The important role nutrition has in the neurological and neurobehavioral health of individuals led me into the field of nutritional metabolic research. As a graduate student within Emory's Nutrition and Health Sciences program, I had the opportunity to complete an interdisciplinary study combining the knowledge of genetics, nutrition, and neuroscience to better understand the challenges and treatments common to Phenylketonuria (PKU), an inherited amino acid metabolism disorder. My dissertation focused on a cohort of PKU subjects as they begin taking sapropterin (BH4), a pharmaceutical form of the tetrahydrobiopterin cofactor essential for phenylalanine hydroxylase function. My investigation involved measuring peripheral neurotransmitters in PKU patients both on and off sapropterin during one year of follow-up. I also investigated QOL in the same patient cohort.

As a current postdoc at Emory Genetics, I am assisting with an investigation into sapropterin’s effects on markers of oxidative stress and cardiovascular function as well as further analysis of markers in nutrition status in PKU patients who have and have not responded to sapropterin with improved Phe levels.

Currently I am seeking follow up postdoctoral opportunities that will provide me with more laboratory neuroscience and biochemistry experience while continuing to foster my interest in how nutrition modifies neurological aspects of patient health and wellbeing.
