I am pharmacologist by training, and basic science researcher interested in the design, preclinical testing and commercialisation of novel, inexpensive anti-inflammatory drugs.
My interest in the field of inflammation began in 2000 at the laboratory of Professor S. H. Ralston at the University of Aberdeen and University of Edinburgh (Scotland, UK), where I obtained a Ph.D. in Medicine, and underwent my early postdoctoral training. During this period, I carried out significant research examining the therapeutic (and harmful) effects of plant-derived and synthetic anti-inflammatory substances, which culminated in first- and last-author publications in a number of prestigious scientific journals including Nature Medicine, Cell Metabolism and Ageing Cell, and the foundation of OsteoRX Ltd. - a start-up company established to develop novel anti-rheumatic drugs. As principal investigator, at the Edinburgh Cancer Research Centre (Scotland, UK, 2010-14) and University of Sheffield (England, UK, 2014 - present), my pharmacological research led to the design and preclinical testing of a novel class of small-molecule inhibitors of NFκB and the foundation of arthElix Ltd.
Outside the laboratory, my academic and research interests varied. These are some of the ongoing projects.
I am a data science enthusiast. In 2021, I founded the Africa in Science (AiS) think-tank that monitors the scientific output of Africa-based institutes, with the aim to uncover under-researched and neglected topics in Africa.
I am an avid supporter of issues and needs of early-career researchers. In 2019, I founded and served as Editor-in-Chief of HubLE.org, the IFMRS Learning and Sharing Environment.
I have been especially interested in positive ethnic discrimination in science, as a result of personal experience.

- Research interests
-
The primary interest of my group is pharmacology of inflammation. The specific aims of our research are to:
- uncover novel druggable pro-inflammatory transduction pathways essential for the regulation of cancer – immune - bone cell interactions, and guided by these studies
- design and test novel therapeutic agents - alone or in combination with drugs in clinical practice - for the treatment of chronic inflammation associated with bone diseases and cancer.
Current Projects
- Targeting of IKK-Epsilon alone or in combination with chemotherapeutic drugs for breast cancer treatment.
- Regulation of adipocyte – cancer cell crosstalk by NFkB signalling.
- Role of TRAFs/NFkB signalling in inflammation associated with metastatic cancer.
- Role of RANK/NFkB signalling in cancer cell behaviour in bone.
- Regulation of bone – immune – malignant cell interactions by the Endocannabinoid/NFkB axis.
