I am a PhD-student of Biomedical Enginnering, specializing in biomedical optics. My research involves developing new, faster algorithms for imaging microcirculation, and is focused on hardware-platforms such as FPGA and GPU.

Biomedical optics & microcirculation

Microcirculation is a term that refers to blood flow within the smallest blood vessels in the body. By studying the blood flow in the smallest blood vessels you can retrieve information about the healing process for burn injuries or other conditions, such as ”Raynaud’s phenomenon”. I work with developing faster and better algorithms for visualization of microcirculation, with a special focus on hardware-platforms such as FPGA and GPU. 

Academic achievements:

Master of Science in Applied Physics and Electrical Engineering, with specialization "system on chip", from Linköping University
