About me

I am currently a postdoc in the NWO VICI Project on Collective Information led by Ulle Endriss, working on topics related to Computational Social Choice.

Prior to this I was a research assistant and PhD student at TU Wien, in Vienna, Austria. This is my former webpage.

Grants

Over the years I have been fortunate enough to receive support from a number of sources.

I was the beneficiary of a KUWI grant from TU Wien for a short-term stay abroad in Paris, at Univ. Paris-Dauphine, from October to December, 2017. I was then awarded a Marietta Blau grant from the OEAD for a stay abroad, also in Paris and also at Univ. Paris-Dauphine, for the period February-July, 2018.

During this time I collaborated on some papers, saw the Bois de Boulogne go from green to grey to luscious green again, and listened to gospel music in the Saint-Vincent de Paul church.

I was hosted in Paris by Jerome Lang, to whom I am very grateful. Under his guidance I visited Toulouse and got to meet and collaborate with Umberto and Arianna.

The Paris stay also resulted in a collaboration with Meltem, Stefano and Hossein.

I'm additionally grateful to Nadia and Odile, who hosted me in Marseille at the end of January.

In 2015 I was able to attend IJCAI 2015 in Buenos Aires, Argentina, thanks to a travel grant from the IJCAI organization. During my EMCL studies (2012-2014) I lived off a scholarship granted by the EMCL fund, without which I would probably not have been able to attend the program.


Academicalia

I helped organize:

The Workshop on New Trends in Formal Argumentation, August 17, 2017, Vienna, Austria
The Workshop on New Trends in Belief Change, May 10, 2016, Vienna, Austria
The EMCL Student Workshop, February 18-19, 2014, Vienna, Austria

What else? Oh yes: I was a volunteer at IJCAI 2018, KR 2018, KR 2016 and the Bucharest Colloquium in Analytic Philosophy 2011. I was involved in web-site maintenance for the projects that employed me, for the EDBT-ICDT 2018 conference and, from 2008 to about 2010, I co-edited the Romanian Philosophy Newsletter.
