Joseph Olwendo received his B.Sc. and M.Sc. in theoretical physics in 2005 and 2008, respectively, from the University of Nairobi. He got his Ph.D. in space physics under the supervision of Paul Baki from Pwani University, Kilifi (Kenya) in 2014. His research interest has been on equatorial ionospheric dynamics and ionospheric plasma density irregularities using GNSS signals over the East African sector. He also works on ionospheric model validation and navigation applications and, since 2015, has been visiting the International Centre for Theoretical Physics (ICTP) on a short-term basis in his capacity as a junior associate scientist. At ICTP he works with NeQuick 2 model research group under Sandro M. Radicella.
