Hey there, I’m Victor, a postdoctoral researcher in the Dynamic Macroecology Group at the Swiss Federal Institute for Forest, Snow & Landscape (WSL), Switzerland.
I am broadly interested in understanding and predicting the dynamics of complex systems by developing methods leveraging the extrapolation ability of mechanistic models with the flexibility of machine learning techniques. My main domain of application is ecology, where I focus on understanding the dynamics of ecosystems and their response to disruptions.
Outside of work, I am a part-time alpinist, passionate about mountain adventures and writing. I also enjoy sailing and surfing occasionally. You can check out my alpine CV here.

A minimal JAX library for graph-based connectivity analysis at scales.
StarA Julia library for easily building and training hybrid dynamic models which combine mechanistic and data driven components.
StarSolver for highly dimensional, non-local, nonlinear PDEs. It is integrated within the SciML ecosystem (see below). Try it out! 😃 If you want to learn more about the algorithms implemented, check out my research interests.
StarA zoo of eco-evolutionary models with high fitness.
StarEvolutionary Individual based modelling, mathematically grounded. A user friendly package aimed at simulating the evolutionary dynamics of a population structured over a complex spatio-evolutionary structures.
StarI am a member of the SciML organisation, an open source ecosystem for Scientific Machine Learning in the Julia programming language. On top of being the main author of HighDimPDE.jl, I actively participate in the development of other packages such as DiffEqFlux.jl, a library to train differential equations with data.
StarI am also a reviewer at the Journal of Open Source Software Science (JOSS).
