Ph.D. Candidate in Neuroscience, Iowa State University

My name is Brittany Larsen. I am currently a third-year Doctor of Philosophy student studying neuroscience with prior educational background in health promotion sciences, addiction science, and dietetics. My core research interests include the investigation of underlying neurobiological mechanisms of Alzheimer's disease as well as the influences of adiposity and metabolic dysfunction on the structure and function of the brain and Alzheimer's disease risk. I have previously worked as a Clinical Dietitian in a critical access hospital for approximately 2.5 years, during which time I first became aware of the prevailing myriad gaps in knowledge within the nutrition field. This revelation ignited my aspiration to become a scientist. Consequently, I resigned from my position to attend graduate school in 2016, initially enrolling in a Doctor of Philosophy program in health promotion sciences.

During this time, however, my primary passion began to shift from nutrition to neuroscience, which was especially amplified after I took my first behavioral neuroscience course. The complexity of the field in combination with the prevailing, surprisingly marginal understanding of the brain drove my ambition to acquire the skill set necessary to conduct research and aid in the expansion of the neuroscience knowledgebase. I, therefore, opted to graduate from the health promotion sciences program with a Master of Science degree and instead enroll in a Doctor of Philosophy program in neuroscience in 2019. In spite of my nutrition-based educational background and work experience, my current neuroscience program has enabled me to incorporate my previously acquired skill set into my current research. My career path has led me to reside in multiple different states across the country. My most recent move was from Connecticut to start the doctoral program in Iowa. Outside of the research world, some of my favorite personal hobbies include traveling and extreme sports.
