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 in June 2025. I’m currently a visiting researcher at the Cambridge Sustainable Computing Lab.

Datacenters are becoming GW-scale consumers of electricity and embodied resources, yet their environmental cost remains opaque and hard to reduce or control. I’m convinced that sustainability can’t be achieved by efficiency alone, nor treated as a governance problem outside the reach of computer science research. My research vision is to make the environmental impact of large-scale computing and AI systems accountable and actionable.

Besides, I’m interested in carbon-aware computing [Middleware'21, e-Energy'24, e-Energy'25], co-simulation of computing and energy systems [HotCarbon'24, SSC'25], and ML systems [NeurIPS'24].

• March 2026: We will present our latest research on distributed LLM pretraining during renewable curtailment windows at the Flower AI Summit in London next month.
• February 2026: Over the next four months, I will be visiting Loïc Lannelongue at the Cambridge Sustainable Computing Lab to work on energy and carbon accounting in computing.
• January 2026: We released version 0.13.0 of Vessim, our energy system simulator for datacenters, focusing on usability and introducing a new, comprehensive documentation.
• Dezember 2025: We will present or position paper Efficiency Will Not Lead to Sustainable Reasoning AI at EurIPS'25 in the workshop on Rethinking AI.
• November 2025: On Nov 14, Exalsius and Flower organize the first [Cold Start:] Distributed AI Hack Berlin. Open to all, sign up!
