I am a Professor at the Dept. of Applied Physics, KTH-Royal Institute of Technology, but currently a STINT Fellow at the Department of Physics and Astronomy, Amherst College (fall 2017). My research group is working with ultrasound applied to lab-on-a-chip devices, a research field termed "Acoustofluidics". We are interested in using ultrasound for manipulation of particles and biological cells (acoustophoresis / acoustic trapping), and fluids (acoustic streaming). The most important application is 3D cell culture and micro-tissue and micro-tumor engineering.
