About Me

Welcome! I am an assistant professor at the Institute for Astronomy (IfA) of the University of Hawai'i. My research focuses on the structure and evolution of solar-type and low-mass stars using observational techniques such as asteroseismology, optical long-baseline interferometry, spectroscopy and broadband photometry, as well as the study of exoplanets through the characterization of their host stars.

I was born and raised in Vienna, Austria, and earned my PhD in Astrophysics at the University of Sydney, Australia, under supervision of Tim Bedding. I then worked as a member of the Kepler team at NASA Ames Research Center and the SETI Institute in Mountain View, California, before returning to the University of Sydney to take up an ARC DECRA fellowship. In January 2017 I joined the IfA faculty at the University of Hawai'i at Manoa.

Research

My group is involved in a number of research projects related to the study of stars and their planets in our galaxy. The links below provide brief summary of current research projects and recent publications. For more information see the NASA ADS listings of all my refereed publications, and my refereed first-author publications.

  • Asteroseismology of Cool Stars

  • Exoplanet Host Stars

  • Optical Long-Baseline Interferometry

  • Stellar Populations of Transit Surveys

  • Galactic Archeology

  • Adaptive Optics Imaging of Oscillating Stars
