Algorithm for Detecting Repeated Genomic Regions
https://patents.google.com/patent/US20190214110A1/A patent for the method has been filed (see the link mentioned above).
Detection of Insufficient Homology Regions in a Reference Sequence
https://patents.google.com/patent/US10545792B2/I designed an algorithm for using a Merkle tree-like data structure to track the provenance of a workflow's intermediate files and final results. The memoization algorithm allows interrupting workflows to be rapidly restarted. Furthermore, uniquely identifying object hashes allow intermediate and final data files to be stored platform-wide, allowing redundant computational steps to be avoided in a completely transparent fashion.
