I am a first-year Ph.D. student under the supervision of Professor Mauro Cherubini and co-supervised by Professor Kevin Huguenin in the Department of Information Systems, HEC Lausanne. My doctoral research centers on the effects of cyberbullying among marginalized communities such as young and less privileged people. I hold a Master's degree in Information Technology from University Utara Malaysia and a Bachelor’s degree in Business Information Systems from the University of East London. My Master’s thesis investigates the factors that determine the use of e-government systems in Higher Education institutions in Nigeria. I started my career as a primary school teacher (2013) and rose to the level of Assistant Lecturer from State to Federal University in Nigeria, where I tutored both undergraduate and postgraduate courses such as Management Information Systems, E-Business, and Computer Applications.

I am a PhD student in the Department of Information Systems at the University of Lausanne, supervised by Professor Mauro Cherubini. My PhD research tackles the next frontier in social media safety and privacy in three ways:

(1) Investigating Personal Information Disclosure: By examining the role and form of personal information disclosure in cyberbullying incidents across diverse and representative samples from the USA and Nigeria, my research sheds light on how cultural factors influence cyberbullying behaviors and victimization patterns.

(2) Participatory design with Young Adults in Switzerland: In the second phase of my research, I break new ground by involving young adults in Switzerland, a group often underrepresented in cyberbullying research, in the co-design process of solutions, to ensure that the solutions reflect their needs, concerns, and desires.

(2)Developing and Testing a Real-Time Support Application in Nigeria: In the third and final phase of research, I developed and tested a real-time application for students in Nigeria that offers a multitude of support options, including informational resources, peer-to-peer interaction, and access to counseling, to empower victims seek the immediate needed support.

Together, these three approaches provide a comprehensive and universal perspective on cyberbullying, addressing the issue from multiple cultural, regional, and practical angles.
