Job description

Humans and animals can successfully detect sounds and react to vocalisations in the middle of busy acoustic environments, e.g. a busy street or a party. Current algorithms are not yet achieving the same level of performance. The brain is thought to use expectations and predictions to overcome this challenge. What are the underlying mechanisms and circuits that enable this performance? Can we translate these algorithms to technical applications, such as hearing aids or speech recognition in smart phones?

In this PhD project you will address these questions on a fundamental level, recording many neurons simultaneously from the auditory cortex of mice while they perceive and react to sounds. You will be using a cutting-edge two-photon microscope for this purpose, which allows recording from up to 1000s of neurons in each mouse. Next, you will analyse the resulting data to discover the mechanisms that integrate expectations/predictions with current acoustic information and in this way improve the signal-to-noise ratio, against a background sound. A central step in this analysis will be to refine our processing pipeline to allow for more complex and sophisticated experiments. For this purpose, and to guarantee a swift start, you will work closely with a second PhD candidate who has already acquired expertise in all practical aspects of the project. The results of this PhD project have the potential to generalise to other domains of neuroscience and generalise to a new theory of predictive coding, based on the actual underlying neural circuits and computations. You will have a teaching load of up to 10%.

Specifications

Radboud University

Requirements

  • You hold a Master's degree in physics, biology, artificial Intelligence, electrical engineering or a related field.
  • You have excellent analytical skills, particularly in data analysis and programming.
  • You are highly motivated and have a dedicated work attitude.
  • You have a keen interest in pursuing a scientific career.
  • You have a high degree of intrinsic motivation to understand the principles of neural processing.

Conditions of employment

Fixed-term contract: you will be appointed for an initial period of 18 months, after which your performance will be evaluated. If the evaluation is positive, the contract will be extended by 2.5 years (4 year contract).

  • Employment for 1.0 FTE.
  • The gross monthly salary amounts to €2,434 based on a 38-hour working week, and will increase to €3,111 in the fourth year (salary scale P).
  • You will receive 8% holiday allowance and 8.3% end-of-year bonus.
  • You will be appointed for an initial period of 18 months, after which your performance will be evaluated. If the evaluation is positive, the contract will be extended by 2.5 years (4 year contract).
  • You will be able to use our Dual Career and Family Care Services. Our Dual Career and Family Care Officer can assist you with family-related support, help your partner or spouse prepare for the local labour market, provide customized support in their search for employment  and help your family settle in Nijmegen.
  • Working for us means getting extra days off. In case of full-time employment, you can choose between 29 or 41 days of annual leave instead of the legally allotted 20.
Additional employment conditions Work and science require good employment practices. This is reflected in Radboud University's primary and secondary employment conditions. You can make arrangements for the best possible work-life balance with flexible working hours, various leave arrangements and working from home. You are also able to compose part of your employment conditions yourself, for example, exchange income for extra leave days and receive a reimbursement for your sports subscription. And of course, we offer a good pension plan. You are given plenty of room and responsibility to develop your talents and realise your ambitions. Therefore, we provide various training and development schemes.

Employer

You will join Dr Englitz's team of PhD candidates at the Computational Neuroscience Lab. One of the main interests in the lab is to understand how the brain forms predictions and uses them to optimise decision making. We specialise in advanced analysis of cutting-edge data sets from our auditory physiology facilities, which record neural population activity electrically and optically (widefield and 2P imaging) from the auditory cortices while our mice are listening and reacting to complex sounds. To this end, we use chronically implanted electrode arrays and two-photon optical imaging. Our lab is part of Radboud University’s Donders Institute for Brain, Cognition and Behaviour, a world-class neuroscience institute with state-of-the-art facilities for both human and animal research.
