Nadezda (Nadja) is a past Ph.D. student of the Bakker group who joined us from St. Petersburg State University in Russia. She realized potentiometric sensing arrays for aquatic analysis that were subsequently deployed on a Eawag platform on Lake Greifensee. She also studied how transmembrane fluxes and dynamic electrochemistry can be used to locally acidify the membrane surface for improved anion sensing and spent much time on studying possible ways to measure phosphate. She worked closely with the groups of Bernhard Wehrli and Francesco Pomati at Eawag as part of a SNSF Sinergia project.
After her Ph.D. she did a postdoc at HES-SO Sion and is currently employed as a Sensor Development Engineer at SenTec in Therwil near Basel, Switzerland. Linkedin.
