Yeook Arrington received her Doctoral Degree in environmental engineering in 2002 from Illinois Institute of Technology. Yeook joined Particulate Solid Research, Inc (PSRI) in late 2006 as a research engineer. In early years, she started working on particle characterization, jet cup attrition, and fluidization characteristics with many different types of materials. Yeook also worked on one of technical programs for a few years focusing on particle attrition in fluidized bed-cyclone system for jet attrition and cyclone attrition. Based on this knowledge, Yeook had an opportunity in teaching a section of particle attrition in PSRI’s technical seminar to industrial engineers from all over the world for a couple of years. Over the years, Yeook gained the capabilities in operating small-to-large-scale cold flow units as well as troubleshooting in unit operations. More likely she has experienced in the area of fluid-particle systems such as fluidized beds, circulating fluidized beds, loop-seal type cyclone dipleg, risers, and segregations.    

Yeook earned her BS in environmental science from Kyung Hee University in South Korea in 1989 and her ME in Environmental Engineering from Hanyang University in South Korea in 1992. After receiving her master’s degree, she worked at National Environment Research Institute under Korea EPA for four years.
