Michela La Bella (PhD at ID11)

I am a PhD student working on a project entitled “In situ studies of cement hydration and alteration processes using nanoscale X-ray diffraction techniques”. I am a geologist with a vocation on mineralogy and I enjoy using all the techniques available at ID11 for a better comprehension of my complicated hydraulic binders. I exploit 3DXRD and phase contrast tomography to follow in-situ processes at different time and spatial scales.


Vincent Beyrand (Visiting Scientist at BM18)

Fascinated by natural sciences in general with a particular interest in paleontology, i like going into the smallest details to understand the evolution of living forms surrounding us. Appreciate to highlight what is usually not visible. Former PhD student at Palacky University (Czech Republic) and currently postodoctoral students at Zurich University (Switzerland) as well as visiting scientist at the ESRF. Moved from dinosaur endocranial anatomy to human evolution.

Dr. Researcher Benoit Cordonnier - CompSci: Training in Computational  Science


Benoit Cordonnier (Visiting Scientist at ID19)

Volcanologist, I relentlessly explored Earth gears and clockwork. I specialized myself in experimental geology, mimicking natural processes and observing what is normally hidden by millions of years or kilometers of depth.  Academic and proud tech-nerd, I always look for new approaches to make progress our understanding in rock mechanics. It naturally pushed me to settle at the European synchrotron (ESRF), this unparalleled laboratory.

Luis Carlos Colocho Hurtarte (Post-Doc at ID21)

I am a biogeochemist with a backbone in agriculture, thus my primary research objective is the better understanding of the global element cycles at the earths critical zone, where food-production takes place. My primary interest is the understanding of underlying microscopic mechanisms that control phenomena like nutrient cycling and carbon storage in soils. My experience in biogeochemistry allows me to explore fundamental mechanisms occurring at the root-microbiome-soil interface using state-of-the-art in-situ synchrotron based microspectroscopy.


Kathleen Dollman (Post-Doc at BM18)

I always have been fascinated by all things ancient, and I became hooked on ancient, fossilized animals when I visited the Evolutionary Studies Institute, Johannesburg. My research focus is on the ancestors of crocodiles, the very earliest members of this once large and very diverse group of animals.The synchrotron light source allows us to see inside fossils with unprecedented detail, and I am excited to investigate the ecology and biology of many different groups of animals with this amazing technological resource.

I did my undergraduate studies at the University of the Free State (South Africa), and my postgraduate studies at the Evolutionary Studies Institute, University of Witwatersrand (South Africa).

Carlotta Giacobbe (Beamline scientist at ID11)

I am a crystallographer involved in environmental mineralogy. For more than 10 years now, I have been studying natural fibres as well as asbestos, to understand the relationship between their atomic structure and their pathogenicity. Enabling new methods for their characterization is my everyday job combining single crystal, powder diffraction and tomographic techniques. Lately I am also focussing on construction materials for a greener and more efficient production.

Bratislav Lukic (Post-Doc at ID19)

With my civil engineering background built around geomechanics, I constantly search for solutions of building a more resilient and sustainable future. During this quest, I explore how geomaterials behave under extreme scenarios induced by impacts and shocks on microscopic scales both in space and time. The ID19 beamline is the only one in the world where such phenomena can be studied at these scales at the same time which naturally motivated me to join the team.


Angelika Dorothea Rosa (Scientist at ID24-DCM/BM23)

I am an experimental mineralogist and geochemist, my primary objective is a better comprehension of global element cycles and geodynamical processes taking place in the deep Earth’s interior. I am particularly interested in understanding the underlying microscopic mechanisms that are at the origin of global scale phenomena. I have a long-standing experience in experimental mineralogy that enabled me extracting fundamental physico-chemical properties of geomaterials at the relevant extreme P/T conditions of the Earth’s interior (>130 GPa, > 4000 K) using state-of-the-art in-situ methods and synchrotron X-ray radiation.


Harald Müller (Chemistry Lab Manager)

Chemistry & Micro-Imaging Chemist, with a strong preparative background and a long experience in the field. The Local Mineralogy Project: Initially a purely private initiative, collecting minerals in the Isère department has gradually evolved over the last ten years from a pastime activity into a more systematic search and identification of (local) and (occasionally hitherto unknown) mineral specimen. The expertise and active involvement of ESRF staff scientists (W. Crichton, M. Hanfland) and visitors (M. Merlini) as well as the characterization resources offered by the ESRF have been invaluable. Since the early beginnings in 2005, this activity has been extended and includes also field trips and collecting opportunities outside of the initial area.

Jean-Alexis Hernandez (Junior Scientist at ID24-HPLF)

At the intersection between mineralogy, shock and plasma physics, I am studying minerals and liquid phases presenting an interest for the understanding of the deep early Earth, super-Earths and water-rich exoplanets. In order to reproduce the extreme conditions typical of these planetary interiors (up to several hundred GPa and thousands of Kelvin), I combine high-pressure experiments and atomistic simulations. In particular, I use and develop laser-driven dynamic compressions (on- and off-Hugoniot) coupled or not with ultrafast X-ray diffraction, and soon X-ray absorption spectroscopy on ID24-ED with the High Power Laser Facility.

E. Bazarkina (CRG BM20/BM16/BM30)

I am studying the solubility of minerals and the state of dissolved metals in aqueous solutions under conditions appearing in the crust and upper mantle (up to 500°C and 2000 bar). The ultimate goal is to identify the geochemical conditions required to form hydrothermal ore deposits (i.e. when the highest metal concentrations in fluids can be riched), compare metal behaviors, and constrain the geochemical tracers of natural processes.
