Postdoctoral Research Associate in Single Molecule Analytics Full-time

Postdoctoral Research Associate in Single Molecule Analytics

The Krishnan Lab works in the broad area of soft condensed matter at the nanometer scale and has a long-standing interest in measuring and understanding the properties and interactions of molecular-scale matter, e.g., biological macromolecules. Recently the group pioneered “molecular stereometry” – a new experimental approach to measuring a molecule's size and shape in the solution phase (Science, 2025). Our microchip-based escape-time technology platform now enables measurements of the physical properties of macromolecules such as their electrical charge, size and 3D conformation with unprecedented precision, one at a time and in real time (Nature, 2010; Nature Nanotechnology, 2012, 2017; Science, 2025). The project involves a combination of optical imaging, nanofabrication, data analysis, and biochemical familiarity and experience.

We are looking for a highly motivated and driven postdoctoral researcher with a strong interest in single molecule measurements to join the group and contribute to a wave of ongoing developments deploying the escape-time technology on a broad range of measurement problems in biology. This role requires expertise in single molecule fluorescence experiments: specifically, experience and a strong interest in instrumentation, focusing on building or modifying experimental set-ups for optical imaging. Experience and interest in data analysis and the ability to perform basic biochemical work with proteins and DNA will be highly rated in the selection process. The ideal candidate will have a PhD in physics, biophysics, biochemistry, physical chemistry, engineering, or a related area, or have submitted a PhD thesis prior to taking up the appointment.

Applications for this vacancy are to be made online and you will be required to upload a supporting statement and CV as part of your application. In your supporting statement (<5 pages**)**, please explain how you meet each of the selection criteria found in the job description. Certificates, references and research papers should not be provided at this stage. The closing date for applications is 12.00 midday, Thursday 30 July 2026, UK time. Interviews will be held as soon as possible thereafter. This position is being re-advertised. Applicants who applied previously need not reapply unless they wish to submit updated information. The University of Oxford and The Department of Chemistry are Silver Athena SWAN holders. Applications are particularly welcome from women and black and ethnic minority candidates, who are under-represented in Chemistry research posts in Oxford.
