Lara Foland-Ross, PhD

Senior Research Scholar

Dr. Lara Foland-Ross is a Research Scholar at the Center for Interdisciplinary Brain Sciences Research. Dr. Foland-Ross received her PhD in Neuroscience from the University of California, Los Angeles in 2010, and was a Postdoctoral Fellow in the Stanford Neurodevelopment, Affect, and Psychopathology Laboratory from 2010-2015 through the support of an NIMH F32 Grant and a NARSAD Young Investigator Grant. Dr. Foland-Ross' work focuses on brain and behavioral development in children and adolescents using a multi-method approach (neuroimaging, behavioral paradigms, genes and hormones). She is particularly interested in the effects of pubertal hormones on brain circuits underlying mood and executive function, and how hormone-based changes in these circuits may influence everyday behaviors in the developing teen.

At Stanford, she hopes to expand her passion in creating a warm environment within her team and in clinical settings while expanding her knowledge on neuropsychological testing.  Her current interests revolve around the relationship of hormones and behavior, adolescent development, and trauma-related anxiety disorders. 

Tracy Jordon, PhD

Postdoctoral Scholar

Dr. Tracy Jordan is a licensed Clinical Psychologist at Stanford Children's Health, Lucile Packard Children's Hospital Stanford and a research scholar at the Center for Interdisciplinary Brain Sciences Research. Dr. Jordan received her PhD in Clinical Psychology with an emphasis in Pediatric Neuropsychology from Palo Alto University. She completed her pre-doctoral internship in Pediatric Psychology and Neuropsychology at the University of Minnesota Medical School/Masonic Children's Hospital and her post-doctoral fellowship in Clinical Neuropsychology at Stanford University. For her graduate dissertation research project, she investigated X-chromosome dosage effects on visuospatial skills in pre-puberal girls with Turner Syndrome. Dr. Jordan's previous work has also focused on neurodevelopment and treatment outcomes in children with Hurler Syndrome (MPS Type 1). Currently, Dr. Jordan is particularly interested in genetic and hormonal influences on neuropsychological functioning (learning, memory, visuospatial skills, executive functioning, and social cognition) in children and adolescents.  

Matthew Marzelli, MS

Research Data Analyst

Matthew Marzelli is a Research Data Analyst at the Center for Interdisciplinary Brain Sciences Research. He received his M.S. in Bioengineering from Stanford University and was an NSF Graduate Research Fellow in the Department of Radiology. His past research focused on the development of novel brain imaging methods using ultra high-field (7 Tesla) magnetic resonance imaging (MRI). His current research interests include the development of robust image acquisition and processing tools for both MRI and near-infrared spectroscopy (NIRS) as a means to better investigate links between brain structure, function, cognition, and behavior.

Graduate Student Researchers

Jen (she/her) is a doctoral candidate researcher and a doctoral student in Clinical Psychology at the PGSP-Stanford PsyD Consortium. She received her B.S. cum laude in Psychology with a minor in International Studies: Comparative Religion from the University of Washington in 2016, where she was a Mary Gates Research Scholar. After graduation, Jen explored the healthcare field by working in a number of different roles, such as a Pediatric Mental Health Specialist on a children’s inpatient psychiatric and behavioral medicine unit and as a Medical Scribe for emergency department physicians. Prior to matriculating into the PGSP-Stanford PsyD Consortium in 2019, Jen was working as a Data Analyst in the Philip R. Lee Institute for Health Policy Studies within UCSF’s School of Medicine, assisting on studies related to wellness and smoking cessation in residential substance use disorder treatment settings.
