Emanuela Marasco, Ph.D.

Assistant Professor

Emanuela Marasco is an Assistant Professor in the Department of Information Sciences and Technology. Before joining George Mason University, she was an Adjunct Professor and a Post-doctoral Researcher in Pattern Recognition and Biometrics at the University of North Carolina Charlotte, Department of Computer Science. From 2011-2014, Dr. Marasco was a post-doctoral Associate Researcher in the Lane Department of Computer Science and Electrical Engineering, West Virginia University. She received a five-year degree (Bachelor and M.Sc.) in Computer Engineering, in March 2006, and a PhD in Computer and Automation Engineering, in December 2010, both from the University of Naples Federico II, Italy.  Her research interests focus on pattern recognition, machine learning, image processing, computer vision, and biometrics. Specifically, she is addressing vulnerabilities and challenges of biometric systems through design and development of: (1) anti-spoofing countermeasures in fingerprint recognition systems, (2) algorithms for automatic enhancement of fingerprint sensor interoperability to maintain data independence from underlying device, (3) image de-identification techniques for privacy enhancement, (4) automatic estimation of soft biometrics (e.g., age, gender) from fingerprints, and (5) adaptive schemes for human identification based on degraded DNA samples. her current sponsors are NSF, DHS and DARPA.
