Particle Astrophysics at the University of Zürich

Group members


Prof. Laura Baudis (homepage)

Laura Baudis arrived at the UZH in August 2007. She is dedicating her research to answer fundamental questions in particle astrophysics and cosmology. Before moving to Zurich, she spent one year as a professor at the RWTH Aachen University, two years as an assistant professor at the University of Florida, and three years at Stanford University.

She is mainly involved in direct searches for particle dark matter with liquid xenon and cryogenic (mK) Ge and Si detectors, and in the search for the neutrinoless double beta decay in 76-Ge. Prior to moving to California, she spent four years at the Max Planck Institute for Nuclear Physics in Heidelberg. In Heidelberg, she was involved in the Heidelberg-Moscow experiment, which had the goal to measure the neutrino mass by detecting a very rare nuclear decay in 76-Ge, and in the Heidelberg Dark Matter Search experiment.

Her other passions are her two children, Nathan and Naima.



Dr. Alexander Kish (homepage)

Alex is a Research Associate (Oberassistent) in our group. He joined XENON collaboration in January 2007, when he moved to Aachen following his interest in noble gas particle detectors and in dark matter searches, and did his PhD with the XENON100 experiment and succefully defended at the University of Zurich in 2011. Prior to this he had worked at International Sakharov Environmental University and National Academy of Science in Minsk (Belarus), in the fields of nuclear physics, spin chemistry and radioecology.

He is leading working groups of the XENON1T project, currentl responsible for photosensors and detector calibrations (with radioactive and light sources), and is a member of the GERDA collaboration and the DARWIN Consortium. His main reasearch interests are rare-events searches, such as direct and indirect dark matter detection, neutrino physics, photodetection, noble gas technology, Monte Carlo simulations, low-background techniques, and high-purity germanium detectors.

Postdocs

Dr. Michelle Galloway

Michelle received her Ph.D. from the University of California at Berkeley with a focus on gamma-ray spectroscopy and imaging for nuclear astrophysics and environmental monitoring applications. Her interest in observing and understanding the invisible matter in the universe prompted her to join the XENON group in 2014. Her favourite activities are hiking, swimming, and playing music.

Dr. Roman Hiller

Roman works in our group since June 2016, shortly after obtaining his Ph.D. at the Karlsruhe Institute of Technology, where he worked on Tunka-Rex, an experiment for radio detection of cosmic rays. He is broadly interested in astroparticle physics and currently focuses on rare event searches with Germanium detectors in the framework of the GERDA experiment. Outside of physics, he enjoys playing with his daugther, and, if time permits, does a variety of different sports, like football, climbing and skiing.

Dr. Shingo Kazama

Shingo Kazama has joined our XENON group in April 2016 as a JSPS postdoctoral fellow. He studied physics at the University of Tokyo and did his Ph.D thesis in the ATLAS experiment. His main research interests are the direct detection of dark matter and the discovery of supersymmetric particles.

His favorite activities besides physics are chorus and traveling.

Dr. Shayne E. Reichard

Shayne arrived in Zurich in May 2017, after earning his Ph.D. in XENON's Purdue group in December 2016 and spending the first three months of 2017 as XENON's run coordinator at Gran Sasso. His graduate thesis involved the development of novel calibration techniques for liquid xenon detectors as well as the detection of non-standard dark matter and supernova neutrinos. As a post-doctoral researcher, he will continue to search for this elusive dark matter and investigate what solar and galactic sources can teach us about neutrino physics in both XENON and DARWIN. Outside of the lab, Shayne likes to run, hike, travel, and practice martial arts.

Dr. Patricia Sanchez

Patricia has joined to our group in December 2017. She is one of the new postdocs of the Darwin Collaboration. She studied physics at the University of Granada where she also obtained her PhD. Her thesis was focused on the detection of ultra-high-energy cosmic rays with data of the Pierre Auger Observatory. Besides astroparticles, her main research interests are the experiments with very low background conditions, especially the ones dedicated to the searches of dark matter and neutrinos. In addition she is particularly interested on hardware development for TPCs. Outside work what she likes most is sharing time with her friends, but she also enjoys traveling around and attending to zumba lessons.
