Katerina Kalou

Postdoctoral Researcher

Katerina is a Bioengineering and Biorobotics doctoral graduate from the University of Genova, Italy, with a Msc degree in Cognitive Neuroscience from the University of Trento and a Diploma degree in Psychology from the University of Athens, Greece. She has previously worked as a junior postdoc in the lab of Prof.Redmond O’Connell in the areas of visual perception and decision making using EEG/ fMRI and psychophysics.

Katarina will join the lab in Sept. 2023.

Lucía Arancibia

Doctoral Student


Lucía studied Biomedical Engineering at the UPM in Madrid, where she became interested in the interface between neuroscience and engineering. She then studied a Master of Science in Neurotechnology at Imperial College London and carried out her master’s thesis at Clopath’s Lab. In 2021 she joined the Perea lab at the Cajal Institute (CSIC) as a research assistant, where she worked on in vivo electrophysiology. Since 09/2022, she is a PhD student at the Computational Neuroscience Unit at the CRM working on spatiotemporal stimulus integration in perceptual decision making.

Miguel Donderis

Research Assistant


Miguel graduated in Physics and Mathematics at the Autonomous University of Barcelona in 2022 and currently he’s studying the MsC in Advanced Mathematics and Mathematical Engineering at the Universitat Politècnica de Catalunya. He investigates neural network mechanisms underlying decision making and continuous stimulus estimation.

Sara Ibañez 

Postdoctoral Researcher

Sara joined our group as a senior postdoctoral fellow in February 2021 to work on models of age-related changes of working memory. Previously, she worked as a junior postdoc at the Franklin & Marshall College in Pennsylvania and at the Boston University School of Medicine, in a joint project studying the effect of age-related changes in individual pyramidal neurons in the rhesus monkey on the network dynamics underlying working memory. She did her PhD in Physics at the UPV/EHU.

Nicolás Pollán Hauer

Doctoral Student

He graduated in Physics (BsC) at the University of Oviedo in 2017 and got a MsC in Condensed Matter Physics and Biological Systems at the Autonomous University of Madrid in 2018. In September 2018, he joined the lab with a fellowship from La Caixa Foundation in the Training Programme in Collaborative Mathematical Research. 


Citlalli Vivar

Doctoral Student

Citlalli graduated with an M.Sc in Brain and Cognition from Pompeu Fabra University and a B.A and M.A in Economics from Instituto Tecnológico Autónomo de México. She joined our lab in January 2020 with a predoctoral contract from the Spanish Ministry of Science, Innovation and Universities.


Anna Wilson Ganzabal

Research Assistant

Anna is an Applied Neuroscience master’s student from King’s College London and a graduate from the University of Nottingham with a BSc in Psychology and Cognitive Neuroscience. In November 2022, she joined our lab to study the age-related changes in working memory in rhesus monkeys.

Former lab members

Gabriela Mochol

Gabriela Mochol joined our group in January 2021 as senior postdoctoral fellow at the Centre de Recerca Matemática, Barcelona. She obtained a PhD with specialization in neuroinformatics at the Nencki Institute of Experimental Biology in Warsaw, Poland under the supervision of Daniel Wojcik. She was a junior postdoc in the lab of Jaime de la Rocha  in IDIBAPS in Barcelona and Juan de la Cierva fellow in the lab of Ruben Moreno Bote at UPF Barcelona.

Jose Mari Esnaola

During his PhD (UPF, Barcelona) he studied the spatiotemporal dynamics of large networks of spiking neurons that arise when populations of neurons undergo transient synchronization.  Before that, he graduated in Physics and got a MsC in Mathematical Modeling at UAB, Barcelona. He joined the lab as a PostDoctoral researcher in October 2018 where he has been studying the neural mechanisms underlying perceptual decision making in humans.
