I am currently a research associate at the Computer Laboratory of the University of Cambridge, working with Ted Briscoe on Automated Language Teaching and Assessment (ALTA). Previously, I was a postdoc in Cambridge English Language Assessment, working on self-assessment and tutoring systems for writing, and automated assessment models of learner text. Between 2009 and 2012, I was a Ph.D. student at the Computer Laboratory of the University of Cambridge, under the supervision of Professor Ted Briscoe. My Ph.D. on Automated Assessment of English-learner Writing was funded by Cambridge English within the framework of the English Profile Programme (EPP).
In 2009, I studied at the University of Cambridge, Computer Laboratory, where I gained the M.Phil. Degree in Computer Speech, Text & Internet Technology. The topic of my thesis was Grapheme-to-Phoneme Conversion for Greek, supervised by Professor Ted Briscoe. Prior to this, I studied at the Department of Informatics of the Athens University of Economics & Business, gaining a B.Sc. Degree in Computer Science in 2008. The topic of my thesis was Computer Aided Detection of early stage breast cancer from X-ray images, supervised by Professor Michalis Vazirgiannis.
