Hi. I'm Jo and I research brain networks.

I am a member of the BNBL run by prof. Rick Betzel at Indiana University - Bloomington. I am enthusiastic about brain networks and how they can be used to model and test interesting questions - which can include quite a broad range of things! In short, my research interests and can be summarized as the following keywords: brain networks; network-based idiosyncratic features; higher-order functional brain interactions; graph theoretical applications; development; aging; network-based cognitive/behavioral/disorder prediction


Academic background
I am currently doing my dual PhD at Indiana University - Bloomington (FA2019 - present) in the Psychological and Brain Sciences Department and the Cognitive Science Program with my research focus on computational and cognitive neuroscience. I also did my MSc in Neuroscience at King's College London (Meritus) with Dr. Marco Catani. My master's thesis was on the structural connectivity of the visual occipital fasciculus and it's potential influence in human language abilities. As my undergraduate program, I studied at Sogang University and received a B.Sc. in Biology and B.Eng in Biotechnology (Magna cum Laude).


Facts about me?
(a) I enjoy spending time with my 18 month old boy S.P.
(b) My handsome cat - Hoochu - was adopted from an animal shelter
(c) I also enjoy creating art/paintings, which help me alleviate stress and express my inner creativity (exhibit 1: A Borderless Mind)
(d) I used to play competitive badminton (1st place in municipal high-school tournament women's singles) and Korean traditional percussion as the drummer (Samul-nori; 3rd place in provincial competition)
(e) Favorite genre of movies: horror (i.e. Dark Water) and drama (i.e. Old Boy, Oasis)
(f) Find out more when you meet me in person!
