Seeking new talents
We offer 13 PhD positions in our network. Apply today and build your future in the exciting field of novel enzyme research!
The call opens on 1. November 2025, with an application deadline of 31. December 2025.
1. Eligibility requirements:
All of our network institutions are equal opportunity employers that seek a diverse workforce in terms of age, culture, nationality, and gender. They will not apply restrictions based on gender, age, ethnic group, national or social origin, religion or belief, sexual orientation, language, disability, political opinion, or social or economic conditions.
If you want to join HaloVerse as a PhD student, the following eligibility criteria apply:
- At the time of recruitment by the host, you are within the first four years (full-time equivalent research experience) of your research career and do not hold a doctoral degree.
- You have not resided or carried out the main activity (e.g. work, studies) in the country to which you would like to be recruited “for more than 12 months in the 3 years immediately before the recruitment date” (mandatory to provide supporting documentation proving the place(s) of residence or work during the previous 3 years). This only applies to the country in which the candidate is recruited, not the country with which the double degree is arranged.
- You are in position of enrolling in a doctoral programme at the country and meet the specific eligibility requirements at the hosting institution, if applicable. Note: the mobility rule is applied to the first recruitment within the project, not to secondment periods. Mobility rules are applied to the residence and not to the nationality.
- You are able to speak and write the English language fluently.
- You submit a complete application within the submission deadline through our application form.

2. How to apply:

You can apply for any of our projects using the application form that opens when you click on the “Apply here” button below each position. Please note that you may apply for one to three positions. You should apply for each position and explain in the motivation letter your choice; the preferred position needs to be indicated. Please note that you must submit all applications via this form. We cannot attend to any requests addressed directly to any of the beneficiaries.
In the application form you should provide:
- Personal information such as your first and last name, nationality and contact details.
- Curriculum vitae, including a publication list
- Motivation letter (maximum two pages), which should highlight your research experience and academic achievements, explain your interest in the project, and, if applicable, explain why you are applying to more than one project.
- A scanned copy of certified academic records. These documents must show the grades attained in exam periods and evidence that the required degree will be obtained by the expected time of recruitment if it has not already been awarded. In addition, the document should indicate a description of national grades.
- Any additional files relevant to the application.
- The contact of at least one university lecturer or scientist who are familiar with your academic work and who can judge your potential as a predoctoral researcher. Applicants will be responsible for ensuring that referees submit these letters.
- A summary of any work experience.
