I am an Assistant Professor at the Department of Materials Science and Engineering at KTH. My research group aspires to develop next-generation additive manufacturing processes that bridge the micro- and meso-scales, employs laser-based high-strain-rate micromechanics to study materials behavior at extreme strain rates, and in general focuses on structure-property relationships of various alloy systems.

I was a postdoc fellow at the Massachusetts Institute of Technology (2021-2023) and a postdoctoral researcher at ETH Zürich (2020). I graduated from ETH Zürich (PhD 2019, MSc 2012 (ETH Medal), BSc 2010).

Laser-induced particle impact testing with particle multitudes!

Our latest work outlines new opportunities for laser-induced particle impact testing (LIPIT): the study of many-particle phenomena with a quantitative view of the behavior of single particles.

Since a decade, LIPIT is driving advances in our quantitative understanding of high-velocity particle impacts and high-strain-rate micromechanics. However, single particle experiments do not speak to the inherently multi-particle phenomena known for example to influence cold-spray coating structure and properties.

Our work, published in Acta Materialia, demonstrates the deposition of particle-stacks with exact knowledge of their particle-velocity and -size spectra, and makes first statistical connections between particle kinetics and coating structure (strain and recrystallization, or particle velocities and coating defects).

I think we can look forward to a new era of multi-particle sequence experiments that explore the complexities of particle-based processes with powerful single-particle resolution!
