Based on Reflux Design
About Me
I am a PhD Research Fellow in Informatics at the University of Bergen (UiB), supervised by Nello Blaser. My research focuses on the Parameterized Complexity of computing Lineal Topologies (depth-first spanning trees) motivated by applications in AI, network design, and data visualization. I have a previous research experience in Machine Learning gained in my role as a research trainee and through my participation in a series of summer schools in computer science organized jointly by University of Cape Coast (UCC), Ghana, and Academic without Borders, Canada (AWBC). I studied the stability and controlability of the Echo State Network Model using various benchmark and real-time sequential data sets and analyzed its dynamics using recurrence plots.
Before I joined UiB, I was a Lecturer/IT Solutions Developer/MIS Analyst (2012 - 2019) at Wisconsin International University College , Ghana. I taught and mentored students, and leveraged technology and data to improve university operations and processes.
