Do you want to contribute to a future where we can potentially understand diseases in the human brain by measuring the tiny magnetic fields created by neurons in the brain? At DTU Energy our research is targeting exactly this, and we are looking for a new PhD student to numerically aid our team in the design of biomagnetometers.

It is possible to get a deeper understanding of how the brain functions in a non-invasive way through sensing the tiny magnetic fields produced by neuronal currents. Today, this need is primarily met by quantum sensors that must be operated at cryogenic temperatures, which greatly increases the complexity and cost of making such measurements. Therefore, research on alternative methods to detect tiny magnetic fields are a top priority.

In a large Novo Nordisk Foundation sponsored project called BIO-MAG, we aim to create magnetic sensors with subpicotesla sensitivity and use these sensors to map neuron activity at room-temperature. As part of this large project, we are looking for a PhD-student to help us design such sensors using numerical modeling. Using finite element modelling techniques we will study the interplay between material properties and the design of the sensor, which your fellow PhD colleagues will then fabricate and test in the lab.

You will model how the magnetic field changes the current flow in a sensor depending on the material properties and the geometric design of the sensor. The questions we are trying to answer are the following:

  • Which materials should we use to design the sensor?
  • What is the ideal design of the sensor for detecting subpicotesla magnetic fields?
  • Can we control the trajectory of the current in magnetic fields?
  • Can we form automated or machine learning-based routines to answer the above questions?

You will work in close collaboration with PhD-students at DTU Physics and University of Copenhagen, which will realize your designs in the lab, provide experimental input to your modelling and ultimately use the sensors to detect the activity in live neurons in real-time. You will also have the opportunity to carry out measurements of magnetic properties yourself, if you so desire.

Qualified applicants must have:

  • A strong drive to move the frontiers of science.
  • Masters degree (120 ECTS points) in physics, astronomy, mathematics, engineering, chemistry or similar.
  • Experience with electromagnetism as gained e.g. from a standard physics curriculum course.
  • Experience with numerical modelling techniques (ideally finite element modelling) and programming (e.g. Matlab or Python)
  • Ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamic group.
  • Good communication skills in English, both written and spoken.
