Dalvan Griebler

I am an Associate Professor at the Pontifical Catholic University of Rio Grande do Sul (PUCRS), and Três de Maio Educational Society (Setrem), Brazil. I was the founder and I am currently the coordinator of the Laboratory of Advanced Research on Cloud Computing (LARCC) at Setrem and research coordinator in the Parallel Applications Modeling Group (GMAP) at PUCRS. I received the Ph.D. in computer science from both PUCRS and University of Pisa (UNIPI) in 2016.
