I have oversight of the Biomedical Degree Programme which incorporates BSc degrees in Biomedical Sciences, Neurosciences, Pharmacology and Physiological Sciences. I contribute to a range of undergraduate modules within degrees spanning all years but have a specialist focus in areas related to molecular physiology, development, respiration and exercise. Beyond the School of Life Sciences, I contribute early years teaching to the MBChB and BDS programmes and assist with taught postgraduate programmes offered by the School of Medicine.
Modules I contribute teaching to:
BS11002 Introduction to the Life Sciences: why go multicellular?
BS11003 Laboratory and Research Skills 1A
BS12002 Life: the underlying structures
BS22001 Biomedical Sciences
BS22003 Laboratory and Research Skills 2C
BS31016 Practical Techniques in Biomedical Sciences [Module Manager]
BS32020 Human Epithelial Biology [Module Manager]
BS32022 Human Morphogenesis and Embryonic Development
BS41005/6 Research Skills in Biological Sciences
BS41006 Advanced Biomedical Topics/Research Communication Skills [Module Manager]
BS41007 Research Project: Biomedical Sciences [Module Manager]
BS42015 Oxygen Uptake & Utilisation [Module Manager]
DS10001 Pre- and Para-clinical Dentistry 1
MS10000 MBCHB Year 1
I started out in laboratories in the UK (Aberdeen), Canada (UBC, Vancouver) and the US (MBL, Woods Hole) that subscribed to a concept known as the “August Krogh Principle” which states that many processes contributing to human disease can be studied using organisms with naturally evolved defences to extreme conditions. For example, we studied how fish tolerate the very low oxygen levels in the Amazon River through to freeze tolerance and hibernation in freshwater frogs and turtles. This work was (and still is) relevant to several areas of medicine such as the action of anaesthetics, the preservation of organs for transplant, understanding why organs fail during heart-attack or stroke, how fuel use is regulated during periods of feast and famine and how cancerous tumours grow despite little access to nutrients or oxygen.
Many of the same processes that enable survival of harsh conditions, perhaps surprisingly, also influence organ development in pregnancy. I study how these processes influence the precisely balanced branch-like growth of the respiratory tree and promote the formation of lung defects in diseases such as Tuberous Sclerosis, Birt-Hogg-Dubé syndrome and Cystic Fibrosis.
