Profile

Claudia Cabrera received her bachelor’s degree in engineering in Information Systems from the Universidad Regiomontana in Mexico and a PhD in Bioinformatics tools for the dissection of complex traits from The Roslin Intitute, University of Edinburgh. After the bachelor’s degree she did some teaching in computer science and then pursued an MSc in Bioinformatics at the University of Leicester. She undertook a career development fellowship at the Human Genetics Unit of the Medical Research Council in Edinburgh, where she and colleagues developed a software and the methodology for the analysis of gene-set enrichment in genome-wide association studies. Claudia joined the William Harvey Institute in 2012 as a Postdoctoral Fellow and forms part of the Centre for Translational Bioinformatics led by Dr. Michael Barnes.

Research

Research Interests:

Development and application of bioinformatics tools and methodologies for a better understanding of complex traits and diseases. Areas of research include genetical genomics data analysis of hypertension and cardiovascular diseases, response to trauma (injury), and paediatric endocrinology among others.

Analysis and annotation of high-throughput data :

  • Whole genome sequencing
  • Exome sequencing
  • RNA-Seq
  • Genome-wide association studies
  • Microarray analysis

Software development: genomicper (CRAN)

https://CRAN.R-project.org/package=genomicper

Circular genomic permutation approach uses GWAS results to establish the significance of pathway/gene-set associations whilst accounting for genomic structure. All SNPs in the GWAS are placed in a 'circular genome' according to their location. Then the complete set of SNP association p-values are permuted by rotation with respect to the SNPs' genomic locations. Two testing frameworks are available: permutations at the gene level, and permutations at the SNP level. The permutation at the gene level uses fisher's combination test to calculate a single gene p-value, followed by the hypergeometric test. The SNP count methodology maps each SNP to pathways/gene-sets and calculates the proportion of SNPs for the real and the permutated datasets above a pre-defined threshold. Genomicper requires a matrix of GWAS association p-values. The SNPs annotation and pathways annotations can be performed within the package or provided by the user.
