His research interests include classical and quantum noise, few-cycle and ultralow jitter femtosecond lasers and sub-cycle optical waveform synthesizers, precision timing distribution and integrated optics, compact electron and x-ray sources, terahertz generation and acceleration and attosecond science. He also co-founded Cycle GmbH, a Hamburg-based company, that manufactures precision timing and frequency distribution systems for large-scale scientific infrastructures and industry. He is a Fellow of Optica and IEEE and was honored with the 2022 IEEE Laser Instrumentation Award and the UNIPRENEURS Award in 2023.
