His scholarly writing addresses early childhood care and education programs, school readiness, and developmental assessment of young children. Gilliam has led national analyses of state-funded PreKindergarten policies and mandates, how PreKindergarten programs are being implemented across the range of policy contexts, and the effectiveness of these programs at improving school readiness and educational achievement, as well as experimental and quasi-experimental studies on methods to improve early education quality. His work frequently has been covered in major national and international news outlets for print (e.g., New York Times, Wall Street Journal, USA Today, Chicago Tribune, LA Times), radio (e.g., NPR), and television (e.g., CNN Headline News, NBC TODAY Show, CBS Early Show, ABC Good Morning America, ABC World News Tonight, FOX News).

Ms. Klotz (she/her/hers) is currently a doctoral student in Human Development and Family Studies, with a concentration in Child Development, at Michigan State University. Ms. Klotz’s program of research focuses on how to reduce risk and bolster resilience by identifying and promoting protective factors for children and families facing adversity. She is interested in understanding how early experiences of maltreatment affect relationships with a resilience-based lens of promoting healthy development in young children, including by reducing stress and supporting the psychosocial wellbeing of caregivers. Given the importance of relationships for children’s development, she is interested in further understanding what aspects of relationships (or relational quality) might buffer experiences of trauma, and the intergenerational effects thereof.
