Nick Bisbee | 6th year PhD student

Humans quickly learn to use physical objects, symbols, and icons to manipulate the world around them. In what ways are we built for tool usage and how do we create systems of intangible tools like numbers or logic? How does our curiosity lead us to learn about so many systems (eg. block tower physics, Algebra, Game of Thrones politics) that we may not see a need for? I study what bounds our learning and what inspires it – with an emphasis on object representations and how they interact with our desire to share our conceptualizations.

Peter Mazalik | 5th year PhD student

I am interested in the developmental trajectory of our logical capacities and the internal structure of infants’ representations. Currently, I am researching how children understand and contemplate possibilities and how infants represent change as a constant feature to determine individuation.

I graduated from the University of Michigan in 2023 where I majored in Biopsychology and Cognitive Science with a Philosophy focus. I think it is fascinating that infants and young children can reason about their environment using their primitive expectations about the way the world works. How does this early knowledge develop? I am studying how surprise and curiosity drive children’s explanation seeking, recognition, and generation. I am also interested in the cognitive and developmental origins of causal-reasoning abilities.

I am always amazed at how much babies know! This intrigues me to explore how early cognition is structured to store that knowledge. Currently, I’m researching how infants update their representation of objects and others’ mind. I’m also interested in how they utilize the knowledge they possess to guide their own information seeking behaviors. Outside the lab, I’ve been trying to apply my knowledge to understanding my cat’s behavior – an ongoing project I’m really passionate about!

Justine Griego | 4th year PhD student
jgriego2@jhu.edu

I graduated from Emory University in 2021, with a double major in Linguistics and Psychology. My past research experience in psycholinguistics, comparative ecology, and neuroscience piqued my interest in the origins of the human mind. Currently, I work with the Social & Cognitive Origins Laboratory and the Laboratory for Child Development to dive into new questions on the evolution of the mind: how does language influence other mechanisms and capacities of cognition? How does perception differ between species? What is the structure and function of thought? And how well do contemporary philosophies of the mind answer these questions? If you are a dog, ape, or baby, or you have a friend who is, feel free to reach out to hear more! 

Liz Kim | 1st year PhD student
dkim289@jhu.edu

I graduated from Emory University in 2023 with a major in Psychology and a minor in Sociology. I then completed my master’s degree at the University of Chicago, where I discovered my interest in developmental psychology. How do early learners so rapidly and effectively make sense of the world? I am particularly interested in infants’ ability to make rich inferences that go beyond what they directly observe, whether about physical objects or social agents. I am excited to begin my PhD and continue exploring these questions through the lab’s ongoing work on surprise-induced learning!

Undergraduate Students

Lauren Fang

I am a senior at Johns Hopkins University double majoring in Public Health Studies and Natural Sciences with a minor in Psychology. My experiences as an older sister, coach, and volunteer with underserved families sparked my passion for working with young children. This interest led me to the Baby Lab, where I can explore the mechanisms of childhood cognitive development. I am particularly interested in how children perceive the world around them and how surprise can play a key role in learning. I hope to carry the insights and experience I gain from this lab into my future career as a physician.

Yukang Han

I am a senior and transfer student at Johns Hopkins University, majoring in Neuroscience. Previously, I studied Clinical Psychology at the University of California, San Diego. I have always been passionate about understanding what happens inside the human body, especially at the neuronal level. My interests focus on how the conscious system develops and how early childhood development influences individuals throughout life. I’d love to combine my backgrounds in neuroscience and psychology to explore the development of consciousness and explore my future career path here. 

Jessica He

I am a junior at Johns Hopkins University, from San Jose, California, majoring in Neuroscience and Psychology. I have always loved interacting with babies and children. I worked as an after-school tutor, not only helping children with their homework, but also finding ways to have fun. I am also the older sibling, and I often reminisce about the hours spent drawing and playing with my younger sister. Babies and children are curious, expressive, and deeply intuitive, seeing and knowing more than we give them credit for. I am especially interested in core knowledge systems in children and how these systems enable infants and children to learn and how learning affects these systems. As an aspiring clinical neuropsychologist, I believe my interactions with babies and children can further my understanding of the brain and how it develops, hopefully enabling me to better assess and treat individuals with brain disorders and neurological conditions. 

Chloe Lee

I’m a current junior at Johns Hopkins University planning to major in public health and psychology. I have always believed babies were a lot more complex than what we initially thought so I joined this lab to understand and explore my curiosity. I’m especially interested in research involving children with ASD, as I have a great deal of experience working with them.

Athina Ramphal

I am from New York, and I am a senior at Johns Hopkins University majoring in Psychology. I am a Research Assistant in the Child Development Lab, and my interests focus on how infants make choices and how those choices are influenced by the people around them. By examining the “why” behind early decisions, I aim to understand the mechanisms of learning and human behavior across development. I also hope to apply these insights to my current work with youth in the community and to other endeavors at the intersection of child psychology and the justice system.

Caeli Robinson

I am a senior at Johns Hopkins University majoring in Cognitive Science, with focal areas in Neuroscience and Cognitive Psychology. I have had the opportunity to work with children in a variety of settings, from being a speech therapist at a school for children with diverse learning needs to volunteering in medical clinics across Asia and coaching field hockey and squash. These experiences sparked a deeper curiosity about how children think and make sense of the world around them, ultimately leading me to the Baby Lab! I am especially interested in how developing minds shape the way children interact with and learn from their environment. After graduation I hope to pursue a career as a physician, where I can continue working with children.

Yosef Schnitzer

I am a sophomore at Johns Hopkins University from Tucson, Arizona, studying Neuroscience and Critical Diaspora Studies. Understanding the science behind learning is what intrigued me about the Lab for Child Development. Much of my academic interests lie in education: the psychology, sociology, and neuroscience behind it. I’m interested in how difference affects learning—i.e., neurodivergence and systemic injustice in education systems—and the various methods—pedagogy, neuropharmacology, educational policy—to respond to these differences. My work at the LCD investigates how learning occurs in the first moments of life through language acquisition. This research will provide a foundation in learning science to examine neurological and sociological educational outcomes. 

Aliza Tharani

Hi there! I am a junior at Johns Hopkins, majoring in Neuroscience and minoring in Visual Arts. I call Dallas, Texas home and love my role as the oldest sister in the family. My love for working with kids stems from doing JMC Camp Mosaic as a counselor and First Aid team member over many summers. I teach workshops on fun neuroscience topics for elementary school kids. I am especially excited to explore the core knowledge base we come into the world with and where the boundary of nature vs. nurture blends in child development through upcoming research in the lab. I aspire to be a pediatric neurosurgeon in the future and hope to bridge gaps in care for underserved populations within the field. 

Sammy Vidomlanski

I am a junior at Johns Hopkins University from New York, majoring in Psychology and Near Eastern Studies. I’ve always loved working with kids, whether in academic settings through tutoring or as a camp counselor. I am particularly excited to explore cognitive development in children through the Baby Lab and learn more about how children understand and make sense of the world around them. I hope to pursue a career in clinical psychology, where I can continue working with and supporting children and adolescents.
