I am a second year M.S. student in Dr. Elise Granek's Lab at Portland State University. For my masters thesis, I am assessing the effects of fluoxetine (i.e. Prozac) on the California mussel, Mytilus Californianus, to determine if environmentally relevant concentrations are affecting mussel physiology and their susceptibility to predation. I am interested in the ecological connections between terrestrial and marine ecosystems. Much of my research focus is in community and applied ecology. I plan to continue his academic endeavors as a PhD student in the Fall of 2015

Beyond Erin Brockovich

Last month I lost my friend and colleague at DEQ, Sonja Bjorn-Hansen to a tragic suicide. I know, not a chipper way to start a blog post but I thought I’d share a bit about her here to honor her memory and the terrific accomplishments she personally made towards protecting Oregon’s environment. Sonja worked in […]

As a Oregon Sea Grant Natural Resource Policy Fellow, I work with the Oregon Department of Environmental Quality to help develop their storm water monitoring program. The folks at ODEQ develop monitoring and management plans of pollutants that enter Oregon’s aquatic, atmospheric, and terrestrial environments. I have been working with the water quality permitting section of ODEQ, which sounds pretty technical […]

Prozac project changes

Posted by: | June 16, 2015 | No Comment |

When I last checked in, I had just begun a pilot study that would assess how shell thickness in mussels may be affected by exposure to Prozac. Unfortunately, the experiment was a bust, mostly owing to the impractical housing conditions which stressed the animals and led to high mortality. I quickly scrapped this project, with […]

On my last post, I mentioned that we were breaking down the 90-day experiment, where we exposed mussels to environmentally relevant levels (0, 0.3, 3.0, 30.0, and 300 ng/L) of fluoxetine. We had measured mussel length and width as well as mass and water clearance rates, so see if fluoxetine had an effect on mussel […]

December 18 marked the end of a 90-day exposure study. During this time, we exposed the mussel Mytilus Californianus to regular doses of the drug, Fluoxetine which is the active ingredient in Prozac, a selective serotonin reuptake inhibitor (SSRI) antidepressant. For this project, we wanted to determine if environmentally relevant levels of fluoxetine affect the mussels’ […]
