I was born and spent my early childhood in Cape Elizabeth ME. For the rest of my childhood and adolescence, I lived in Rochester NY and attended Brighton Public Schools. In 2006 I began my undergraduate studies at the State University of New York at Brockport, where I dual majored in psychology and philosophy. In the Department of Psychology, I owe thanks to Dr. Lori-Ann Forzona, who is an excellent instructor of research methods. In the Department of Philosophy, I benefited greatly from the guidance and friendships of Dr. Gordon Barnes and Dr. Georges Dicker. For my senior year, I studied abroad at the University of Oxford, focusing tutorials on personality psychology, philosophy of mind, and the history of modern philosophy. After obtaining my B.S. in 2010, I began work as a research assistant at the Mt. Hope Family Center. As a research assistant, I worked on a study investigating the impact of parental conflict and at-risk environments on preschool children’s coping and adjustment. At the Mt. Hope Family Center, I owe thanks to Dr. Patrick Davies and Dr. Melissa Sturge-Apple. In 2013 I began a Ph.D. at the University of Texas at Austin under the guidance of Dr. Elliot Tucker-Drob and Dr. K. Paige Harden. During my doctoral training, I developed expertise in applied statistics and became a core member of the Texas Twin Project. To date, my research has addressed a number of factors that contribute to mental health and well-being, including personality risk for antisocial behavior, particularly sensation seeking and callous-unemotional traits. More recently, I developed a path model using multiple polygenic scores to test and control for pleiotropy in Mendelian randomization studies. I've also been exploring whether different personality traits are associated with differential gene expression related to immune system functioning, searching for social-relational correlates of psychological well-being using genetically-informative designs, and modeling longitudinal patterns of psychiatric comorbidity in childhood and adolescence. Finally, I work part-time as a statistical consultant for the Minnesota Center for Chemical and Mental Health. In sum, I try my best to avoid intellectual and empirical pigeonholes by pursuing an interdisciplinary program of research that addresses a broad range of questions related to health and well-being.
