Sampson is a Linguist with the Department of Ghanaian Languages and Linguistics, University of Cape Coast, Ghana. He received his Ph.D. from the IGRA Gradschool at Universität Leipzig, Germany. His research broadly focuses on theoretical issues in the syntax and morphology of Kwa (Niger-Congo) languages of West Africa, especially Gã and Akan (both spoken in southern Ghana).

He is, presently, the Local Investigator for Akan in the European Research Council-funded LeibnizDream Project.
