Selected Projects on Physiologic Forensics
Can we track your heart rate without wearing or touching any sensors, even while you run on a treadmill? How about tracking your breathing? Can we track your ECG continuously without annoying stickers or keep holding onto sensors? Check out our research on physiological forensics exploring micro signals from video and other sensing modalities:

Selected Projects on Media Forensics
When was a video captured? Where? Was the sound track captured together with the visual? Or added on later? Check out our work exploring environmental fingerprint from power grid and many other types of micro signals:

I chaired the IEEE Technical Committee on Information Forensics and Security (IFS-TC, 2012-2013), and was elected IEEE Fellow Class of 2011, AAAS Fellow in 2017 [UMD news], and Fellow of the National Academy of Inventors (NAI) in 2019 [UMD news].
I completed my 3-year term as Editor-in-Chief of the IEEE Signal Processing Magazine (2015-2017), and earlier I served as Founding Chief Editor of the IEEE SigPort online repository and Area Editor of the SPM for creating and editing the monthly "Inside Signal Processing eNewsletter (2007-2010)."
For three years from 2015 to 2017, I wrote a bimonthly editorial as an opening article in each issue of the IEEE Signal Processing Magazine. This collection of editorials (compiled here in a PDF file) was part of my many Editor-in-Chief responsibilities at the time. I valued the opportunity to reflect on a number of topics, from education, to public outreach, to community building, to gender diversity, to the synergy with art and science, and many more.
A special issue on "Digital Forensics" that I edited with colleagues in the IFS-TC appeared in the IEEE Signal Processing Magazine (SPM) in March 2009. An article on "Component Forensics" framework I co-authored was also translated to Chinese as an outreach effort of SPM. [IEEE Xplore, PDF; 中文版]
The paths of engineering and economics/management -- the two college majors I pursued -- crossed again 10 years since graduation, when I served as Finance Chair for IEEE's flagship conference on signal processing -- ICASSP'07. Later I served as Vice President - Finance of the IEEE Signal Processing Society (2010-2012).
I have been the Principal Investigator or Co-PI for several basic and advanced research projects funded by the Department of Defense on information security and forensics. Learn more from my research page.
Several grants have explored micro signals for digital forensics, as mentioned under the "Selected Projects" above. Before that, a 3-year NSF effort of "Fashion," or Forensic Hash for Assured Cyber-based Sensing and Communications, aims at exploring the synergy between multimedia hashing and non-intrusive forensics [UMD news]. Earlier, I had a 3-year NSF effort focuses on addressing physical-layer challenges through cross-layer approaches to wireless secure communications, dubbed as the CLAWS effort [UMD news], and my research on "Signal Processing Approaches for Multimedia Security and Information Protection" was sponsored by NSF through a 5-year CAREER award program ('02-'07) [E@M Magazine news]).
