Patrick Essien

Lecturer and Research Scientist

Patrick Essien holds a PhD in Space Geophysics from National Institute for Space Research in Brazil. His research interests focus on the effects of space weather and ionospheric conditions on Global Navigation Satellite Systems (GNSS) and their applications. He also does research into the neutral atmospheric forcing and its effects on the ionosphere. Depuis ORCID
