Overview

Institute of Biotechnology of the Czech Academy of Sciences announces an open competition in accordance with the Act No. 283/1992 Coll. on the Czech Academy of Sciences, and the Statutes of the Czech Academy of Sciences for a position:

Postdoctoral Researcher in Dynamic Control of Ciliary Transport

The Institute of Biotechnology (IBT) invites applications for a postdoctoral position in the newly established Laboratory of Intracellular Dynamics led by Aniruddha Mitra, PhD. The lab investigates molecular mechanisms by which the cytoskeleton and motor proteins organize the interior of cells into specialized compartments, with a particular focus on protein sorting and transport within sensory cilia of C. elegans neurons.

The position is for you if you:

… want to work with C. elegans to address mechanistic questions in ciliary biology

… are motivated by advanced imaging and quantitative analysis in living organisms

… are interested in developing genetic and optical tools to probe molecular dynamics in vivo

… enjoy combining careful experimental work with critical mechanistic thinking

…are motivated by independence, responsibility, and the chance to build something new

About the role

The postdoc will establish and optimize the auxin-induced degradation (AID) system in C. elegans to enable precise temporal control over ciliary protein activity. This dynamic manipulation will be used to probe the functional roles of intraflagellar transport (IFT) components and ciliary membrane proteins, linking their single-molecule dynamics to changes in ciliary architecture and function.

The successful candidate will work at the interface of molecular biology, quantitative imaging, and biophysics, developing transgenic worm strains, integrating AID with advanced fluorescence microscopy and collaborating with theoretical biophysicists to model IFT dynamics.

Key responsibilities

  • Develop and optimize the AID2 system in C. elegans to control ciliary protein levels with spatial and temporal precision
  • Design and generate transgenic worm strains using CRISPR/Cas9 and MosSCI
  • Use advanced fluorescence microscopy to quantitatively image ciliary protein dynamics in living C. elegans while inducing rapid changes in protein function
  • Collaborate with team members and theoretician collaborators to link experimental results with quantitative modelling of IFT
  • Contribute to manuscript preparation, grant reporting, and supervision of students in the lab
  • Present research findings at national and international conferences

Desired skills and experience

  • PhD in molecular or cell biology, genetics, biophysics, or a related field (completed or near completion)
  • Experience in C. elegans genetics and transgenesis, with molecular cloning expertise desired
  • Hands-on experience in fluorescence microscopy and quantitative image analysis
  • Excellent written and spoken English, and good communication skills for collaborative work

Attitude and drive

We are looking for a curious, inventive, and hands-on scientist who enjoys bridging molecular biology, imaging, and image analysis. You should be independent yet collaborative, excited to build new tools and test ideas rigorously. A strong sense of initiative, precision, and perseverance in experimental work, combined with an open and constructive mindset, will be key to success in this position.

Preferred start date: February 2026 (negotiable)

Application deadline: 15th December 2025

We offer

  • Full-time position (1 FTE) for one year, renewable up to four years
  • Stimulating, international, and interdisciplinary environment within BIOCEV Center, a research center hosting over 50 research groups and state-of-the-art core facilities (imaging, genomics, proteomics, animal facility, etc.)
  • Involvement in top-level scientific research infrastructure
  • Competitive salary commensurate with experience and Czech Academy of Sciences standards
  • 5 weeks of vacation
  • Meal allowance
