Dr. Ioulia Kovelman : Principal Investigator

Dr. Ioulia Kovelman


Principal Investigator

Dr. Kovelman is a developmental cognitive neuroscientist, and an Associate Professor of Psychology, interested in how bilingual children learn language and literacy. Her research program includes both behavioral as well as brain imaging studies of language and literacy acquisition, in typically developing children, as well as children with learning difficulties.

Dr. Xiaosu (Frank) Hu : Research Investigator

Dr. Xiaosu (Frank) Hu


Research Investigator

Frank is a research investigator at the Center for Human Growth and Development. He received his Ph.D. at Pusan National University (Korea) in Cogno-Mechatronics Engineering. His research interests include biomedical signal processing, fNIRS/EEG based brain signal detection and brain engineering (BCI). His applied work uses fNIRS to study human daily behavior accompanied brain responses, including pain evoked human brain response, different mental states while people are driving, and the pediatric brain responses during language acquisition.

He currently works for Language & Literacy Lab and Headache & Orofacial Pain Effort Lab as a Research Investigator.

Valeria Caruso : Research Investigator

Valeria Caruso


Research Investigator

Valeria is a research investigator at the Center for Human Growth and Development. She received her PhD in Cognitive Neuroscience at SISSA (Trieste, Italy) working on auditory perceptual learning. She has done research at Duke University concerning 1) how the primate brain encodes spatial visual and auditory cues that help localize objects and guide movements, and 2) what encoding mechanisms allow processing multiple cues simultaneously and 3) whether similar information encoding mechanisms support language perception in humans (ongoing research). She is also interested in looking at language processing and acquisition from a developmental perspective.



Research Staff

Isabel Hernandez : Bilingual Lab Manager

Isabel Hernandez


Bilingual Lab Manager

Isabel has been working as a research assistant and as a principal recruiter for the Language and Literacy Lab. She received her bachelor’s degree from Universidad de las Americas-Puebla UDLAP (Puebla, México). She is interested in understanding the cognitive, language processing and brain development, especially in bilingual kids. As a research assistant, she conducts behavioral assessments as well as data entry, data collection and data analysis. As a recruiter, she plans and coordinates participant recruitment, determines their qualifications by performing phone interviews with the candidates, maintains accurate records of interviews, and safeguards the confidentiality of the participants. In addition, she is very experienced in building strong, long-term and mutually beneficial relationship between the participants and the lab.
