Postdoc position

Postdoc position - Developing novel ways to control viruses for the targeted infection of cellular systems
100%, Basel, fixed-term

The highly competitive the Bio-Engineering Systems for Therapeutics (BEST) postdoc programme, part of the Next-gen Bioengineers initiative, is operated jointly by the Department of Biosystems Science and Engineering of the ETH Zurich and by the Roche Pharma Research and Early Development (pRED). The programme focuses on development of new tools and methods to resolve existing problems and come up with solutions for future challenges in medical translation and therapeutics.

Project background

Viral vector-based gene therapies are extensively explored in preclinical and clinical development for the treatment of genetic diseases by infecting targeted cells. However, elaborating the target cell specificity of viral vectors, called as tropism, is an ongoing and crucial endeavor in the field of gene therapy. Viral infection is triggered when a virus binds to cell surface receptors with certain thermodynamic and kinetic on/off rates at equilibrium, which could act as a limiting factor to further enhance or optimize viral tropism. In this collaborative project, we explore new ways to adjust this equilibrium so the on/off rates of viral vectors brought in proximity to target cells / tissues / organoids can be controlled to promote viral infection. To reach this goal, we will apply multiparametric approaches to quantify the interaction (on/off rates) of a specific set of viruses with desired regions of cellular systems such as cultured cells, organoids, tissues, and organs. Then, it is thought to characterize the parameters that shift the thermodynamic and kinetic on/off rates and viral tropism. Ultimately, this quantitative approach will open new ways to engineer and control the on/off equilibrium of viral vectors rather than genetically engineering viral vectors by optimizing the transgene cassette or capsid. Finally, we anticipate that this study will open new possibilities to increase transduction efficiency and viral tropism for successful viral gene therapy.
