About this position
Postdoctoral opportunity at the Aragón Institute of Engineering Research (I3A), University of Zaragoza, Spain, for a researcher with strong expertise in aptamer identification by SELEX. The project is centered on the discovery of first-in-class therapeutic molecules for cardiac disease, with aptamers used both as active pathway modulators and as targeted delivery vehicles.
The work combines functional screening in advanced human in vitro models, including heart-on-chip platforms, within a multidisciplinary environment spanning molecular biology, stem cell-based tissue engineering, advanced in vitro models, and translational research. The position sits in the laboratories of Dr. Laura Ordovás and Dr. Jesús Ciriza at I3A, a leading institute with state-of-the-art infrastructure at the interface of engineering and biomedicine.
This postdoctoral role is designed for candidates who intend to apply to competitive fellowship schemes, specifically Juan de la Cierva 2026 and the EMBO postdoctoral program. The institute offers full institutional support for preparing applications, access to organ-on-chip and advanced human in vitro platforms, and opportunities to develop scientific independence, contribute to grant proposals, and supervise students and junior researchers.
Eligibility highlights include a PhD in Molecular Biology, Biochemistry, Biotechnology, Biomedicine, or a related area, a strong publication record, excellent written and spoken English, and direct practical experience with SELEX methodologies such as cell-SELEX and/or in vivo SELEX. For EMBO, the posting also notes requirements related to the timing of the PhD, first-author publication record, and international mobility. The application deadline listed is 2026-10-09.
To apply, candidates should email a CV with publication metrics, a motivation letter, and contact details for two references to the listed contacts at the University of Zaragoza.
