Education and career
Katsaggelos received a diploma degree in electrical and mechanical engineering from the Aristotle University of Thessaloniki in 1979, and M.S. and Ph.D. degrees in electrical engineering from the Georgia Institute of Technology in 1981 and 1985, respectively.[7] He joined Northwestern University in 1985.[7]
At Northwestern, Katsaggelos is the Joseph Cummings Professor of Electrical and Computer Engineering and has courtesy appointments in computer science and radiology.[1] His Northwestern profile lists him as director of the Image and Video Processing Lab, co-director of the Center for Scientific Studies in the Arts, and deputy director of computation at the Center for Computational Imaging and Signal Analytics in Medicine.[1]
Katsaggelos has also held editorial and service roles in the IEEE Signal Processing Society. The society's Leo L. Beranek Meritorious Service Award list records that he received the 2001 award for service to the society, including service as editor-in-chief of IEEE Signal Processing Magazine.[8]
Research and applications
Katsaggelos's research areas include image and video processing, multimedia signal processing and communications, computational imaging, computer vision, machine learning, and medical and biological signal processing.[1] His IEEE Fellow citation recognized his work on iterative image restoration methods,[2] and the IEEE Signal Processing Society Technical Achievement Award cited his contributions to image and video processing.[4]
In cultural heritage imaging, Katsaggelos worked on computational methods for analyzing and colorizing historical images of artworks. MIT Technology Review en español described image-processing work by Northwestern researchers that used information from earlier versions of Henri Matisse's Bathers by a River and from the painting itself to help colorize a 1913 black-and-white photograph of the unfinished painting.[9] In a Britannica video transcript about the same project, Art Institute of Chicago curator Stephanie D'Alessandro said the museum came to work with Katsaggelos because he could help visualize how the painting would have appeared at the time of the archival photograph.[10]
His computational imaging work has also been reported in connection with studies of works by Pablo Picasso. In 2018, the Greek newspaper To Vima reported that Katsaggelos contributed computational methods used to reconstruct missing pixels in X-ray fluorescence data to improve imaging of artwork beneath Picasso's La Miséreuse accroupie.[11]
In medical imaging, Katsaggelos was a senior author of DeepCOVID-XR, an artificial intelligence system studied for detecting COVID-19 on chest radiographs.[12] CBS Chicago described Katsaggelos and Ramsey Wehbe as leading a Northwestern team that trained and tested DeepCOVID-XR on 17,000 X-rays.[13] ERT News, Greece's public broadcaster, also covered the project and described Katsaggelos as the artificial-intelligence specialist heading the research team.[14] CIDRAP News, MedCity News, and Fierce Biotech reported on the system's use of machine learning to screen chest X-rays and quoted Katsaggelos on its intended use as a rapid screening aid rather than a replacement for diagnostic testing.[15][16][17]
Katsaggelos has also been involved in artificial-intelligence research in astronomy. In 2025, The Daily Northwestern described him as deputy director of the NSF–Simons AI Institute for the Sky and reported that he was involved in SkAI projects using machine learning in astronomy, including work on galaxy distortion and latent-space methods.[18]
