Billy Andrews (from University of Strathclyde)

Billy Andrews (From January 2017)

Billy Andrews is a second-year PhD student in the Department of Civil and Environmental Engineering, University of Strathclyde. His research focuses on the Internal structure and Geomechanics of faults cutting coal-bearing stratigraphy. Prior to starting his PhD Billy completed an undergraduate in Geological Sciences (BSc) at the University of Leeds, which included being awarded prizes for the Best undergraduate mapping project, being an outstanding student in the faculty and winning the Dave Johnston Mapping Prize at TSG 2017. His research uses a combination of field and micro-structural analysis to better understand the behaviour of faults both within coal and the surrounding lithologies. This work has applications to a number of sectors including mine safety, carbon capture and storage, geothermal energy and conventional oil and gas.

Ri Cao (from Oxford University)

Ri Cao (From January 2018)

Ri Cao is a first-year DPhil student in Department of Earth Science, University of Oxford. His DPhil explores the visco-elasticity of upper mantle materials utilising high-resolution techniques (SEM, HR-EBSD and high-temperature uni-axial creep test). Viscoelasticity is definitely significant in geodynamic scenarios such as the glacial isostatic adjustment, seismic wave propagation, and postseismic relaxation. For long time period, the mantle mass redistribution along with the continuous viscoelastic response of the solid Earth to the deglaciation since the LGM (Last Glacier Maximum), or the GIA (Glacial Isostatic Adjustment) process, has been deforming the ocean floor and changing the associated gravity, leading to the variation of the global mean sea level. The nonlinear viscoelasticity can also be utilized to explain the phenomena of tidal dissipation in rocky planetary bodies such as Io or Europa. Compressional oscillation test will be utilized to squeeze the sample in order to create dislocation (screw and edge dislocation), of which the number of dislocation will be larger than that measured by torsional oscillation test. Ri graduating from UCL with a master degree in Geoscience with merit. Ri’s master project looked at reproducing the structure and properties of a new mineral HAPY (hydrous aluminum-bearing pyroxene) from first principal utilizing VASP. HAPY is a new mineral recently found in the upper mantle area, which can transport water to more than 150km depth, triggering the formation of the basaltic magma. Elastic constant has been calculated in order to get the seismic velocities (Vp, Vs, and Vd), and then compared with stable mantle phases at the same temperature and pressure conditions in order to determine whether this mineral could be seismically visible or not.

Izzy Edmundson (From January 2018)

Izzy Edmundson is in her first year of PhD studies at the University of Bergen in Norway. She is not new to Norway since she previously worked as a graduate geoscientist for two years in Stavanger. She studied at Royal Holloway, University of London for her MSc in Petroleum Geoscience. She made this switch to geology in 2013 having previously studied geography for her undergraduate studies at Newnham College, University of Cambridge.  Her research focuses on structural controls on fluid flow in the SW Barents Sea. The research combines analysis of subsurface data and structural modelling techniques, with field work and laboratory tests on fault rocks samples, she hopes from Svalbard! This area of research has relevance not only for the petroleum industry but also, geothermal, carbon storage and construction. Aside from geology, her passions include road cycling, skiing and horse-riding having previously worked as a jockey in the UK.

Responsibilities

There two postgrad reps on the TSG committee. They represent the interests of postgraduate researchers in the TSG community, highlighting issues that TSG can support. Their main day to day role is to promote TSG activities by leading the maintenance of the website, Facebook group, Twitter and LinkedIn pages.
