Repeated head impacts can lead to brain damage that manifests decades later as Alzheimer's, Parkinson's and motor neuron disease. However, the underlying mechanisms are unknown. Are you passionate about uncovering what happens to the brain during impact, subsequent injury, and how the injury evolves, or resolves, afterwards? Then we are inviting you to join our interdisciplinary research teams to explore the long-term effects of repetitive traumatic brain injury (rTBI) in both humans and mouse models.

This PhD position offers you the opportunity to work at the crossroads of (translational) neuroscience and applied physics and biomechanics, contributing to a project with major implications for health prevention in groups at high-risk of TBI, such as athletes and military personnel.
The project aims to (1) differentiate the mechanical response of the head and brain between focal and diffuse loads, (2) determine the molecular and cellular changes in animal models of rTBI and how rTBI affects behaviour and cognition, and (3) translate these findings from animal models to humans.

This project is a collaboration between the Swammerdam Institute or Life Sciences (SILS), University of Amsterdam (UvA), and the Netherlands Organisation for Applied Scientific Research (TNO). Part of this project will be carried out at TNO The Hague location Ypenburg at the department of Personal Protection and Explosive Safety. The department is part of the TNO unit Defence, Safety & Security.
This project is a follow up of our previous published work on traumatic brain injury:

https://www.nature.com/articles/s41590-022-01208-z
As a PhD candidate in our group, you will study and model the biomechanical chain of events following (blast) impacts on the brain, as well as the long-lasting molecular and structural changes inside the brain, and their effects on behavior and cognition. Translational aspects from animal models to humans and vice versa will be a focus. You will also investigate the predictive value of potential biomarkers for brain structural changes and effects.
Besides lab experiments, you will be using your technical skills to simulate impacts and loads from blasts to the brain using numerical models. You will employ cutting-edge modelling and neurobiological techniques, behavioral animal tests, advanced analytical methods, while collaborating with laboratory scientists, and modelling and data specialists between the TNO and UvA-SILS labs.
Tasks and responsibilities:
You will get the opportunity to:
Your experience and profile:
You are dedicated, accurate, stress-resistant, a pleasant colleague, well organized and prepared to, and capable of working at 2 different locations.
We offer 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 as soon as possible. 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 €3.059 in the first year to €3.881 (scale P) in the last year. This does not include 8% holiday allowance and 8,3% year-end allowance. The UFO profile PhD candidate is applicable. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. The Collective Labour Agreement of Universities of the Netherlands is applicable.

The Faculty of Science has a student body of around 8,000, as well as 1,800 members of staff working in education, research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works, be it elementary particles, the birth of the universe or the functioning of the brain. The position is located within the team of Dr. Carlos Fitzsimons (https://www.fitzsimonslab.eu), part of the Brain Plasticity group of the Swammerdam institute of the Faculty of Science.
The Swammerdam Institute for Life Sciences (SILS) is located at the vibrant Amsterdam Science Park. SILS is one of eight institutes of the University of Amsterdam's Faculty of Science (FNWI). With around 240 employees, SILS carries out internationally high-quality life science research and provides education within various university programs. Research is also carried out in close cooperation with the medical, biotech, chemical, flavor, food & agricultural, and high-tech industries, and revolves around 4 main themes, Cell & Systems biology, Neurosciences, Microbiology and Green Life Sciences.
Within the Brain Plasticity group of SILS we study how our brain adapts to changes in an (often challenging) environment. We try to understand how plasticity is 'programmed', and how external factors like (early life) stress, nutrition, drugs, exercise or enrichment) can modify plasticity, and what role it plays in cognition and disorders, such as depression and dementia.
Your work will take place partially at the Personal Protection Team of the research group Personal Protection and Explosion Safety at TNO Defence, Safety and Security. This group works on the protection of people against explosions and head impact, ensuring worker safety for military and safety personnel.
