The Catalyst hosts weekly improvisation sessions designed for the scientific community. We also offer a variety of workshops that teach theater and speaking skills to scientists or other groups.


Weekly Drop-in Improvisation 

Drop-in sessions are organised so that participants can simply 'drop-in' and experience improv. These sessions are a great opportunity to develop your improv skills in a relaxed atmosphere and are for all skill levels.

Drop-ins are now hosted at the following locations:

University of Lausanne, Genopode Building, Room 2020
Wednesdays, 18:30 - 20:00

Wednesdays, 19:00 - 20:30

Drop-in is also an opportunity to socialise with other like-minded people. After each drop-in session the group heads to a local restaurant on the EPFL campus or in the centre of Lausanne to share dinner, thoughts, and banter.

Send an email to improv AT thecatalyst DOT ch if you are in doubt. 

Join our facebook groups for consistent banter. Click here for The Catalyst (Lausanne) or here for Catalyst-Geneva (Geneva).


If you just want to try it out, your first time to the drop-in is free. After that, each drop-in you attend without becoming a Catalyst member will cost you 5 CHF to be paid to that day's leader.

Becoming a Catalyst member will give you access to all weekly drop-ins and our less frequent workshops with fancy improvisors and theater people. The Catalyst Membership fee for one academic year (Sept 1 - August 31) is 50 CHF. Alternatively, you can also be involved on a term-by-term basis for 30 CHF per term (terms run from Sept 1-Feb 28/29 & March 1-August 31).

To become a Catalyst member, fill is the form you will find here: https://thecatalyst/form/.

Please transfer the desired amount with your name and 'membership' in the comments.
