My research seeks to understand the molecular basis of structural diversity, genetic organization, and mode of replication exhibited by animal mitochondrial DNAs. To this end, I am studying the mitochondrial genomes from several phylogenetically separated nematodes. My recent studies have focused upon mitochondrial DNA recombination, gene amplification and rearrangements in mermithid nematodes, obligate invertebrate parasites, and in the plant parasitic root knot nematode Meloidogyne. These mitochondrial DNAs appear to undergo "real-time" rearrangement, thereby generating a large array of polymorphic mitochondrial genome forms. We are evaluating the utility of these mitochondrial DNA types as useful markers to study population dynamics and cytoplasmic gene flow.

Dr.  Hyman participates in the Genetics, Genomics, and Bioinformatics Ph.D. Program and is a past Director. He also is a member of the Cell, Molecular, and Developmental Biology Graduate Program. He currently serves as the Faculty Director for UCR's CaTEACH-Science/Mathematics Initiative, designed to encourage mathematics and sciences students to pursue careers in teaching. He also participates and participates in IDEA, the UCR Institute for the Development of Educational Applications. He is a past Editor-in-Chief of the Journal of Nematology. Dr. Hyman is the Chair of UCR's Academy of Distinguished Teachers.
