Dr. Katharine Graf Estes, Principal Investigator - Lab Director

Infants are immersed in a world of immense complexity, yet they display knowledge of the people, objects, actions, and sounds in their environments very early in life. My research explores the mechanisms that support this early learning. In particular, the ability to detect statistical regularities may play a fundamental role in how infants learn about a highly complex, highly salient aspect of the auditory world: language. Infants become especially attuned to regularities in the sound patterns of the ambient language, including its phoneme distinctions, sound combinations within words, and its cues to word boundaries in fluent speech. Thus, when infants begin to understand and produce words, they do not start as a blank slate. I am investigating how infants learn from statistical regularities in the language they hear and the nature of what they learn.

Erica Verde, Graduate Student

I am a third year doctoral student in the developmental area in the psychology department. A simultaneous English-Spanish bilingual originally from Miami, I hold a bachelor's degree in Psychology from the University of Miami and a master's degree in Linguistics from Florida International University. Before joining the Language Learning Lab, I managed an infant language lab at Stanford University under Dr. Anne Fernald, as well as the ISI bilingual language processing lab under Dr. Paola Dussias at the Pennsylvania State University. I am broadly interested in lexical and semantic acquisition and processing in both monolingual and bilingual populations. In particular, I hope to explore the role of statistical learning in these processes and how variability in the input affects infants' ability to recognize meaningful language features.

Danielle Bucks, Lab Manager

I am a junior transfer student at UC Davis studying Psychology with a minor in Human Development. Starting at an early age in life, I have always had an interest in children and how their minds can be so brilliant at such a young age. Working with or around children has always been something I love, and from my time at Davis, learning about the progression of development in children has made my fascination grow even stronger. I was motivated to join the Language Learning Lab to further advance my knowledge about not only the development of children, but specifically the growth of language in infants. I hope to use my experience and forthcoming encounters in this lab towards my future career working with children. Outside of academics I really enjoy cooking, watching Netflix, being outdoors and hiking, going to the gym, and being around friends and family.

Andrea Ramirez, McNair Scholar

I am a fourth year student at UC Davis double majoring in Psychology and Spanish with a minor in Chicano/a Studies. I’m originally from Woodland, CA, where I started to work with children that had a learning disability. As a bilingual person myself, I became interested in the developmental capacities that children have as they grow older, especially those who speak more than one language. I decided to join the Language Learning Lab because I believe it will allow me to gain knowledge about the topic of infant directed speech in bilingual children. I am currently working as a Spanish tutor at the Spanish for Spanish Speakers Program at the Department of Spanish and Portuguese; I’m also a McNair Scholar.

Carolyn Ta, Undergraduate Research Assistant, Lead of Business Communications

I am a third year undergraduate student at UC Davis majoring in Neurobiology, Physiology and Behavior, with a minor in Education. I have a passion for working with kids, which originated from teaching at a local summer school over the past five summers. I am amazed at how children, especially infants, can absorb and understand so much information in such a short amount of time. I joined the Language Learning Lab to work with children in a new research environment, as well as to learn more about this process of understanding information. I plan to go to medical school and pursue my goal of becoming a pediatrician. I think the lab is a great experience that will make my passion for working with children stronger and help make me a better professional. Outside of lab, I enjoy running, eating, and spending time with family
and friends.

Madeline Wenner, Undergraduate Research Assistant, Lead of Media Platforms

I am a fourth year pre-med student at UC Davis majoring in Biochemistry and Molecular Biology and minoring in Classics. Taking Latin classes and comparing them to my knowledge of English and Spanish recently sparked my interest in languages, the history and development of languages, and how they are learned. There are many fascinating complexities in the ways different groups of people choose to communicate, and I hope to continue learning more about linguistics through this lab and through my classes. I also plan on becoming a doctor; my love for children has led me to consider Pediatrics or Obstetrics as a specialty in order to spend time helping kids. I am excited to work with children while doing research here and learn from how kids interact with the world around them. I hope my time spent in this lab will help me to become a better health-care provider someday, and a more well-rounded student.

Summer Zhu, Undergraduate Research Assistant, Lead of Visual Data

I am a second year international student at UC Davis majoring in Psychology with a minor in Education. I was born and raised in Shanghai, which is a typical bilingual city for Shanghai dialect and Mandarin. I came to United States at the age of 14 with the aspiration to broaden my world perspective, and this experience of overcoming language barriers made me really interested in Education and Linguistics. I am attracted by the process of how infants learn two languages simultaneously and by the cognitive ability of a child to see environmental patterns. Joining the Language Learning Lab can help me gain practical research experience, which will directly relate to my future career as an early childhood educator. I also had several experiences of working with children before. Other than my passion for language and
children, I enjoy hiking and playing badminton.

Christina Chin, Undergraduate Research Assistant

I am a third year undergraduate student at UC Davis majoring in Psychology with a minor in Human Development. My passion for Developmental Psychology is rooted in my enthusiasm both for mental health and for learning disabilities, which stems from my own experience growing up with a learning disability. I am fascinated with not only how children infants learn differently but also how quickly they learn and adapt to the world in different ways. It also captivates me how capable babies are of learning, especially language, in ways that we as adults are not. I plan on taking what I learn from my experience in this lab to pursue a PhD in Developmental Psychology and hopefully achieve my dream of being a child and adolescent clinical psychologist. During my free time, I enjoy climbing at Rocknasium, playing piano, and going out for a good day of hiking.

Natalie Ho, Undergraduate Research Assistant

I am a fourth year student at UC Davis majoring in Neurobiology, Physiology, and Behavior and minoring in Psychology. I grew up speaking English and Vietnamese at home and learning Spanish at school. My love for working with children began from my huge family where I experienced babysitting, educating/mentoring, helping with homework, and playing with my little cousins and brother. It is because of my love for the younger demographic that inspires my future career goal in pediatrics! I am extremely excited to be a part of the Language and Learning Lab because I will get to witness infants absorb new information and process language through a scientific perspective. I am also interested in how different environments and varying teaching methods can help children learn effectively.

Jerice Banola, Undergraduate Research Assistant

I am a second year undergraduate student at UC Davis, majoring in Neurobiology, Physiology, and Behavior. I was originally born in the Philippines, making Tagalog my first language. However, my family eventually moved to America when I was an infant, causing me to lose my ability to speak Tagalog and learn English. Learning how bilingualism develops in infants is something I’m very interested in learning about and a big reason why I joined the Language Learning Lab. I am very excited to learn more about the progression of languages in infants and also the growth of myself through this lab, hoping to use what I learn in my future endeavors.

Delphine Golly, Undergraduate Research Assistant

I am a third year undergraduate student at UC Davis majoring in Cognitive Science with a minor in Psychology. My parents are both from Ivory Coast, so I grew up in a bilingual household of English and French. All of my siblings were exposed to French at different points in our childhood/adolescence, which has led to some speaking fluent French and others, including myself, barely remembering the basics from memory. Being in this position has led to a great interest in how the ability to learn languages processes and changes with and without environmental and cultural influences, and I think the Language Learning Lab is the perfect place to explore this idea! In the future I plan to pursue a graduate degree in hopes of becoming a clinical psychologist researching the development of mental illnesses throughout one’s life. In my free time I enjoy going to the gym, listening to music, shopping, and being with friends and family.

Cindy Ceja, Undergraduate Research Assistant

I am a third-year student double majoring in Psychology and Communications. My interest in language development began when I was enrolled in an Introduction to Linguistics course. Instantly, I was enthralled by how humans have the capability to acquire and use language. Also, as a simultaneous English-Spanish bilingual individual, I would like to expand my knowledge on bilingualism and its effects on how children can learn to identify new sounds and words. I plan on becoming a Child or School Psychologist as I am interested in helping to guide children as they continue to develop emotionally, physically, and psychologically. Thus, I hope to help children develop in every aspect of their lives alongside helping them cope with any foreseeable situation. Outside of academics, I enjoy cooking, visiting art museums, and checking out new cafés.

Sofia Ledesema, Undergraduate Research Assistant

I am a second year student at UC Davis majoring in Human Development and minoring in Chicano Studies. I grew up in a Bilingual household, my grandparents speak Spanish and my parents speak English. I worked at a clinic over the summer that primarily serves the LatinX population and witnessed how a patient's experience is heavily impacted on whether their provider speaks their language. I hope to use the knowledge I gain from the language learning lab to work as a social worker in bilingual communities.

Alexis Elliott, Undergraduate Research Assistant

I am a fourth year Human Development major at UC Davis. I have grown up working with children who have difficulties learning to speak, or who use sign language to communicate. It has always amazed me at the versatility and importance of language. I look forward to using what I learn from this lab in my future career as a nurse.

Jinlin Xie, Undergraduate Research Assistant

I am a fourth year undergraduate student majoring in Psychology and minoring in Education. My native language is Chinese, and I started learning English as I got older. The difficulties of learning English have prompted me into studying language development. I remember after I learned that “-er” can be used to make nouns mean someone who is performing the action, I called a chef “cooker”. It was an embarrassing experience, but also caused me to become interested in how categorization may influence and facilitate language learning. I also love taking care of kids and I want to work in a pre-school setting in the future. Working in the Language Learning Lab would be an ideal setting for me to explore every aspect I am interested in. I enjoy hiking and going to the gym in my spare time.

Colleen Hernandez, Research Assistant

I have recently finished my MS in Child Development at University of La Verne and am applying to a PhD in Developmental Psychology at UC Davis and am a certified early childhood educator. I grew up speaking English and learning Spanish in high school, then in college I studied several years of Japanese. While I was living in Japan teaching English for 3 years, I became interested in learning more about the mechanics behind how children acquire a second language. I became an early childhood educator upon returning to the US and gained experience with infants and toddlers as well as bilingual preschoolers. While raising my own two daughters, being involved in their linguistic development day by day has been exciting and very informative. I am interested in early word acquisition, cognitive development, semantic learning, how parents' speech might affect learning, and the mechanisms involved in multilingual learning. I look forward to learning more about the research process.

Kimberly Francis, Undergraduate Research Assistant

I am a fourth year undergraduate student pursuing degrees in both English and Linguistics with a minor in Education. Throughout my academic career, I have been able to explore my passion for education and experience an immeasurable amount of joy working closely with children in a variety of settings. I am excited to further my understanding of cognitive and linguistic implications upon language processing/development and apply the skills I will acquire through this position to my future career as a Speech-Language Pathologist.

Ann Cheng, Undergraduate Research Assistant

I am a fourth-year undergraduate student at UC Davis majoring in Psychology and minoring in Human Development and Education. I chose to join the Language Learning Lab because I grew up bilingual. I am interested in learning and researching about the cognitive development of children and being able to apply what I learned to my future career. I am also a member of the Social Environment and Stress lab where I learn about how children from different family backgrounds react to stressful situations. In my free time, I like to explore new coffee shops, bookstores, and play the piano.
