Elida Laski
Associate Professor of Developmental Psychology
Lynch School of Education, Applied Developmental & Educational Psychology, Boston University

Prior to earning her Ph.D. under the supervision of Dr. Robert Siegler, Dr. Laski received a Masters degree in Early Childhood Education and worked in public schools for over 5 years, first as a kindergarten teacher, then as a Reading Recovery teacher, and later as a literacy coach for the Boston Public Schools providing professional development to teachers of children in preschool through lower elementary school.

Dr. Laski's research focuses on understanding how cognitive processes are involved in mathematics development during early childhood. A second line of work explores the extent to which psychological learning principles are present in teacher education and classroom practice. She has published in psychological and educational journals and has presented in work at numerous international conferences. In 2011, Dr. Laski was nominated for a prestigious James T. McDonnell Scholar Award. In 2015, she was awarded the Early Career Outstanding Paper Award by the Developmental Psychology Division of the American Psychological Society.

Patrick Lemaire
Professor of Psychology
Aix-en-Provence University

After receiving his Ph.D. in Psychology from the University of Bourgogne, Dijon, in 1993, Dr. Lemaire worked as a postdoctoral fellow in cognitive development with Bob Siegler at CMU. In 1995, he was hired as a Research Associate at the CNRS. He spent 1998 as an invited Professor at Princeton University, and in 1999, was hired as Full Professor of Developmental Psychology at the University of Provence (Aix-Marseille University) where he has been ever since. In 2001, Dr. Lemaire was nominated as a Junior Member of Institut Universitaire de France (IUF) for 5 years. In 2011, he was nominated as a Senior Member of IUF for 5 years.

Dr. Lemaire teaches developmental psychology, focusing on children’s development and cognitive aging. He investigates both general and specific issues regarding lifespan cognitive development, for example, how children’s and adults’ thinking changes with age, how the type of strategies used to accomplish cognitive tasks change, and how strategy selection and execution change with age. He also examines mechanisms of cognitive changes for both children and adults, and how older adults compensate for age-related decreases in processing resources.

Xiaodong Lin-Siegler
Professor of Psychology
Teachers College, Columbia University

Dr. Xiaodong Lin-Siegler studies ways to increase students' motivation to learn, particularly in science, technology, engineering, and mathematics (STEM) related classes. She designs and studies the impact of different learning environments, instructional activities, and new media on students' motivation to learn and solve challenging problems. A theme that runs throughout Dr. Lin-Siegler's research is the uses of biographical information or “people knowledge” to change students' beliefs about achievement and to help them understand their own feelings about hard work and frustration encountered in school (metacognition). This places her work at the intersection of motivation, metacognition, technology, and science education. She finds that making explicit the struggles scientists experienced prior to success enhances students' ability to deal with challenging STEM learning tasks. However, optimum learning from these stories requires students to feel emotionally connected to the scientists and to recognize their own talents and potential to succeed through effort. This work was published in the Journal of Educational Psychology in April, 2016. Since then, over 25 news media publicized her work, including CBS News, PBS Kids, Science, Atlantic Quartz, BBC News, News India, China Peoples Daily, etc.

Dr. Lin-Siegler's work has earned her several awards, including being selected as a Carnegie Scholar by the Carnegie Corporation of New York and receiving the American Educational Research Association (AERA) Early Career and Outstanding Research award. She was named the Yellow River Scholar by the Chinese government in 2016 and served on the expert advisory board of the Organization of Economic Cooperation and Development (OECD) for the EDUCATION 2030 Initiative from 2015-2020.

Hugo Lortie-Forgues
Lecturer in Education, University of York, UK

Hugo Lortie-Forgues completed a Ph.D. in developmental psychology from the Université du Québec à Montréal (2007-2013) and a postdoctoral fellowship at Carnegie Mellon University (2013-2015). Hugo's research focuses primarily on the development of mathematical understanding, in particular how children and adults learn arithmetic involving fractions and decimals. These topics are crucial for later mathematics achievement and for the ability to succeed in many occupations. Unfortunately, fraction and decimal arithmetic pose substantial difficulties for many children and adults; a situation that has shown little sign of improvement over the past three decades. Given how important proper comprehension of fraction and decimal arithmetic is, a major goal of his research is to understand how children and adults process this type of learning in order to develop resources that will help them learn maths better.

Michael Schneider
Professor of Educational Psychology, University of Trier, Germany

Michael Schneider investigates the role of knowledge acquisition processes in competence development. Among his research interests are relations between mental magnitude representations and broader mathematical competence, conceptual and procedural knowledge in science and mathematics learning, and the effects of teaching methods on competence development.

After completing his Ph.D. at the Max Planck Institute for Human Development in 2006, he was a postdoc in Robert S. Siegler's group at Carnegie Mellon University and Elsbeth Stern's research group at the ETH Zurich before starting his own research group at the University of Trier.

Bob Siegler
Teresa Heinz Professor of Cognitive Psychology, Carnegie Mellon University, &
Director, Siegler Center of Innovative Learning, Beijing Normal University

Dr. Robert Siegler has written 9 books, edited 6 others, and authored more than 250 articles, monographs, and book chapters. His research focuses on how children learn mathematics and how theoretical understanding of mathematical development can be applied to improving that learning. His research led to the prediction, confirmed by subsequent research, that playing certain numerical board games yields broad, rapid, and enduring gains in preschoolers' and elementary school children's numerical understanding, particularly for children from low-income backgrounds.

Dr. Siegler's contributions have been honored in many ways, including being awarded the American Psychological Association's Distinguished Contribution Award in 2005, serving on the U.S. National Mathematics Advisory Panel from 2006-2008, election to the National Academy of Education in 2010, heading the development of a Practice Guide on fractions learning for the U. S. Department of Education in 2010, being appointed Director of the Siegler Center for Innovative Learning at Beijing Normal University in 2012, and election to the Society of Experimental Psychologists in 2015.
