I am an associate professor within the Embedded and Networked Systems Group of Delft University of Technology, leading Sustainable Systems Lab. My research vision is to make Internet of Things free from batteries, less polluting and sustainable. With my students I do research that is experiment- and systems-oriented (where system is a creation of new hardware and software). I have obtained my MSc (magister inżynier) degree from Wrocław University of Science and Technology in October 2004, and my PhD degree from Delft University of Technology in April 2009.
