Biography

William came to New Zealand in 2012 after beginning his career in the United States, where he earned his Masters Degree in Genetic Epidemiology and then worked as a Programmer Analyst at the McDonnell Genome Institute at Washington University in St. Louis. In New Zealand, William completed his PhD at the University of Auckland (Liggins Institute, under the leadership of Wayne Cutfield and Justin O’Sullivan), where he was focused on the functional consequences of the three-dimensional structure of genome organization.

Research | Current

My areas of expertise involve the analysis of deep sequence data: genome mapping, variant detection, RNA-sequencing, methylome epigenetics, and metagenomics data.

 

In addition to my research, I also have joined a bioinformatics group with the goals of developing of a universal nationwide New Zealand bioinformatics teaching toolset. My current teaching role has centered around developing, delivering, and promoting a consistent bioinformatics infrastructure for the New Zealand research community.

 

My research focus is on the intersection of genetic and epigenetic research with modern “big data” approaches to answers. In this quest, William is actively seeking out answers in the analysis of high-throughput genetics (next generation sequencing) and the impact that common variations in genetic sequence have on the three-dimensional structure of the genome within the nucleus.

 

Hypothesis: Amongst 3 billion bases of DNA lurks some 10 million points of genetic variation, making us who we are as individuals. In some cases, those variants contribute to diseases. Around two-thirds of those disease-associated variants are in non-coding regions of the DNA, a major challenge to those hoping to attribute these variants to altered function. Ultimately, this makes it difficult for scientists to understand why this variation is hazardous to our health, leaving diagnosis tricky and remediation nearly impossible. Some of these non-coding genetic changes can alter structural relationships within the nucleus, altering regulatory patterns, resulting in disease risk in humans. Thus, the failure of GWAS to turn SNP associations into clinically-relevant (actionable) causes for disease has resulted from a genetic approach that tries to link the complex phenotype to only the local genetic landscape. My approach aims to describe how non-coding regions of the DNA alter 3D organization of DNA in the nucleus, resulting in altered function.


For example, applying structural genomics to the problem of post-term birth. Somewhere between 5-20% of all births are post-term (born after 293 days – 41 weeks – of gestation), an affliction that carries both short- and long-term health consequences for the child. We identified genetic influences on birth timing and related these changes to alterations in enhancer regions, altering the three-dimensional structure of the genome within the nucleus. From this, we identified several major pathways for possible pathogenesis, most notably haematopoiesis. The next steps here are to understand how genetic variation in this pathway can directly influence gestational timing, hopefully in a way to improve obstectric management of birth as well as to identify ways to mitigate the later-in-life health effects related to prolonged gestation.

 

Work at the institute has led to several successful collaborations within the UK, USA, and Finland.

Areas of expertise

William’s areas of expertise involve genome mapping, variant detection, RNA-sequencing, epigenetics, and analysing of environmental metagenomics data. Outside of his research, William’s teaching role at the University has centered around developing, delivering, and promoting a consistent bioinformatics infrastructure for the New Zealand research community.
