European XFEL’s new scientific director talks about her career, her new role and her love for swimming.
On 1 September Sakura Pascarelli joined the European XFEL from the ESRF. In her role as scientific director she is responsible for the development of the four hard X-ray instruments. She spoke to Rosemary Wilson about her career, her new role and her love for swimming.
How did you get into science?
I spent part of my childhood in Burma and Indonesia. The American school system there enabled you to do lessons at your level, meaning you stayed interested and engaged. I really liked maths which I did with kids a few years older than me. I remember also doing experiments. I liked seeing things explode and break and try to understand why. Later on in Italy, I studied physics – not because I was particularly talented, but because I enjoyed it.
You joined ESRF at a time when the facility was still being built. What parallels can you see between that time, and now here at European XFEL?
I went to the ESRF to build one of the first beamlines there. We didn’t know what we would be able to discover or measure with this new machine. Here at European XFEL I see some of that same excitement. That opportunity taught me so much about instrumentation, and coordinating the construction of a beamline. But it is a different world now. Back then a good scientist with a solid background in physics, X-ray optics or instrumentation, could build a group and build a beamline. That is not possible here. This is so much more complicated. Here you need experts in X-rays, lasers, electronics, detectors. We don’t really know how to measure a femtosecond pulse let alone synchronise it with another laser! To run these instruments we need group leaders who are really good managers. This is so important. It is no longer enough for someone to be just a good scientist. At European XFEL we need to make sure the groups are well structured, well managed and that the people are happy. That might be difficult in the beginning when things don’t work, but when people see that their work is recognized, satisfaction and productivity increases.
