About Me

I am a 4th-year PhD candidate in the Statistics program at the University of Michigan, Ann Arbor. I come from Mpraeso, a beautiful small town in the Okwahu plains in the eastern region of Ghana. I obtained my MS degree in Statistics & Data Science at the University of Nevada, Reno. Before that, I received my BS in Actuarial Science from Kwame Nkrumah University of Science and Technology.

I am working under the supervision of Prof. Kerby Shedden, currently focusing on using flexible, non-parametric methods to study the full conditional distribution of a response variable, especially in complex and high-dimensional data scenarios.

When I have some time to spare, I enjoy listening to music, spending time with my friends and family and watching soccer (I’m a staunch fan of Manchester United).
