PhD student position in applied geophysics on three-dimensional inverse modelling of controlled-source electromagnetic data

The Department of Earth Sciences at Uppsala University will start coordinating and conducting research within a Europe-wide H2020 Research-Innovation-Action (RIA) project related to new exploration technologies for mineral resources. While the focus will be on geophysical instruments and methods (covering a wide range from electromagnetic to seismic methods), there are also aspects related to data (geological and geochemical) and target generations. The department is the largest and broadest as such in Sweden and includes Geophysics, Geology, Palaeontology, Hydrology, Meteorology and Natural resources programs. It is located next to the Geological Survey of Sweden (SGU) allowing a great level of interaction with researchers from SGU.

The advertised PhD student position in applied geophysics on three-dimensional inverse modelling of controlled-source electromagnetic data is open in the Geophysics Programme of the Department of Earth Sciences. This research project will focus on the further development of a three-dimensional finite-difference modelling algorithm for controlled-source electromagnetic data to inversion including field measurements and application of the modelling algorithm to the data collected as part of  the H2020 project.

Duties/Project description: The PhD project aims at developing a general 3D inversion code for controlled-source electromagnetic (CSEM) data that can be applied to frequency- and time-domain measurements performed in the air, on the Earth’s surface and in boreholes. This code will be based on an existing CSEM finite-difference forward modelling code developed by a project partner at Aarhus University, Denmark, that is branched into frequency- and time-domain parts. The development of the inversion code will be performed jointly with Aarhus University. However, the focus of development at Uppsala University will be on 3D inversion of surface and borehole CSEM measurements, whereas Aarhus University will focus on inverse modelling of airborne CSEM data. As compared to other codes, the new 3D inversion code is envisaged to have advantages in terms of its general applicability and the possibility to perform joint inversions of airborne, ground-based and borehole frequency- and time-domain CSEM measurements. It will contribute to taking industry practice for inversion of airborne measurements and ground-based and borehole measurements from laterally constrained 1D inversion and thin-sheet modelling, respectively, to 3D inversion. Thus, it is expected to lead to more comprehensive models than currently available.

The successful candidate will be given ample opportunity to develop skills in electromagnetic field theory, numerical methods such as finite-difference and finite-element methods, numerical linear algebra and gradient-based inversion techniques (e.g. non-linear conjugate gradient methods or quasi-Newton methods), parallel programming, acquisition and processing of electromagnetic field data and interpretation of multi-dimensional resistivity models inverted from electromagnetic data.

Postdoctoral Fellow at Virginia Tech

The Department of Geosciences at Virginia Tech invites applicants for a postdoctoral position in near-surface geophysics. The successful candidate will conduct research on the “critical zone,” the upper ~100 m beneath Earth’s surface, using a combination of near-surface geophysical methods (seismic refraction, electromagnetic, and DC resistivity, among others). The successful candidate will be expected to conduct original research leading to publications, participate in geophysical field work, and contribute positively as a member of an interdisciplinary team.

The successful candidate must have a Ph.D. in geophysics or a closely related field at the time of appointment. Demonstrated competence in near-surface geophysical instrumentation and methods (seismic, electrical, and/or electromagnetic) is required. In addition, evidence of research productivity in the form of peer-reviewed journal publications is required. Willingness to participate in geophysical field work in support of team goals is required.

Preferred qualifications include 1) demonstrated capacity to work productively in collaborative and interdisciplinary teams; 2) knowledge of critical zone geophysics; 3) demonstrated history of applying geophysical techniques to problems in hydrology, chemical weathering or surface processes at the watershed or hill-slope scale; and 4) experience in analyzing airborne geophysical (electromagnetic) data.

Qualified applicants must electronically submit online application, cover letter, resume/curriculum vitae, Research Statement and a list of 3 professional references to jobs.vt.edu. Apply to posting #SR0170340. Applicant screening will continue until the position is filled. Virginia Tech is committed to building a culturally diverse faculty and strongly encourages applications from women and minorities.
