Dr. Jobst Heitzig

Dr. Jobst Heitzig holds a PhD in mathematics from Hannover University and has worked as a scientific officer with the German National Statistical Office, as a data warehouse analyst with the German Development Bank KfW, and as a freelance statistical software trainer with SAS. Since 2010 at PIK, he was a project lead of an EIT Climate-KIC project on Power Grid Stability (SWIPO), co-speaker of the flagship project copan – coevolutionary pathways, and has organized several interdisciplinary international workshops and conferences.

Group decisions, cooperation, game theory

• Efficient democratic decisions via nondeterministic proportional consensus (working paper, social app, seminar talk video, PIK-internal lecture video)
• Bottom-Up Formation of a Global Climate Coalition of Farsighted Strategic Players (CFCC15 poster, conference paper, slides for Oslo working group, DPG poster, GAMES2012 poster, theory paper)
• Heitzig J, Lessmann K, Zou Y (2011) Self-enforcing strategies to deter free-riding in the climate change mitigation game and other repeated public good games. PNAS 108:15739–15744. doi:10.1073/pnas.1106265108 (Press release, Commentary, Guardian article, Huffington Post article, Climatewire article)
• Some chance for consensus (Soc Choice Welf, 2010)
• Interdisciplinary approaches to cooperation (book chapter)

Development of data analysis methods

• Moving Taylor Bayesian Regression (MoTaBaR)
• Study of climate data using...
• non-linear time-series analysis
• complex networks
• how to deal with nodes of different size (slides)
• example (download this and open in g**gle earth!)

Dr. Heitzig has published on game theory, complex networks theory, dynamical systems theory, environmental economics, social choice, statistical methods, general topology, confidentiality protection, combinatorics, and environmental ethics, and has edited two special issues for the journal EPJ ST.

• according to the Mathematics Genealogy, my almost complete lineage is:
  Nicolaus Copernicus → Georg Joachim von Leuchen Rheticus → Valentin Otto → Melchior Jöstel → Ambrosius Rhodius → Christoph Notnagel → Johann Andreas Quenstedt → Michael Walther Jr. → Johann Pasch → Johann Andreas Planer → Christian August Hausen → Abraham Gotthelf Kästner → Georg Christoph Lichtenberg → Johann Tobias Mayer → Enno Heeren Dirksen → Carl Gustav Jacob Jacobi → Emmy Amalie Noether → Max Deuring → Max Koecher → Marcel Erné → Jobst Heitzig, which is by no means special since in their database almost 2/3 of all mathematicians go back to Copernicus!
