Prof. Dr. Kirsten Moselund

Kirsten Moselund was appointed by EPFL as full professor of electrical and microengineering in the Faculty of Engineering and Technology. At the same time, she is head of the new Laboratory of Nano and Quantum Technologies (LNQ)  at Paul Scherrer Institute from 2022. LNQ currently has seven groups – two focusing on nanotechnology and advanced nanomanufacturing, four groups focusing on different technologies for quantum computing and her own group Integrated Photonics and Nanoelectronics (IPN). The ETHZ-PSI Quantum Computing Hub is located at PSI and embedded within LNQ, and at the same time Kirsten Moselund is part of the EPFL Quantum Science and Engineering center (QSE). The purpose of this constellation is to promote synergies between the three large ETH institutions.

Kirsten Moselund received the M.Sc. Degree in Engineering from the Technical University of Denmark (DTU) in 2003 and the Ph.D. Degree in Microelectronics from the Swiss Federal Institute of Technology in Lausanne (EPFL), Lausanne, Switzerland, in 2008. In 2008, she joined the IBM Research Europe in Zurich, where she took on a number of different positions and lastly managed the Materials Integration and Nanoscale Devices group with around 20-25 engineers and scientists. The group worked on a broad range of topics from Neuromorphic computing, nanoscale thermometry, topological devices, nanophotonics to control electronics for quantum computing.

Throughout her career, she has worked on various topics related to semiconductor devices and technology development, such as low-power electronics, cryogenic electronics, integrated photonics, topological devices and neuromorphic computing. She received an ERC starting grant on the development of hybrid photonic-plasmonic nanolasers, and an ERC advanced grant NEON in 2025 – for developing random lasing for neuromorphic photonics. She is co-founder of the start-up Rayd and author/co-author of more than 100 papers and has 30+ patents filed.

The Laboratory for Nano and Quantum Technologies (LNQ) is one of the seven laboratories in the Photon Science (PS) Division. The LNQ is responsible for the operation of the cleanroom at PSI and is hosting the ETHZ-PSI Quantum Computing Hub.

In addition to being full professor of electronics and photonics at EPFL, Kirsten Moselund is adjunct professor of the technical university of Denmark, DTU. She is a member of the Swiss Quantum Commission,  member of the Wissenschaftliche Beirat of IHP Microelectronics, and serves on the executive board of Swiss Photonics and Swiss PIC. 

She has served as Principal Investigator (PI) in several EU and Swiss research projects. She is part of various technical program committees for a number of scientific conferences. Most notably IEDM which takes place every year in San Francisco and where she served on  the executive committee from 2013 to 2024, in 2024 she was general chair.

Kirsten Moselund's own research interests include nanophotonics, III-V electronics and nanotechnology. Her research is characterized by the combination of semiconductor technology development and device physics that enables her to design innovative devices. Current research topics include monolithically integrated III-V photodetectors on silicon for high-speed or single photon detection in the NIR. Hybrid photonic crystal lasers combining III-V gain material and silicon resonant structures in particular designed for topological mode emission, as well as the exploration photonic neuromorphic computing based on random lasing in III-V platforms.

She is fascinated by technology development in general and at PSI a main task was the construction of PICO a new cleanroom in Park InnovAare , which opened in early 2024.
