ICFO is offering two PhD positions to highly motivated students who wish to start their scientific career in a friendly and stimulating environment. The successful candidates will be joining the Attoscience and Ultrafast Optics group led by Prof. Dr. Jens Biegert.
Our PhD-program brings together top-level training and teaching for young scientists, benefiting from the extensive course offerings of local universities and focused instruction by ICFO professors, in a stimulating, international and interdisciplinary environment. PhD-students have the opportunity to take advantage of our network of excellence, consisting in partners of national and international research institutes and universities, as well as industrial partners in the field.
The successful candidate will be joining the Attoscience and Ultrafast Optics group led by Prof. Dr. Jens Biegert. The group works in a highly interdisciplinary field which fuses ultrafast laser physics, extreme nonlinear optics, atomic and molecular physics, SXR spectroscopy, X-ray optics, UHV technology, and electron-ion coincidence imaging techniques.
Main Tasks and Responsibilities
The selected candidates will apply, and further develop, attosecond spectroscopy to reveal many-body dynamics in materials and/or molecular systems to understand what causes matter to change its phase. In practice, this means applying attosecond soft x-ray spectroscopy to study matter in non-equilibrium conditions, defining new observables, and applying data-driven analysis to distinguish coherent response from fluctuations, correlations and phase-transition dynamics.
Main tasks and responsibilities:
- Operation of a world-leading attosecond soft x-ray beamline.
- Conduct pump-probe, temperature-dependent and phase-transition measurements on selected materials and samples with it.
- Establish calibrate, curate and analyze large datasets using reproducible workflows, clear meta data, version control and well-kept electronic documentation.
- We require appropriate work ethics and communication in a team.
- Follow laser, vacuum, cryogenic/electrical and sample-handling safety procedures; maintain clean, reliable shared-lab conduct.
- Work diligently and independently while communicating openly, documenting setbacks as well as results.
- Engage actively in the full scientific process, from careful experimental work and data analysis to the communication of results through publications, conferences, and internal group discussions. The emphasis is on rigorous, reproducible science.
Eligibility
To be eligible for the position, candidates must:
- Have an internationally-recognized Master-equivalent degreepreferably in physics. The degree must be completed by the start of your prospective PhD at ICFO, at the latest, and must be in a field of science and engineering related to the ICFO research activities. Degrees issued within the European Higher Education Area (EHEA) must have an equivalent to 300 ECTS, out of which a minimum of 60 ECTS must have been obtained in postgraduate studies. Please, if in doubt regarding your academic eligibility, contact us at [email protected]
- Candidates who have already been awarded a PhD are not eligible to apply.
- Have an excellent academic record, previous research experience and a strong commitment for scientific research.
Have a high working knowledge of English.

ICFO is an equal opportunity employer. Candidates are selected exclusively on merit and potential on the basis of submitted application material. No restrictions related to disabilities, citizenship or gender apply to ICFO positions. ICFO abides by the principles of openness, efficiency, transparency, supportiveness, and international comparability as stated in the European Charter for Researchers and the European Code of Conduct for the Recruitment of Researchers.
Candidates with disabilities or other special needs are strongly encouraged to apply to the program. ICFO will provide all possible assistance to ensure the candidate’s application is fairly assessed.
Candidates who have extenuating circumstances that may explain gaps in the academic career or other potentially negatively evaluated aspects of their application are invited to volunteer, if they wish, personal information that the selection panel may consider in their evaluation. Such information may include details of family obligations, severe illness or disability, refugee situation, etc. If the selection panel decides to shortlist a candidate based in part on such extenuating circumstances, it may require the candidate to provide reasonable supporting documentation.
Conditions
ICFO PhD positions are offered for a period of 4.5 years. The conditions of the positions awarded in the scope of the ICFO PhD fellowship program are as follows:
- Initial contract for a period of up to 6 months (referred to as the “initial trainee period”), while being pre-admitted to the PhD program, with an explicit follow-up/ renewal procedure at the end of this first stage. Note that in certain circumstances the initial trainee period might be shortened or not offered. During this period, students already take part in the ICFO working environment, join a research group, and work with their supervisor to define a research project.
- After the initial training period, students are formally enrolled in a PhD Program with a local university (as a general rule, the UPC PhD in Photonics program administered by ICFO), and the full PhD Fellowship activated. Fellowships are offered for periods of three years, renewable for an additional fourth year, and are formalized via a PhD-contract. Continuity and renewal are subject to satisfactory performance in the PhD studies and related research activities, evaluated annually by the Thesis Director and the ICFO PhD Committee.
- ICFO offers a standard salary level for PhD Students of €27.257,83 gross annual salary. This applies to both the 6-months Trainee Period and the 4-years PhD Period.
- The starting date will be discussed with the Group Leader by selected candidate.
- All fellowships include medical care coverage and work accident insurance through the Spanish Social Security system, providing access to the Spanish public health care system.
- As part of the fellowship, ICFO will provide budget as deemed necessary and with the corresponding approval from the corresponding Group/Team Leader to enable the PhD fellow to complete his/her assigned research project. This budget is managed by the Group/Team leader, and will include consumables and other materials, training and other related costs, such as registration fees, travel and subsistence costs for participation in national or international events, conference, meetings, schools, and/or other training activities.
Additionally, a family allowance is also available on request and after corresponding approval for people with family charges in the terms described in the corresponding policy.
