Modeling strategy based on Petri-nets
In my talk I will introduce a formal modeling strategy based on Petri-nets, which are a convenient means of modeling biological processes. I will illustrate the capabilities of Petri-nets as reasoning vehicles using two examples: Haematopoietic stem cell differentiation in mice, and vulval development in C. elegance. The first system was modeled using a Boolean implementation, and the second using a coarse-grained multi-cellular Petri-net model. Concepts such as the model state space, attractor states, and reasoning to adapt the model to the biological reality will be discussed.

From Camels to Worms: Novel Approaches for Drug Discovery in Parkinson’s Disease
The discovery of novel treatments for neurodegenerative diseases, such as Parkinson’s disease, represents one of the biggest scientific challenges of the 21st century. The development of new tools and models to study the mechanisms underlying neurotoxicity is therefore essential. During my talk, I will outline new strategies for drug design and innovation used during my PhD at the University of Cambridge, which include the combination of fluorescent nematode worms, camelid antibody fragment technology and chemical compounds. These novel approaches will help us to gain insights into the key pathogenic steps involved in Parkinson’s disease and potentially lead to new therapeutic strategies.
