Postdoctoral Research Assistant Nanoscale Electrostatics and Biophysics

Grade 7:
Salary in the range of £39,424–£43,984 per annum, inclusive of a pensionable Oxford University Weighting of £1,730 per year. Full time (100% FTE), fixed term 3 years.

We are seeking a Postdoctoral Researcher to participate in research in the Quantitative Immunodynamics Laboratory led by Dr. Narain Karedla, as part of an ERC Starting Grant project MIETEN (Metal‑Induced Energy Transfer based Electrometry and Nanometry). In this role, you will contribute to the ERP‑funded MIETEN programme by developing and applying quantitative fluorescence microscopy and spectroscopy methods for single‑molecule charge measurements and nanoscale membrane electrostatics.

You will also adapt existing scientific techniques and develop new experimental techniques to investigate how molecular and membrane electrostatics regulate immune‑cell signalling and immune‑cell–target cell interactions, using engineered substrates, electroactive biointerfaces, and membrane‑mimetic systems. This position involves the use of specialist laboratory equipment, including advanced fluorescence microscopy and spectroscopy platforms such as the Pico Quant Luminosa, to generate, analyse and interpret imaging, fluorescence lifetime, single‑molecule, correlation spectroscopy and other biophysical data.

You will hold a PhD/DPhil (or near completion) in physics, biophysics, physical chemistry, nanoscience, bioengineering or a closely related discipline together with a strong background in quantitative fluorescence microscopy or spectroscopy, with experience in methods related to single‑molecule or membrane biophysics. You will have demonstrable experience in developing, fabricating and characterising engineered substrates, nanoscale devices, electroactive biointerfaces, thin‑film platforms for optical, electrochemical, or biological measurements.

You will also have the ability to design, plan, and independently manage academic research and associated activities, and evidence of research productivity appropriate to career stage, including publications, preprints, conference presentations, or other relevant research outputs. Experience with FCS, FLCS, single‑molecule fluorescence, super‑resolution microscopy, or photon‑counting/TCSPC methods is desirable.

• An excellent contributory pension scheme
• 38 days annual leave
• A comprehensive range of childcare services
• Family leave schemes
• Discounted bus travel and Season Ticket travel loans
• Membership to a variety of social and sports clubs

You will be required to upload a covering letter/supporting statement, CV, and details of two referees. Please quote 186733 in all correspondence. The closing date for applications is 12pm 3 July 2026. Interviews will take place during the week commencing 20 July 2026 and will be hybrid.
