Research Statement

My general research interest lies in developing computational approaches for analysis of high-throughput data to help uncover novel biology. More specifically, there are three major directions my lab focuses on. 

1. Pathway analysis: we maintain and improve the FGSEA package (https://bioconductor.org/packages/fgsea) for pathway analysis, with recent developments targeted towards working with single-cell and spatial data.
2. Network analysis: our lab works on a set of network analysis approaches with a focus on applications in the immunometabolism field (https://artyomovlab.wustl.edu/shiny/gatom/). 
3. Public data mining: we facilitate access to public transcriptomics data with gene expression analysis web-tools like Phantasus (https://artyomovlab.wustl.edu/phantasus/).
