Our Team

Marta Soden, PhD, Principal Investigator

Marta received her B.A. from Mount Holyoke College, where she majored in Neuroscience and Behavior. She went on to receive her PhD in the laboratory of Dr. Lu Chen at UC Berkeley, studying local translation and homeostatic synaptic plasticity in the hippocampus. Marta then completed a postdoctoral fellowship with Dr. Larry Zweifel at the University of Washington, where she began studying dopaminergic circuits and neuronal excitability. She was thrilled to be able to stay at UW as faculty in the Pharmacology department and start her own research group.

Siyi Ma, PhD, postdoc

Siyi joined the Soden lab as a postdoctoral fellow after completing her PhD at McMaster University where she studied the development of synaptic inputs in the rodent brainstem. Currently, she is interested in examining the structure and function of neurotransmitter/neuropeptide co-transmitting inputs in the VTA using electrophysiological and electron microscopy techniques. Outside the lab, Siyi enjoys doing needlework and experimenting with new recipes in the kitchen.

Mary Loveless, graduate student

Mary joined the Soden lab as a research technician in 2022, where she became fascinated by neuropeptide/fast transmitter corelease dynamics and their role in motivated behavior. In 2024, Mary entered the UW Graduate Program in Neuroscience as a Ph.D. student and, after completion of her first year, enthusiastically returned to the Soden lab as a graduate student comentored with Dr. Michael Bruchas. Outside of lab, you can find Mary hiking, baking sweet treats, and hanging out with her dogs.

Dustin Sumarli, research technician

Dustin graduated from UW with a B.S in Psychology and ACMS in 2024, where he became interested in brain-computer interfaces (BCIs) and data-driven neuroscience. He joined the Soden lab to be closer to the benchwork and learn more about being a researcher before pursuing graduate school. In his free time, Dustin enjoys playing instruments and video games.

Grace Davis, research technician

Grace joined the Soden lab in the summer of 2024 after moving cross-country from the East Coast. She earned her Bachelors of Science in Neuroscience from the University of Vermont, where she became fascinated with how the nervous system motivates feeding behavior. In addition to research, Grace is passionate about teaching and increasing accessibility in STEM. In her free time, Grace enjoys reading, cooking, and competing in triathlons.
