Prof. Casey Lew-Williams studies how babies learn, with a particular focus on language and communication. He is interested in how babies learn and generalize patterns, how toddlers efficiently process what their parents say, how home language experience shapes learning, and why some children learn more easily than others. He studies various populations — including children learning two languages and children growing up in poverty — to ask questions about the foundations and high-stakes consequences of early learning.

Alyssa is commited to better understanding children's dynamic, diverse language experiences. Broadly, she is interested in exploring how aspects of children's everyday environments support early language learning and communication. Alyssa has previously worked with Dr. Susan Goldin-Meadow and Dr. Marisa Casillas at the University of Chicago, and Dr. Meredith Rowe at the Harvard Graduate School of Education. Outside of the lab, Alyssa enjoys caring for her tree frog, baking, and taking photographs.
Ph.D., 2011 Jerusalem
Liat has completed her PhD on learning and motivation in early childhood. At Ariel Knafo-Noam’s Social Development Lab in Jerusalem she learned how to use behavioral genetics to investigate the interplay of nature and nurture in the development of prosocial behavior and the emergence of values. This work has ignited Liat’s keen interest in the question of how knowledge is transmitted across time, from generation to generation, and how it travels across space, via various forms of media such as books, audio recordings and videos. To do so, Liat is combining natural and realistic experimental set-ups with neuro-imaging approaches.

Ph.D., 2023, Cornell University
Steven studies the perceptual mechanisms that guide early communicative and language development. He is particularly interested in parent-child interaction and children's active role in shaping what is relevant for them to learn. In what ways do children use their own behaviors to spark interest in and continued learning about the social world throughout early development? If he's not in the lab, Steven is probably spending time cooking outside or taking his retired racing greyhound, Wendy, for a walk.
B.S., 2014, University of Tennessee

Ph.D., 2022, University of Miami
Stevie's interests broadly revolve around how features of children’s everyday environments and contexts influence their social interactions with caregivers. In her dissertation work she used automated measurements of children’s language and movement in inclusive preschool classrooms to understand how language interactions differ across activity contexts for children with and without developmental delays. In her free time, Stevie enjoys practicing yoga, trying out new cooking and baking recipes, and wandering around Philly with her dog Lula.

Jessica is interested in how infants’ attention and learning is influenced by features of their everyday environment. In her dissertation work she measured changes in infants’ pupil diameter to investigate how caregivers’ modifications to infant-directed action (such as increased exaggeration and repetition) impact infants’ attention during novel object demonstrations. When she’s not working, Jessica enjoys practicing yoga, taking dance classes, and spending time with her husband and their three cats.
Nicole is interested in all things language- how it is learned, how it is used, and what this tells us about the brain. Nicole received her B.A. in Cognitive Science at University of Michigan (go blue!). Since then, she has worked as a lab manager for the Gelman Conceptual Development Lab and the Language Learning and Multisensory Brain (LLAMB) Lab, working closely with Susan Gelman, Richard Aslin, and David Lewkowicz. Outside of the lab, Nicole can be found taking long walks with her fur baby (Theo), cooking, or binge watching a series in record timing.

Fueled by his curiosity for the magic in the world, Jonathan plans to examine how the inherent mechanisms for learning and memory may have evolved, developed, and interacted with one another to give rise to complex human cognitive abilities. Jonathan previously worked with Dr. Brooke Macnamara at Case Western Reserve and later managed the Turk-Browne lab at Yale University. Besides research, Jonathan is a competitive powerlifter and enjoys exploring new brunch spots with his dog.

Crystal is interested in how children use various (social, environmental) cues, such as speaker information or visual variability, to learn words. Crystal has previously worked in the Language Development Department at the Max Planck Institute for Psycholinguistics in the Netherlands, the Harvard Lab for Developmental Studies, and Johns Hopkins Laboratory for Child Development. Outside of the lab, she likes to paint and draw, watch stand-up, and bake desserts.
B.S., 2016, Stanford
Mira is interested in the role of the social cues surrounding language and communication early in life, such as facial expressions and prosody. She is especially excited to explore the different time-scales at which these cues act - from subsecond moments in a single interaction, to the accumulating statistical information over longer periods of time. Outside of the lab, Mira can be found on long morning walks, painting or trying to find every single jazz concert in the area.

Adele Goldberg has been a professor of psychology and linguistics at Princeton University since 2004. Her research emphasizes the role of a learned network of pairings of form and function constructions in language. Her work has focused on the role of statistical and functional factors in an effort to explain our creative but constrained use of language in typical and atypical populations, and in child and adult learners. She is the author of Constructions: a construction grammar approach to argument structure (1995) Constructions at Work: the nature of generalization in language (2006) Explain me this: creativity, competition and the partial productivity of constructions
Dr. Tania Lombrozo investigates how young children and adults learn and reason about the world, using the conceptual tools of analytic philosophy and the empirical tools of experimental psychology. Current research in her lab focuses on questions such as: Why are we so motivated to explain the social and physical world around us? What prompts us to seek explanations, and what are the effects of explanation-seeking on subsequent learning? How do our intuitive theories about the world shape the way we learn and make decisions? She received Bachelor’s Degrees in Philosophy and Symbolic Systems from Stanford University, and PhD in Psychology from Harvard University. Prior to joining the faculty of Princeton University in 2018, she was a faculty member at the University of California, Berkeley. In addition to being an affiliate of the BabyLab, Prof. Lombrozo directs the Concepts and Cognition Lab
