I am a Lecturer here at the Department of Mathematics, KNUST, where I also obtained my mathematics degrees. I was briefly a Visiting Lecturer at the University of Roehampton, London (Functional Skills, Foundation Programme) before joining KNUST. My research centres on developing methods in analysis—real, complex, harmonic, and functional—to tackle problems in (analytic) number theory, (linear and nonlinear) operator theory, and (convex & discrete) geometry, largely concentrated around certain specific projects. I am part of the Algebra and Topology Group here at KNUST, co-organised with Bernard Bainson, and I also organise the semesterly MaTH-Challenge Prize Problems. You can have a look at my papers and preprints.

I have, over the past few years, been a Visiting Lecturer at AIMS, Ghana, lecturing variously on number theory, topology and geometry, and functional analysis.
