About

Nana Kena Frempong is an Associate Professor in the Department of Statistics and Actuarial Science at the Kwame Nkrumah University of Science and Technology, Kumasi, Ghana. He received a Ph.D. in Mathematical Statistics from the Kwame Nkrumah University of Science and Technology in October 2017. He was awarded two Master’s degrees in Applied Statistics and Biostatistics respectively, at the Universiteit Hasselt, Belgium, in 2007. His primary research interest is in the theory of estimation which focuses on deriving methodologies that help to improve statistical learning. He is interested in identifying new ways to apply methods from different disciplines in new settings. This includes modifying methodology from one area of statistics so that it may be applied in a separate area, or through applying statistical methods to novel problems in the real world of data analysis. Currently, he is involved with some data science techniques in Machine Learning. Nana Kena Frempong is passionate about the value of statistical thinking, and the use of statistical techniques as a means for improving decision-making. He collaborates with other scientists from engineering, biochemistry, building and construction. His passion is to make students understand the subject matter. He has a number of publications in referred journals and has published more than forty (40) articles in the Mathematics, Finance, Economics, and Statistics literature.
