Visiting Researcher at University of Cambridge
Berlin, Germany
Summary
👤
Senior🎓
Top SchoolPhilipp Wiesner is a researcher-engineer bridging distributed systems, machine learning, and sustainable energy, with 11 years of industry and academic experience spanning startups and top universities. He completed a PhD on carbon-aware optimization at TU Berlin and now works on enabling renewable-aware distributed AI—both as a postdoc and as a research scientist at Exalsius, where he helps automate multi-cloud GPU cluster provisioning. His contributions to cloud simulation (notably improving power modeling and network APIs in the popular CloudSimPlus framework) reflect a pragmatic focus on accuracy and maintainability. Philipp’s background ranges from building RNN-based extraction pipelines and large-scale training infrastructure to production data platforms, giving him a rare blend of hands-on software engineering and systems-level research. Based in Berlin, he frequently combines open-source work with field deployments to close the gap between renewable-aware algorithms and operational GPU fleets.
