Johann Riemensberger
Om
Jeg studerte fysikk ved Technische Universität München (TUM). For min diplomoppgave jobbet jeg hos Tobias Kippenberg ved École Polytechnique Fédérale de Lausanne (EPFL), hvor jeg var pioner og etablerte den Si3N4-baserte plattformen for ikke-lineær integrert fotonikk for frekvenskamgenerering. Etter min fysikkdiplomgrad (med utmerkelse) vendte jeg tilbake til mitt alma mater TUM og min mentor Reinhard Kienberger for å ta en doktorgrad i attosekundfysikk i august 2012. Jeg utførte eksperimenter ved faststoff-attosekund fotoemisjonsstrålelinjen, som resulterte i publikasjoner i Nature og PRL. Siden februar 2019 har jeg vært postdoktor i Tobias Kippenbergs laboratorium for Photonics and Quantum Measurements a EPFL, Sveits. Jeg har demonstrert nye tilnærminger for massivt parallel koherent laseravstandsmåling ved bruk av soliton-mikrokammer, optisk koherenstomografi og parametiske forsterkere basert på integrerte fotoniske kretser. Jeg er mottaker av et Marie Skłodowska-Curie Individual Fellowship fra Europakommisjonen og et Ambizione Fellowship fra det sveitsiske nasjonale forskningsrådet. For tiden har jeg blitt tildelt Onsager Fellowship og stilling som førsteamanuensis ved Norges teknisk-naturvitenskapelige universitet (NTNU). Mine nåværende forskningsinteresser er utvikling og anvendelse av ultra-lavtaps ikke-lineær fotonikk basert på nye materialplattformer som litiumtantalat og galliumfosfid.
