Hyun Joo Yoo first joined the lab as a research volunteer in 2013. She previously had received her Ph.D. in Cognitive Psychology from Sungkyunkwan University in Korea. Since joining the lab, she has coauthored around 15 research papers, with a focus on the relationship between heart rate variability (HRV) and brain structure (see Yoo et al., 2018; Yoo et al., 2022). Recently, she led a lab team effort to curate data sharing of results from a clinical trial testing effects of HRV biofeedback on brain structure and function. She was recently promoted to a Research Scientist position. Congratulations Hyun Joo!
