Research Repository Design

From centralized storage to AI-powered insights—scaling research impact across Sound Transit.

Summary

As the sole UX designer, I conducted research and led the design of the organization's first research repository. I collaborated with researchers, engineers, and librarians, to align on product objectives. By leading co-create workshops with stakeholders, I conducted rapid iteration and ensure that designs balance user needs with business objectives and technical feasibility. Finally, I showcased the product roadmap with strong storytelling, laying foundation for the short and long term implementation.

Problem

The organization lacked a centralized way of organizing research data, resulting in excessive communication cost and low efficiency.

Outcome

I established the organization's first research repository, housing all research data and increasing reusability of research data by 70%.

Research

During the agency’s rapid expansion, centralizing research data became a critical organization-wide need

To gain context of the problem space and user's perspective, I initiated meetings with the researchers, engineers, and document librarians to understand the existing experience with communicating and storing research data. Through which I identified the following key insights:

1

Data silos and poor cross-functional access

"I can't find the research insights that (external team) is requesting!"

2

Need of flexible organization based on research document type

"I need to present my findings differently every time."

3

Struggle to connect with previous research or find related documents  

"I remember doing this research before, but I don't know which ..."

I visualized the current user flow of communicating research data to external teams

Problem statement

How might we centralize research data to improve accessibility of rider insights and enhance cross-agency collaboration?

Design objectives

Maximize information utilization between cross-functional teams

Centralize all distinct research projects in one place

Support continuous discovery of recurrent themes across research projects

Reduce disposable insights and maximize impact of research data

Co-create Workshop

First step of building consensus is gaining clarity

I organized 1 round of brainstorming and 2 rounds of card sorting workshop to clarify how researchers perceive data organization. Through which I uncovered the following critical insights:

1

Researchers sort themes differently based on their personal engagement with projects

2

Multiple themes often apply to the same research data

3

Researchers lack understanding on each other's individual projects

Testing and iteration

Creation of the agency's first taxonomy—shared language used across the agency

I approached the development of a shared taxonomy as an iterative process, requiring multiple rounds of refinement. First, I organized an internal review to gather feedback and align on structure. Then, I conducted a second round of prototype testing to validate real use cases through the SharePoint implementation.

Internal review of taxonomy structure

I facilitated the internal review so that researchers were able to gain consensus on the overall structure and resolve conflicting opinions.

Prototype testing of real use cases

Researchers experience the use case of the shared taxonomy and metadata by each uploading 3 representative works of their choice on to the repository.

I prototyped the research repository with the Sharepoint library and created the founding metadata library used by the research team

Key iterations

Expand structure and terms in taxonomy

Based on feedback, I broadened the taxonomy to include additional categories and terms, ensuring it could flexibly capture a wider range of research projects

Research ownership clarification

I added distinctions between internal and external research roles, making it easier to identify ownership and improve accountability in documentation

Research topic theme brainstorming and organization

I facilitated workshops to brainstorm and group themes, creating a more intuitive structure that supports easier navigation and knowledge sharing

Roadmap

Laying strong foundation for an iterative roadmap

I laid the foundation for the agency’s first research repository by mapping out a clear short-, mid-, and long-term development roadmap. This staged approach not only delivered immediate efficiency gains but also positioned the repository as a scalable, future-ready knowledge hub for Sound Transit.

I presented a new workflow for internal communication by leveraging the research repository

Impact

Accelerate information sharing of transit research that impact millions!

Presenting my projects to 50+ employees at the agency was a rewarding experience!

Accelerated Discovery

Centralized storage and metadata helps researchers find relevant documents faster and discover non-obvious connections between different research topics

Consistent Organization

Shared taxonomy system ensures consistent tagging across disciplines while maintaining flexibility for domain-specific needs

Streamlined Onboarding

New team members can quickly navigate and understand the research landscape through clear document organization

Learnings

Be curious, collaborative, and creative!

The amazing research and innovation team that I get to spend time with throughout the summer!

Proactivity drives impact

Reaching out for 20+ coffee chats taught me that meaningful change starts with taking initiative to listen, connect, and build trust

Curiosity is the fastest way of learning

Asking questions and seeking mentors beyond the agency reminded me that curiosity not only accelerates learning but also opens doors I didn’t know existed

Intuitiveness is the ultimate shared language

I realized that when a design feels effortless to use, it bridges backgrounds, roles, and expertise better than any explanation I could give

Transit Art Program Webpage Redesign

Summary

I led the redesign of the web and mobile site for Sound Transit's art program to boost digital presence and engagement of all artworks along the entire Puget Sound transit system. I reconstructed the information architecture, increased navigation accessibility, and introduced new subpages. I worked with the content editorial team to ensure content viability across all artwork types, and delivered detailed design specs for seamless engineering implementation. The redesigns will be shipped in S3!

Problem

Over the last 2 years, the art program experienced decreased engagement in website navigation time, active users, and views.

Outcome

I shipped redesigns of the STart page, created the Artwork Gallery and Interactive Map feature, which improved the information architecture and site engagement rate.

What is the STart program?

The STart program engages local artistry with everyday transit experience.

User Goals

I want to learn about the artworks and artists featured along the transit system. Also, understand how one can participate in the program.

Business Goals

We want to Increase audience engagement with the art program, promote the digital resource, and boost user view and session time on the official website.

How much do you know about the art that you pass by everyday?

Statistics showed that the art page isn’t reaching or retaining users…

After the redesign kick off meeting with the digital team, I utilized Google Analytics to identify key metrics that showcased the current site's performance.

-65.04%

Average engagement time/active user

0.03% 

of total site active users

<0.01% 

of total site views

Problem statement

How might we increase user interaction with the STart program through an improved digital experience?

Research

Users find it hard to engage with the art program both physically and digitally

I conducted field studies and semi-structured interviews along 10 stations, experiencing first hand on users pain points with low engagement and low discoverability of the art program information.

👀

"Wait, so what is this artwork about…?"
Low visibility of on-site artwork information rarely catches the audience’s attention.

"I didn't know this website exists…"
Audiences expressed curiosity about the artworks but were unaware of the dedicated web page​.

Usability testing

The current webpage is overly dense and challenging to navigate

I conducted usability testing with 3 potential target audiences—a novice user, a general audience, and a potential artist. Revealing the key usability issues of the current website.

Low discoverability on important features

Critical information such as artwork gallery and news subscription are scattered in the side bar, making it hard to discover for novice users.

Unclear navigation for distinct target audiences

Resources for artists and general audiences are combined in the document section, making it difficult to find essential information.

Conflicting and dense writing contents

The site appears to be very text heavy, which includes repetitive CTAs and unrelated descriptions such as the file size and update date.

Final design

The new homepage experience

Program overview

A new layout of the art program overview with 3 dedicated sections and CTA of the main features: Artwork gallery, Public art map, Open calls—offering a quick, at-a-glance summary for users.
