They graduated from UCR in 2020 with their BS in psychology and completed an honors project that examined intersectionality and identity development among Deaf students attending a school for the Deaf ( Their research interests include identity studies among racial/ethnic minority Deaf and hard of hearing individuals and etiologies of depressive and trauma-related psychopathologies using developmental and relational perspectives.

Amanda Sadri

Amanda Sadri is a second-year graduate student in the Psychology Ph.D. program developmental area at UC Riverside. She completed her BA in psychology at UC Riverside and later studied in the Post-Baccalaureate program in Psychological Science at UC Irvine. In 2019-2021, she coordinated a clinical study at UC Berkeley. Prior to coming full circle and pursuing her doctoral training at UCR, Amanda’s program of research examined the development, expression, and reduction of violence and delinquency in varied settings (e.g., schools, families, forensic hospitals, neighborhoods) among juvenile justice and mental health system-involved children and families.

At UCR, Amanda is concerned with behavioral and cultural processes of risk and resilience among youth with markedly disrupted and disadvantaged backgrounds. She studies how the forms (e.g., physical, relational) and functions (e.g., proactive, reactive) of aggression map onto individual (e.g., physiological markers, mental representations) and contextual (e.g., parenting, neighborhood crime rates, cultural expectations) factors. Her work refines culturally responsive theory and practice aimed at mitigating aggressive and carceral outcomes for high-risk youth and encourages a greater appreciation for the ways in which children’s behavior varies in meaning and adaptive significance across diverse contexts.

In her free time, Amanda likes to run long distances, cook for her family and friends, and drink hot tea.


Amanda Sadri es una estudiante en el segundo año del programa de doctorado en Psicología del Desarrollo en UC Riverside. Completó su licenciatura en psicología en UC Riverside y luego estudió en el programa de posgrado en ciencias psicológicas en UC Irvine. En 2019-2021, coordinó un estudio clínico en UC Berkeley. Antes de cerrar el círculo y continuar con su formación doctoral en la UCR, el programa de investigación de Amanda examinaba el desarrollo, la expresión y la reducción de la delincuencia y la violencia en diversos entornos (por ejemplo, escuelas, familias, hospitales forenses, vecindarios) entre la justicia juvenil y la salud mental de niños y familias involucrados en el sistema.

En UCR, Amanda estudia los procesos culturales y de comportamiento de riesgo y resiliencia entre jóvenes con antecedentes marcadamente perturbados y desfavorecidos. Ella se interesa cómo las formas (p. ej., física, relacional) y las funciones (p. ej., proactiva, reactiva) de la agresión se asignan al individuo (p. ej., marcadores fisiológicos, representaciones mentales) y contextual (p. ej., crianza de los hijos, tasas de delincuencia en el vecindario, expectativas culturales) factores. Su trabajo refina la teoría y la práctica culturalmente receptivas destinadas a mitigar los resultados agresivos y carcelarios para los jóvenes de alto riesgo y fomenta una mayor apreciación de las formas en que el comportamiento de los niños varía en significado y significado adaptativo en diversos contextos.

En su tiempo libre, a Amanda le gusta correr largas distancias, cocinar para su familia y amigos y beber té caliente.

AnnaMaria Boullion

AnnaMaria Boullion is a third-year graduate student in the Developmental Psychology program at UC Riverside. AnnaMaria transferred from Shasta Community College with an A.A. in Behavioral Science to California State University, Chico, where she completed both her BA and MA degrees in Psychological Science. As a graduate student at CSU Chico, AnnaMaria developed an interest in early adversity, protective factors, and resilience. Her research projects focused on childhood maltreatment, growth mindsets, and psychological resilience.

AnnaMaria is committed to identifying and understanding modifiable processes, such as emotion regulation and meaning-making, that contribute to individual differences in how youth navigate adverse life events. AnnaMaria enjoys art, trying new things, and exploring new places in her spare time.

Jessie Bridgewater

Jessie Bridgewater is a fifth-year graduate student in the Developmental Psychology program at UC Riverside. She completed her BA in psychology and MA in clinical psychology at California State University Northridge (CSUN).  As a graduate student at CSUN, she was the lab manager for Dr. Jonathan Martinez’s Promoting the USE of Evidence-based practices: Narrowing the Treatment Engagement gap (P.U.E.N.T.E.) lab. In this work, she focused on increasing Latino/a parental engagement in children’s mental health services. Her thesis focused on the relationship between adverse childhood experiences (ACEs) and various domains of adaptive functioning both across racial/ethnic groups (i.e. Hispanic/Non-Hispanic) and maltreated experience (i.e., those who experienced childhood maltreatment vs. those who did not).

Guided by the tenets of developmental psychopathology, Jessie’s emerging program of research asks the following question: What accounts for individual differences in youth’s responses to childhood adversity with a particular emphasis on structural contributors to adversity (e.g., poverty, carceral and child welfare systems, and ethnic and racial discrimination)?

Jessie’s favorites: Spicy/pickled foods, hiking, reading, and anything pertaining to cats.

Erick Perez

Erick Perez is a fourth-year graduate student in the Developmental Psychology program at UC Riverside. He completed his BA in Psychology from California State University Northridge. While there, he was a National Institute of Health BUILD PODER Scholar working on research that addressed the motor and social barriers to physical activity and fitness among young adults with Autism Spectrum Disorder. His research at UC Riverside focuses on improving the assessment and treatment of Fetal Alcohol Spectrum Disorder. Additionally, Erick is interested in how individuals cope with the loss of their loved ones. He seeks to understand how bereavement and grief vary across cultures, the lifespan, and the context surrounding the loss (e.g., cause, timing, relationship to the deceased). While at UCR, Erick has been working with Dr. Misaki Natsuaki in the Developmental Transitions lab and is now excitedly also joining the Ad Lab.

Erick likes: Wu-Tang, treflips, stage dives, high fives.
