3D Shape Analysis of Typical and Atypical Neuro-Facial Growth and Development
My main research focus is in craniofacial dysmorphism and the development of mathematical techniques and software tools for 3D dense surface model (DSM) analysis (Hammond, 2007). We have analysed 3D facial photographs to delineate facial dysmorphism in individuals with genetic conditions such as Noonan, Smith-Magenis, Williams and 22q11 del syndromes (Hammond et al, 2004 & 2005), Cornelia de Lange syndrome (Bhuiyan et al, 2006), and Wolf-Hirschhorn syndrome (Hammond et al, 2012; Hannes et al, 2012).
DSM techniques have been applied to several image modalities to study affected children and associated animal models to identify:
the role of GT2FIRD1 in craniofacial dysmorphism in Williams syndrome (Tassabehji et al, 2005) using 3D photographs and 3D micro-CT images
the role of neural crest migration in craniofacial dysmorphism in Bardet–Biedl syndrome (Tobin et al, 2008) using 3D facial photos and 3D laser scans
novel craniofacial differences in Fragile X syndrome (Heulens et al, 2012) using 3D facial photos and 3D micro-CT images
The Fragile X syndrome study also involved novel signature graph techniques recently developed (Hammond and Suttie, 2012) while I was on a sabbatical at the Wetherall Institute of Molecular Medicine in Oxford kindly hosted by Professor Andrew Wilkie. These new techniques were developed specifically to address the paucity of subjects available for studies of rare genetic disorders. Provided sufficient healthy subjects are available to normalize facial form, individual and small numbers of children with extremely rare conditions, such as Fibrodysplasia Ossificance Progressiva (Hammond et al, 2012), can be analyzed.
A recently published application of the signature graph techniques was in a mouse model of fetal alcohol syndrome where 3D MRI images were used to show that face-brain effects vary in relation to timing of ethanol exposure (Lipinski et al, 2012). A study of fetal alcohol spectrum disorder in children describes how pediatricians might use the software tools we have developed to visualize atypical face shape. We have also demonstrated links between facial dysmorphism and neurocognitive performance in fetal alcohol syndrome (Suttie et al, 2012).
morph between mean faces of controls and children diagnosed with fetal alcohol syndrome
More recent work on face-brain-behaviour effects began with autism spectrum disorders (Hammond et al, 2007) and has continued more recently with 22q11 deletion syndrome (Sindeberry et al, 2012). A further broadening of face-brain applications, in conjunction with Professor Sanjay Sisodiya of UCL’s Institute of Neurology, has used atypical face shape in epilepsy to identify co-morbidity (Kasperavičiūtė et al, 2011; Novy et al, 2012)and genomic structural variants (Chinthapalli et al, 2012).
These techniques and their application are being developed further in a part-time PhD programme by research assistant Mike Suttie.
Computational models of cell behaviour
A second more recent thread to my research is mathematical and computational models of cell-cell and cell-collagen interactions. The former arose from collaborations with oral biologists interested in understanding oral cancer (Maheswaran et al, 2007). The latter is a collaboration with Professor Paul Riley (formerly UCL and now Oxford Univ) in co-supervising a PhD student, Abbygail Shaw, who is building a model of scar formation in the heart following myocardial infarction.
