Professional info

 

I am a post-doctoral researcher at Aalto University starting from September 2022. I have been using X-ray methods to characterize the nanoscale structure of cellulose and other natural materials. I strive to critically evaluate the X-ray scattering methods I am using and to compliment them with X-ray microtomography and computational and analytical models. I am also looking for work opportunities both in Finland and abroad in the field of experimental physics. I hope to be able to combine experimental work, scientific research and programming in my future profession.
