Francesca was a PartII student and joined us in the 2021/22 academic year. We are delighted to welcome her back as a Dphil. Her project focuses on developing and refining experimental and analytical workflows for affinity-based mass photometry: a novel, single molecule-based method that can detect and measure the mass of specific proteins of interest, directly from lysed cells and homogenised tissues. Combining affinity-based mass photometry with mass spectrometry-based proteomics will enable us to detect, characterise and quantify specific protein interactions under conditions that closely mimic the native cellular or tissue environment.
