Zaijing Liu / UX Research
About

I’m a mixed-methods UX researcher with a background in human factors and computer science. I’m currently pursuing my master’s degree in Human Factors/Ergonomics at San Jose State University, where I also work as a research assistant in the BAT Lab.

What I enjoy most about research is understanding why people behave the way they do when interacting with a system. I combine qualitative methods, such as usability testing, interviews, and behavioral observation, with quantitative measures to understand both what users do and why they do it. My experience ranges from wearable haptic interfaces for automated driving to usability research for mobile and web products.

I’m especially drawn to research that goes beyond identifying problems and helps turn user behavior, needs, and data into practical design decisions.

My Journey

Originally from China, I moved to the U.S. in 2020 to begin my studies. I studied Computer Science as an undergraduate at San Francisco State University, and although I already knew about UX Research at the time, most of my UX-related coursework focused more on design. I chose Design as a minor because I wanted to strengthen my design thinking and learn how to communicate ideas more clearly through visual storytelling and presentation.

When I started graduate school in Human Factors/Ergonomics at San Jose State University, I joined a Human Factors research lab during my first semester and began taking courses focused on UX Research. The two experiences complemented each other in different ways. In the lab, I learned what it actually takes to run a research study—from experiment design and data collection to analysis. My coursework helped me understand different research methods, the reasoning behind study design, and how to choose the right method for a specific research question.

As I became involved in more projects, I realized how much I enjoyed the research process itself. My Computer Science background also became surprisingly useful. I’m comfortable working with data, writing code when needed, and picking up new tools quickly, which allows me to bring a more technical perspective into my research.

Coursework first sparked my interest in UX Research, but my lab experience confirmed that it was the career I wanted to pursue.

Why UX Research?

Research feels a lot like solving a puzzle to me. You start with an observation, form hypotheses, collect evidence, look for patterns, and gradually build a clearer understanding of what is really happening.

I especially enjoy connecting seemingly scattered pieces of information into an evidence-based story that helps a team understand what users are experiencing, why it is happening, and what we can do about it.

That combination of analytical thinking and human-centered problem solving is what keeps me excited about UX Research—and why I see it as the direction I want to continue growing in.

Outside of UX

Outside of UX, I enjoy cosplay, which has become another way for me to keep learning and creating. Through cosplay, I’ve picked up skills like wig styling, prop making, video editing, and makeup. I also tend to hold myself to a high standard—even when something can’t be perfect, I still want to give it my best effort.

I’m also someone who values planning and time management. I believe that a well-planned day helps me move closer to the life I want to build.

And this is Baozi, my little tabby cat. He’s incredibly affectionate, loves being around people, and is usually nearby whenever I’m working or taking a break.
