GROUP STATEMENT:
-
We work across disciplines which makes collaboration and communication essential.
-
We make time to play in the lab and test ideas.
-
We treat each other as peers and we welcome any interested students, postdocs, scholars or collaborators, regardless the branch of academic training.
-
I strive to have a group reflecting the diversity seen in society and I aim to help decrease the extra hurdles STEM women and minorities are facing compared to cis-male colleagues in this otherwise wonderful world of science.
-
We all have different ways of learning, we all bring different skills to the table and we all need different input to connect the dots. I am committed to create a learning space where everyone can participate.

Jaime Quesada Sanz
MSc.
DNA-MINERAL STABILITY IN NATURAL ENVIRONMENTS
Jaime will be using atomic force microscopy and bulk adsorptio experiments to investigate the nano level interactions between DNA and minerals in a range of environmental solutions. His results can be used to access DNA leaking in sediments and to improve extraction protecols for eDNA
Approach and tools:
AFM imaging, Video rate AFM and force spectroscopy., UV-Vis.
Magnus August R Harding
Project Student (MSc)
DEGRADATION KINETICS OF MINERAL ADSORBED DNA BY DNase
Magnus has a background in geology and palaeontology, and is interested in understanding the processes taking place during fossilization and the fate of organic molecules as they enter the geosphere. Here he will elucidate the preservation potential of environmental DNA.
Approach and tools:
AFM imaging in air, in liquid and using video rate
Chloé Martins
Erasmus Student
ROLE OF MINERALS IN THE ORIGIN OF LIFE
Chloé was suppose to join the group and do experimental work on propagation of antibiotic resistance genes in the environment. She planned to investigate conformation and behavior of DNA adsorbed to soil minerals. However, because of Covid-19 related lock-downs her project has been transformed to a literature study on the role of minerals in the origin of life.
Approach and tools:
AFM imaging in air, in liquid and using video rate
Xi Chen
Master student
BIOFILMS
Many microbes rely on anchoring themselves to mineral surfaces where they make biofilms enhancing their survival and facilitate gene transfers. Xi will be using her chemistry background to explore the differences in affinities between microbes and minerals and address if there is an interdependence with environmental conditions
Approach and tools:
Flow through optical microscopy, AFM imaging, SEM, EDX, force spectroscopy.
Léa Dieudonné
Erasmus student
DNA CONFORMATION
Léa has been looking into DNA conformation on different minerals and explore how we can manipulate the DNA-mineral interaction.
Approach and tools:
AFM imaging and force spectroscopy.
Anne Rath Nielsen
PhD student
ARTIFICIAL NACRE
Composite materials are nature’s strategy for creating strong and tough materials. Anne aim to understand the mineralization dynamics of CaCO3 formation on synthetic bio-polymers to develop nacre analog materials.
Anne is currently writing up her PhD thesis.
Approach and tools:
Flow through optical microscopy, AFM imaging, SEM, EDX, Constant composition method, in-situ UV-VIS, XRD.
Kasper Primdal Olesen
Project student
HETEROGENEOUS NUCLEATION OF CaCO3
Kasper studied heterogeneous nucleation and growth of calcite on mineral surfaces and polymers present in the environment. The aim was to elucidate surfaces that inhibit and enhance calcite formation.
Approach and tools:
SEM, EDX, Constant composition, diffusion experiments.
Lasse Nikolajsen
Bachelor Student
HETEROGENEOUS CALCITE FORMATION
Lasse studied the thermo dynamic barrier to nucleation on a range of substrates. We set up nice system to study nucleation in-situ with optical microscopy under constant flow and steady state conditions.
Approach and tools:
Flow through optical microscopy, SEM, EDX, in-situ UV-VIS, XRD.
Svend Harry Canas Weihe
Master student
Svend studied the rate of hematite reduction by the reducing bacteria Shewanella. He showed how the presence of organic compounds interfere with the mineral-microbe system paving the way for a better understanding of natural systems.
Approach and tools:
Glove boxes, ferrozine metod, TEM, SEM, EDX.
Mia Nielsen
PhD student
INORGANIC INHIBITION OF CARBONATES
