Welcome to my homepage!
My name is Sofia Karygianni and I am a PhD student at LTS4, EPFL since July 2010. Prior to that, I was affiliated with the University of Toronto, Canada, where I got my Master degree from the department of Computer Science in 2009. My Diploma degree was obtained from the Electrical and Computer Engineering department of the National Technical University of Athens, Greece in 2007.
My research focuses on learning structure and features from signals. I am particularly interested in low dimensional models (e.g. manifolds) as well as structured sparsity and dictionaries.
