I am now at HITS, Germany

Research

• I am fascinated by language, particularly by the link between our thoughts and the linguistic expressions that convey them. Most of my research is in semantic relation analysis, trying to find connections between concepts that surface in language in various syntactic forms. Much of my work these days involves dependency relations and using them for various tasks. I am interesting also in lexical semantics, and the way it arrises from contexts. I have worked also with the language of electronic negotiations. Part of the research topic is identifying behavioural patterns from the messages exchanged during an interaction.

People I work with:

• Stan Szpakowicz, my supervisor
• Ken Barker
• Elizabeth Scarlett
• Terry Copeck
• Mario Jarmasz
• Marina Sokolova

If you are thinking about graduate studies, consider these:

• Did you choose the right supervisor?
• You will eventually have to write a dissertation...
• ... possibly in English ...
• ... and for that you need to cheer yourself up sometimes, so here is some humour

Teaching - I usually teach Prolog (CSI2165). Here is my course website.

Romania

• some Romanian art, paintings by my cousin Mircea Nastase
• some images
• Dinel's (Contantin Orasan's) beautiful pictures of Romania and not only, and of my home town - Cluj-Napoca
  
• Dinu Mititeanu's pictures of the gorgeous mountains and landscapes of the Carpathians in Romania
  
• if you want to visit, you may want to try Green Mountain Holidays . You can bike (as hard and as much as you want), hike or just go by car and see how beautiful my country is.

• Romanian personalities, from the past and the present, including Brancusi, Coanda, Titulescu and many others
