Dr Joost Nelis currently works as a Marie Curie Early Stage Researcher at the Institute for Global Food Security at Queen’s University Belfast. His work focusses on the development of smartphone-hyphenated devices for the detection of major food contaminants. Joost is a very motivated researcher in the field of analytical chemistry/biosensing for point-of-site food contaminant detection. The research he has conducted in the past three years resulted in the development of smartphone-based colorimetric, plasmonic and electrochemical devices for the detection of various marine toxins and allergens. Joost has published eight peer reviewed articles on this topic in the past three years. He is also actively involved in the development of the first, freely accessible, database on biosensors for food contaminant detection (http://test.foodsmartphone.net/).
