Postdoctoral Research Associate in Single Molecule Analytics

Department of Chemistry, Chemistry Research Laboratory, 12 Mansfield Road, Oxford, OX1 3TA.

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.

The group is looking for a highly motivated and driven postdoctoral researcher with a strong interest in single molecule measurements to contribute strongly to a wave of ongoing developments deploying the escape-time technology on a broad range of measurement problems in biology. This position 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 recently obtained 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.
