We are in the Department of Biomedical Engineering and the McKusick-Nathans Department of Genetic Medicine at Johns Hopkins University. You can apply for graduate study in my lab through BME or the Ph.D. program in Human Genetics and Genomics.

Research Interests:

The ultimate goal of our research is to understand how gene regulatory information is encoded in genomic DNA sequence.

We have recently made significant progress using AI/ML to understand how DNA sequence specifies cell-type specific enhancer activity, target gene activation through looping constraints, and how dynamic enhancer-gene regulatory networks control cell-fate decisions and contribute to human disease. For details, see:

and other Publications.

Our work uses functional genomics DNase-seq, ATAC-seq, ChIP-seq, RNA-seq, CRISPR, MPRA, Hi-C, and chromatin state data to computationally identify combinations of transcription factor binding sites which operate to define the activity of cell-type specific enhancers and their activation of target genes. We are currently focused on:

  • improving AI/ML methods to build more accurate models of enhancer activity
  • predicting the impact of mutations on enhancer activity and their contributions to disease
  • using AI/ML models to build and test dynamic gene regulatory networks with targeted CRISPR perturbation
  • using large scale datasets (ENCODE/IGVF) and CRISPR to constrain models of enhancer-promoter interactions and DNA looping mechanisms
  • using this sequence based regulatory code to understand mechanisms of gene regulatory network disruption in cancer and develop therapeutic strategies

We are located in the McKusick-Nathans Institute of Genetic Medicine, and the Department of Biomedical Engineering, which has long been a leader in the development of rigorous quantitative modeling of biological systems, and is a natural home for graduate studies in Genomics, Bioinformatics, and Computational Biology at Johns Hopkins, including research in Systems Biology, AI, Machine Learning, and Dynamic Gene Regulatory Network Modeling.
