I'm fascinated by work in hospitals. Physics knowledge can be used directly to do good, because it contributes to the treatment of each individual patient. I find it very satisfying to be directly involved in the therapy of so many patients. In many other fields of physics, you are far removed from the actual application.
In the end, however, I decided to work in industry because there are more possibilities. In my current position, I can visit many more hospitals and learn how radiation therapy is applied worldwide. I am curious about this and I am interested in what different approaches are available. This knowledge can be used in turn for optimizing PTW products. As a result, my work can benefit a lot of hospitals in this way. Although I have much less patient contact, which is a pity, on the other hand it is also positive, because you sometimes have to deal with very sad fates in a hospital that can cause you a lot of stress. This is a long way from being the case in industry.
