Tony Simon, Ph.D.Director
Dr. Simon is a pediatric cognitive neuroscientist. His research focuses on the interactions between neural, cognitive, affective and stress biology differences in young people with genetic disorders that produce learning difficulties, behavioral dysregulation and psychopathology. Dr. Simon has spent over a decade and a half investigating how dysfunction in specific neurocognitive processing systems, such as attention, and spatial or temporal processing generates cognitive impairments in thinking about space, time, numbers as was as real world challenges like math, using money and navigation. He has developed and is testing a digital neurotherapeutic intervention (in the form a video game) to minimize such disability.  Dr. Simon's current main project is a National Institute of Mental Health funded longitudinal study on risk and protective factors for psychosis proneness in chromosome 22q11.2 deletion (Velocardiofacial/DiGeorge) syndrome based on the interaction of neurocognitive and affective processing and stress reactivity.

Kathy Angkustsiri, M.D.Associate Professor of Pediatrics
Kathy received her B.A. in psychology with a minor in Human Biology from Stanford University.  She attended New York University for her medical training and completed a pediatric residency at Children's Hospital Oakland.  She joined the 22q Research Center and Clinic during her fellowship in Developmental-Behavioral Pediatrics and has been working with the team for over a decade. Her research interests include the parent-child relationship, optimizing functional and behavioral outcomes, and the interaction of physiological arousal with anxiety and adaptive behaviors.  Dr. Angkustsiri is medical director of the 22q Healthy Minds Clinic and also sees patients with 22q and other neurodevelopmental disorders in the MIND Institute's Massie Family Clinic.

Bryn Ritter, B.S.

Bryn Ritter, B.S.Junior Specialist
Bryn graduated with High Honors from the University of California, Davis with a Bachelor of Science in Neurobiology, Physiology, and Behavior and a minor in Chemistry. During her undergraduate, Bryn worked under Dr. Laura Tully investigating neural mechanisms related to cognitive control of emotion in individuals with psychosis using neurostimulation (tDCS) and neuroimaging (fMRI) techniques. Additionally, Bryn completed her Honors Thesis on the contribution of biological sex and social sensitivity to comorbid psychosis and cannabis use disorder. Bryn currently works with Dr. Simon on psychosis proneness, conducting clinical interviews to assess for attenuated psychotic symptoms.

Kathley LeTran, B.S.

Kathley LeTran, B.S.Junior Specialist
Kathley graduated with Highest Honors from the University of California, Davis with a Bachelor of Science in Psychology with an emphasis in Biology. During her undergraduate, Kathley worked under Dr. Tamara Swaab exploring neural mechanisms related to language comprehension in young and older adults through EEG and behavioral testing. Along with working at the Cognitive Neuroscience of Language Lab, she was a research assistant under Dr. Tony Simon in investigating the risk and protective factors for psychosis proneness in chromosome 22q11.2 deletion syndrome. Additionally, Kathley completed her Honors thesis on introducing a Support Vector Machine decoding method as an analytical tool for EEG data in a word prediction paradigm. Kathley continues to work with Dr. Simon on psychosis proneness, collecting EEG/ERP data and administering cognitive assessments.

Samantha Linton, Ph.D.

Samantha Linton, Ph.D.Postdoctoral Researcher
Samantha graduated from the University of Sheffield with a Bachelor of Science in Psychology in 2013, followed by a Master of Science in Psychological Research Methods in 2015, and a PhD in Psychology and Cognitive Neuroscience in 2018. Samantha specializes in the use of psychophysiology, most commonly EEG/ERP techniques, to study emotion processing in developmental populations, with a particular interest in how anxiety may influence how adolescents process emotional cues in their environment. She is currently working with Dr. Simon on his longitudinal study on risk and protective factors for psychosis proneness in chromosome 22q11.2 deletion (Velocardiofacial/DiGeorge) syndrome.
