Teaching interests
As a geophysicist I am interested in applying physical methods to look at plate tectonic and geodynamic processes. In addition, I use field studies to examine the evidence for oceanic crustal processes preserved in ophiolites. I have worked mainly in the eastern Mediterranean orogenic belt, but also have extensive experience of engagement with the International Ocean Discovery Program (that collects rock and sediment samples from the present-day ocean basins via scientific ocean drilling). I use my wide range of interests to inform my teaching. For example, I organise an annual nine-day field excursion to the Troodos ophiolite, Cyprus, drawing upon my research interests in this globally significant ophiolite.
Research interests
I use palaeomagnetic methods to investigate fundamental crustal processes.
A recent focus of my research has been the palaeomagnetic analysis of samples of lower oceanic crust recovered from the Atlantic and Pacific Oceans by the Integrated Ocean Drilling Program (and associated site surveys). In 2004/2005 I was a Shipboard Palaeomagnetist aboard the JOIDES Resolution on IODP Expedition 304/305. This recovered a complexly layered sequence of gabbros and minor ultramafic rocks from the footwall of a major oceanic core complex known as Atlantis Massif, located at 30 degrees north on the Mid Atlantic Ridge. The core, extending to over 1400 mbsf, opens a window in to lower crustal accretion processes. This was an exciting opportunity to extend my palaeomagnetic and magnetic fabric research in ancient ophiolitic terranes (which act as analogues for oceanic crust) into the modern ocean. Shorebased research was carried out in collaboration with Dr Chris MacLeod (Cardiff University), Dr Jeff Gee (Scripps Institution) and Dr Bobbie John (University of Wyoming). The award of a NERC Standard Research Grant allowed us to conduct detailed palaeomagnetic analyses of the Expedition 304/305 core materials, and to combine these with wireline log interpretation, geochronological and geochemical data to provide important insights into the spatial and temporal controls of the accretion of slow-spreading rate lower oceanic crust. The project benefited from the research of Dr Nicola Pressling, a NERC research fellow funded by the project.
In January-February 2008 I sailed on an IODP Site Survey cruise to the tectonic exposures of fast-spreading rate oceanic crust at Hess Deep, as part of a NERC funded cruise aboard the (then) new James Cook research vessel (cruise JC21). This provided essential site survey data (bathymetric swath-mapping and sampling using the NERC remotely operated vehicle ISIS) to support future IODP drilling at this key locality (IODP Proposal #551). My post cruise research has focused on a combined magnetic fabric and electron backscatter diffraction study of petrofabric development in lower oceanic crustal gabbros, in collaboration with Dr Chris MacLeod (Cardiff; Principal Scientific Officer on JC21), Dr Johan Lissenberg (Cardiff) and Dr Benoit Ildefonse (Montpellier).
In April-June 2011 I was Lead Shipboard Palaeomagnetist on IODP Expedition 335 to Hole1256D located in 15 Ma old East Pacific Rise crust formed at a superfast spreading rate. This was the fourth expedition to this hole, which is the only place in the world's oceans where drilling has penetrated a complete, in situ upper crustal sequence (lavas, sheeted dykes) and reached the underlying gabbros of the lower oceanic crust. My post cruise research will focus on palaeomagnetic and fabric analyses of gabbroic rocks and of dykes that have been contact metamorphosed to a granoblastic texture by heat from gabbro intrusions.
In April - June 2011, I was Lead Shipboard Palaeomagnetist on IODP Expedition 335, part of the "Superfast Spreading Crust" campaign focused on Hole 1256D. This deep hole was the first to reach the uppermost in situ gabbroic lower crust. Unfortunately, recovery during Exp 335 was limited due to challenging hole conditions, but samples have provided insights into the nature of the thermal boundary layer at the top of the lower crust.
In December 2012-February 2013 I was Lead Shipboard Palaeomagnetist on IODP Expedition 345 to Hess Deep in the Pacific Ocean. This recovered a suite of cores from primitive lower crustal layered gabbros for the first time, confirming the broad features of the ophiolite paradigm and providing a complete picture of the bulk geochemistry of fast-spreading EPR crust. Post cruise research is focusing on the development of magnetic fabrics in these layered gabbros and the origin of multicomponent remanences in these rocks.

Post cruise research is focusing on the development of magnetic fabrics in these layered gabbros and the origin of multicomponent remanences in these rocks.
In June-July 2014, I was back on board the JOIDES Resolution again, this time as Lead Shipboard Palaeomagnetist on IODP Expedition 351 "Izu-Bonin-Mariana Arc Origins", one of three back-to-back drilling expeditions designed to examine the evolution of the Izu-Bonin-Mariana arc system in the northwestern Pacific Ocean. This sampled a 1.4 km sedimentary succession documenting the responses of the upper plate to subduction initiation and the subsequent arc evolution. The site also penetrated into the "basaltic" basement, providing insights into the geochemistry and age of the basement rocks.
Most recently, in December 2015 - January 2016 I sailed as Lead Palaeomagnetist on IODP Expedition 360 "Indian Ridge Moho", that drilled into the footwall of the Atlantis Bank oceanic core complex on the SW Indian Ridge. This long-term project offers the prospect of drilling vertically through a geomagnetic reversal boundary in the oceanic crust for the first time, although we did not reach this level during Expedition 360 unfortunately.
In addition to research in oceanic tectonics via the IODP, I have also focused on the application of palaeomagnetic and magnetic fabric techniques to a range of geodynamic and tectonic problems within the Tethyan orogenic belt. Field areas have included central Greece, the Aegean Islands, Turkey, Cyprus, Syria and Oman. Examples include: (i) an integrated palaeomagnetic and structural analysis of the tectonic evolution of the Hatay ophiolite, southern Turkey (PhD research of Jennifer Inwood), and its relationship with the Baer-Bassit ophiolite (NW Syria) and Troodos ophiolite (Cyprus); (ii) palaeomagnetic analysis of the development of the arcuate Kyrenia Range terrane of northern Cyprus; (iii) the tectonic evolution of the Mersin ophiolite (Turkey), which exposes a superb sequence of lower oceanic crustal gabbros (PhD research of Mr Ahmed Omer); and (iv) magnetic fabric analyses of gabbros in the fast-spreading rate Oman ophiolite and their implication for lower crustal accretion (PhD research of Mr Matthew Meyer).
