Seminars at Purdue

For several semesters I was the organizer of the Topology Seminar.
The schedule of those semesters can be found here.
The current schedule is on the department calendar and here.

The schedule for the Mathematical Physics Seminar can be found on the department calendar and here.

AMS Sectional Meeting

Member of local organizing committee for April 2020, subsequently moved online.

Midwest at Purdue

We co-organized the Midwest Topology Seminar Spring 2012 and the Midwest Topology Seminar Fall 2016

Quantum Science & Technology

Co--organizer and Session Chair at the International Symposium of Quantum Science & Technology at Purdue

Recent AMS special Sessions

Together with Sasha Voronov, we organized Special Session on Topology and Physics at the AMS meeting at the Minnesota Fall 2016 meeting.

With Emil Prodan and Birgit Kaufmann, we organized  Special Session on Topological Mathematical Physics at the Bloomington, Spring 2017 meeting.

Together with Martin Markl and Sasha Voronov, we organized a Special Session on Higher Structures in Topology, Geometry and Physics at the AMS meeting at the Purdue Spring 2020 meeting. The conference volume was just published as Contemp Math 802.

Together with M. Pflaum we organized the special Special Session on Geometry and Topology of Quantum Phases of Matter at the Spring Western meeting 2024 in San Francisco.

Trimester Program on Higher Structures in Geometry and Physics.

From Jan-Mar 2016, I co-organized the  Program on Higher Structures in Geometry and Physics at the Max-Planck Institute for Mathematics in Bonn. This also comprised several conferences:
Opening Conference,  HTT workshop with lectures by Vladimir Voevodsky and Closing Conference

Program and Workshop on  "Combinatorics, Resurgence and Algebraic Geometry in Quantum Field Theory"

Aug 2024. Co-organized with M. Borinsky, D. Kreimer and Karen Yeats + local organizers C. Blohmann and D. Prinz. This included a conference of the same name
