Filbey Lab Team

Francesca M. Filbey, Ph.D.
Principal Investigator

Dr. Filbey is the Bert Moore Endowed Chair and Professor at the School of Behavioral and Brain Sciences at the University of Texas at Dallas.  Her studies focus on determining the neurobiological mechanisms of reward system dysfunction.


Erin D. Horne, Ph.D. Postdoctoral Research Associate

Erin received her Ph.D. in Cognition and Neuroscience from UT Dallas in 2019. Her doctoral research focused on identifying the neural correlates of episodic memory retrieval associated with healthy aging and on investigating how increasing attentional demands during a retrieval task modulates brain activity (measured with fMRI). Currently, she is investigating how addiction affects the structure and function of the brain and is particularly interested in the relationship between cannabis use, sleep, and memory consolidation.

Jennifer DiMuzio
​Research Assistant

Jenn is a currently a research assistant working as Team Lead  on the “Multisite Study of Cannabis Users and Non-Users” project. She has over 8 years of neuroimaging research experience working with diverse populations, including adolescents and young adults with bipolar disorder, ADHD, and marijuana dependence and abuse, adult Veterans with PTSD, depression, and suicidal ideation, young adults diagnosed with schizophrenia, and student athletes vulnerable to concussion. She has also previously worked as a research assistant on the ABCD Study at the University of Utah site. Her research focus is on adolescent cognitive development, specifically how environmental factors, including onset of substance use and early life stress/trauma, are associated with neurobiological and behavioral changes.

Christina Atkinson, M.S.
​Research Assistant

Tina received her M.S. in Cognition and Neuroscience from UTD in May 2019. She is currently working as the Team Lead on the Cognition and Cannabis Use study. Previously she interned in the NeuroPsychometric Lab at UTD by assisting with fMRI scans and running behavioral tasks for the Multiple Sclerosis study and coordinating communication in a double-blind study on mindfulness. Her interests include investigating the neural mechanisms behind addiction and discovering ways to assist individuals with disorders.

Mackenzie Taylor
Ph.D. Student

​Mackenzie Taylor is a Ph.D. student in the cognition and neuroscience program at UT Dallas working in the Filbey lab. She received her bachelor of science in Psychology and minor in Biology at Texas Wesleyan University in May of 2017. Previously she has worked in research focus areas such as behavioral neuroscience, self-control and impulsivity, and pharmacology. She has also worked closely with addiction through previous clinical work. Currently, she is interested in biomarkers of the brain and body, behavioral markers, and genetic markers that are indicative of changes related to the addiction process.

Dalton Edwards
Ph.D. Student

Dalton is a Ph.D. student in the cognition and neuroscience program at UT Dallas working in the Filbey lab. He received a bachelor of arts in psychology with a minor in sociology from Texas State University in May 2018. He also received a master of arts in psychological research from Texas State University in May 2020. Previously his work has focused on electrophysiology with a focus on how executive brain functions like attention are influenced by environmental changes. Currently, he is interested in investing how substance use may influence sleep architecture and other mental processes.
