Roger was awarded his PhD in 2004 from the University of York (UK), where he investigated the metabolic activity of porcine embryos in vitro with Professor Henry Leese. During this time, he worked with Sygen International, Berkeley, Ca, with Dr Lali Abeydera.
He then undertook a fresh challenge, studying the origin of DNA damage in oesophageal cancer and its pre-cancerous lesion, Barrett’s Oesophagus, in the lab of Dr Laura Hardie at the University of Leeds (UK). He combined the methods from this period of doctoral training with his prime interest of reproductive physiology to discover links between metabolic activity and DNA damage in the preimplantation embryo, during a second post-doctoral position at the University of York.
On the strength of this, he was awarded a Wellcome Trust VIP fellowship, and funding from the Medical Research Council, which lead to his current position. He joined HYMS in Jan 2010 as a Lecturer of Reproductive Medicine and was made Senior Lecturer in July 2014. He was made Chair of the HYMS Post Graduate Programmes Board and Post Graduate Board of Examiners in Jan 2016.
The lab combines the use of model organisms, clinical samples and human embryonic stem cells to investigate the effects of metabolic activity on fertility and long-term metabolic health of offspring. Current research themes include:
- Regulation of early embryo metabolism
- Molecular level
- Interindividual variation
- Non-invasive assays of embryo viability
- Stem Cell Metabolism
- Metabolic requirements of differentiation
- Metabolic requirements of reprogramming
- Effect of environment
- Impact of in vitro environment on embryo viability
- The effects of the in vitro environment on human embryonic stem cells
- Modelling the in vivo reproductive environment
- Maternal metabolic status and fertility
- Intergenerational effects of metabolic syndrome and related pathologies
- Platelet metabolism
- Biochemical regulation of energy provision during platelet function
The lab uses a wide variety of techniques to address these questions, including
- Nanofluorometric assays
- Seahorse bioenergetics
- High Performance Liquid Chromatography
- Liquid Chromatography-Mass Spectrometry
- Protein assays
- Advanced Imaging techniques
- Single-cell measurements of DNA damage
