Jakob studied Physics at the Swiss Federal Institute of Technology (ETH) in Zürich. During his PhD with Kevan A.C. Martin at the Institute for Neuroinformatics (ETH, Zürich, Switzerland) he developed a layered cortical microcircuit model of the frontal eye fields, a brain region important for the control of eye movement in primates. Jakob then moved to Berlin where he worked with John-Dylan Haynes and developed and applied novel methods to study multivariate and information theoretical aspects of brain connectivity with fMRI. Since 2012, Jakob is a Senior Researcher and Head of Laboratories at the Translational Neuromodeling Unit.
The human brain has an astonishing capacity to control and guide behavior. The neuronal computations that are required for this rely on interactions between populations of neurons. I use mathematical models to understand these cortical computations, how they are performed by the underlying neuronal network and how they might be altered in psychiatric diseases. Hence, I focus on tasks which could provide potential biomarkers in psychiatric diseases such as for example the antisaccade task or saccadic adaptation for eye movements, or predictive coding in sensory hierarchies. The models are used to predict fMRI as well as eye movement data. I also develop methods to analyse high-resolution, layered fMRI to study layered cortical computations in the same tasks.
