Karl Farrow

Karl Farrow, PhD

Group leader

Originally from Toronto, Canada, I pursued my doctoral research with Axel Borst at the Max-Planck Institute of Neurobiology in Munich, Germany. There I focused on dissecting the neural circuits guiding optic flow process in the Blowfly. As a postdoc I worked with Richard H. Masland at Harvard Medical School, then Botond Roska at the FMI in Basel dissecting the neural circuits of the retina that enable each cell-types to encode a different feature of the visual scene.

Lab Manager | Technician

I am born and raised in Leuven, Belgium. I started my professional career at Philip Morris. Here I discovered that my interests are in managing and supporting a laboratory. In 2012 I started to work at Nerf. On the job I accomplished my Felasa certificate and after working for years under the wings of Ilse Eyckmans I got the opportunity to really get to know how a lab needs to work. Nerf offered me a possibility to take it a step further, to help manage the Farrow lab. My interests are what is happening behind the curtains, where does all the data come from and how can we find it.

Norma Kuhn, PhD

Postdoc

I am fascinated by the computations of the brain, how sensory signals are effectively parsed through neural circuits to give the appropriate response. Determining the detailed input-output functions of a neural circuit is my goal. Before I started studying the mysteries of the brain, I did a diploma in physics at the University of Leipzig, Germany, where I looked at how stochastic dynamical systems behave far from equilibrium. Putting theory into practice, I joined the lab of Tim Gollisch at the University Medical Center Göttingen, Germany, for my PhD, where I investigated the encoding of motion in the retina. Here, I found new mechanisms of how the brain can decode small stochastic eye movements from groups of retinal neurons that are sensitive to specific motion directions. The question how the visual information extracted by the retina is used in the rest of the brain, brought me to the lab of Karl Farrow. Here, I look at how the signals from identified retinal neurons are combined along the dendrites of a collicular neuron that triggers freezing responses to an approaching predator. Understanding how neurons combine their thousands of inputs to a single output is, among knowing how they are connected, one of the keys for understanding the brain.

Arnau Sans Dublanc, PhD

Postdoc

I am from Barcelona and started my Neuroscience career during my master’s in biomedical sciences and then Neurosciences at the labs of Lluis Fuenemilla and Carles Sindreu, both at the University of Barcelona. There, I first studied memory generalization processes in humans and later circuits for memory retrieval in mice. In 2016 I started my PhD at Karl Farrow’s lab and developed an approach to study cell-type specific brain-wide networks using optogenetics and functional ultrasound imaging. This allowed me to reveal the downstream networks of the superior colliculus that mediate different innate orienting behaviors. Currently, I am starting to investigate the networks that are naturally driven by visual stimuli known to trigger innate defensive behaviors and the process of habituation to such behaviorally relevant stimuli.

Laura Hanson

Laura Hanson, PhD

Postdoc

I was born and raised on Vancouver Island, Canada where I obtained my BSc in Microbiology and Biochemistry at the University of Victoria. I then completed my PhD in Neuroscience in the lab of Gautam Awatramani where I studied circuitry and mechanisms involved in visual processing in the retina. This research made me curious to understand how the retinal signals are being integrated in higher order visual areas to drive behaviors. I joined the Farrow lab to study this process in the superior colliculus and investigate how visually evoked innate behaviours can be modulated across different life stages.

Gioia De Franceschi

Gioia De Franceschi, PhD

Postdoc 

was born and raised in Italy, and I have always been intrigued by biology and in particular by animal behavior. During my BSc in Molecular Biology at the University of Padua I discovered a passion for the brain, that I pursued with a MSc in Neuroscience at the University of Trieste. There, I joined Davide Zoccolan’s Lab at SISSA to study visual object recognition. I then moved for my PhD to University College London in Sam Solomon’s Lab, where I investigated the functional properties of visual neurons in the mouse superior colliculus and how vision helps mice make instinctive behavioral choices. Fascinated by flexible perception and behavior I decided to join Tania Barkat’s lab at the University of Basel, where I characterized how neuronal responses along the auditory pathway are modulated by behavioral state. I then moved to Santiago Rompani’s Lab at the European Molecular Biology Laboratory to study multisensory integration in the visual thalamus. Wanting to deepen my understanding about how the brain uses sensory information for generating appropriate behaviors, I started a synergistic collaboration with Karl Farrow’s Lab at NERF, where I am currently investigating multisensory integration in the early visual system.

PhD Student - Joint student with Lieve Moons

I was born and raised in Portugal where I obtained a BSc and MSc in Biomedical Sciences. My master’s project was focused on the discovery of biomarkers for the diagnosis of Alzheimer’s disease. After my MSc, I continued this line of work with an internationalization through the Erasmus programme in the Universität of Göttingen (Germany). Since November 2018, I have been working as a PhD student in Farrow lab, in collaboration with Prof Lieve Moons. I am interested to know how we can regenerate axons both after injury and during neurodegenerative diseases. I aim to provide an important basis for a cell specific promotion of neuronal repair.

PhD Student

I grew up in Belgium and completed a MSc in Applied Computer Science and a MSc in Artificial Intelligence at KU Leuven. I was first introduced to neuroscience research when working on automated animal tracking in the lab of Dr. Karl Farrow, as part of my thesis in Artificial Intelligence. After my thesis, I decided to transition towards neuroscience and therefore joined Karl Farrow’s lab as a PhD student in 2019. In the lab, I apply and develop machine learning methods to uncover what visual and behavioral information is encoded along the circuitry underlying visually-evoked defensive behaviors. I am currently focused on finding out what behavioral information passes through the superior colliculus and what role collicular cell types have in encoding that information.

PhD Student

I was born and raised in Italy, where I obtained my BSc in Biotechnology at the University of Trento. Although my fondness for neuroscience began during secondary school, my career in this field started during my MSc in Biophysics, Biochemistry and Biotechnology at the KU Leuven. Here, I carried out my thesis project in the laboratory of Prof. Joris de Wit (VIB), where I aimed to map the proteome of specific synapse types in the mammalian brain to elucidate the role of synapse diversity in circuit organization by using a novel CRISPR-based endogenous tagging approach. My interest in the mechanisms governing neural processing and the relationships that link sensory inputs with specific behaviors led me to join the Farrow lab as a PhD student in May 2021. I am currently investigating how visual information is processed by different regions and cell types of the superior colliculus and disseminated to drive innate behaviors.

MSc student

I was born in Leuven and lived there my entire life. Growing up here means that you see the IMEC tower on a regular basis and as a kid such a large and beautiful building really speaks to your imagination. You hear that real great things are being accomplished there and you are even proud that this facility is in your hometown. This is actually how I still feel. So I’m very happy and motivated to do my thesis there myself and contribute to the research being done at NERF.

I obtained my BSc degree in Biochemistry and Biotechnology at the laboratory of biomolecular discovery & engineering in the research group of Joleen Masschelein at the KU Leuven. Now I’m obtaining my MSc degree from the KU Leuven at the Karl Farrow lab at NERF.
