Dalvan Griebler

I am an Associate Professor and Computer Scientist at the Pontifical Catholic University of Rio Grande do Sul (PUCRS), Brazil. I received a Ph.D. in computer science from PUCRS and the University of Pisa (UNIPI) in 2016. I am part of the School of Technology, lecturing in the Computer Science and Data Science Bachelor courses. I also supervise Master's and Ph.D. students from the Computer Sciences Graduate Program (PPG-CC) and the Ecology and Evolution of Biodiversity Graduate Program (PPG-EEB). As vice-coordinator of the Data Science Center (CCD), coordinator of the natural language processing group (PLN), and research coordinator of both the parallel application modeling group (GMAP) and laboratory of artificial intelligence (Lab AI), I have been developing several research projects with industry partners and governmental agencies. In the academic community, I act on the editorial board of scientific journals, on several technical program committees of conferences, and as a reviewer of several scientific journals.
