Biography
I’m Victor, a $4^{th}$ year Ph.D candidate in the Landscape Ecology Group at ETH Zürich and at the Swiss Federal Institute for Forest, Snow & Landscape (WSL), Switzerland.
My Ph.D aims at better understanding evolutionary processes that affect the dynamics of ecosystems and economic systems. I conduct my investigations with mathematical models capturing eco-evolutionary dynamics. In parallel, I develop machine learning methods to confront these models with empirical data and infer scientific knowledge. I believe that the combination of mechanistic models and machine learning provides a powerful approach to better understand our world. This is crucial, in the face of potentially important ecosystem changes and accelerating threats.
Besides work, I am passionate about alpine adventures and spend my freetime climbing and going down mountains 🏔 , be it with chalk, ice-axes, skis, or a mountainbike. You can check out my alpine CV here.

Open source as a philosphy.
EvoId.jl
Evolutionary 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.
StarHighDimPDE.jl
Solver 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.
StarEcologyInformedML.jl
Suite for fitting ecological time series to mechanistic models.
StarSciML
I 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).
