Seminars, reading groups, colloquia:

Together with Bruno Teheux, we organize Mulitplicities. Talks are for all mathematicians and chosen to illustrate the diversity of mathematics and mathematicians.

Together with Jean-Marc Schlenker and Bruno Teheux, we are organizing the MAST lecture series at the University of Luxembourg that is a collection of math talks (close to a traditional colloquium) and talks about mathematical interactions with other areas.

The Geometry and Topology seminar generally takes place on Monday.

This webpage has a list of activities related to the "low dimensional geometry and topology hub" of the department and this webpage lists other events organized at UL.

Conference organization (coming up):

As an external member of the scientific committee, I'm participating in the French Computational Geometry Days which will take place at the CIRM in March 2020.

Conference organization (done and dusted):

Together with Binbin Xu, we organized the Lost in Translation Surfaces workshop in Luxembourg. It took place Jan. 29-31, 2020 and was organized in the framework of the SoS project supported by an ANR-FNR grant.

Together with Add Jaipong, Sam Kim, Chris Leininger, Jean-Marc Schlenker, Ser Peow Tan and Tengren Zhang we organized a workshop on Combinatorial and algebraic aspects of geometric structures at Chiang Mai University in Thailand which will take place in July 2019.

Together with Florent Balacheff, Gil Solanes and Kroum Tzanev we organized a workshop on Multiple Perspectives on Geometric Inequalities at the CRM (Barcelona) in June 2019. This was preceded by a week of Advanced Courses (also at the CRM) and is part of a whole semester of activities.

I organized the yearly SoS meeting meeting in Luxembourg in November 2018.

Together with Viveka Erlandsson, Youngju Kim, Dragomir Saric, Perry Susskind, and Rob Suzzi Valli, we organized a GEAR Regional Workshop on Geodesics on hyperbolic manifolds and related topics at Connecticut College in August 2018.

Together with Jean-Marc Schlenker and Ser Peow Tan, we organized a Workshop on geometric structures and representation varieties at the National University of Singapore in May 2017.

Together with Stefan Wenger, we organized a small lecture series at the Math Department of Fribourg in June 2015.

Together with Ara Basmajian, we organized a Workshop on Identities at the Graduate Center (City University of New York) in April 2015.

In March 2014 I co-organized a Swiss Doctoral School Conference (CUSO) in the Swiss Alps:
Quadratic forms, lattices and applications

In November 2011, at the Centro Stefano Franscini we held:
The hyperbolic and Riemannian geometry of surfaces and other manifolds
