My ongoing research interests are on moss floristics and basic bryophyte inventory activities. My field work shifted around 1997 from flowering plants to bryophytes with an emphasis in bryogeography through specimen acquisition to expand the diversity of the collections within the CAS herbarium. Thirteen plant species have been named in my honor including seven flowering plants and six mosses including the moss genus Shevockia endemic to Asia.

Evolutionary processes, Genomics, Phylogenetics, Hybridization
The Simison lab investigates the processes that generate, maintain, and reduce biodiversity. In particular, we are interested in the process of speciation. We use comparative genomics techniques such as RADseq, Ultra Conserved Elements, transcriptomics, and whole genomes to study the role of admixture and introgression in speciation. We are currently focusing on the globally invasive red eared slider turtle system (Trachemys scripta elegans) native to North America.
Research Scientist of Coleoptera
Phylogenomics, Curculionidae Systematics, Comparative Genomics
My research focuses on improving the tree of life for arthropods. Weevils (Curculionidae) are my focal taxon of choice. Weevils have specialized ecological habits, such as feeding on fungi, seeds, pollen, wood, roots and even kangaroo dung, weevils make an excellent system to study the evolution of different ecomorphologies. Currently I am focusing my efforts on whole genome sequencing and functional genomics in the genus Pachyrhynchus as well in the Cryptorhynchinae.
Curatorial Assistant II, Ornithology and Mammalogy
I am a biologist, graduated from the Pontificia Universidad Javeriana in Bogota, Colombia. I studied the density and distribution of the two toed sloth “Choloepus hoffmanni” in a Andean forest of Colombia as an undergraduate research thesis. In 2012, I graduated from San Francisco State University with a Masters degree in Biology, Conservation Biology. For my graduate thesis I studied the identification of an accurate technique to detect the OtHV-1 in California sea lions “Zalophus californianus”.

Deep-sea and coral reef octocorals - systematics and evolution
Research interests include the systematics and evolutionary biology of octocorals (soft corals, gorgonians, and pennatulaceans), which comprise 65% of all coral species diversity. Fieldwork is currently focused on two bathymetrically opposite regions of the world's oceans: coral reefs of the tropical western Pacific (the Philippines, Melanesia, and Micronesia), and the deep-sea benthos (particularly the west coast of North America and various deep ocean basins worldwide).
