Peter Adams is a lecturer on a University Academic Fellowship position and part of the Molecular and Nanoscale Physics group (2015-current). This followed a Postdoctoral Research Scholar position at Los Alamos National Laboratory, USA (2012-2014), and PhD and BSc at University of Sheffield, UK (2004-2007; 2007-2011).
My research investigates membrane protein and lipid assembly, with a focus on the specialized membranes involved in photosynthesis. I wish to understand, mimic and control the organization of semi-synthetic membranes, inspired by chloroplasts light-harvesting membranes.
All biological cells, from bacteria to human epithelia, are surrounded by membranes comprised of lipids, proteins and other molecules. Biological cell membranes rely upon complex, hierarchical organization to elicit functional responses. To achieve specialized function some membranes form organized domains of protein proteins and multilamellar stacked arrangements, such as those found in the certain membranes involved in photosynthesis ('light-harvesting' membranes). Synthetic biology often uses genetic engineering or de novo chemical synthesis to develop minimal and/or modular systems of DNA, peptide sequences or organic molecules than can perform novel functions. Instead, in our research, we use purified LH proteins and natural lipids as building blocks to generate model protein/lipid systems. We use these controlled model membranes as a platform to test the factors influencing self-assembly, organisation and function in biological membranes, over multiple scales. We take a multi-disciplinary approach combining aspects of surface chemistry, nano/micro fabrication, protein biochemistry, spectroscopy and various microscopies to fully explore these membranes. Long term goals include: (i) to mimic the natural stacked membrane systems to provide a controlled platform for understanding the assembly and biophysical properties of the membrane protein/lipids, (ii) to design new 3-D patterns of membranes onto solid surfaces with preservation of biological functionality, (iii) to better understand the process of photoprotection in plants (Non-Photochemical Quenching).
Various techniques are used to fully characterize the proteins, membranes and new devices from the micro- to the nanoscale. These include atomic force microscopy, electron microscopy fluorescence microscopy, spectroscopy, DLS, QCM, etc. We are always looking towards the latest, state-of-the-art technologies to enable the next breakthrough. Success in these efforts will represent a major advance in the controlled design of 3-D complex, functional biomaterials.
