I am a tenure track assistant professor at the University of Twente (UT). My reserach focuses on using plasmonic nanocavities to enhance light-matter interactions with bio-molecules. I use novel approaches to enhance optical fields at the nanoscale, for ultrasensitive sensing and to probe bio molecular dynamics. I am leading the Dynamic Nanophotonic team that is currently hosted by the Optical Sciences chair, which is part of the department of Applied Nanophotonics at the UT. 

Before joining UT, I was a postdoctoral researcher at the NanoPhotonic Center, Cavendish Laboratory, University of Cambridge from 2017 to 2020 and my research focused on light-matter interaction in ultrasmall mode volume plasmonic nanocavities. This research was funded by the NWO Rubicon fellowship. In 2016, I obtained a PhD degree (cum laude) from the University of Twente, and worked on controlling and enhancing optical energy density (using wavefront shaping) inside complex nanophotonic systems. Prior to that, I obtained a master’s degree in photonics from the Abbe School of Photonics at the University of Jena, Germany and a bachelor in physics/electronics from the Federal University of Technology, Minna, Nigeria.
