Biometrics Research and Development Group (BRAG)

The Behavioral Biometrics Research and Development Group (BRAG) members utilize a variety of biometric patterns (e.g., face, fingerprint, gait, touch, sign, movement) to create smarter, fairer, more reliable, and more accessible computer systems, ultimately contributing to a healthier society. 

Active BRAG members:
