Yoojin Jung



University of California, San Diego

October 2014 – June 2018

B.S., Chemical Engineering

G.P.A.: 3.545

Tohoku University

July 2015

Tohoku University Science Summer Program


Well-versed in Microsoft Word, Excel, VBA, PowerPoint, JMP, MatLab, Statistica, SQL, LabView, AutoCAD, and AspenPlus

Experience with FTIR, XRD, DLS, PFD, Lean manufacturing, and DMAIC methodology

Project Experience

Associate Research Scientist, ZPower, LLC

October 2018 – July 2019

Developed and executed DOEs to optimize production yield, formulation and manufacture, and storage and environmental conditions

Increased process yield by 15% by validating a process parameter change

Optimized raw material storage, increased product shelf-life, and decreased quality issues

Determined root cause of failures and provided recommendations for improvements and corrective actions

Managed and completed projects in accordance with project requests and established timelines to ensure project deadlines are met

Worked in multi-discipline teams with members of R&D, process improvement, electrical engineering, and operations to accomplish project goals efficiently and with good quality

Used software packages such as JMP, Statistica, and Microsoft Excel to analyze and interpret raw data; ran statistical models, such as an ANOVA, to ensure experimental results were statistically driven

Presented weekly within R&D meetings and monthly to CEO and other members of upper management

Undergraduate Research Assistant, Zheng Chen Energy Storage Research Group

October 2016 – June 2018

Improved the performance of coin cells by determining an optimal coating material percentage that positively affects the cell’s cycling stability, initial coulombic efficiency, and impedance

Presented on research pertaining to limiting the dissolution of manganese ions in LiMn2O4 batteries and increasing the stability of LiMn2O4 batteries to a group of colleagues

Certified proper lab procedure and lab safety as quarterly lab safety manager by organizing lab cleanings, ensuring proper chemical maintenance, and learning the SOPs for all equipment used within the lab

Student Process Engineer, Petroleum coke to sulfuric acid process plant, UCSD

January 2018 – June 2018

Determined the optimal flowrates of petroleum coke, sulfur, water, and oxygen to yield 100,000 tons of sulfuric acid per year assuming the flowrate of petroleum coke is just high enough for the energy released from its combustion to power the reactor

Utilized AspenPlus to simulate a petroleum coke to sulfuric acid process which included a mixer, supercritical water oxidation reactor, filtration system, and separation train

Used Microsoft Excel to create a cash flow analysis for a plant located in Carson, CA with a 30-year operation life; found an annual profit of about 10 million USD a year

Regularly met with client to provide excellent project proposal

Worked as team lead in a team of four chemical engineers to oversee team’s meetings, lay out a plan of action for each step of the project, and consult with the client and liaison

Student Researcher, Senior Design Lab, UC San Diego

January 2018 – June 2018

Planned and executed lab-scale experiments related to chemical engineering processes; for example, calculating the efficiency of a plate heat exchanger, determining the efficiency of a water and ethanol batch distillation tower, controlling the pH of bioreactors, determining the effect of flow rates on the characteristic equations of cooling towers, analyzing the size distribution of liposome nanoparticles using dynamic light scattering (DLS), and determining the rate law of blue methylene dye through UV photocatalysis

Troubleshooted and calibrated equipment such as bioreactor, cooling tower, and batch distillation tower

Analyzed data to determine accuracy and efficiency of fundamental theories regarding chemical and physical processes

Leadership Experience

American Institute of Chemical Engineers, UCSD

Oct 2014– June 2018

Department Chair

oOrganized high attendance events that are meant to facilitate student and faculty networks, promote student and alumni networks, and garner interest in graduate opportunities; increased attendance by 50% of previous year

oResearched and presented on the opportunities in chemical engineering after a Bachelors, specifically for UCSD students

FamilE Head

oMentored and trained less experienced members within the committee and organization

oCreated programs focused on facilitating mentorship and championship within the FamilE
