Project 1: Single-molecule dissection of mitochondrial, bacterial and chloroplast electron transfer complexes with atomic force and cryo-electron microscopies

Prof Matt Johnson (Sheffield), Prof Jamie Blaza (University of York), Dr Andy Hitchcock (Sheffield)

How does life move electrons? Every breath you take, and every calorie a plant captures, depends on electron-transfer reactions between tiny mobile carrier proteins and the large membrane machines of respiration and photosynthesis. Many of these machines cluster into ‘supercomplexes’, and cells that cannot form them are less fit, yet why supercomplexes matter has remained a mystery, because conventional methods only measure averages over billions of molecules.

This PhD will change that. Using a newly developed single-molecule atomic force microscopy technique, together with fluorescence and absorption spectroscopy and cutting-edge cryo-electron microscopy, you will watch individual carrier proteins meet, bind and hand over electrons to their partner complexes, one encounter at a time. You will build novel supercomplexes in the alga Chlamydomonas reinhardtii and the bacterium Rhodobacter sphaeroides using CRISPR genome editing, then ask whether re-arranging these machines can make electron transfer faster and more efficient.

You will be trained across biophysics, structural biology, biochemistry and molecular genetics, working between the Sheffield Photosynthesis Research Group (Prof. Matt Johnson and Dr Andy Hitchcock) and the York Structural Biology Laboratory (Prof. Jamie Blaza), with access to world-class single-molecule and cryo-EM facilities. You will join a large, diverse and supportive research community, present at national and international meetings, and complete a professional placement (PIPS).

The work addresses fundamental questions about the rules of life while pointing towards real-world applications: new antibiotic and therapeutic targets, more productive crops, and light-powered cell factories for fuels and medicines. We are looking for a curious, motivated student, excited to master state-of-the-art tools and to answer one of the longest-standing questions in bioenergetics: what supercomplexes are actually for.

Project 2: Designing de novo protein biomaterials for solar energy capture and quantum sensing

Prof Jenny Clark (Sheffield),  Dr Andy Hitchcock (Sheffield)

Photosynthesis is one of nature’s most successful processes, efficiently capturing sunlight and converting it into useful energy. Recent breakthroughs in artificial intelligence now make it possible to design entirely new proteins from scratch, opening exciting opportunities to create biological materials with novel functions.

This PhD project will combine machine learning protein design, synthetic biology, and advanced spectroscopy to develop a new generation of artificial light-harvesting proteins. Building on recent breakthroughs in de novo protein design and biomolecular modelling, the project will use state-of-the-art tools such as RoseTTAFold, RFdiffusion, AlphaFold 3, and LigandMPNN to create proteins that bind natural and synthetic pigments with tailored optical properties (1-3).

The student will design, produce, and characterise new protein-chromophore complexes, investigating how protein structure controls energy transfer, fluorescence, and other photophysical processes. The project combines computational design with experimental work, including protein engineering, spectroscopy, mass spectrometry, and ultrafast laser techniques. There will also be opportunities to develop biohybrid materials by integrating engineered proteins with organic semiconductor chromophores.

This is a highly interdisciplinary project suitable for students interested in structural biology, synthetic biology, biophysics, photochemistry, or materials science. The successful candidate will receive training in cutting-edge computational methods, molecular biology, and advanced spectroscopic techniques while working within a collaborative research environment spanning biosciences, physics, chemistry, and engineering.

This project will provide new insights into how nature harvests light, and may contribute to future applications in sustainable energy, biotechnology, biosensing, and advanced photonic materials. The student will join an internationally connected research team with expertise in protein design, photosynthesis, spectroscopy, and biomolecular engineering, offering opportunities in many biotech applications.

Project 3: Imaging the ionic landscape of a living cell: how Chlamydomonas coordinates photosynthesis, carbon fixation and respiration

Prof Jamie Blaza (University of York), Prof Luke Mackinder (University of York), Prof Matt Johnson (Sheffield), 

Are you fascinated by how life powers itself and grows at the nanoscale? This PhD offers an exceptional opportunity to investigate the 'ionic landscape' of the model alga Chlamydomonas reinhardtii using state-of-the-art cryo-EM and specialised ‘focused ion beam’ technology that subjects nanometre-sized volumes in the cell to detailed mass spectrometric analysis, called ‘cryo-FIB-SIMS’ (Ochner et al, Nat Methods, 2026).

In this project, you will pioneer a transformative approach, mapping the distribution of ions between organelles, within living cells, in different growth modes. You will reveal how organelles coordinate carbon fixation, photosynthesis and respiration to balance the cell’s energy demands. And you will obtain insights into how Chlamydomonas is such a powerful organism for green biotechnology, informing efforts to engineer algae for more efficient biofuels and carbon capture applications.

This PhD is highly interdisciplinary, bridging biophysical imaging with algal cell biology. You will gain hands-on expertise with cryo-FIB-SIMS, volume imaging, and high-resolution cryo-ET. Developing a unique skill set at the intersection of biophysics and cell biology will equip you for a career in academia or the rapidly evolving biotechnology sector.
