Vsevolod Nedora, PhD
I live in Cologne and work at FlexPower, where I develop and run strategies for Europe's day-ahead and intraday power auctions, and designed a backtesting engine that replays EPEX SPOT order books order by order, latency and slippage included. Before that I was an astrophysicist: a PhD on neutron-star mergers in Jena, then a research project at the Max Planck Institute for Gravitational Physics, where I wrote PyBlastAfterglow.
In both worlds, the work I enjoy most is the same: take a noisy system, build the model and the software around it, and test both honestly against what really happened. I like owning that loop from first sketch to production, and these days I share much of it with AI agents. Stromlens, my own project, is built that way.
Now building
Stromlens
An independent forecasting platform for Europe's power grids: event-driven, probabilistic forecasts built from public weather, grid and market data, published with their track record and their sources.
It started in 2024 as a rough idea: a pipeline for week-ahead electricity-price forecasts. I fleshed that idea out with AI agents, in agent-assisted development, and it grew into Stromlens.
Earlier projects
Energy Heartbeat
A time-aware knowledge graph of European energy news. A daily pipeline scrapes and cleans 13+ sources (grid operators, regulators, markets, analysis), chunks the articles and extracts time-stamped entities and relations to answer "as of" and "what changed" questions.
PyBlastAfterglow
A C++ code with a Python interface for modelling light curves, spectra and sky maps of gamma-ray-burst and kilonova afterglows. It solves the hydrodynamics of shock fronts and the evolution of electron distributions, and computes synchrotron and synchrotron self-Compton emission.
Research
My research was on binary neutron-star mergers: numerical-relativity simulations of the merger and the matter it throws out, and the electromagnetic signals that follow, from kilonovae to the radio and X-ray afterglows of gamma-ray bursts.
Recent first-author papers
Away from the desk
Photography
Sunsets, cloudscapes and close-up details of nature. I try to capture the calm in them.
Science fiction
Stories about how technology, culture, psychology and science may shape the people of the future. Most are in Russian; the newer ones, like The Orchestrated Rain, are in English.
Teaching and mentoring
I lectured and tutored computational physics and astrophysics in Jena and Bonn, and I am always glad to share what I know.
