Richard Wilton received his MD at UCLA, where he subsequently became an associate professor in general pediatrics with both clinical and research responsibilities.  His work involved software development for patient data tracking in clinical settings and for social services case management.

Dr. Wilton joined Alex Szalay's computing research group at Johns Hopkins in 2008.  He collaborated in the initial design and software implementation of the data archive for the PanSTARRS survey telescope.  More recently, his research has focused on performance optimization of algorithms for biological sequence alignment, on efficient archival and retrieval of DNA short read data, and on optimal integration of sequence alignment tools in genomic data analysis pipelines.
