Why did you choose Engineering Physics at Chalmers?
"I had read that it was the least practical education of all and thought “What a great thing! Then nothing can go wrong.” I had joined the Electrical Program at the upper secondary school which was a very practical education where things always broke down. I had it easy for math when I was younger and physics was really an extension of math for me. But the program turned out to be much more demanding than I thought. My trick was to always write my own summaries after reading the texts in the books, so that I actually understood what it was that we learned."
How would you describe your student life?
"It was almost more hectic than the studies because I wanted to be part of everything, but for me it was also a prerequisite for being able to do the studies. I was in the F-Spexet where I learned to be a good speaker. I have great use for that now when I give presentations. I was also in a public relations association at Chalmers and it was a lot of fun, but also a lot of effort. There I learned how to organize my time in a good way."
What are you working on at Nasa?
"We want to find water and life on other planets. Often, water is an indication of life, but also a sign that we may be able to visit other planets and settle there in the future. One method used to look for these things is to send out spacecrafts that look at other planets, moons and asteroids with radar. When you do this today, the entire vehicle has to move in order to map a surface. It runs slowly and requires a lot of energy. My work is to try to streamline the process of phase shifters controlled by micromotors, which in turn can be used to design electrically controllable antennas that do not need to move when mapping a surface."
What was the best thing you got from your education?
"Learning to learn, the ability to get into a subject or process quickly and having methods to do it. I am also happy for all the friends I made for life. We are a great gang of girls from Engineering Physics who all chose to work with very different things and we meet as often as we can!"
