Current and previous positions

• Since November 2019 I'm a postdoc in the group of Olaf Beyersdorff at Friedrich Schiller University in Jena, Germany, funded by an FWF Erwin Schrödinger Fellowship.
• Until October 2019 I was a PhD student funded by the FWF project P27721 and partially by Doctoral College Logical Methods in Computer Science, and I was also a project assistant in the Algorithms and Complexity Group. I started my PhD studies in September 2015 under the supervision of Prof. Dr. Stefan Szeider, and I succesfully defended my thesis on October 14th 2019.

Software

• QBF solver Qute ,which implements QCDCL with dependency learning and the reflexive resolution-path dependency scheme D^rrs
• The long-distance Q-resolution strategy extractor qrp2rup will be available soon. Please send me an email if you're interested in using it before it's properly published.
