Ruth Titz-Weider studied physics at the University of Bonn and received her doctorate in 1991 with a thesis on heterodyne receivers in the terahertz
range at the Max Planck Institute for Radio Astronomy.
After completing her doctorate, she joined the then DLR Institute of Optoelectronics in Oberpfaffenhofen, where she developed an atmospheric physics receiver for the Falcon research aircraft. In 1997, she went to the newly founded DLR Institute of Space Sensor Systems in Berlin-Adlershof, focusing on the SOFIA research aircraft and public relations. After taking parental leave, she transferred to the field of extrasolar planets at the DLR Institute of Planetary Research. In addition to her technical work in the field of exoplanets, she is the point of contact for public relations work on this topic and on relevant missions such as PLATO.
She is often invited to give lectures in planetariums and other extracurricular educational venues, organises teacher training courses and was a member of the Berlin state jury for 'Jugend forscht' for ten years.
