Exploring and tailoring materials, atom by atom

A materials scientist at heart, I apply state of the art in situ microscopy for acquisition of elemental and chemical information at the atomic scale. With these tools, I explore the physical and chemical organization in low dimensional structures of solid materials, employing a combined experimental and theoretical approach.

I am the leading electron microscopist at LiU, administering a >100 MSEK investment in research infrastructure serving >100 direct users. For the past decade, I have worked hard to promote LiU to one of the more advanced microscopy environments in Europe. As a consequence, I am nationally recognized as Special Researcher (VR) and Infrastructure Research Fellow (SSF). Further I have organized the procurement for one of the most advanced electron microscopes in northern Europe and outlined the specifications for Ångströmhuset, a dedicated future proof microscopy environment.

My international network is substantial through years abroad in multiple research environments.

A new world of 2D material is opening up

Materials that are incredibly thin exhibit unique properties that make them appealing for energy storage, catalysis and water purification. LiU-researchers have developed a method that enables the synthesis of hundreds of new 2D materials.

Major investment in new equipment for materials research

The Wallenberg Initiative Materials Science for Sustainability, WISE, donates SEK 44 million to Linköping University for new scientific equipment that will contribute to cutting-edge materials research.

Sharpened chemical scissor paves the way for tailored nanomaterials

Using a “chemical scissor”, thin materials can be tailored even at atom level. This is shown in a study published in Science. The results pave the way for new materials for use in future sustainable energy production, energy storage and electronics.
