About Me

Mon, 01 Jan 0001 00:00:00 +0000

👋 Hi I’m João! #

I’m a Senior AI Researcher focused on Computer Vision and Biometrics. Over the last four years I’ve worked across identity verification and secure face recognition: shipping production systems and publishing applied research. The main areas I’ve tackled: face image attack detection (presentation, deepfake, morphing, adversarial) and core pipeline pieces like ICAO-compliant face image quality and face recognition.
