Garrett joined Elliot Tucker-Drob\u2019s lifespan development lab as a clinical psychology PhD student in 2022 after graduating from Sonoma State University as a McNair Scholar with a BA in psychology and a minor in applied statistics. While at Sonoma State, he collaborated with Dr. Adam Zagelbaum to develop a trauma curriculum for incarcerated men which was focused on socioemotional education to help individuals to promote healing from their past trauma, develop resilience against the ongoing trauma of incarceration and aid in community reintegration upon release. Additionally, through the Leadership Alliance Early Identification Program, he had the opportunity to spend the summer at Vanderbilt University under the supervision of Dr. Kathryn Humphreys, investigating the mechanisms behind the intergenerational transmission of psychopathology, which began an interest in the influence of genes on the development of mental health disorders. Broadly, Garrett is interested in how negative life experiences can lead to the development of psychopathologies or dysfunctional behaviors, as well as alternative conceptualizations of mental health disorders which aim to move past the disease model of psychopathology to better appreciate the continuous nature of symptom severity in clinical populations. His current research aims to illuminate the intersection of personality and psychopathology through the use of molecular genetic methodologies to explore the relationship between normal range variation in human traits and variation in symptom presentation and severity in mental health disorders.<\/p>\n\n\n\n
