Modified and Quantum Gravity From Theory to Experimental Searches on All Scales

Christian Pfeifer
is currently a postdoctoral fellow at the Center of Applied Space Technology and Microgravity (ZARM) at the University of Bremen, Germany. He obtained his Ph.D. in mathematical theoretical physics from the University of Hamburg in 2013. After that, he worked as a postdoc at the University of Hannover (2014-2016), Germany, and at the University of Tartu, Estonia (2017-2020). His work focuses on the use of geometric concepts beyond Riemannian geometry in the description of gravity, quantum gravity phenomenology, and the propagation of fields in media. Moreover, his work addresses the comparison of predictions from classical and quantum gravity with observations on cosmological, astrophysical, and laboratory scales.

Claus Lämmerzahl
 is an honorary professor at the University of Bremen, Germany, a director of the space science division of the Center of Applied Space Technology and Microgravity (ZARM) since 2012, and a professor of theoretical physics at the University of Oldenburg, Germany, since 2010. He obtained his Ph.D. from the University of Konstanz in 1989, where he also habilitated in 1997. In between, he held several postdoc positions at various universities: Paris, France (1994-1996), Konstanz, Germany (1996-2000), Dusseldorf, Germany (2000-2003), and Bremen (2003-2008). His main research interests include general relativity, relativistic astrophysics, gravity beyond special and general relativity, as well as the interplay between quantum systems and gravity. A particular focus of his research lies on the opportunities to test properties of gravity with quantum systems.
