# Wanmei(Cassandra) Kuang > Process Engineer Location: San Bruno, California, United States Profile: https://flows.cv/wanmeicassandra As an ambitious person with curiosity, my career goal is to improve the life quality of people through science and technology and contribute building a sustainable society. I am always looking forward to learning more knowledge and acquiring more skills so that I can be knowledgeable. I am currently looking for a position but not limited to any particular industries because I want to explore and expand my experiences. It will help me determine what I REALLY want to do and enjoy so that I can find my focus for graduate school and future career position. After completing a project for Imerys, I realized that I enjoy being a problem solver and want to be a better one to achieve my career goal. I know I am a problem solver already but the only way to be a better one is to learn more and practice more. Thus, I am actively looking for a new opportunity to explore the world and learn more knowledge and skills. ## Work Experience ### Staff Engineer @ Nkarta, Inc.

I needed to rebuild the Walton filter unit by putting new parts and fittings, made some adjustments on the experimental procedure based on the results of data analysis with MS Excel. The experimental procedure was checked and validated through replicated tests. During the term, I communicated and collaborated with sale representatives, oversea distributors and other scientists, and reported to my supervisor through presentation weekly. At the end of the term, I provided a written Standard Operating Procedure and training to QC technicians after this method was approved and adapted by QC. Although I needed to work overtime for the development stage of the project and during the night shift to run the test method on recent production to meet the needs of customers, I really enjoyed being a valuable problem solver for the company. ### Material Research and Development Intern @ Imerys Filtration Jan 2016 – Jan 2016 | San Jose, California I completed three projects: Carbonation and Calcination of Filter Aids, the Study of Cation Exchange Capacity, and Wine Refining within 12 weeks. Throughout this internship, I got training on a few new analytical instruments through one demonstration and then started working with them independently. During the first projects, I learned and utilized different analytical equipment and methods, including BET surface area, particle size distribution, and loss of ignition. During the second project, I learned the basic knowledge of different minerals and was trained using an analytical equipment, ICP-OES. I executed a series of experiments, analyzed data, and had weekly report presentations with my mentors since the second week of this internship. In addition, I wrote some MS Excel Macro codes for analyzing ICP-OES concentration which significantly increases the efficiency of data analysis. During the last project, I acquired more practices and methods on wine refining such as the Bradford method for protein analysis and thermal treatment for turbidity.
