I am an international postdoctoral fellow at Umeå University and the Technical University of Denmark. My work concerns the detection of chemical and biological substances using spectroscopic methods.
Rasmus obtained his master's degree in Engineering Physics from Umeå University in 2020, with a focus on material science and nanoscience. During an exchange year at the City University of Hong Kong in 2018, he studied advanced optics and laser physics. He then combined these interests in his doctoral studies at Umeå University and the Swedish Defense Research Agency, where he worked on developing optical methods to study harmful chemical and biological substances. His doctoral studies culminated in 2025 in the thesis "Light on the Murderer: Detection of harmful chemical and biological substances using optical spectroscopy" which was also named the best thesis in physics from a Swedish University in 2025 by the Swedish Society of Physics. After receiving funding from the Swedish Research Council in 2025, he is now a postdoctoral fellow stationed at the Technical University of Denmark.
In his research, Rasmus uses spectroscopic methods such as Raman, absorbance and fluorescence spectroscopy, as well as optical tweezers to study and characterize everything from simple chemicals to complex microorganisms. Furthermore, he develops sensitive detection methods for harmful chemicals such as narcotics and nerve agents, as well as disease-causing bacteria and resistant bacterial spores.
In addition to his research, Rasmus has taught optics and wave physics, and worked as an assistant program manager for the MSc program in Technical Physics at Umeå University. In his spare time, Rasmus likes trivia, long-distance running, and tabletop role-playing games.
