My primary research interest is to understand how cortical neurons are adapted to their environment i.e., the circuit they are embedded: the computation it performs and the activities of the other neurons. In my research I combine ideas from systems neuroscience and machine learning with single neuron modelling and data analysis to characterise the spatio-temporal distribution of natural activity patterns in neuronal populations and to capture the response of single neurons to stimuli sampled from this distribution. This approach has the potential to reveal the contribution of specific single neuron properties to the computation performed by the network.

Balázs Ujfalussy earned his PhD from Eötvös University under the supervision of Péter Érdi and Tamás Kiss studying the formation of spatial representations in the hippocampus. In 2011 he was awarded a Marie Curie Posdoctoral Fellowship and joined the group of  Máté Lengyel at the Computational and Biological Learning Lab at the University of Cambridge to study the role of nonlinear dendrites in spiking networks. In 2014 he worked with in the MRC Laboratory of Molecular Biology (Cambridge, UK) with Tiago Branco where he modelled the response of cortical neurons to synaptic stimuli with complex spatio-temporal structure. He is currently an MTA postdoctoral fellow in the Lendület Laboratory of Neuronal Signaling with Judit Makara and joined the efforts of the PATTERN group in 2015.
