Present members

The group currently consist of 15 members – Details and biographicals below:

Professor Simon Newstead

Simon Newstead holds the David Phillips Professorship of Molecular Biophysics and is Theme head for Structural Biology & Molecular Biophysics in the Department of Biochemistry at the University of Oxford, a member of the Kavli Institute for Nanoscience discovery and a Professorial Fellow at Corpus Christi College

Dr Jo Parker: Senior Scientist

Jo is a senior scientist in the group and currently Co-Investigator on an MRC funded grant to understand the molecular basis for nucleotide sugar transport in health and disease. Targeting glycosylation is a promising avenue for the development of new and urgently needed anti fungal medications. Previously Jo was a Principle Scientific Officer at Cancer Research UK’s Clare Hall laboratory where she developed biochemical assays to understand pathways linked to DNA damage tolerance.

Dr Gabriel Kuteyi: Research Scientist

Gabriel joined the group in 2014 after completing his PhD with Professor Roslyn Bill at Aston University in Birmingham. Gabriel is currently the manager of our tissue culture suite and researchers novel methods for eukaryotic membrane protein production. He works on several projects supporting protein production and QC.

Dr Jonathan Goult: Research Associate

Jonathan joined the group in 2021 as a post-doctoral research associate funded by (Wellcome) and is currently investigating proton coupled transporters, and their role in health and disease. Jonathan completed his DPhil at the University of Oxford in the Kleanthous group researching bacterial protein antibiotics that specifically target multidrug resistant P. aeruginosa

Dr Oliver Adams: Research Associate

Oliver joined the Newstead lab in 2017 as a BBSRC Interdisciplinary Biosciences DTP student researching the structural characterisation of transporters involved in infectious disease, especially those from M. tuberculosis. In 2021 Oli joined the group as a Research Associate researching proton coupled transporters in health and disease.

Mr Daniel Frey: Wellcome Trust Structural Biology DPhil student

Daniel is a Wellcome Trust-funded DPhil student in Cellular Structural Biology that joined the Newstead group in 2020. His research focusses on elucidating the structural nature of KDEL receptor-cargo complexes. Previously, he conducted his B.Sc. and M.Sc. studies in Biochemistry at the Technical University of Munich and computationally studied proton transfer in cytochrome c oxidase in the lab of Ville Kaila at Stockholm University during his M.Sc. thesis project.

Dr Dimitris Kolokouris:Research associate

Dimitris is a Post-doctoral research associate, having completed his DPhil degree with the group in 2023. His undergraduate studies are in Pharmacy (M.Pharm) specialising in medicinal chemistry and he is a registered pharmacist by the Ministry of Health in Greece. Dimitris’ current research focuses on the regulation of transport activity and the structural basis for amino acid transport in the cell.

Mr Mark Löbel: Biochemistry DPhil student

Mark joined the Newstead lab in 2019 as a Clarendon Scholar undertaking his DPhil research on lysosomal membrane proteins. He obtained his B.Sc. and M.Sc. at the University of Wuerzberg, Germany, where he worked on Ubiquitin-Activating Enzyme Fragment-Based Screening. He also undertook a 4-month internship with John Kuriyan at UC Berkeley, researching Substrate Preferences along the Src-Family Kinases. Mark is co-supervised with Prof. Francis Barr. Mark is currently funded by an MRC Studentship.

Mr Simon Lichtinger: Wellcome Trust Chemistry in Cells DPhil student

Simon joined the group in 2021 as DPhil student studying the molecular basis for drug transport via SLC transporters. Simon is co-supervised with Prof. Phil Biggin and funded by the Wellcome Chemistry in Cells programme.

Kathryn joined the group in 2021 as DPhil student studying the role of potassium channels in health and disease and is jointly supervised with Professor Stephen Tucker in the Kavli Institute of Nanoscience Discovery.

Mr Sacha Salphati: BBSRC DTC DPhil student

Sacha joined the group in 2021 as a BBSRC-funded DPhil student (BBSRC DTC) studying the role of ion channels and transporters in lysosomal homeostasis and is jointly supervised by Professor Stephen Tucker in the Kavli Institute of Nanoscience Discovery. Prior to joining the lab, he obtained a BSc degree with a year in research in Biochemistry at Imperial College London. During this year of research, Sacha investigated the endocannabinoid system in zebrafish in the lab of Prof. Su Guo at UCSF.  He carried out his final year project with Dr. Doryen Bubeck and investigated protein complexes formed by pore-forming proteins.

Mr Sigurbjörn Markusson: Wellcome Cellular Structural Biology Student

Sigurbjörn is a Wellcome Trust-funded DPhil student in Cellular Structural Biology who joined the group in 2021 to study the structure and function of lysosomal ion channels, and their role in health and disease. Previously, he conducted a BSc study at the University of Iceland, focusing on elucidating the reaction mechanism of Vibrio alkaline phosphatase using X-ray crystallography, and an MSc degree at the University of Bergen, Norway, where he studied the structure of Arc and CNPase, using nanobodies as crystallisation chaperones.
