This lead her to work in the pharmacology lab at U of M during her undergrad, where she studied the oxidation and recycling of potassium channels in the myocardium in the context of oxidative stressors. She then joined the MSU MD/PhD program, and completed her PhD in Pharmacology & Toxicology. For her dissertation, she studied sex diffrences in the physicology of neural circuts in mouse models of depression. She discovered a difference between male and female mice in the activity of the neural projection from the hippocampus to the nucleus accumben, a circut that has been linked to addiction and depression. Liz showed the heightened activity of this circuit in female mice, and this activity may be linked to an exaggerated susceptibility to mood disorders such as depression. She is interested in continuing her research throughout her medical career.
