Lars Thorben is a PhD student in Electrical Engineering with focus on numerical methods and optimization. Currently, he works on applying adjoint sensitivity analysis to charged particle optics. His past work includes the optimization of photonic crystal structures and virtual instrumentation for online education. At Stanford, he also works with the d.school as a Creativity and Innovation in Research scholar throughout 2017-2018. Moreover, he is supported by the ERP-Program from the German Federal Ministry of Economics and Energy.
In his personal life, Lars is interested in the societal impact of emerging technologies. He co-founded a think-tank on this issue. Moreover, he likes to stay fit and active by learning how to surf, hosting a bodyweight workout group on campus and attending the gym.
Current Research and Scholarly Interests
Lars's research interest lies at the intersection of optimization, applied physics and numerical methods. He is interested in understanding how we can use modern numerical methods and optimization techniques to improve physical devices in photon and charged particle optics. Hereby, the shape and topology of a device oftentimes plays a crucial role in its behavior. Lars is building computational models, including the application of adjoint design sensitivity analysis, to improve device shapes.
Currently, he is working on electron lensing devices. Other application of such computational tools range from optical tweezers and particle transport, near-field scanning microscopy and optical data storage to X-Ray systems.
While working on his research, Lars also encountered the limitations of todays tools of assisting research publications and outreach. Thus, he worked on the iLabs platform for research outreach and online education. This platform combines an interactive and scalable display of research data with social functionalities.
