You will join a UvA team, collaborating with a nationwide group of scientists, that aims to unravel neural mechanisms of vision and multisensory integration. One of the major questions in the neuroscience of conscious vision is how the visual cortex integrates photic information with other modalities, including audition and motor activity. The primary visual cortex not only processes photic information, but also harbours neuronal ensembles responding to auditory stimuli and motor movement. We will visualize the physiological activity of such ensembles and non-visual cortical areas using 2-photon imaging. By applying optogenetic techniques and closed-loop interface technology, we will investigate which of these ensembles play a causal role in visual and multisensory decision-making. Results will be embedded in an integrated framework involving computational modelling and theoretical neuroscience, and will help assess a specific theory of consciousness (neurorepresentationalism).

Tasks and responsibilities:

• complete and defend a PhD thesis within the official appointment duration of four years;

• perform a series of experiments targeting 2-photon imaging and optogenetic manipulation of cortical areas during a task requiring multisensory change detection, with additional work in multi-area electrophysiology (with e.g. Neuropixels probes), histology and widefield calcium imaging;
• interpret findings in the context of a theoretical framework on consciousness, postulating that interactions between sensory modalities in cortex subserve multisensory integration and segregation;
• perform advanced analysis of acquired experimental data and publish the results. You will have access to top notch facilities for performing experiments, behavioral training and data analysis. You will collaborate with a data analyst and other group members in these activities. Animal facilities, as well as biotechnical and ICT support, are available;
• interact with local researchers, colleagues in the DBI2 Gravitation Consortium and international institutions, which will be conducive to the success of the project;
• assist in practical activities associated with academic courses and internships (Msc/Bachelor level).

You are passionate about science and have a particular interest in brain mechanisms of multisensory processing, visual perception and consciousness. You enjoy performing experimental lab work in the field of systems neuroscience, but are also enthusiastic about data analysis and use of computational tools. You have a creative mind and look forward to working on cutting-edge scientific questions. Finally, you are a team player and a nice colleague who enjoys being part of an interdisciplinary team. 

Your experience and profile

• a Msc degree, preferably in neuroscience, experimental neurophysiology or related field;
• significant experience with in vivo optogenetics, animal behaviour, electrophysiology (silicon probes or similar) and/or neuronal imaging with cellular resolution, and surgical techniques;
• significant experience in animal training and behaviour;
• experience in, or at least affinity with, computational neuroscience and/or theory of consciousness;
• experience in computer programming (Matlab, Python) and neural data analysis;
• FELASA B (article 9) license for animal experiments is considered an advantage;
• fluency in English, both written and spoken;
• good analytical, writing and presenting skills.

A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). The preferred starting date is 1 October, 2025. This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.

Based on a full-time appointment (38 hours per week) the gross monthly salary will range from €2,901 in the first year to €3,707 (scale P) in the last year. This does not include 8% holiday allowance and 8,3% year-end allowance. The UFO profile PhD candidate applicable. The Collective Labour Agreement of Universities of the Netherlands is applicable.
