Tom Tirer
 

Research

My research interests are in the fields of signal and image processing, machine learning, optimization, and their interconnections.

My lines of research include (but not limited to):

I'm looking for self-motivated graduate students with strong academic record that are interested in doing research on theory and applications in these fields. If you are interested, you are more than welcome to send me an email with your CV and academic record so I can understand your background.
