Postdoctoral Fellowship

Applicants are required to get in touch with our staff members to discuss their support of the
application and to discuss a research project and implementation plan (theory, observation,
and data analysis are all welcome). A list of supervisors for hosting postdoctoral fellows in
2026 is provided below.
Only applications that have been discussed with supervisors will be considered. Supervisors
are expected to make their private shortlists and only recommend the final submission to the
most promising applicants.
Deadlines:
1. Get in touch with the selected supervisor before March 27, 2026. Later enquiries may
not be accepted.
2. Application Deadline is April 13, 2026, 12 PM (noon; in CEST/UTC+2 timezone).
Submissions by email to [email protected] with the subject POSTDOC 2026.
Required application parts (all in PDF):
- cover sheet listing: full name, birth date, nationality, current position, the exact date of PhD
defence, name of the host/supervisor at ASU, short motivation (½ page max)
- curriculum vitae
- list of publications including citations
- summary of the most significant research results achieved to date and proposed research
project (2 pages max in total)
- outline of the implementation plan for 2 years (4500 characters max)
- recommendation letters (to be delivered separately)
Applicants must arrange for a minimum of two recommendation letters to be sent directly to
the same electronic address as above. The letters may be issued up to 9 months before the
application deadline.
Applications can be submitted slightly before finishing a PhD, in which case a statement from
the current supervisor stating the planned date of the defence should be included. Applicants
MUST then prove they have been awarded the PhD degree before April 20.
The appointment is initially for one year; an extension for another year is expected upon
satisfactory scientific performance. A necessary condition is to satisfy legal requirements for
employment in the Czech Republic (EU member state). Salary will be based on the domestic
level (cca 1800 EUR/month before taxes (~25%); health insurance is included in the taxes).
There is a possibility of staff accommodation in Ondrejov; in Prague, private accommodation
has to be arranged. The starting date of employment is expected to be July 1, 2026, but it is
negotiable.
