OxTalks is Changing
On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Computational modeling of cell decision processes
My group uses computational approaches in collaboration with experimental labs to develop better mechanistic understanding of cell decision processes. One of the major challenges in modeling these systems is that the molecular constituents of signaling networks interact in a multitude of ways to form densely connected networks involving hundreds to thousands (and beyond) of distinct biochemical species. Rule-based modeling is an approach to modeling complex biochemical networks in which signaling molecules are represented as structured objects whose interactions are governed by rules, which serve as generators of the species and reactions that comprise the network. This approach enables concise and precise encoding of known molecular biochemistry, freeing the modeler from having to explicitly enumerate the large number of possible species and reactions that can arise in such systems. BioNetGen, which is developed and maintained by my group, is one of several rule-based modeling platforms that enable scalable specification and simulation of large-scale models of signal transduction and other biochemical systems. In recent years its capabilities for modeling, simulation, and analysis have been greatly expanded and It has been used to model and gain mechanistic understanding of number of important signaling processes. Here, in addition to providing a general introduction to rule-based modeling and describing some recent developments, I will present two applications to diverse systems: T cell differentiation in the immune system and dopamine uptake in the nervous system.
