Micaela S. Parker

I am a research scientist and coordinator for the Pacific Northwest Center for Human Health and Ocean Studies. I use molecular techniques to understand the biochemistry of cellular processes in marine phytoplankton. For my Ph.D. thesis research, I investigated the expression of genes involved in the cycling of carbon and nitrogen within a diatom cell during photorespiration using two diatom species (Thalassiosira weissflogii and Thalassiosira pseudonana). For my work with the Center for Human Health and Ocean Studies, I am using comparative genomics and expression libraries to understand the genes that are differentially expressed in Pseudo-nitzschia australis and Pseudo-nitzschia multiseries cells when they produce the toxin domoic acid. The goal is to uncover genes involved in toxin production and develop these as markers for assessing toxin production in field samples. I also collaborate with other members in our lab on various projects, including the discovery of ferritin in Pseudo-nitzschia species (for more information on this project, see Adrian Marchetti's webpage). For more information on the Center for Human Health and Ocean Studies, please see our website. For more information on my previous research projects, please see my CV.
