Title: Bridging Worlds: Community-Grounded Implementation Science for the Future of Global Mental Health

Job Talk Zoom Link   

Speaker Bio: Diana C. Parra Pérez, PT, MPH, PhD, is a public health researcher, implementation scientist, certified yoga & mindfulness facilitator, and vibrational sound practitioner whose work bridges rigorous science, health equity, and community-grounded practice. For two decades, she has generated and translated evidence on community-based health interventions across Latin America and among underrepresented communities in the United States, with research contributing to the nationwide scale-up of community health programming in Brazil and informing WHO and UN-Habitat policy. 

Her research program spans community-based mental health and mindfulness for underrepresented populations, implementation science in low- and middle-income countries, and transdisciplinary coalition building. She is Co-Principal Investigator on an NIH/NIA-funded study of a culturally adapted mindfulness program for Latinx older adults at risk for Alzheimer's disease, and Co-PI on an NSF ADVANCE grant advancing faculty equity through civic mindfulness. 

A twice-recognized Clarivate Highly Cited Researcher, she founded a university-wide transdisciplinary mindfulness initiative and has led community coalitions advancing health equity through a CDC REACH cooperative agreement. Bilingual and bicultural, her work is guided by cultural humility, contemplative practice, and a deep commitment to building bridges across disciplines, communities, and borders in service of mental health for all.

Title: Building the Future of Global Mental Health: Community Partnerships, Implementation Science, Technology, and Determinants of Mental Health Equity

Job Talk Zoom Link   

Speaker Bio: Samantha (Sam) C. Winter, PhD, is an Associate Professor at the Columbia University School of Social Work and Founder and Co-Director of the Anga Center for Community Health and Well-being in East Africa. Her research examines how climate change, environmental conditions, violence, and other social determinants shape mental health and well-being, with a particular focus on informal settlements in East Africa. Through long-standing community partnerships in Kenya, Uganda, and Tanzania, Dr. Winter develops and evaluates community-centered interventions that strengthen mental health and improve health equity. Dr. Winter's work integrates community-based participatory research, implementation science, digital health, climate science, and emerging technology to develop scalable solutions for global mental health. She currently leads or co-leads multiple NIH-funded studies, including the NIH-funded Anga Center, which advances transdisciplinary research and capacity strengthening at the intersection of climate justice, health equity, and community well-being. She is also the founder and co-lead of the Sauti Mashinani Research Lab, an interdisciplinary research and mentoring community that supports the next generation of global health scholars. Her work seeks to reimagine global mental health by integrating community partnership, environmental justice, technological innovation, and implementation science to build more equitable and resilient health systems.

Speaker Bio: Ashley Hagaman, PhD, MPH is an Associate Professor in the Department of Social and Behavioral Sciences at the Yale School of Public Health, where she serves as Director of the Global Health Concentration. She also holds a secondary appointment in Yale’s Department of Anthropology. Dr. Hagaman is a medical anthropologist and qualitative methodologist whose research focuses on suicide prevention, global mental health, and strengthening mental health systems through community-anchored and systems-embedded research. Her scholarship advances culturally grounded qualitative methods, including innovations that center local epistemologies in implementation research. She leads NIH-funded clinical trials in Nepal, Pakistan, and the United States focused on improving access to quality mental health care through community and health system partnerships. She is deeply committed to building the next generation of global mental health researchers, with a particular focus on supporting women scholars through long-term international research partnerships. Ultimately, her research seeks to generate evidence that transforms how health systems deliver equitable, culturally responsive mental health care, improving outcomes for populations disproportionately affected by suicide and mental health disparities.
