Post-Doctoral Researchers

Pablo León-Villagrá, Ph.D.

Post-Doctoral Researcher

I am a postdoc in the Computational Cognitive Development Lab at Brown University. During my stay at Dr. Buchsbaum’s lab I’d like to explore how children form representations of the world around them and how these representation allow them to perform rapid generalization and transfer. Outside of work I like to play chess, read and try out new recipes.

Graduate Students

Caiqin Zhou

Ph.D. Student

I’m a second-year Phd student in Cognitive Science. I’m broadly interested in children’s active learning and exploration and their causal reasoning. My research uses both behavioral and computational methods to explore these topics. Before coming to Brown, I studied children’s prosocial behavior in Dr. Felix Warneken’s lab and children’s Theory of Mind in Dr. Julian Jara-Ettinger’s lab. I received my bachelor’s degree in Psychology and Economics from Wellesley College. Outside of work, I enjoy watching medical and crime TV shows and taking long walks.

Carly Fisher

Ph.D. Student

I am a first-year graduate student in the Brown Dog Lab pursuing a Ph.D. in Cognitive Science. I previously worked with the Boston College Canine Cognition Center under the advisement of Dr. Angie Johnston. While there, I received a B.S. in Psychology and a M.A. in Developmental Psychology. I research multiple species (e.g., domestic dogs, Australian dingoes, & human children) to examine how domestication has influenced dogs’ social and physical reasoning skills. When not in the lab, you’ll find me baking, crocheting, or walking my new dog Copper!

Sarah Kiefer

Ph.D Student

I am a second-year Ph.D. student in the lab. I graduated from Arizona State University in 2019 with a B.S. in Psychology. Prior to Brown, I worked as a research coordinator at the Southwest Autism Research and Resource Center (SARRC) and then as a lab Manager of the Emerging Minds Lab at Arizona State University (PI: Kelsey Lucca). My research examines children’s early learning through exploration, causal reasoning, and effort allocation. When I am not in the lab, I enjoy rock climbing, watching films, and cooking.

Madeline Pelgrim

Ph.D. Candidate

I am a fourth-year doctoral candidate in the Cognitive, Linguistic, & Psychological Sciences Department here at Brown. I completed my Bachelor’s at the University of Toronto where I studied Biology & Psychology. My research focuses on how dogs learn about and interact with the world around them, particularly in their interactions with their human companions.

Rebekah Gelpi

Ph.D. Candidate

I am a Ph.D. candidate currently studying at the University of Toronto. I am particularly interested in the differences between children’s and adults’ learning in social environments, and whether these differences reflect strategies that children and adults are uniquely suited to using. Outside of the lab, I love seeing new films at TIFF and trying out new recipes from the Great British Bake Off.

Zory Zhang

Ph.D. Student

I am a 1st-year graduate student in the lab. I am intrigued by how children eventually learn so much about the world so quickly without even realizing they are learning (e.g., concepts that “carve nature at its joints”, the specific ways agents are driven by their beliefs and desires, or their native languages). I’m particularly interested in the puzzle of why children are sometimes more flexible learners than adults, readily revising their beliefs, yet at other times seem to arbitrarily firmly believe. Besides research, I like to cook, learn figure skating, ride my bike, watch shows, and occasionally do drama-related stuff. My website: https://zoryzhang.notion.site

Then, I worked as a joint Lab Coordinator for Wesleyan University’s Cognitive Development Lab and Reasoning and Decision Making Lab. I am interested in child social cognitive development. In my free time, I enjoy reading, cooking, and being outside.

Hi y’all! My name is Ava, and I am a second-year undergrad studying both psychology and economics. I have focused a lot on animal behavior in my psych courses and hope to continue to integrate it into my concentration. I am excited to be working in the lab as I not only love animals but feel I am getting to accomplish some academic goals as well. Additionally, I love to travel and this past summer I did service work in Kibwezi, Kenya, and was lucky enough to go on safari.

Bryson Boone

Volunteer Research Assistant

Hi friends! My name is Bryson, and I am a sophomore here at Brown studying Biology & Psychology, on a pre-med track. A few fun facts about me: 1) I am a Swiftie! Top album is, of course, folklore, and my top song is “this is me trying” 2) Survivor is my favorite reality TV show and 3) I love Panera! Before I came to Brown, I worked with animals regularly in cat shelters, through my pet care business, and via FFA (Future Farmers of America). Needless to say, I have always loved working with animals, but I am super excited to be able to work with dogs under this amazing research team.

Dorinda Kyeremateng

Volunteer Research Assistant

Hello! I’m Dorinda, a senior studying Computer Science at Brown and Industrial Design at RISD. I’m excited about combining these backgrounds to do user experience research and design within educational spaces. I especially enjoy working with first-generation and low-income students like myself, and it’s been wonderful helping high school students with college admissions as a peer advisor. Outside of school, I enjoy being with friends, journaling, and working through all sorts of puzzles — from jigsaws to Wordle!

Undergraduate Research and Teaching Award Student

Hi! I’m Kaylin, a sophomore planning to concentrate in English at Brown, and one day I hope to become a pediatrician! I’m particularly interested in the intersection of literature and science; I think literature is one way that we make sense of humanity, and I can’t wait to explore the psychological side of human learning and behavior. I’ve always loved working with kids, and I’m excited to continue that in the lab. In my free time, I like visiting libraries, baking, watching movies, and traveling!

Lily Hong

Undergraduate Teaching and Research Award Student

Hey! I’m Lily, and I’m a sophomore at Brown concentrating in Biology (EEOB Track) and maybe Philosophy (we’ll see!). I’m super interested in seeing how interactions between organisms shape their evolutionary paths. In the past, I’ve studied both intra- and interspecies interactions in ocellated wrasses and pederson cleaner shrimp respectively, and I’m excited to see how this translates to dog-human relationships! In my free time, I love basking in cool summer nights, chasing philosophical rabbit holes (aka conspiracy theories) with friends, and bingeing bad rom-coms.
