Welcome to my site!!

Hi there! My name is Cristhian Ariel David Deagustini. People usually call me by my middle name Ariel.

I'm a PhD student in Computer Sciences at Universidad Nacional del Sur in the Departamento de Ciencias e Ingeniería de la Computación, under the supervision of Guillermo R. Simari and Marcelo A. Falappa. I'm also member of the Artificial Intelligence Research and Development Lab (LIDIA) and the Knowledge Management and Information Retrieval Research Group. Currently I hold a PhD fellowship from the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET). I also have a "Licenciatura en Sistemas" (graduate degree in Systems) from the Facultad de Ciencias de la Administración (roughly translated to Faculty of Management Sciences) at the Universidad Nacional de Entre Ríos.

My research interests are mainly in Knowledge Representation and Reasoning, and in the dynamic changes of knowledge, specially Knowledge Bases Merging and Belief Revision.
