SEGH Fellows

In May 2019, the board of SEGH created a new level of membership: Fellow. 

This is an invitation-only membership level and reflects the fact that the individual concerned has been very active within SEGH, or within the field which SEGH represents.

Do you know someone who you think should be a Fellow? If so, please write to the board, ( suggesting why you think this should be the case, providing some background to this person. The board will then consider the proposal, and make an invitation to that person, if appropriate.

Sanja Potgieter-Vermaak


Sanja Potgieter-Vermaak is a Senior Lecturer in Analytical Chemistry at Manchester Metropolitan University in Manchester, UK. She heads the environmental change research group in the Ecology and Environmental Research Centre at MMU. Her research focus is on the health effects of air pollution (using various in-vitro techniques) and she has expertise in the monitoring and chemical characterisation of airborne particles for different geochemical origins, as well as indoor environments. The emphasis is specifically on the inhalable size fraction (using novel techniques e.g. InSEM-Raman) and source apportionment of transition metals. Dr. Potgieter-Vermaak published 91 papers in prestigious journals for e.g. STOTEN, Atmospheric Environment and Environment International. She has been the lead researcher in air pollution monitoring and characterisation projects in Belgium and produced several reports on the findings.

Prof Taicheng An
