I currently work on the taxonomy of various groups/genera in the Urticales and a variety of plant groups that have representatives on the Horn of Africa (see the list of my publications). In 2022 I published together with colleagues from Ethiopia, Luxemburgh and the Netherlands a monograph describing and analysing the vegetation in western Ethiopia between the highlands and the extensive lowlands in the Nile Valley in the Sudan and South Sudan, and in 2023 a paper on the regeneration of the dry Afromontane forest of thentral Ethiopian highland. An analysis of the scientific plant names commemorating Pehr Forsskål is in press.
