Doctoral researcher (m/f/d/x) in microbial systems biophysics

The new doctoral researcher is to investigate how the gut bacterium *E. coli* navigates mechanically complex environments that mimic properties of its natural habitat. Properties of both the bacteria and the environment will be modulated in a controlled fashion to identify the underlying physical mechanisms and address the following questions:

• What is the relationship between behavioural and material parameters that enable optimal navigation?
• Is optimal intracellular information processing specific to the type of environment?
• How do bacteria navigate mechanical gradients?

## The role

• Independent, original, experimental scientific research on the above project
• Additional scientific qualification (preparing a doctoral thesis)
• Thorough documentation of research
• Publication of research results, for example at conferences, workshops, or in scientific articles
• Contributions to the Institute’s teaching responsibilities

## About you

• An excellent scientific university degree (master of science or comparable) in (bio-)physics, (bio-)engineering or a related field
• Very good command of at least one programming language (Matlab or Python preferred) and of quantitative scientific data analysis
• A track record of academic excellence (e.g. very good grades in the course of study, research or study scholarships and prizes, scientific publications)
• Written and spoken professional fluency in English (at least equivalent to level B2)
• Excellent written communication skills, demonstrated through coherent, structured and precise writing
• Experience with microscopy and scientific image processing would be an advantage
• Interest in quantitative experimental interdisciplinary science
• Collaborative mindset and teamwork skills

## What we offer you

• a varied role with a high degree of responsibility in the dynamic environment of a major university
• a professional English-language work environment at the leading edge of interdisciplinary science
• Collaboration in a friendly, supportive and motivated team
• flexible working hours and mobile working to support work-life balance
• Goal-oriented staff development throughout your working life, with opportunities for continuing professional development
• a wide range of occupational health management services
• Remuneration in line with the collective bargaining agreement of the federal states (TV-L), including an annual special payment and occupational pension scheme
• excellent transport links and the option to purchase a discounted public transport ticket, such as the Deutschlandticket as a commuter pass
• a wide range of food options in the refectories and cafés operated by Studentenwerk Leipzig.

Leipzig University aims to increase the proportion of women in positions of responsibility and therefore expressly invites qualified women to apply. Severely disabled persons – or persons deemed legally equal to them under Book IX of the German Social Code – are encouraged to apply and will be given preference in the case of equal suitability. If you have any questions about accessibility or need assistance with this application process, please contact Leipzig University’s disability officers at: [](https://mailto:).

## Have we sparked your interest?

Please submit your application in English addressed to **Fakultät für Physik und Erdsystemwissenschaften, Herrn Dekan Professor Dr. Johannes Quaas by 1 November 2026** via our online application portal.
