Abnormalities in sensorimotor integration in mTORopathies – underlying mechanisms and potential treatments | 1,0 fte

About this position

The candidate will study the mechanisms underlying sensorimotor integration problems in mTORopathies, aiming to identify possible treatments, as described in more detail below:

Problem: The mechanistic target of rapamycin (mTOR) pathway is a highly complex and conserved signaling cascade involved in biomass synthesis, growth and cell proliferation. Specifically, during brain development, it has been proposed that a tight regulation of mTOR signaling is required for sustaining cell cycle length and re-entry, defining pluripotency status and triggering differentiation. Therefore, mutations along this pathway frequently lead to complex monogenic neurodevelopmental disorders (also known as mTORopathies), characterized by vast and heterogeneous phenotypes that can include increased prevalence of immunodeficiencies and malignancies, as well as megalencephaly, epilepsy, intellectual disability and autism spectrum disorder. However, there are currently only a handful of treatments available that address these neurological symptoms, all with significant adverse effects.

Solution: There are currently no biomarkers that can predict the level of intellectual disability or the severity of the ASD deficits in patients with mTORopathies. Interestingly, new insights suggest that sensorimotor network deficits, which reflect underlying brain dysfunction, have a high predictive value for determining neurodevelopmental phenotypes. People with ASD, for example, often present with sensorimotor deficits, which could be easily measured and potentially used as a marker for early diagnosis. Thus, the validation and establishment of new sensorimotor tools that enable a quicker and objective identification of neuropsychiatric phenotypes is critical.

Plan: In this project, the PhD student will investigate, through in vivo approaches and cell cultures, the cascade of events in mouse models of human mTOR-pathway disorders that lead from specific mutations to sensorimotor deficits. The resulting understanding of the mechanisms underlying sensorimotor deficits will be used to then the ability of potential treatments to alleviate the deficits.

Approaches: This work will utilize electrophysiological recordings, microscopy and imaging techniques, combined with various behavioral tasks to analyses sensorimotor (in)abilities. The student will then test different intervention methods, including ultrasound-triggerable drug delivery systems developed by the consortium. The treatment methods will be tested first in organotypical slices and human iPSC cerebellar cultures before applying them to mouse models.


We are looking for a highly motivated and goal-oriented researcher with a M.Sc. degree in nanobiology, neuroscience, cell biology, biophysics, biomedical sciences, or related field. The ideal candidate has a background in molecular techniques (qPCR, Western blots etc.), behavioral techniques and electrophysiology, and is interested in learning how to use neuronal cell cultures to answer neurobiological questions in health and disease. The candidate should be fluent in English, have basic knowledge of at least one coding language (Pyton or MATLAB) and be motivated to work in an ambitious and collaborative research team.

About this Flagship

Within Convergence Health & Technology we work on groundbreaking research and innovation, bundled in 10 internationally leading research flagships. These are aimed at major breakthroughs in the fields of health and science.

This project is part of the Convergence program Integrative Neuromedicine, a large-scale collaborative effort from Erasmus University, Erasmus Medical Center and Delft University of Technology to develop integrated biological and computational models of the human brain. The PhD student will be part of the Badura and Schonewille labs, but interact regularly with the other project members for different aspects of the project.

To achieve this goal, our flagship team includes fundamental scientists, engineers, philosophers, psychologists, and clinicians across the three different institutions to converge towards a personalized integrative medicine approach. We want to combine data from all scales, from birth to deathbed, to understand the evolution of neurological disorders. We will start with identifying common biomarkers involved in these disorders. Our research will enable early diagnosis and improve potential treatments over time. Furthermore, we will show how new technology can be developed and used to achieve medically effective personalized treatment, while providing a comfortable and satisfactory experience from the individual’s perspective.

Our flagship project’s effectiveness, cohesiveness, and sustainability lie in the complementary ingenuity of interdisciplinary team members, our extensive network of academic and industrial partners, and the multiple sponsors seeking groundbreaking research. Ultimately, we will establish a pipeline that eases the transition from the bench to bedside through various breakthroughs to improve the subjects’ quality of care and quality of life.
