Research Experiences
GWAS: plink, eQTLs, epistasis (BMC Genomics, 2015), gene expression,
synergy, genotype imputation, population stratification, recombination
Population Genetics: genetic ancestry, ancestry prediction, visualisation of
population data (AncestryMapper – PLoS One, 2012)
Data Integration: integrating novel and public data – SNPs, CNVs, epigenetic
modifications, DNA-protein interactions from ENCODE, NIH Roadmap,
Chromosome Capture Experiments, etc.
Pharmacology: combinatorial modeling of the effects of multiple drugs on
platelet activation (PloS Computational Biology, 2015)
Structural Biology: antibodies, tessellation, prediction of biophysical
properties, machine learning
Interests:
• Statistical & Population Genetics, Complex Traits, Epigenetics,
Next-Gen Technologies, Molecular Evolution
The Skills:
• Managing ‘Big Data’: data organising, cleaning, formatting
and general ‘wrangling’ – (Python, mySQL, Shell Scripting)
• Analysis (BIG & small data): hypothesis tests, statistical
modeling, supervised/unsupervised learning, data
visualisation – (R, Bioconductor, ggplot2, Cytoscape)
Current Projects:
• PhD Leftovers: GPCR gene expression in Alzheimer’s,
Recombination in Autism
• ChIP-chip analysis of yeast epigenetic modifications
• Developing tool to visualise comparisons amongst many
publicly available ChIP-Seq data sets
Teaching/Workshops
• Teaching experience: R & statistics to 1st year PhD students,
Introduction to Bioinformatics to undergraduates
Planned Workshops
• Python programming and R statistical computing workshops
for PhD students, Post-Docs and PIs in August/September
– How to work computationally with your data (Bye bye Excel!).
– How to explore, analyse and visualise your data.
