I am a Research Scientist at Facebook AI Research in New York, working on machine learning and computer vision. Before, I worked as an Assistant Professor at Delft University of Technology, as a post-doctoral researcher at UC San Diego, and as a Ph.D. student at Tilburg University. I am interested in a variety of topics in machine learning and computer vision. Currently, I am working on learning embeddings for visualization and deep learning, time series classification, regularization, object tracking, and cost-sensitive learning.
