Huddinge Municipality, Sweden Karolinska Institutet Full time

Position: Research Fellow in Structural Biology of Gamete Interaction

Are you passionate about advancing medical research?

The fusion of female and male gametes, namely egg and sperm, initiates the life of a new organism. Join the esteemed research team led by Professor Luca Jovine and engage in a multidisciplinary approach that combines molecular biology, biochemistry, and structural biology to illuminate a crucial biological event with significant implications for human reproductive health.

We are seeking two dedicated Postdoctoral researchers to become part of Professor Jovine's team at the Department of Biosciences and Nutrition. This department is located in a state-of-the-art biomedical research facility designed to foster creativity and collaboration across various scientific disciplines. For further insights into our department, please explore the Department of Biosciences and Nutrition.

Recent publications from our group include: Nishio et al. bioRxiv; Moi et al. Nat. Commun.; Stsiapanava et al. Nat. Struct. Mol. Biol.; Stsiapanava et al. EMBO J.; Nishimura et al. Nat. Commun.; Raj et al. Cell.

Candidate Profile:
We are looking for candidates who fit one of the following profiles, or ideally possess expertise in both areas:

(1) A highly motivated postdoctoral researcher eager to identify and characterize essential protein-protein interactions involved in gamete recognition and fusion across evolutionary species. Candidates should have substantial hands-on experience in mammalian and/or insect cell expression, purification, and biochemical analysis of proteins. Proficiency in analyzing protein-protein interactions through various techniques is essential, and experience in developing monoclonal antibodies will be considered advantageous. Familiarity with X-ray crystallography and/or cryo-EM, as well as knowledge of deep learning-based protein structure prediction, is highly desirable but not mandatory.

(2) A highly motivated postdoctoral researcher interested in uncovering the molecular mechanisms of egg-sperm interaction during fertilization by integrating cryo-EM and X-ray crystallography with AI-driven protein structure predictions. Candidates should have significant experience in experimental and/or computational structural biology focused on protein-protein interactions, particularly in biological systems involving membrane proteins. Previous experience in biochemically identifying and characterizing protein complexes, along with mammalian and/or insect cell expression, is also highly desirable. A first-author publication in a reputable international peer-reviewed journal, fluency in English (both written and spoken), a collaborative spirit, and a strong drive for scientific excellence are required.

Eligibility Criteria:
To qualify for the postdoctoral position, candidates must possess a doctoral degree or an equivalent foreign degree. This requirement must be fulfilled by the time of the employment decision. Candidates who have completed their doctoral degree within the last three years are preferred, although exceptions may apply under special circumstances.

What We Offer:
This role is a temporary postdoctoral contract for two years, with the possibility of extension based on funding availability.

You will work in a stimulating and inspiring environment with diverse expertise and interests. Karolinska Institutet is recognized as one of the leading medical universities globally. Here, you will collaborate with researchers across various specializations and methodologies, providing ample opportunities for knowledge exchange and interdisciplinary collaboration. The synergy of these collaborations has propelled KI to the forefront of global research. Many professionals in healthcare have been educated at KI, fostering a close relationship with healthcare providers to create groundbreaking education and research.

The KI Department of Biosciences and Nutrition promotes a highly international and collaborative atmosphere for biomedical research. The Jovine laboratory is equipped with cutting-edge technology for recombinant protein expression in mammalian cells, insect cells, and bacteria, as well as protein purification and characterization techniques. Additionally, access to advanced facilities for protein identification, posttranslational modification analysis, and quantitative proteomics is available.

Application Process:
Interested candidates must submit an application in English, including the following documents:
- A comprehensive resume detailing academic history, positions held, and distinctions
- A complete list of publications
- A summary of current research (maximum one page)
- A cover letter outlining motivation for joining the laboratory (maximum one page)
- Contact information for three references, including the Ph.D. thesis supervisor.
