My research interests involve exploring the multifaceted protective and promoting factors across various systems within at-risk populations. Specifically, I focus on individuals who engage in nonsuicidal self-injury (NSSI) or experience mental health challenges. Additionally, I am dedicated to the development of impactful interventions that facilitate positive adaptation among these individuals.

​Meng Han,Ph.D.

Post-doc Fellow

I specialize in research on mental health help-seeking, psychological intervention for adolescents and young adults, and the development of gender identity. My interests lie in understanding the factors that influence individuals' decisions to seek help for their mental well-being, exploring effective interventions to enhance psychological health among young populations, and studying the complexities of gender identity development and its impact on mental health.


Zhijun Wu, Ph.D.

Post-doc Fellow

I am a researcher with a keen interest in adolescent mental health, particularly in understanding the mechanisms underlying non-suicidal self-injury (NSSI) and suicide. My work also focuses on identifying the protective and risk factors associated with NSSI. I am particularly drawn to large-scale longitudinal studies as they offer valuable insights into the long-term trajectories of mental health outcomes. My research aims to contribute to the development of effective interventions and policies to support adolescents' mental well-being.


Mei Yu, Ph.D.

Post-Doctoral Fellow

My research interests revolve around the domains of delay discounting, cognitive control, reward, and development. Specifically, I am intrigued by studying how individuals make decisions involving delayed rewards and examining the underlying cognitive processes involved. Additionally, I am interested in exploring how reward processing and cognitive control mechanisms develop across the lifespan. Through my research, I aim to gain insights into the factors that influence decision-making, enhance our understanding of cognitive development, and contribute to the development of interventions promoting optimal decision-making and cognitive functioning.


Yajing Sun, M.D.

Post-Doctoral Fellow

My research interests focus on pediatric psychiatry. I am passionate about studying mental health disorders and their impact on children and adolescents. I aim to explore various aspects of pediatric psychiatry, including diagnostic criteria, treatment modalities, and early intervention strategies. Through my research, I aspire to contribute to the field by improving our understanding of mental health issues in young populations and developing effective interventions to support their well-being.


Juan Wang, Ph.D.

Post-Doctoral Fellow

My research interests encompass adolescent mental health, with a specific focus on understanding the transition and protective factors associated with self-harm and suicide. I am dedicated to investigating the complex interplay between individual characteristics, environmental factors, and social networks in shaping adolescent well-being. By examining peer social networks, I aim to uncover the influential role they play in mental health outcomes and explore potential interventions that promote positive peer relationships and resilience among adolescents. Through my research, I strive to contribute to the development of effective strategies for supporting adolescent mental health and preventing self-harm and suicide.


Huagen Wang, Ph.D.

Post-Doctoral Fellow

My research interests focus on investigating the risk factors associated with high-risk populations, including psychiatric patients exhibiting non-suicidal self-injury behaviors and adolescents with mood disorders. Additionally, I am intrigued by exploring the intricate relationship between pain and non-suicidal self-injury behaviors, while delving into the underlying neural mechanisms. Through my research, I aim to contribute to the understanding of these complex phenomena and potentially develop interventions that can effectively support individuals in these populations.
