I’m a postdoctoral researcher at TU Berlin in the Distributed and Operating Systems (DOS) group led by Prof. Odej Kao, where I completed my PhD with distinction in June 2025.
I’m currently a visiting researcher at the Cambridge Machine Learning Systems Lab.
Vision & Interests
Datacenters are becoming gigawatt-scale consumers of electricity and embodied resources, but their environmental impact remains difficult to measure and control.
My research develops methods to quantify and reduce this impact in large-scale computing and AI systems.
I also study how datacenters can use their flexibility to stabilize the electrical grid and accelerate decarbonization.
I believe sustainable computing will require more than efficiency, and that computer systems research has an important role in informing policy and governance.
I’m interested in research at the intersection of computing and energy systems, such as carbon-aware computing [Middleware'21, e-Energy'24, e-Energy'25], modeling and analysis [HotCarbon'24, SSC'25], and efficient ML systems [NeurIPS'24, HyperAgents'25].
