Wilson´s field is analytical chemistry, developing novel approaches for e.g. measuring hormones, drugs, proteins, lipids and environmental pollutants. Primary tools are mass spectrometry and chromatography. Key focuses are analysis of very small biosamples, and automation. In the later years he has focused on diagnostics, primarily in cancer research. Wilson is a part of the convergence environment “Organ on a chip and nano-devices” and the strategic environment “Diatech@UiO”. Multi-disciplinary research is a key to Wilson´s work. He is also an advocate for open access publishing, to make research as available as possible to as many as possible. Wilson is an award-winning lecturer, recently winning the “Lecturer of the Year” award at the Faculty for Mathematics and Natural Sciences
