<p>I am a PhD student at <a href="http://www.mpi-sws.org/" target="_blank">Max Planck Institute for Software Systems (MPI-SWS)</a> and <a href="http://www.uni-saarland.de/" target="_blank">Saarland University</a> under the supervision of <a href="http://www.mpi-sws.org/~dreyer/" target="_blank">Derek Dreyer</a>, head of the <a href="http://plv.mpi-sws.org/" target="_blank">Foundations of Programming group</a>.</p>

<p>Previously, I did my Bachelor's thesis in computer science at the <a href="http://www.cdl.uni-saarland.de/index.php">Compiler Design chair</a> of the university (also see below).</p>

<p>I am currently working on logics to support modular reasoning about higher-order concurrent imperative programs. The focus is on providing simple building blocks that are powerful enough to recover previous reasoning techniques.</p>

<p>In my free time, I like to run internet services myself and work on free software.
This goes hand-in-hand with my pursuit of defending our privacy rights and our freedom in the digital world.
