What we do

Research

We investigate how transcription factors regulate gene expression, how their competition with DNA repair leads to increased mutagenesis, and how gene regulation can be modulated using CRISPR-Cas systems.

We do this by integrating high-throughput experiments, quantitative biochemistry, genomic analysis, machine learning, and cell-based studies. We oftentimes use custom-designed cell-free systems and computational analyses/modeling to formulate mechanistic hypotheses, which we then test in eukaryotic cellular systems.

TANGO workflow for measuring dCas binding on a high-density DNA array

dCas proteins and epigenome editing

We develop highly sensitive high-throughput assays to decipher the DNA recognition properties of dCas9 and dCas12a, with the goal of improving the precision of genome and epigenome editing.

Mechanisms of transcription factor-mediated mutation enrichment across DNA sequences

Transcription factor-induced DNA mutagenesis

We investigate how transcription factors influence DNA mutagenesis at their binding sites by modulating DNA lesion formation and by directly competing with repair enzymes for the recognition of DNA lesions.

Comparison of predicted transcription factor binding variant effects across quantitative models

Quantitative regulatory genomics

We study how human transcription factors (TFs) find their genomic targets despite the complexity of the nuclear environment, and how sequence variation changes TF binding and gene regulation.
