Marvin Wilhelm Detert

Originally, I am from Germany and did a bachelor’s and master’s degree in physics at the Leibniz University Hannover with a semester abroad in the United States. During my studies I focused on experimental work in solid state physics and the behavior at interfaces. After receiving my master’s degree, I decided to apply this knowledge in a different field and started to pursue a PhD in fluid dynamics at the University of Twente in the Netherlands in 2019. My work revolves around high-speed imaging of the nucleation and growth of microbubbles in multicomponent liquids that are created via rapid, local heating. The heating is caused by surface plasmon resonance in gold nanoparticles connecting my prior experiences in solid state physics with my current project in fluid dynamics.
At OIST I hope to experience a new and different environment and to broaden my knowledge about experimental techniques in fluid dynamics. I am looking forward to exciting experiments combining microfluidics, rheology, and birefringence.
In my leisure time, I enjoy sports like volleyball, badminton, and ballroom dancing, but you can also find me exploring new place and hiking in nature. Besides that, I try cooking new dishes with friends often and am always down for a karaoke session.

Johanna Roether
I completed Bachelor and Master in food process engineering at the Technical University of Munich. Afterwards, I started to work in packaging industry as a material developer for composite materials. Searching for something more exciting, I came across the very diverse research group of Prof. Willenbacher at the Karlsruhe Institute of Technology. The PhD project I started there in 2015 is related to microrheology of biopolymers. This method allows us to locally characterize mechanical properties of polymeric biomaterials. Recently, we even started to use it to study matrix remodeling by living (and differentiating) human cells.
Before finishing my PhD, I now took the opportunity to learn something completely different and so I hope to get to know LSPR sensing and how to use it to study DNA elongation. Besides, I love hiking, climbing, snowboarding, in general being outdoors, playing handball (and teaching it to school children), and basically anything related to being active and/or outside.
