PlasmidHawk

Plasmidhawk pipeline

Background

We developed PlasmidHawk, a linear time pan-genome alignment-based pipeline to predict the lab-of-origin of unknown sequences. Compared to the previous deep learning method, PlasmidHawk has higher prediction accuracy. PlasmidHawk can successfully predict unknown sequences’ depositing labs 76% of the time and 85% of the time the correct lab is in the top 10 candidates. In addition, PlasmidHawk can precisely single out the signature sub-sequences that are responsible for the lab-of-origin detection. PlasmidHawk represents an explainable and accurate tool for lab-of-origin prediction of synthetic plasmid sequences

NLM Postdoctoral Fellow

Leo (NLM Postdoctoral Fellow, primary mentor Prof. Lauren Stadler, secondary mentor Prof. Todd Treangen) received his PhD in Computer Science at Rice University in 2019 working on statistical modeling of DNA sequence evolution. He was advised by Dr. Luay Nakhleh, the J.S. Abercrombie Professor and Chair of the Department of Computer Science at Rice. Since joining at Rice, Leo was awarded a graduate research fellowship from the National Library of Medicine, has published work in computational biology in journals such as Bioinformatics, presented research at scientific conferences like RECOMB-CG in Barcelona and WABI in Helsinki, and contributed to a soon to be released book on computational modeling of evolutionary histories of genomes.

PhD student

Bryce (1st year PhD student) received his MS in Bioinformatics and BS in Computer Science + Chemistry from the University of Illinois at Urbana-Champaign. As an undergraduate, he worked at Dow Agrosciences in both the computational biology and cheminformatics groups. His projects included developing software for phylogeny analysis and creating models for compound activity prediction. During his Master’s program, Bryce worked in a biochemistry lab developing software for genome mining as well as a on research project for creating bit-wise algorithms for the C++ STL. One of his main interests is casting biological and chemical problems into theoretical computer science questions.
