Research InterestsResearch Interests
I study the evolutionary genomics of Myxozoa, a bizarre assemblage of microscopic, oligocellular, obligate endoparasites of poikilothermic vertebrates such as fish and frogs as well as vermiform invertebrates such as oligochaetes. Despite their parasitic life strategy and extreme morphological degeneracy, myxozoans have been confirmed by recent studies to be highly reduced cnidarians, putatively sister to Medusozoa (e.g., jellyfish, hydras, box jellies). Using newly generated transcriptomic data from several myxozoan species, I am exploring in a comparative framework the genetic transition to parasitism of this lineage, the functional genetics of cnidarian features such as polar capsules (homologous to cnidae) and metazoan features such as cellular communication, and the phylogenetic position of Myxozoa within Cnidaria.
My research also focuses on computational biological pipelining. Using Python, R, and SQL databasing, I have written several bioinformatic workflows for the handling and interpretation of genomic data, including a software package for phylogenetic analysis and functional annotation of gene family content across a set of user-specified genomes.
