Physikerin der Woche

Seit Januar 2018 stellen wir Ihnen wöchentlich eine Physikerin in einem kurzen Bericht vor. Möchten Sie selbst Ihr Forschungsgebiet vorstellen oder wollen Sie eine Physikerin in Deutschland oder eine deutsche Physikerin im Ausland (Bachelorstudentin, Masterstudentin, Doktorandin, Postdoktorandin, Gruppenleiterin, Professorin - Physikerinnen aller Karrierestufen können sich beteiligen) für unser Physikerin der Woche Projekt vorschlagen, dann kontaktieren Sie bitte Frau Dr. Ulrike Boehm (boehm at akc.dpg-physik.de). Einen Artikel über unsere Aktion in der Aprilausgabe des Physik-Journals finden Sie hier  


Dr. Daniela Huppenkothen (Seattle, WA) - Kalenderwoche 50

Daniela Huppenkothen is the Associate Director at the Institute for Data-Intensive Research in Astrophysics and Cosmology (DIRAC) at the University of Washington, and a Data Science Fellow at the University of Washington’s eScience Institute. She works on astrostatistics for astronomical time series, and is interested in how we can get as much information about astrophysical phenomena out of our data as possible, for everything from asteroids to black holes. She is excited about teaching data science to astronomers and researchers from other scientific disciplines, and about finding new ways to get researchers across different scientific domains to talk to one another.

Catmarna Sophia Küstner-Wetekam (Kassel) - Kalenderwoche 49

Catmarna is about to start her PhD at the University of Kassel in the framework of the SFB ELCH, where she is working in the field of luminescence and electron spectroscopy, investigating electronic processes in atoms, molecules and clusters. These are excited either by electron impact or photons radiation from synchrotron radiation facilities and FELs. In her master thesis, she developed an experiment for recording photon emission spectra of clusters in the XUV after electron impact excitation. With that it was possible to detect the emitted photons of the so called radiative charge transfer (RCT) in neon after electron impact excitation for the first time. Among other interparticle processes it is discussed as a prominent relaxation pathway in weakly-bound systems with a possible impact on radiation damage in biological systems.

Svenja Greif (Darmstadt) - Kalenderwoche 48

The equation of state of nuclear matter is not yet fully understood, especially in the region of high densities as they occur in neutron stars. As part of Svenja's doctoral thesis at the TU Darmstadt, she is investigating models of the equation of state and the associated predictions for the properties of neutron stars. Taking astrophysical observations into account, conclusions can be drawn about the radii of neutron stars and the equation of state.

She develops magnetic swimmers, which can be magnetically guided through the body in order to deliver therapeutics more precisely and reach regions of the body, which are difficult to access. She implements the tracking and actuation procedure with Magnetic Particle Imaging.

What are the fundamental building blocks of our universe? In Astrid Eichhorn's research, she explores the microscopic structure of matter and spacetime to understand the fundamental constituents of our universe at the tiny scale of 10^-35 m and below. As this length scale is too tiny to probe it with experiments, her research is theoretical. She spends most of her time with her team of PhD students and postdocs, working out equations that they hope encode the microscopic structure of the building blocks of our universe and discussing ideas how to connect the physics at microscopic scales to observable effects at larger scales.
