Bio

I specialize in data hiding applications in digital imagery, including steganography and steganalysis, forensic analysis of digital images (sensor fingerprints), and advanced image processing. My earlier research interests were in chaotic nonlinear dynamical systems and dynamical systems modeling and encryption. I work with a team of my graduate students at Binghamton University. Our research is mostly funded by the AFOSR, NSF, and the AFRL.
