Do you want to contribute to improving human health?

TheBaranello Lab: Drawing from our expertise in the fields of topoisomerase and cancer biology, we aim to answer fundamental questions about how transcription, replication and DNA topology are functionally coordinated in human cells. We use state-of-the-art approaches to assess transcriptomic, epigenomic and replisomic profiles, as well as bioinformatics, microscopy and drug screens to understand how topoisomerase regulation affects fundamental nuclear processes (key lab references: Baranello et al. Cell 2016; Wiegard et al. Molecular Cell 2021; Das et al. Molecular Cell 2022, Cameron et al. Sci. Adv. 2023). The overall aim is to reveal novel cancer dependencies and develop new anti-cancer strategies more specific towards tumor cells and with fewer side-effects.

We are a young and dynamic research team with a well-established collaborative network. The group is also associated to the laboratory of Prof. Shiraighe at University of Tokyo, Japan. The successful applicant will thus be part of multiple networks of recognized scientists. The group is located in the Biomedicum, top modern research building with a large repertoire of researchers and access to state-of-the-art infrastructure and facilities.

Description of the subject area

Topoisomerases are essential enzymes that regulate the topology of DNA favoring replication and transcription by cleaving/resealing DNA strands. Because cancer cells have higher rates of proliferation compared to normal cells, they are highly dependent on topoisomerase activity. Therefore, strategies to target topoisomerases could provide a mean to selectively affect cancer cells. The focus of our research is to understand how topoisomerases are regulated during nuclear processes to develop new ways to target these regulatory mechanisms and affect the viability of cancer cells.

Your mission

The selected candidate will play an important role in the development and management of scientific projects. Our recent articles show that topoisomerases execute their function through interactions with partner proteins that modulate their activity to affect transcription (Baranello et al. Cell 2016; Das et al. Molecular Cell 2022, Cameron et al. Sci. Adv. 2023). We use biochemical and molecular biology approaches, microscopy, single molecule tracking, DNA and RNA sequencing and CRISPR-based genome editing to investigate how topoisomerase dynamics within the nucleus control topoisomerase activity. This will inspire a new strategy to target topoisomerases in cancer therapy.

An ability to drive projects, experimentally and intellectually, is required. The successful candidate will be expected to assist doctoral and postdoctoral researchers with their projects, providing seniority and expertise to the group, as well as pursue an independent line of research.

The responsibilities and duty of the applicant include:

  • Keep updated of relevant scientific literature and contribute to the design and execution of experimental work.
  • Analyse data and interpret results.
  • Generate and assist in the writing of scientific texts, including research papers, reviews and grants.
  • Train and mentor team members.

Eligibility requirements

To be eligible for employment as a Research Specialist, in addition to holding a Degree of Doctor, PhD, or having equivalent scientific expertise, the applicant must have demonstrated research expertise as well as have documented research experience after defending their doctoral dissertation.

Competency in Cell and Molecular Biology is sought.

  • General to both specialties are possessing excellent verbal and written communication skills in English and ability to communicate with laboratory members and collaborators is required.


  • Proficiency in molecular biology methodologies (including RNA-extraction, RT-qPCR, Western blot, ELISA), DNA/RNA sequencing approaches, cell culture (cell lines and primary cells), imaging (including confocal and super resolution microscopy), single molecule tracking in live cells, flow cytometry/FACS, protein purification.


  • Expertise working with big data (generated by e.g. RNA-seq/ChIP-seq).
  • Experience in method development.
  • Experience writing research publications.

After an overall assessment of the expertise and merits of the applicants in relation to the subject area, Karolinska Institutet will determine which of them has the best potential to contribute to a positive development of the activities at KI.
