I am a Senior Lecturer in Epigenetic Epidemiology at the University of Bristol, UK.

Epigenetics is the study of mechanisms that determine biological charactistics independently of DNA sequence. Epigenetic mechanisms have critical roles in development and response to the environment.

Epidemiology is the study of health and disease in populations.

I create R packages and scripts for analysing DNA methylation datasets generated using the Illumina Infinium Beadchips, but have also created scripts for analysing data generated using other types of microarrays and high-througput sequencing.

• The EWAS catalog is an online database of summary statistics of published epigenome-wide association studies.
• meffil is for the quality assessment, normalization and analysis of genome-wide DNA methylation datasets.
• ewaff is for testing associations in genome-wide DNA methylation datasets.
• dmrff is for identifying differentially methylated regions.
• meffonym is for calculating scores for a long list of DNA methylation models for estimating things like age and smoking history.
• alspac is for querying the ALSPAC study data which is stored in SPSS and STATA formats.

I regularly produce an update of the Epigenetic Epidemiology literature 1-2 times per month.

I aim to write code that is as beautiful as perishky is tasty.
