5 PhD positions in Theoretical Geophysics

The Institute of Geophysics of the Polish Academy of Sciences is the leading scientific centre in Poland in the field of the Earth physics research. The Institute's research programme considers experimental and theoretical studies in scientific disciplines such as seismology, geomagnetism, atmospheric physics, geophysical imaging, lithospheric research, hydrology & hydrodynamics and polar & marine research. The Institute employs about 200 people (including 60 academics) and is a member of major international geophysical bodies.

As a member of the Geoplanet Doctoral School and Environmental Doctoral School, the Institute of Geophysics offers the PhD courses in geophysics. The course lasts 4 years, is conducted in English and ends with a PhD thesis. During the course, the student attends lectures and participates in research under the direction of a supervisor.

Doctoral students can receive, for the duration of their studies, a doctoral scholarship 2100 PLN monthly. The best three candidates from abroad may apply for scholarship 5000 PLN monthly. PhD scholarships paid as part of scientific projects conducted by some supervisors (e.g. National Science Centre of Poland - see below) can reach 5000 PLN monthly (depend on the project).

The Institute of Geophysics seeks applicants
for five doctoral positions
in Theoretical Geophysics and related topics.

1. Cellular automata modelling inter-event time distributions for earthquakes

The PhD scholarship is funded by the National Science Centre of Poland for the project "Mechanistic explanation of a generation of (and deviations from) the universal curve of the Earthquake Recurrence Time Distribution by means of constructions of solvable stochastic cellular automata and their analytical description." The scientific work will include:

  • Generating inter-event time distributions using various versions of Random Domino Automata
  • Numerical and analytical tests of the properties of extensions of Random Domino Automata
  • Comparative tests with real data

The candidate should hold master's degree in exact sciences (preferred physics or mathematics), natural sciences (earth sciences) or technical sciences and a positive result of recruitment for doctoral studies at the Institute of Geophysics of the Polish Academy of Sciences (until the start of work). Requirements for candidates: experience in the field of stochastic processes or statistical physics and modelling of complex systems; basic knowledge of earthquakes; ability to use the Mathematica program in the field of numerical calculations and simulations; good English in speech and writing; strong motivation for scientific work and willingness to develop knowledge in the field of theoretical geophysics.

2. Modelling of non-Markovian time series by the modified nonlinear Langevin equation

In the framework of the proposed subject, the PhD student will be involved in:

  • Examination of the time series recorded in monitoring geophysical phenomena using different modern statistical methods.
  • Modelling of the phenomena by the nonlinear Langevin equation. It must be appropriately modified to describe non-Markovian processes.
  • Developing the appropriate method of reconstruction of the modified Langevin equation based on time series data.
  • Testing the procedure on synthetic data.
  • Application of the procedure to selected geophysical phenomena.

Requirements for candidates: The candidate should hold a master's degree in mathematics, physics, geophysics, or equivalent science discipline. Knowledge of the basics of probability theory and statistics and the basics of differential and integral calculus. Experience in computer programming is welcome. Good command of speaking, reading and writing English. Having research track record of publications, conference presentations, and participation in scientific projects will be welcome candidate's advantage.

3. The goal of the proposed research is to apply called Time Reversal method for inversion seismic moment tensor for mining induced seismic data.

The goal of the proposed research is to apply, so called, time reversal method for inversion seismic moment tensor for mining induced seismic data. Seismological research, no matter if concentrated on physics of earthquakes or the Earth structure is always based on seismic waves recorded at Earth surface or near it (deep mines). In consequence seismological analysis always have a form of inverse problems. The thought quantities can never be measured directly their values, relations, etc. have to be inferred from existing seismic records. For this reason it is extremely important to develop modern numerical methods for an efficient processing seismic data.

Requirements for candidates: should graduate in physics or applied mathematics, informatics, or geology and demonstrate at least passive knowledge of English. Experience in programing in at least one of the programming language: C, Python, Matlab, R, Julia Bash, Tcsh is required. Knowledge elementary numerical methods is welcome.

4. Analysis of microscopic rupture processes and their relation to natural/induced seismic events using advance numerical simulations. These simulations are planned to be based on the modern Discrete Element Method approach

Within the PhD position we propose the analysis of microscopic rupture processes and their relation to natural/induced seismic events using advance numerical simulations. These simulations are planned to be based on the modern Discrete Element Method approach. In spite of an enormous progress in study of the earthquake source processes in recent years our understanding of physical processes leading and occurring in earthquake foci are still not satisfactory. There are many reasons for this situation among which nonlinearity of occurring processes and lack of scale separation are the most important. This lack of scale separation between processes at micro-scales (tips of cracks, micro-cracking, to name a few) and final, large scale visible earthquake effects (ruptures of faults of tens to hundreds kilometres) is the largest problem on contemporary seismology of earthquake sources.

Requirements for candidates: should graduate in physics or applied mathematics, informatics, or geology and demonstrate at least passive knowledge of English. Experience in programing in at least one of the programming language: C, Python, Matlab, R, Julia Bash, Tcsh is required. Knowledge elementary numerical methods is welcome.

5. Seismicity of subduction zones: hierarchical asperity model perspective

Asperity fault model is a general, key concept used to understand seismicity in subduction zones. In this context, our PhD studies are focused on three main tasks:

  1. to reveal hierarchical asperity structure from real seismicity data,
  2. to model earthquake occurrence and seismicity by computer simulations,
  3. to formulate earthquake forecasting problem.

To this end, some concepts of advanced mathematics and physics should be applied.

The ideal candidate should hold master's degree in exact sciences, preferred, physics or mathematics, possibly geophysics or/and seismology. Good programming and numerical methods skills. Fluent English in speech and writing. Strong motivation for scientific work and passion for theoretical researches.
