- Modern human craniofacial variation and identification
- Geometric morphometric analysis of the head and face
- Police witness composite images
- Face depiction and recognisability
Facial Approximation of Aunty (2011)
Unidentified remains, Belanglo State Forest (2010)
As an applied researcher in evidence-based facial approximation (sometimes referred to as facial reconstruction) I work with the skeletal remains of modern humans to approximate their facial appearance. Although I started in the forensic application of facial approximation, my research focus has been predominantly within an archaeological context, including the Lapita people excavated from Vanuatu (3000BP), early Maori from New Zealand (600BP) and an individual of the Huarpe people in Argentina (500BP). Through CAS I am, amongst other projects, exploring the applicability of these techniques to archaic hominins, such as Homo floresiensis (95000-17000BP). More recent work (with regards to time since death) has included medico-pathological individuals on display at the Royal College of Surgeons, Edinburgh (100BP) and in collaboration with Sydney Homicide, unidentified remains found in Belanglo State Forest, New South Wales (2-10BP).

My research interests that relate to the skills and understandings involved in a facial approximation include how adult people’s faces and their features vary, how facial shapes are related to recognisability and identification, what changes to the face due to various states such as emotion, sleep, injury and death, and how the techniques of depiction (including police witness composites, photography and portraiture) affect how a face is both represented and understood.
Facial landmarks and geometric morphometrics to identify individual facial variation (2009 - present)
In a facial approximation facial muscles serve primarily to ‘flesh out the face’, many representations have expressive functions which are related to our evolutionary survival. Interestingly, most images of archaic hominins and some representations of modern humans from our pre-history are intentionally extremely expressive. Understanding how to manufacture these emotional displays relates to the morphology of the skull, and of course, individual differences in these structures.

I am currently finalising three research papers in the areas of forensic facial approximation (with NSW Police), the impact of head pose on facial shapes (continuing on from a research project with the Victoria Police), and the effect of memory on familiar faces (with WA Police). Planned projects include:
· Establishing an orthogonal frontal/lateral photographic database of adult human facial variation
· Examining the existing body of facial approximations of LB1 (The Hobbit), and the use of modern techniques with non-moderns, working with the Liang Bua team
· Continuing to develop hands-on, intensive laboratories building up the facial anatomy used within a facial approximation over a replica skull (2D and 3D) for various groups of participants across diverse disciplines and fields. To date these have included: artists, anatomists, anthropologists, animators, archaeologists, biologists, dentists, forensic artists and scientists, primary, secondary and tertiary teachers and students, and members of the general public
· Continuing to engage in popular science, including delivering public talks in the area of facial approximation
