Professional info

 

I am data scientist/programmer/physicist. I have been using X-ray methods to characterize the nanoscale structure of cellulose and other natural materials and using various data analysis and programming methods to work on multidimensional and challenging data. I am also looking for work opportunities in Finland in the field of experimental physics, medical physics, data/image analysis and programming. I hope to be able to combine some combination of experimental work, scientific research and programming in the next steps of my career.
