I'm looking to hire a research technician/lab manager. This role is ideal for someone looking to gain experience and independence after undergraduate research on their way to graduate school. Please encourage anyone interested to apply: hr.myu.umn.edu/jobs/ext/374... (job code 374183)

Careers
The Fraser Lab at the University of Minnesota (https://fraserlab.psych.umn.edu/) is recruiting a full-time research technician to support the lab. As a part of the Department of Psychology we are involved in the greater neuroscience research community at the University of Minnesota which provides excellent access to training and professional development. The Fraser Lab is interested in the neurobiological basis of motivated behavior and investigates how defined brain circuits contribute to behavioral regulation. We make use of modern neuroscience approaches to record and manipulate neural activity in real-time as rodents perform complex behavioral tasks to relate precise aspects of neural activity to well-defined psychological processes. To do so, we regularly use optogenetics, chemogenetics, calcium imaging, biosensors, pharmacology, and immunohistochemistry. Our ultimate goal is to decipher the neural mechanisms regulating behavior and to characterize how these are altered in psychiatric illness, such as addiction, or by differences in lived experience, such as after early life adversity, to potentially identify novel therapeutics. We seek a team member who can play a lead role in lab operations, collaborate closely with the PI, and engage in team-building and growth.Duties:Laboratory logistics, maintenance and operations (30%):

The lesson for all the students out there is that science is a community project. Most of us make individually small contributions to this project. Success is measured at the collective level. Many of our professional (and personal) dysfunctions could be fixed by more fully embracing this view.
