Zsuzsa Márka (she/her) is a scientist at the Columbia Astrophysics Laboratory. She works on the LIGO (Laser Interferometer Gravitational-wave Observatory) project, the experiment that in 2016 announced the first direct detection of gravitational-waves.
At Columbia University, Márka led the project that built the LIGO and KAGRA timing distribution systems, key subsystems for instrument control and gravitational wave data acquisition.
Márka works with members of the Columbia Experimental Gravity group on various aspects of gravitational-wave multimessenger astrophysics with a special focus on joint high-energy neutrino and gravitational wave searches. She is also involved in the development of new technologies through the Columbia BioOptics Group with a focus on combating disease transmitting vectors via optical and acoustic technologies and a murine model of neurodegenerative diseases.
