Structural Food Physics and Soft Matter Self-Assembly
Welcome to my website. I am a soft matter researcher fascinated by self-assembly and the role of geometry in material science. After a number of years at the X-ray and Neutron Science group at the Niels Bohr Institute, University of Copenhagen I moved to a permanent position at the Dept. of Food Science to establish a group in Structural Food Physics and Soft Matter Self-Assembly. However, as of April 2021 I have taken up af joint position between these two institutes to tighten relations and to head the two SAXS instruments installed at NBI and FOOD. Please explore my research, teaching and other interests from the menus above.STUDENT PROJECTS - SEE HERE
Latest news
June 2024: Small-angle Scattering phd-school in August
We are organising a new PhD-School on Small-angle scattering: Principles, data analysis and advanced modeling to be held at University of Copenhagen August 19th to 23rd. We will welcome a suite of excellent lecturers - please see website for latest details.
July 2023: Shape2SAS is out
Our paper on Shape2SAS is out - a web-application for simulation of solution scattering from geometric shapes - going from simple to quite complex shapes. Requires no installation so we have found it very useful for teaching purposes to explore basic concepts and generate fast virtual data to import into Sasview for example to learn how to fit models. Read the paper HERE.
April 2023: Back from down under
Just returned from a 2-month research stay at Dept. of Chemistry at University of Sydney where I was visiting my long-term collaborator Prof. Stephen Hyde. The visit also allowed me to interact with a range of other scientist in Sydney, including at the Australian neutron facility ANSTO. Furher, I visited another collaborator at ANU in Canberra, Prof. Vanessa Robins and finally visited Prof. Gerd Schröder-Turk at Murdoch University in Perth where I gave a lecture for the Australian Institute of Physics about scattering methods in food science. Big thanks to the Carlsberg foundation and Niels Bohr Fondet for supporting the visit.
January 2023: Soft Matter paper accepted
Very proud of this work which had been a few years on the way. A gigantic effort by Martin Cramer Pedersen to make this work: we are presenting a new way of visualising and analysing patterns on negatively curved surfaces by mapping to the flat page using the Poincaré disc model of the hyperbolic plane. In analogy to a flat map of the earth, this allows to simplify very complex 3D patterns to 2D. Find the actual paper HERE.
May 2022: PhD School at NBI
Together with Martin Cramer Pedersen I am the local organizer of our 4th International PhD School on 'Geometry and Topology in Contemporary Material Science' which will be held from August 6-12 2022 at the Niels Bohr Institute. My fellow co-organizers and co-lecturers are Stephen Hyde (Uni. Sydney), Gerd Schröder-Turk (Murdoch, Perth), Myfanwy Evans (Uni. Potsdam), Philipp Schoenhoefer (Uni. Michigan) and Martin C. Pedersen (NBI). Read more HERE.
October 2021: Cover paper in PRL
Our latest paper on polymers under fast flow has made the cover of Phys. Rev. Letters. The paper describes a small-angle neutron scattering study of the structural relaxation of elongationally oriented, moderately stretched three-arm star polymers. Find the actual paper HERE.
September 2021: Work group leader
Together with Prof. Ben Boyd I am the new leader of the Northern Lights on Food working group on 'Food Colloids and Structured Interfaces' which is a theme under LINXS - Lund Institute of Advanced Neutron and X-ray Science. Read more about the network HERE.
April 2021: Editorial board membership
I have joined the open access journal Foods as an editorial board member. My first task will be as guest editor for a special issue on Food Physics. Browse the journal HERE.
January 2021: Agreement with Xenocs on new SAXS instrument
It is a great pleasure to announce that an agreement has been reached with Xenocs to deliver a new Nano-inXider instrument to be installed in my group at Dept. of Food Science to complement our existing x-ray scattering infrastructure at University of Copenhagen. Read more about the instrument HERE.
August 2020: Topological proximity paper out
The first paper from a collaboration with Martin Cramer Pedersen at the Niels Bohr Institute and Vanessa Robins at Applied Math, ANU is out. Using methods from the field of topological data analysis, we investigate the self-assembly and emergence of three-dimensional quasi-crystalline structures in a single-component colloidal system. From a topological perspective, there is a subtle, but direct connection between quasi-crystalline, crystalline and disordered states. Find the paper HERE.
July 2020: Nature Materials paper accepted!
Around 4 years ago I did some measurements which are now finally published as part of a larger body of work in Nature Materials. The research was led by my now long-term collaborator Prof. Matthias Arenz and the majority of the work was done by Gustav Sievers. In the paper we report on self-supported platinum-cobalt-oxide networks that break all performance records for electrochemical fuel-cell applications. Find the paper HERE.
January 2020: FOODHAY grant for new equipment
Through the new national research infrastructure initiative FOODHAY, I have received funding to buy a new combined SAXS/WAXS setup to be installed at FOOD later this year. More information (in danish) HERE.
November 2019: New member of the Nano-Science Center
I have joined the University of Copenhagen Nano-Science Center - a cross-faculty initiative between the Faculty of Science and the Faculty of Health and Medical Sciences. More information HERE.
October 2019: New paper in Soft Matter
Very proud of this new paper done in collaboration with Gerd Schröder-Turk and primarily our joint phd-student Tobias Hain - we show that star copolymers on a sphere self-assemble into patchy particles with structure and coordination corresponding to those found in the famous Thomson problem. Find the actual paper HERE.
September 2019: Paper on photosynthetic membranes
Very pleased that my PhD-student D. Jakubauskas got the first of his papers on photosynthetic membrane structure accepted into Scientific Reports. The paper contains scattering data from living cyanobacteria and details how to model this scattering. Find the actual paper HERE.
June 2019: Cover paper
A long experimental effort about self-assembly of milk proteins into well-defined nanotubes is finally out as a cover paper in Soft Matter. The study provides novel fundamental knowledge of the formation and structure of α-lactalbumin nanotubes under different conditions, which will facilitate future application of these nanotubes in food and pharmaceutical areas. Find the actual paper HERE.
November 2018: Cover paper
Our latest paper on miktoarm star self-assembly has made the cover of Polymer Physics. An integrated study using simulation and experiments allow us to understand the intricate self‐assembly across a wide range of the phase diagram in these interesting materials. Find the actual paper HERE.

February 2017: Teaching award!
I am very proud to be this years recipient of the 'Jens Martin Award' - the annual Niels Bohr Institute teaching award.
