PhD Student in Bioinformatics

Development of methods for cancer detection from cell-free DNA in blood samples:

When cells die, fragments of their DNA may enter the blood stream. This DNA is extracted from blood plasma and whole-genome sequenced. General differences in fragment distributions of healthy and sick subjects are used to detect cancer.

R Package Development

Development of open source R packages such as groupdata2, cvms, rearrr and xpectr.

Have written multiple tutorials and book chapters. What good are tools if no one can use them?
