For thousands of years explorers were inspired by the sight of uncharted shores, or by the defiant look of new and higher peaks - right after having overtaken the last. Others rejoiced with the discovery of a new star cruising across the sky, and thrived when realizing that they could predict where the bright dot would be with the passing of time.
Me? I'm fascinated by our understanding of the information contained in signals: from the image of the mountain peak to immunohistochemistry images in digital pathology. This understanding is often formalized through the construction of models, thereby capturing the information contained in these different data sources. If successful, one can deploy these constructions to tackle inverse problems of different kinds, prediction, clustering and other machine learning tasks, and more.
I am an Assistant Professor in the Biomedical Engineering Department at Johns Hopkins University, and I'm affiliated with the Mathematical Institute for Data Science (MINDS) and the Center for Imaging Science (CIS). I received my Bioengineering degree from UNER (Argentina) in 2013, and my PhD in Computer Science from Technion in 2018 with Miki Elad. My research interests are focused on general signal and image processing, sparsity-inspired modeling, machine learning and their application to biomedical sciences.
I'm looking for excellent and motivated students to work with. If you are interested in tackling some fascinating problems in the frontier of machine learning and biomedical sciences, contact me.
