I am a fourth (and last) year PhD student advised by Harald Gall and Philipp Leitner. In the summer of 2015, I was a research intern with the Cloud DevOps group at the IBM T.J. Watson Research Center in New York. In the spring of 2016, I had the pleasure to work with Julia Rubin and Phillip Stanley-Marbell in Martin Rinard’s group at the Massachusetts Institute of Technology (MIT).
I received my master's and bachelor's degree in Computer Science from the Technical University of Vienna. I wrote my master thesis at the Distributed Systems Group in collaboration with Catchpoint Systems, where I completed a research internship in New York City.
My current research focus is on the intersection of Software Engineering and Cloud Computing. Specifically, my research explores how runtime feedback can assist developers to make better, data-driven decisions in the software development process.

I'm currently the head course assistant for Software Engineering Lab.
During my graduate studies in Vienna I have worked as a teaching assistant for the classes Advanced Software Engineering, Functional Programming, and Data Modeling.
From 2007 to 2010 I was a web developer, working mostly with PHP and Ruby in Vienna (itellico). I have also completed internships in the areas of Software Engineering in New York City (Catchpoint Systems), Web Development in Boston (Sound&Vision Media), and Technology Consulting in Germany (Accenture).
