Synaptic Neurophysiology, Plasticity, Learning and Memory
We are interested in understanding mechanisms and functional implications of plasticity in small neural networks in the context of learning and memory. Our toolbox includes transgenic/knockout mouse models, slice electrophysiology, optophysiology, calcium imaging, molecular biology techniques and animal behavior assays.
We are looking for creative, highly motivated graduate students and postdoctoral fellows to join our group. Talented undergraduate students with a strong science background are also welcomed. Interested candidates should email Diasynou directly (email@example.com).
For postdoctoral fellows in particular, we are looking for scientists with a PhD in neuroscience or a related field with background in any of the following: protein biochemistry (protein phosphorylation), electrophysiology, advanced imaging techniques or rodent behavior. Applicants should have demonstrated productivity. International applicants proficient in oral and written English are welcome to apply.
The fellows will benefit from a dynamic and highly collaborative environment in the Center for Neuroscience as well as opportunities to interact with the extended scientific community at UC Davis, which ranks among the top 10 public research universities in the US. They will also enjoy the lifestyle of northern California. These are full-time positions, with salary commensurate to NIH scale and health benefits. Interested candidate postdocs should e-mail a CV and a brief cover letter with contact information for two references. UC Davis is an equal opportunity/affirmative action employer.
