"We have developed atom-sized quantum sensors in diamonds with unprecedented sensing capabilities. This will unlock next-generation applications for industrial clients this year."

What is your role in QuantumDiamonds?

During my PhD in Dominik's laboratories, I spent the bulk of my time designing, building and using experiments using diamond-based quantum sensors. The hardware and software skills I acquired during this time make me an ideal candidate for the technical lead at QuantumDiamonds. Here I will be responsible for industrial partnerships and in-house development.

You worked with NV centers in diamond that can have various applications. What exactly were you researching?

The big advantage of NV-centers is their incredible spatial resolution. In our laboratory we used a technique for the detection of chemicals in a solution, called nuclear magnetic resonance. With NV-centers much smaller volumes can be proved, than with conventional devices. I in particular worked towards a highly resolved MRI device. This might enable MRI images of single cells, similar to the ones we all are used to from Hospitals.

Apart from healthcare applications, where do you see the biggest use case of NV-centers in a couple years?

I really think the semiconductor industry could benefit greatly from NV-centers. The imaging of currents on integrated devices looks very promising. There is a clear improvement compared to established technologies and the potential benefits in this multi-billion dollar industry are huge.

In general, I would also not underestimate the general scientific market. NV-centers have started to become a tool, not something that is researched itself. Commercial devices are already available and will improve rapidly. The insights this will generate in the many diverse fields in which NV-centers are used could be revolutionary.

What do you like about working at QuantumDiamonds?

The team! As technical lead it is quite obvious that I am passionate about the technology, but working with my co-founders is truly great. Already during my PhD I got to know and love working with Kristina, Dominik and Robin, and Kevin is a perfect fit. All of them are motivated and well-spirited people who make working with them a joy.
