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).  


Anna Lippert (Cambridge, UK) - Kalenderwoche 24

Anna is a PhD student in the Biophysics Group of Prof. Klenerman in Cambridge. Her research project is a collaboration with the Immunology group of Simon Davis in Oxford where she examines the effect of pharmatceutically relevant antibodies on the immune system. Antibodies are widely used for the treatment of diseases and while their efficacy is shown, little is known about the underlying mechanism. Anna uses Single-molecule Imaging to examine the influence of antibodies on single proteins and protein distributions on the cell membrane of immune system cells.

Shreenanda Ghosh (Dresden) - Kalenderwoche 19

Shreenanda Ghosh is a PhD student at the Institute of Solid State and Materials at the TU Dresden. She is working with one of the most compelling unconventional superconductors till date, Strontium Ruthenate (Sr2RuO4).

By combining Muon spin relaxation (which is an unique tool to study structural and dynamical processes that are taking place in the bulk of a material in an atomic scale) and the application of uniaxial pressure (which is a good way to perturb a material without introducing any disorder) she is searches for a conclusive evidence regarding the superconducting order parameter of Strontium Ruthenate. For this purpose her group has developed an uniaxial pressure device which is expected to widen the range of applications of Muon spin relaxation method.

The photo shows Shreenanda at her first conference talk at The 14th International Conference on Muon Spin Rotation, Relaxation and Resonance (µSR2017) held in Sapporo, Japan.

Dr. Kirsten Schnorr (Heidelberg) - Kalenderwoche 16

Kirsten is currently an Ewald fellow of the Volkswagen foundation working on research with Free-Electron Lasers. She explores the dynamics of molecules on the femtosecond time-scale with high-energetic laser pulses from the XUV to the X-ray regime. Using high-energetic photons for time-resolved experiments offers the advantage that specific atoms and states within a molecule can be probed which allows to follow charge- and energy-transfer in real time with atomic resolution.

Dr. Zara Bagdasarian (Jülich) - Kalenderwoche 15

Zara is a Postdoctoral researcher in the neutrino group at IKP-2, Forschungszentrum Jülich. She received her PhD within the Cotutelle agreement between University of Cologne (Germany) and Tbilisi State University (Georgia). Nowadays she is mostly busy hunting neutrinos coming from the Sun and arriving at Laboratori Nazionali del Gran Sasso (Italy). Even though billions of solar neutrinos pass every second through your thumb, an extremely low interaction probability makes researching neutrinos a very challenging quest. Zara is a member of the Borexino collaboration, that utilizes detector with the most radiopure scintillator in the world, located in the largest underground laboratory in the world.

Zahra Motahar (Oldenburg) - Kalenderwoche 11

Zahra is a PhD student at the University of Oldenburg. She is a member of the Models of Gravity Research Training Group. In this Research Training Group they discuss various string theory motivated gravity models given by various generalized Einstein equations. First they derive and discuss solutions of these generalized Einstein equations, then they explore the resulting space-times through the motion of test objects, and finally they also apply the results to astrophysically and cosmologically given situations. Zarah is working on alternative theories of gravity in neutron stars. Neutron stars are one of the most fascinating objects in the universe created by the collapsed core of a giant star. They are incredibly dense and compact objects representing an ideal laboratory to test alternative theories of gravity.

Dr. Karen Disseau (Göttingen) - Kalenderwoche 10

Karen did her PhD thesis in Paris Observatory (she is French), then she came to Germany (Göttingen) for a post-doc at the Institut für Astrophysik (IAG). She works on ELT instrumentation (European Extremely Large Telescope). In the frame of the MOSAIC Phase A project (Multi-object spectrograph for the ELT), she simulated (with an end-to-end simulator that she contributed to develop) the observation of high redshift galaxy spectra with the instrument. These simulations are used to define the high level specifications of the instrument and to evaluate the impact of design trade-offs on the instrument performances. As she is part of the engineer group at IAG, she recently also started to work on Finite Element Analysis of support structure for different spectrographs that will be mounted on the European telescopes in Chile.
