Materials/Analytical Chemist
PhD in Chemistry
Jae Jin Bang
Trained in Chemistry, now working on solid-state batteries.
As my side project, I am trying to learn
more about data science to complement my existing skills and because it is fun!
The main purpose of this website is to keep me motivated in my studies and to track my progress .
Education
2018
Purdue University (USA)Ph.D. in Chemistry
Graduated with focus on Analytical Chemistry
Introduced the sitting phase assembly of photopolymerizable phospholipids as an alternative lithographic technique to construct sub-10 nm chemical patterns on layered materials.
Established the group's protocol for scanning probe characterization (AFM, STM) of the interfacial nanostructures.
Developed strategies to template the deposition of functional materials including ultrathin nanowires and polymers on 2D surfaces using the amphiphilic chemical patterns.
2013
Seoul National University (S Korea)B.S. in Chemistry, Biological Sciences
Investigated the size-selective catalytic properties of nanoporous electrodes to improve the efficiency of fuel cells.
Studied the role of kinesin protein, Kif18a, at checkpoints during cell cycle in an attempt to identify tumor suppressors.
