Rachel Marcus
Neurochemistry and Cognition Lab, 3rd Year
Elizabeth Marsh
CoPE Lab, 3rd Year
Liam McMahon
Howard Lab 3rd Year
Quynh Nguyen
Quynh Nguyen
CoPE Lab, 4th Year

Broadly, Quynh is interested in executive functions, reward processing, and psychopathology. She has previously studied the neural circuitry of reward loss in rodents and the socio-emotional development of children with Autism Spectrum Disorder. Her current research in the CoPE Lab examines how stress and executive function deficits, among other factors, can confer risks for psychopathology. Outside the lab, Quynh can be found doing yoga, trying new recipes, and drinking lots of coffee.

Ryan O'Leary
Memory and Cognition Lab, 3rd Year
Jourdan Parent
Jourdan Parent
Neurochemistry & Cognition Lab, 5th Year

Jourdan is a Ph.D. student in the Neurochemistry and Cognition Lab. She graduated from Boston University with a B.A. in Neuroscience. Her research projects use MR and PET imaging techniques to understand how individual differences in catecholamine function are related to higher-level cognition and brain network activity in healthy older adults. Currently, she is working on several projects focused on assessing how local and long-range functional connectivity is associated with changes in catecholamine synthesis capacity, Alzheimer’s Disease pathology, and cognitive function in aging.

Hannah Park
Hannah Park
Ashton Graybiel Spatial Orientation Laboratory, 5th Year

Hannah is a PhD student in the Ashton Graybiel Spatial Orientation Laboratory. Her interests are the age-related cognitive differences in postural balancing and interplays between associative learning and sustained attention. Currently, her focus is on the differentiation and application of the strategies on postural control in a balancing task (balancing an inverted pendulum with a joystick).

Xiaolin Qiao
Xiaolin Qiao
Howard Lab, 4th Year

Xiaolin Qiao is a PhD student in the Howard Lab studying the effect of mental imagery on learning and decision making. She is also interested in the underlying neural mechanism of these processes.

Diane Rohrer
Diane Rohrer
Knight Lab, 5th Year

Diane is a Ph.D. student in Dr. Raymond Knight's lab. Her area of study lies at the intersection of sexual aggression and psychopathology. As a Masters student at Brandeis her thesis explored the latent factor structure underlying a commonly utilized static risk assessment tool. For her doctoral work she is interested in studying how disgust sensitivity and pain tolerance manifest in sexual and non-sexual sadism. In her spare time she enjoys rock climbing and traveling with her husband, brewing beer, and snuggling her Shih Tzu, Reign of Terror.

Luke Sim
Luke Sim
Ashton Graybiel Spatial Orientation Laboratory

Luke is PhD student currently with the Ashton Graybiel Spatial Orientation Lab. Previously investigating
subjective extrapolation of human movement variability during a cyclic reaching task at Cleveland state
University, he now seeks to understand how people learn to model and predict the gravitational
trajectory of objects. His expertise focuses on quantifying motor performance to assess the motor
adaptation process and understanding how we as humans utilize internal models to guide our
predictions of motion.
