International and Diverse Scientific Community
Our scientists, from professors to postdocs to students, hail from all corners of the world, representing over 80 different nationalities, and build on research and degrees earned from the finest global scientific institutes and universities.

English-Speaking
We use English throughout the Institute as the language of instruction and communication.

Interdisciplinary
 Our Graduate Program is characterized by modern comprehensive training with a special interdisciplinary focus.

Cutting-Edge Research Training
Students work closely with outstanding faculty within small research groups and have access to first-rate facilities. Students spend the first year completing coursework and rotations before affiliating with a group.

This first phase of exploration allows students to ensure that the research topic, as well as the research group, are the best match for them before embarking on in-depth thesis research in the second phase.

Entry with a Bachelor's or Master's Degree
We welcome students with a Bachelor’s or a Master’s in science to apply for our PhD program.

Funding
All PhD students are offered 5-year contracts. All students making reasonable progress are fully funded until the time of their thesis defense.

ISTA relies on diverse funding sources to support all its researchers. Our Grant Office supports ISTA scientists who would like to apply for external funding. Students also receive financial support to attend scientific conferences and workshops.

Careers
Our distinguished alumni have gone on to successful careers after their PhD studies at ISTA.

PhD students receive support through our mentorship and career development programs which focus on training in transferable skills for academia and beyond. Throughout their studies, PhD students are supported by Career Services, which provide career development advice and training.

We also provide xista, an in-house science venture that supports researchers in the commercial development and use of their research results.
