Principal Investigator


Prof. Lauren Emberson
Lauren is broadly interested in how experience shapes development and studies this process through the lens of perceptual and learning abilities. How do these abilities interact and fuel developmental changes? Lauren is also the co-founder and co-director of the Princeton Baby Lab.

Post-Doctoral Researchers

Sagi_Jaffe-Dax_photoDr. Sagi Jaffe-Dax
Sagi is interested in how infants learn to predict upcoming events and perceive them efficiently. To reveal the underlying mechanism of these processes, Sagi uses both behavioral, computational and neuro-imaging approaches.

IMG_2017Dr. Yaelan Jung
Yaelan is broadly interested in how the brain organizes complex sensory inputs from our blooming and buzzing world. Her previous work focused on categorization and statistical learning as organization principles of the brain. In Baby lab, she is very excited to explore how little humans manage this challenge, and how this might differ from adults given their ongoing maturation of the brain and their limited experience in the world. In her free time, Yaelan enjoys practicing yoga, swimming, cooking, and starting a new knit/crochet project (and never finishes them).

Graduate Students

IMG_8181Felicia Zhang
Hi! I’m a fourth year graduate student in the Baby Lab. I research how young infants use prediction error (i.e. wrong predictions) to learn information from the world. My research uses eye-tracking, with a specific focus on pupillometry (i.e. the measurement of pupil size) with computational modelling.

Tracy Reuter
My research investigates language processing, prediction, and learning. Given the incredible complexity of language, how do we finish each other’s… sandwiches? (And what happens when our predictions are wrong?)

Sori received her B.S. in Psychology in University of Minnesota. Sori is excited to use fNIRS to investigate the mechanisms through which babies use their experiences to engage in top-down processing on visual perception. She is most interested in exploring functional connectivity in the infant brain to understand the inception and early development of complex functional networks.             Personal Website

Senior Thesis Students

AliceWangAlice Wang
Alice Wang (Class of 2019), from Palo Alto, California, is currently concentrating in psychology with a visual arts certificate. She is interested in the role education plays in child development, specifically regarding how visual and acoustic stimuli influence learning. In her spare time, Alice can be found (break)dancing with Sympoh, writing old-fashioned letters, or naming inanimate objects.

fernandaFernanda FernandezVV
Fernanda Fernandez (Class of 2019) is a Neuroscience major from Rutherford, New Jersey who loves taking care of and working with children. Her senior thesis research focuses on infants’ visual perception—how infants can use predictive sounds to guide their interpretation of an ambiguous picture. Outside of the lab, she is an EMT for the Princeton First Aid and Rescue Squad in town and a tutor at McGraw. In her free time, she loves going on runs, playing guitar, or spending time with friends. After Princeton, she plans to attend medical school and become a physician.

Staff Members

Anna_website_photoAnna Herbolzheimer
Anna earned her B.A.S. in Psychology and Statistics at the University of California, Davis. While there, she used eye-tracking to study infant cognitive development with Dr. Lisa Oakes. She is excited to continue to learn about infant development using neuroimaging at the Baby Lab! In her free time, Anna enjoys reading and exploring New York City.


Annie Schwartzstein
Annie received her B.A. in Psychology and Political Science from the University of Minnesota in the Twin Cities. While at Minnesota, Annie assisted with political and social psychology research under Dr. Eugene Borgida, focusing on metasterotype activation between conservatives and liberals. Annie is very excited to work with the families and babies here in the Baby Lab! When not managing the lab or researching, Annie enjoys baking for friends, running around the beautiful streets of Princeton, and trying out new restaurants.
