AREA

Data Science & Technology

Rafael Ballester-Ripoll has recently joined the IE School of Human Sciences and Technology as an Assistant Professor in the area of Data Science. Prior to that, he was a Postdoctoral Associate at the Swiss Federal Institute of Technology in Zurich (ETH) and at the University of Zurich (UZH). He holds a PhD in Computer Science from UZH (2017) as well as BSc and MSc degrees in Mathematics and Computer Science from the Technical University of Catalonia-UPC (2012).

His research interests lie in data analysis, explainable artificial intelligence, and visual analytics using modeling tools such as low-rank decompositions, tensor networks, and neural networks. His contributions in large-scale scientific visualization, data compression, and uncertainty quantification using these tools have been published in IEEE Transactions in Visualization and Computer Graphics, Computers & Graphics, and the SIAM/ASA Journal on Uncertainty Quantification, among other journals. He also partakes regularly in academic conferences including IEEE VIS, EuroVis, SIAM meetings, and various symposia on tensor methods.
