During the bioinformatic study at the Department of Mathematics and Computer Science at Freie Universität Berlin, Stefan Mendt joined the group Physiology in Space and Extreme Environments as student assistant and completed a research internship on modeling circadian rhythms in humans. In 2012 Mr. Mendt wrote his Master’s thesis at Center for Space Medicine Berlin (ZWMB) about the effect of long-term bed-rest on the circadian temperature rhythm.

Since 2012 as doctoral student of Prof. Gunga, Mr. Mendt has been working on his thesis “Circadian core body temperature rhythm before during and after long-term space flights”. As research associate at the Charité Berlin since 2015, he also holds various courses in human physiology for bioinformatics and medicine students.

 

Research focus

  • Effects of gravity and extreme environments on circadian rhythms

 

Additionaly, Mr. Mendt supports the group in processing and analysing different types of data (ECG, EEG, HRV, cognition etc.) generated by the group’s numerous research projects. His favourite tool is the programming language R, a software environment for statistical computing and graphics.

 

Mr. Mendt is currently working on physiological data of

  • astronauts from ISS-project CIRCADIAN RHYTHM
  • subjects from the isolation experiment MARS500
  • patients after mild therapeutic hypothermia

 

Awards

  • 2014 Second Poster Prize for Monitoring Circadian Rhythm of Core Body Temperature Using the Heat-Flux Approach is Superior to Skin Surface Temperature Recordings at the 52nd Annual Scientific Meeting of Deutsche Gesellschaft für Luft- und Raumfahrtmedizin (DGLRM) e.V.
  • 2011 Nathan Zuntz Scholarship (1 year)
