My research interest primarily focuses on the areas of cybersecurity, cyber investigation, adversarial machine learning, IoT, and workforce development. With the recent and emerging cyber threats to various levels of organizations, I engaged myself in research activities to facilitate a robust, scalable, and adaptable form of strong authentication to mitigate these ongoing threats. My research contributions expanded on all the major scholarship categories--peer-reviewed publications, textbook chapters, patents, and grants. My research portfolio qualified me to receive my permanent residency in the category of outstanding researcher (EB1B).
I received my US citizenship on June 27, 2025.
