Computational analysis of genomic and clinical data to aid medical decision making.

In the new "post-genome" era of personalized medicine, many variants critical to disease susceptibilities, prognosis and drug sensitivities will be identified and increased numbers of people will undergo DNA sequencing. We are developing algorithms and tools intended to facilitate this process.


  • Ph.D student Collin Tokheim's work on cancer driver prediction featured in the Baltimore Sun.
  • Assistant Research Professor David Masica is applying his MOCA algorithm to classify cysts that may be precursors to pancreatic cancer. Read about how Dave's mathematical model is being used in Science Daily.

About the Karchin Lab

We develop computational models to interpret and predict the impact of individual variation in the genome, transcriptome, and proteome. The models are being applied to cancer genomics, unclassified variants in Mendelian disease genes, and complex disease genetics. In collaboration with clinicians, pathologists, and experimental biologists, we aim to make significant improvements in individualized medicine within the next five years.
