). He moved to Sheffield in February 2005. His research interests are in Bayesian time series and forecasting.
- Research interests
-
My research lies on Bayesian time series analysis. Application areas that I am interested include finance, bioinformatics, medicine, signal processing and quality control.
