We are seeking an enthusiastic new member of our team who will use newly acquired geophysical data to resolve the physical properties of subduction zones to improve our knowledge of how they deform and slip in earthquakes. The successful candidate will use cutting-edge 3D full-waveform inversion codes to produce high-resolution physical property models (including P-wave velocity) of the Hikurangi subduction zone, New Zealand, in a region where slow slip events occur. Slow slip events are an enigmatic type of seismic behaviour that involve as much slip as a magnitude 7 earthquake but take place over a number of weeks and do not cause shaking. Their generation mechanisms are still poorly understood and the successful Research Associate will perform important new research to resolve the geophysical environment of slow slip.
The Research Associate will have the opportunity to work with new 3D multichannel seismic, ocean bottom seismometer and land-based seismometer data that was collected in 2017-2018 as part of the NZ3D project (https://nz3dfwi.weebly.com/home.html). The Research Associate will join a large international community of scientists working on this problem and will join meetings with national and international collaborators via video conference, meetings at conferences and visits to other institutions.
Duties and responsibilities
As well as their research responsibilities the Research Associate will also become an important member of a new research group at Imperial College called SMILE (Subduction Margin Imaging with Large Experiments). This will involve assisting with the supervision of PhD students, Masters and Undergraduate student projects and helping to develop the identity of the group.
The PDRA will be expected to present their research at national and international conferences, publish articles in peer-reviewed international journals and conduct societal engagement activities both in the UK and New Zealand. This Leverhulme Postdoctoral Research Associate in Geophysics position would suit a numerate geophysicist or computational scientist with an interest in science that matters to society.
- You will be involved in a project that aims to resolve the P-wave velocity and other physical properties at a high-resolution across the Hikurangi subduction zone, New Zealand.
- The project will require you to apply 3D full-waveform inversion codes developed at Impeial College to a large active-source seismic dataset. You will be responsible for running inversions on high-performance computers, quality controlling results and interpreting the physical property models to better understand slow slip processes.
- You will be involved in helping to supervise PhD students also working on the project and be an active part of a large international group working on these data.
- You must have a good undergraduate degree or Masters degree in a subject relevant to the proposed research. This could include subjects such as Geophysics, Earth Science or Computational Science.
- You should hold, or should expect to obtain before appointment, a PhD or equivalent doctoral qualification in a relevant area of computational geophysics.
- Applicants should be familiar with the methods and theory of full-waveform inversion and associated techniques. Prior experience working with 2D or 3D Full waveform inversion codes would be considered an advantage.
- Applicants should have a demonstrated experience of applying advanced numerical computer codes to real field seismic data
- Some experience with at least two of the following areas is required:
- Controlled source seismic data processing
- Passive source seismic data analysis
- Travel-time tomography
- Geophysical data inversion
- Experience working with high-performance computer systems
- An interest in seismic hazard and subduction tectonics
This is a fixed term position for 33 months from the date employment commences. Ideally, we are looking for a candidate who could take up the position from October 2019, although there is some flexibility.
*Candidates who have not yet been officially awarded their PhD will be appointed as a Research Assistant within the salary range £34,397 - £37,486 per annum.
