My major research activities have been in the design, study, optimization and operation of storage rings. The contributions have been theoretical, computational, as well as experimental across all areas of accelerator physics and also involved many hardware projects. The goal was to substantially improve the accelerator performance of several facilities. This included work to increase the beam intensity or reduce the beam emittance, both leading to higher luminosity or brightness, work to enable new characteristics like polarized beams or special (ultrashort) time structures, work to improve stability and thereby enable ultra-sensitive experiments, or work to improve operational excellence and reliability. The performance and upgrade history of the ALS as well as the advanced technology and physics design behind ALS-U are the main manifestations of this work.

I was the System manager for ALS-U Accelerator Systems throughout the R&D and design phase, responsible for the design, manufacturing and commissioning of the ALS-U accelerator, and am now the ALS-U System Manager for Accelerator Physics and Commissioning.
