Shriya Sethuraman, PhD

Computational biologist and bioinformatics scientist. Ten years in genomics, four of them in industry across clinical diagnostics and cell-therapy discovery, on a foundation of epigenomics and noncoding RNA.

My work spans microbial and pathogen genomics, transcriptomics, epigenomics, immunology and cell therapy, and the statistical modeling that ties them together. In practice that has meant building the curated reference database and analytical validation behind a regulated clinical sequencing test for bloodstream infection, including the specificity work that decides whether an organism can be distinguished from its near neighbors; redesigning a 64-gene T-cell engineering screen and its low-input readout when the original design could not be traced back to its conditions; mining public single-cell and bulk transcriptomic atlases to nominate therapeutic targets in autoimmune disease; and building probabilistic models that separate real signal from noise in sparse, repetitive sequencing data.

The thread running through all of it is the same: deciding what the data actually supports, and being able to defend where the line was drawn.

Repositories

  • classification-qc — quality checks that flag when taxonomic classification output should not be trusted: host DNA surviving depletion, reference-database gaps, implausible taxa, contamination spikes
  • PolV_Surveillance — four-class hidden Markov model classifying every position in a genome as real transcript, residual signal, noise, or a previously unrecognized low-signal class (PNAS 2020, co-first author)
  • nucleosome_methylation — establishing the causal direction between DNA methylation and nucleosome positioning, rather than the correlation alone (bioRxiv, co-first author)
  • PolV_transcript_calling — identifying noncoding transcripts from immunoprecipitation sequencing data
  • Xchr_inactivation_mouse — allele-specific analysis of imprinted X-chromosome inactivation in mouse (Genome Biology 2017)
