Markus studied biology and chemistry at the Ludwig-Maximilians-University Munich, Germany. He then joined the group of Gerhard Neuweiler at the same university, working on a Ph.D. project focusing on the efferent control of the bat cochlea. After completing his Ph.D., Markus then went on to carry out post-doctoral studies at the lab of Ian Russell, University of Sussex, England, working on the cochlear mechanics of Prestin mice mutants. After a short stint in the industry, he then joined the University Hospital Munich, Germany, for a translational research project revolving around cochlear homeostasis and related conditions, such as Meniere’s disease. During the 10 years he spent in this position, he also developed a strong interest in the impact of low-frequency sound on the mammalian inner ear. In 2021, he was appointed associate professor at NTNU’s audiology group at Trondheim, Norway.
