My name is Grigorios Tsagkatakis and I am an associate researcher at the Signal Processing Lab (SPL) of the Institute of Computer Science (ICS), Foundation for Research and Technology Hellas (FORTH). I am currently working on the PHySIS and the DEDALE EU projects with Professor Panagiotis Tsakalides.

I hold a BSc (2005) and an MSc (2007) from the School of Electrical and Electronics Engineering, Technical University of Crete, Greece. I was awarded my PhD in Imaging Science from the Center of Imaging Science, Rochester Institute of Technology, NY, USA in 2011.

Research Interests
Signal and Image Processing, Machine Learning, Compressed Sensing, Matrix Completion, Manifold Learning
