About
Marjory is passionate about computing and artificial intelligence.
Her main area of research is applied artificial intelligence, more specifically, data-mining and machine learning applied to user data analysis and biometrics (face analysis, emotion prediction, keystroke, mouse and touch dynamics, fingerprint, handwritten text, signature and voice/speech). Some of my ongoing projects are: medieval document analysis ; transparency in user behaviour in commercial game playing; signal processing (speech analysis) applied to medical diagnosis and neurological diseases therapy; forensics-based keystroke dynamics analysis applied to accountability concerns in social networks; mining judges’ sentences for analysing fairness; mining hard real-time network environments and investigating machine learning-based decision engines for network intrusion detection systems; and designing cheaper technological solutions for biometrics applications in different scenarios.
She has won the Newton Research Collaboration Programme Award and has strong collaborations with the University of Kent (UK) and the University of York (UK) and she has been working in several different projects.
She worked as a Reader in Artificial Intelligence at UFRN until 2019.
