05 Statement of Intent​

I applied to UT Austin Master’s degree in order to achieve two goals. One is that improving skills both UX research and UX design. Another goal is learning new technology trends and techniques for research or design.


Before I came to UT Austin, I worked five and half years as UX designer at Samsung Techwin, where I implemented and managed diverse types of projects with delivering UI/GUI for packaged software, industrial device, web, and mobile application. Throughout these projects, I had in-depth experience on applying different UX research methods to various domains under a fast iterating work process. In addition, working closely with developers, marketers, product managers, and business stakeholders helped developing smooth communication skills with people outside my expertise. Furthermore, I have developed 9 patents on security camera UI features where 4 of them are international patents. 


During my graduate studies and a recent internship, I have participated in diverse UX research and design projects. For example, I conducted UX research to propose design recommendations for the Texas Commission on Environmental Quality website, which receives more than 135,700 page views a month. In an Interaction Design course, I designed an eco-friendly game application as a team leader using Adobe XD through UX research and usability testing. Surveys and interviews were conducted to reify the project goal. Through conducting multiple usability tests, I could enhance my understanding on how to achieve users’ needs. In a Human-Computer Interaction course, I created a conceptual prototype using InVision to redesign the Capmetro mobile application based on UX research and analysis.


When I encounter new technologies and capabilities, I welcome the opportunity to gain new insights on solving problems. For example, while taking a Rapid Prototyping & Lean UX Methodologies course, I conducted AR/VR technology research to design a museum exhibition. In another course, I investigated IoT research and proposed a smart home application as a type of lo-fi prototype. I also studied how reviews of e-commerce sites influence customers’ decisionmaking and designed an eye-tracking experiment. I analyzed results from the experiment and wrote a research paper, which I presented at our school’s Open House with a prototype video and a poster. 


In Conclusion, I improved UX research and design skill during MSIS degree. Also, I learned a lot new skills such as Google Analytics, Google Tags, OptimalWorkshop, eye-tracking experiment, 3D printing (Blender, Cura), Sketch, Adobe After Effect/ Premier/ XD, InVision, Axure, and database management (SQL, my PHP).
