Heather B. Weiss is founder and director of the Harvard Family Research Project (HFRP; www.hfrp.org) and senior research associate/instructor at the Harvard Graduate School of Education. Founded in 1983, HFRP's mission is to improve practice, intervention, and policy to support children's successful development from birth to adulthood. Dr. Weiss and her HFRP colleagues conduct, synthesize, and disseminate research and evaluation information and develop professional and organizational learning tools that support evaluation, continuous improvement, and accountability and that spark innovation. A cornerstone of HFRP's work is the promotion, documentation, and assessment of complementary learning: strategies that support children's learning and development in family and community settings as well as school contexts. Under Dr. Weiss's leadership, HFRP created the national Family Involvement Network of Educators (FINE); informed policy development in the areas of children, youth and families; and significantly expanded its complementary learning resources to include early childhood education, afterschool and expanded learning time opportunities, and digital media and learning. Dr. Weiss writes, speaks, and advises on programs and policies for children and families and is a consultant and advisor to numerous foundations on strategic grant making and evaluation. Her recent publications focus on reframing research and evaluation to support continuous improvement and results-based decision making, examining the case for complementary learning from a research and policy perspective, and assessing new ways of providing and evaluating professional development. Dr. Weiss received her EdD in education and social policy from Harvard University. Holly Kreider is program officer in family engagement at the Heising-Simons Foundation in Los Altos, California. Dr. Kreider leads family engagement grant making for the Foundation, including direct service grants in local counties, as well as state- and national-level research, evaluation, and policy grants. Previously, Dr. Kreider served as director of programs for Raising A Reader National Office, overseeing training, evaluation, and affiliate relations with 165 agencies across the United States. She also previously served as vice president at Sociometrics, leading federally funded and private sector research and evaluation projects focused on children's mental health, adolescent pregnancy prevention, HIV/STI prevention, and family strengthening. Finally, Dr. Kreider was a research associate at the Harvard Family Research Project (HFRP) and an instructor at the Harvard Graduate School of Education for more than a decade. At HFRP, she managed research projects and developed best practice resources in areas of family engagement, out-of-school time, teacher professional development, and program evaluation. At HFRP, she also cofounded the Family Involvement Network of Educators-a national network of more than 12,000 educators and other professionals committed to engaging families in their children's education. She is author/editor of four books and dozens of publications, including Promising Practices for Family Engagement in Out-of-School Time (IAP, 2011) and Promising Practices for Engaging Families in Literacy (IAP, 2013). Dr. Kreider received her EdD in human development and psychology from Harvard University. M. Elena Lopez is associate director at the Harvard Family Research Project. Her research interests focus on the relationships of families, schools, and communities in children's development and education. She has co-led evaluations of public and philanthropic initiatives to promote children's well-being, created tools to facilitate family engagement for high school success and college and career readiness, and provided technical assistance to states and communities in order support quality programs for young children and families. As a cofounder of the Family Involvement Network of Educators, a national network of more than 12,000 preK-12 educators, Dr. Lopez seeks to facilitate the usability of research in practice, policy, and professional development. Her other professional experiences include lecturing at the Harvard Graduate School of Education, working as a program officer for a philanthropic foundation, and serving on national advisory and governing boards.
