Tjark Sievers

I'm a Physics master student currently working on my master thesis, a joint project between Prof. Tim Wehling at Universität Hamburg and Prof. Annica Black-Schaffer at Uppsala University. My research interest is the theory of superconductivity in strongly correlated electron systems.

During my time working at the PHYSnet data centre, I developed a web application based on Flask to interface with a database containing data about devices we managed. Some Tasks using this database were giving out PCs, Laptops and monitors to research groups, handling taking these devices back and filling out everything needed by the university management when the devices are coming in. I managed to simplify many steps, for example automatically filling out the fields for hostnames with a specified naming scheme based on what hostnames are already given out or providing a simple interface to match inventory numbers given by the university management to the serial numbers of devices that were freshly delivered and then writing it into the database.

In summary, my bachelor project was about a software package used in the research group and how to best run it on our local compute cluster. When I started my bachelor project, the group of Professor Wehling was starting pretty fresh at the university. The project we ended up on was to look at Quantum Espresso, evaluating how it runs best on our local compute cluster Quantum Espresso is a software package implementing Density Functional Theory (DFT), which is a very successful method to calculate electronic properties of materials.
