“Even though I’m a professor now, I still spend a lot of time in the lab, as I know that when I’m at the microscope, working hands on, that’s when I get the new ideas,” says Peter Nilsson, professor of organic chemistry at Linköping University (LiU) in Sweden. He develops tracer molecules that can recognize different proteins. The molecules are used in research, including Alzheimer’s disease studies. Interdisciplinary collaboration is one of the keys to his success.
