RE-ADVERTISEMENT: Postdoc position in circulating tumor DNA

Updated: about 2 months ago
Job Type: FullTime
Deadline: 11 Apr 2023

The Department of Clinical Medicine, Faculty of Health at Aarhus University invites applications for a position as Postdoc in circulating tumor DNA at the Lindbjerg Group, Department of Molecular Medicine (MOMA), Aarhus University Hospital.

The position is a 3 year full-time position, starting 1 June 2023, or as soon as possible thereafter.

About the research project

The Lindbjerg Group pioneers approaches for non-invasive molecular diagnostics for cancer, primarily based on next-generation sequencing (NGS) of circulating cell-free tumor DNA (ctDNA). Led by Professor Claus Lindbjerg Andersen and a team of experienced translational genomics scientists, the lab studies large collections of plasma and other samples from cancer patients through an extensive portfolio of clinical studies and collaborations. The group directs the Danish National Center for Circulating Tumor DNA Guided Cancer Treatment ( aiming to facilitate the implementation of ctDNA guided cancer management in Denmark. In addition, we are involved in EU consortia with similar goals centered around moving ctDNA into daily clinical use.

The group develops ctDNA detection tools spanning from droplet digital PCR (ddPCR) to genome-wide and targeted, cancer-centered next generation sequencing (NGS) methods. We are working on maturating these methods into clinical use through a range of translational studies aiming at demonstrating their utility. We further explore the biophysical properties of ctDNA to study its origins and interactions. The group is a dynamic mix of molecular biologists, bioinformaticians and clinical fellows providing a unique environment for development and learning in cancer genomics and translational research, with a strong focus on clinical application.

Your job responsibilities

Circulating cell free tumor DNA (ctDNA) has during the last decade emerged as a revolutionizing, non-invasive biomarker for cancer in a range of clinical settings, including early detection, residual disease monitoring and during chemo- and immunotheray treatment. Therefore, new technologies for more sensitive and accurate ctDNA detection is rapidly evolving.

The overall aim of the project is to develop frameworks facilitating a faster and more robust introduction of ctDNA detection into practice-changing, clinical use.

Your primary responsibilities will be focused on leading the Danish National Center for Circulating Tumor DNA Guided Cancer Treatment's efforts to develop and implement a national framework for standardizing ddPCR and NGS based ctDNA detection in clinical settings. In parallel with this, you will be responsible for working with our European collaborators to develop ctDNA reference samples, and use this to evaluate the clinical applicability of ctDNA technologies.

You will work in close collaborations with our department's research biotechnologists, with members of the ctDNA center, as well as with international partners.

Your main tasks will consist of:

  • Developing artificial standard DNA materials that can be used as a common reference set across different ctDNA detection technologies and laboratories.
  • Be responsible for benchmarking of commercial ctDNA technologies including both the laboratory parts and analyzing results.
  • Developing "best practice" guidelines for conduction of ctDNA detection in order to facilitate the use of ctDNA at research and hospital laboratories.
  • Developing and conducting national quality assurance programs for ctDNA detection.
  • Developing a national quality and certification standard for ctDNA detecting.
  • Reporting the results of your work in workshops in the ctDNA center to disseminate ctDNA knowledge and knowhow, as well as in international research papers.
  • Together with a PI, be responsible for a ctDNA guided clinical trial

You will report to Group leader Professor Claus Lindbjerg Andersen.

The ideal candidate
  • Has a Ph.D. in Molecular Biology, Molecular Medicine or equivalent.
  • Has experience with NGS and ddPCR.
  • Has an interest in cancer biology and liquid biopsy.
  • Can plan and perform experiments in the laboratory in a systematic and methodical way.
  • Can do data analyses of large genomics data using programming languages (e.g. bash, Python or R).
  • Is motivated for independent and systematic work, and can take ownership of her/his work, and do the interpretation and presentation of results.
  • Is a team player with good collaborative as well as communicational skills.
  • Can speak and write English.
