Matteo Demurtas

“Hi everyone, my name is Matteo Demurtas and I am very happy to join the Department of Earth Science as a Postdoctoral Fellow working with Prof. Atle Rotevatn on deformation and fluid-flow of basin bounding fault systems in rifts, with main focus on the exposed fault systems in NE Greenland.

Previously to coming to Bergen, I have completed my Bachelor, Master and PhD degrees at the University of Padova (Italy) under the joint supervision of Prof. Giulio Di Toro, Dr. Michele Fondriest and Dr. Steven Smith (University of Otago, New Zealand). After my PhD, I spent 6 months at the University of Otago (New Zeland) working on the application of transmission Kikuchi diffraction (TKD) analysis on geological materials, and finally two years as a Postdoctoral Fellow at the University of Oslo (under the supervision of Prof. Karen Mair) working on discrete element numerical models of granular deformation.

My research background is interdisciplinary, spanning the fields of structural geology, tectonophysics, experimental rock deformation, and numerical modelling of grain-scale deformation. My main research interests include fault zone structural complexity and its effect on earthquake mechanics, fault zone mechanical and hydraulic properties, rheology and deformation mechanisms of nanogranular aggregates, seismically-induced deformation mechanisms in soft sediments, force and stress evolution in granular materials.

My research is conducted with a multidisciplinary approach that includes (i) field studies of fault zones exhumed from different crustal depths, (ii) rock deformation experiments aimed at investigating the mechanical properties of fault zone rocks, (iii) detailed microstructural and microanalytical analysis of natural and experimental faults to uncover the deformation processes active during deformation, and (iv) numerical modelling to inform and quantify field and experimental observations.” You will find Matteo in room no 2152A.

Flavia Boscolo-Galazzo

“I am Flavia Boscolo-Galazzo, I am Italian and I was previously a postdoctoral researcher at Cardiff University.

At UiB, I am a postdoc in Nele Meckler’s lab – Quaternary Geology and Paleoclimate group. I will be working on reconstructing Southern Ocean deep and intermediate water temperatures using ocean sediments dating back to around 30 million years ago, when the Antarctic ice-sheet had only recently formed and was highly unstable. I am a micropaleontologist specializing in benthic and planktonic foraminifera. I am interested in using foraminiferal fossil shells chemistry to reconstruct past climates and ocean biogeochemical cycles, and to investigate foraminiferal biogeography and macroecology in connection with past climate changes.

Here’s a link to the latest research project I have been working on:”

Ingvild Aarrestad

“Hello everyone! My name is Ingvild Aarrestad and I recently started a PhD-project in hydrothermal fluid-rock interactions at the K.G. Jebsen Centre for Deep-Sea Research at the department. The PhD is for 4-years and is supervised by Andreas Beinlich. Both my bachelor’s degree (2015-2018) and master’s degree (2018-2020) was achieved at the University of Bergen. I have only spent one semester away from UiB since I started my education five years ago; I spent a semester at the University of Southampton in the UK during the final semester of my bachelor. During my master’s degree I was a part of the “Geochemistry and Geobiology” research group, and my thesis was focused around stable isotope and environmental geochemistry. The project used stable copper isotope analysis of natural surface water samples collected around the closed copper mines in Røros and Løkken and was supervised by Desiree Roerdink. My master thesis was finished in June 2020.

The main goal of my PhD project is to identify and quantify important feedback mechanisms during hydrothermal alteration of the oceanic lithosphere. Rates of serpentinization have predominantly been constrained by the use of pure olivine. However, common oceanic lithosphere can contain >45% pyroxenes. The initial part of the project therefore aims to identify and quantify the feedback mechanisms that appears due to the presence of both pyroxene and olivine during serpentinization. The PhD follows an integrated approach of hydrothermal experiments, collecting natural samples as well as field observations. The experimental data will hopefully give us the opportunity to extract kinetic parameters that can be used in thermodynamical modelling. I look forward to start experimenting and analyzing the experiment outcomes, and I look forward to another four years at UiB GEO.” You will find Ingvild in room 4140. Welcome to GEO 🙂

Leonardo Muniz Pichel

“Hi everyone, my name is Leonardo (Leo) Pichel and I’ve just started a Postdoctoral Fellowship at UiB working with 2D/3D Numerical Forward Modelling of the Brazilian Campos and Santos Rifted Margins. I’ve been here at the department before, in 2018, for a 3-month VISTA visiting position working with Rob Gawthorpe and I am delighted and super excited to be back to the department and to this amazing city, as well as to rencounter some old friends!  

I am a structural geologist and my research combines seismic interpretation, structural restoration and numerical and physical modelling to investigate the interplay between rifting, salt tectonics and sedimentation. I have a PhD in Earth Sciences by the University of Manchester, in which I studied different aspects of regional salt tectonics and depocentre evolution along Atlantic margins, such as West Africa and Brazil. More recently, I’ve been working as a Postdoctoral Research Associate at the Imperial College of London, analysing regional salt tectonics and its interplay with rifting and breakup architecture along the Santos and Campos Basins, Brazil as well as local salt deformation and minibasin evolution in the North Sea and Precaspian. 

I am also the founder and co-leader of the AAPG Salt Basins Technical Group where we organise bi-weekly webinars, courses and mentoring for ECRs. If you´re interested in participating or presenting you research in our webinars, just drop me a message 😉 

You can also find me in the office 2144 so feel free to pop by for a chat.  Leo” – Welcome back! 🙂

Violeth Swai

“Hi! My name is Violeth Swai from Tanzania. I have just started a PhD in Quaternary geology and paleoclimate under the SOUTHSPHERE (Past behavior of the Southern Ocean`s atmosphere and cryosphere) project. The project’s goal is to use the past as a reference to understand the globally significant behaviour of Southern Ocean atmospheric climate change on human-relevant timescales by integrating emerging sedimentological, geochemical, and glacier modelling techniques in a fundamentally new methodological approach.

My PhD focuses on the reconstruction of Holocene glacial variability of sub-Antarctic Kerguelen Archipelago by using glacier-fed lake sediments. My supervisors are Professor Jostein Bakke, Dr Willem Van Der Bilt (Department of Earth Science, UiB) and Dr Fabien Arnaud (Université Savoie Mont Blanc).

I am very happy and excited to be part of GEO’s team. Kindly find me in office 3138, 3rd floor. I look forward to working and collaborating with you.” Welcome to GEO 🙂

Samuel Pereira

Hei Geo! My name is Samuel Pereira and I have just started my PhD in ‘Hydrothermal Organic Geochemistry’ at the Department for Earth Sciences and K.G. Jebsen Centre for Deep-Sea Research.
I’m from Mumbai (India) and I’ve completed my Bachelor’s degree in Geology (2014-2017) from St Xavier’s College, Mumbai and I also have a Master’s degree in Marine Geosciences (2017-2020) from University of Bremen (Germany). Where I worked with the working groups of Wolfgang Bach and Andrea Koschinsky (MARUM, University of Bremen). My master thesis ‘Geochemical investigations of hydrothermal fluids from the South-Sandwich plate, (Southern Ocean)’ was focussed on fluid geochemistry and thermodynamic modelling in unravelling the formation of magmatic and seawater derived deep-sea hydrothermal fluids.
My aim area of focus has been deep-sea hydrothermal systems, previously I’ve focussed on the inorganics and volatiles in these systems (essentially in the fluids) to understand the formation of these energy-rich fluids, using the chemistry of various species in the fluids (major, minor and trace elements), speciation and solubility calculations, fluid-rock interactions and catabolic thermodynamic models to further understand them in detail.

At UiB has a part of project HyPOD (Hydrothermal Production of Organic molecules: carbon transformation and Decomposition in ocean crust fluids), I’ll be working with Eoghan P. Reeves in understanding the formation of organic molecules in these fluids as a result of pyrolysis of microbial biomass under hydrothermal conditions. High temperature-pressure experiments will be conducted using lab-cultivated biomass (bacteria and archaea) under realistic redox conditions. I’ll be analysing these fluids for hydrocarbons, alcohols, carboxylic acids, amino acids and biomarkers. I’ll also be collaborating with Prof. Ida Helene Steen, Dr Håkon Dahle at Bio, UiB and Dr Florence Schubotz (MARUM, University of Bremen). I’m very excited to continue studying these marvellous deep-sea hydrothermal systems as a part of my PhD and I’m looking forward towards my stay in Bergen! You will find Samuel in room 4140. Welcome to GEO 🙂

Hi! My name is Hannah Petrie, and I have just joined the department to pursue an Equinor-funded PhD in integrated geological characterization of marine ground conditions for offshore wind in the North Sea.
I have a background in Geology and Petroleum Geoscience and have previously studied at the University of Edinburgh (2009-2013) and Imperial College London (2013-2014). After graduating, I moved to Bergen to work as an Exploration Geologist at Statoil/Equinor for four years and also worked as an Operations Geologist for almost two years.
My main area of focus has previously been evaluating hydrocarbon prospects; analyzing large seismic and well datasets within the Northern North Sea region at a range of stratigraphic levels. Most recently I have focused on regional seismic interpretation of Plio-Pleistocene stratigraphy, and I am very excited to continue to study the fascinating glacial geology of the Quaternary of the North Sea as part of my PhD project.

The project is associated with Equinor and with the Bergen Offshore Wind Centre (BOW), which covers a range of innovative offshore wind research projects. I look forward to working with BOW and my supervisors Christian Haug Eide and Haflidi Haflidason on investigating the ways in which a detailed and integrated understanding of the shallow Quaternary subsurface can be used to add value, reduce costs and uncertainties and increase efficiency and cross-disciplinary collaboration in offshore wind installation projects.
Please come by my office in 2G13C anytime if you want to know more about the project, or just to say hi! Welcome to GEO Hannah 🙂

Hei UIBGeo!
My name is Tim Cullen, and I have just started a postdoctoral research fellow position here in UiB working on the Petromaks II DeepRift project. Having visited Bergen a couple of times over the past couple of years for work in PhD in the Syn-Rift Systems project, I am delighted to be coming back and spending more time in the department and the city!
I’m looking forward to seeing plenty of friendly and familiar faces, and getting back into the swing of things here in Bergen.

I am a geologist and have recently finished my PhD at The University of Leeds in the UK, where I was working with Richard Collier, Dave Hodgson and Rob Gawthorpe looking at deep-water and deltaic syn-rift depositional systems in the Corinth Rift. My PhD focussed on understanding how deep-water syn-rift systems respond to the influence of structural and climatic variability. I’m going to be carrying on thinking about this and some others things and seeing if we can apply our work from the Corinth Rift in the previous syn-rift systems project to the Norwegian Continental shelf.
You’ll be able to find me in office no. 2101 once I’m in the department so feel free to pop by! Welcome back Tim 🙂
