My research area focuses on gene expression covariances in single cells. For this, I identify sets of genes that covary strongly in their expression, and then I apply an unbiased screening approach to reveal which main regulator causes the covariances for the given set.
Today, sequencing of DNA from ancient samples is a standard method in Paleogenomics, however, RNA is generally unstable due to the ubiquitous presence of RNases in the environment.
