UX research leader · Human-Computer Interaction

Technology serves people best when they participate in its design.

For more than 10 years I've built and led UX research programs across consumer technology, telecommunications, healthcare and emerging tech. My work pairs behavioral data with qualitative depth, puts accessibility at the center of product decisions, and uses AI to make research faster without making it sloppier.

Making personalized offers easier to act on

Why were customers bouncing off offers that were built for them?

In short My synthesis of Verizon's offer research shaped a tile redesign, and the design changes contributed to a 25% increase in offer acceptance.

Context

Verizon was introducing multi-offer tiles to bring personalized offers together across the My Verizon app and website, and offer engagement had declined.

Approach

I paired behavioral telemetry with in-depth interviews, then synthesized findings across several offer studies, including a color study and tile usability testing run by my team. The data showed where people dropped off. The interviews explained why: problems with visual hierarchy, color and typography, including brand color combinations that added friction.

What changed

The synthesis became a set of experience principles for offer strategy, and design used it to rework tile layout, color and placement. Those design changes contributed to a 25% increase in offer acceptance.

Choosing a line or device inside a chat

What selection pattern helps people pick the right line or device in Verizon Assistant, on a phone screen?

In short A 193-person test showed vertical lists were 10 seconds faster than carousels, and led to a recommended standard for choosing a line in chat.

Context

Verizon Assistant had no standard template for choosing a line or device in chat. The goal was to find the layout, controls and level of detail that worked best and turn them into a standard.

Approach

I ran unmoderated interaction tests with 193 participants, comparing vertical layouts with carousels, different selection controls, and levels of information density up to Level 4: name, number, device image, plan details and pricing.

What changed

Vertical layouts beat carousels on speed, and the most detailed rows gave people the most confidence. The findings led to a recommendation to standardize vertical layouts on mobile across plan management flows, and a baseline rule requiring a device image for every troubleshooting line selection. People preferred confirming a selection because it prevented mistakes, and the pattern with radio buttons and a confirm step scored 58% confidence and 41% ease of use.

Finding the traps in a mobile checkout

Could people using assistive technology actually buy a phone in the reskinned mobile sales flow?

In short Assistive technology users failed 30% of purchase tasks. I traced the failures to four causes, and every fix I recommended was remediated.

Context

Verizon's Next Gen Digital mobile sales flow was being reskinned under the new Monarch brand. The study checked whether people using assistive technology could still complete a purchase.

Approach

I ran an unmoderated study with 27 assistive technology users, 10 prospects and 17 existing customers, on desktop and mobile. They included 16 screen reader users, 5 switch and voice control users, and 6 low-vision magnification users, each working through purchase tasks.

Findings

  • Sign-in loops that sent authenticated customers back to the login screen
  • A focus trap in the Estimated Next Bill modal
  • Unlabeled trade-in and porting options that a screen reader announced as "Object Object"
  • Visual density that went beyond what participants could comfortably take in

What changed

I turned the findings into prioritized fixes for engineering and design: stop authenticated sessions from resetting, remove the focus trap in the bill review dialog, add programmatic labels to radio buttons, and move dense specs into collapsible sections. Each fix was logged as a Jira ticket and remediated, clearing the blockers from checkout steps where high-intent customers had been dropping out.

Why teams detach from the design system

Why were product teams detaching from standard Verizon Design System (VDS) components, and what would make the system easier to adopt?

In short Teams using the design system worked up to 5 times faster. I found the 10 components teams abandon most, and why.

Context

Product teams were detaching from components in the VDS central library and building their own. This study was part of VDS Promise, a research program testing whether the system delivers on consistency, inclusivity, and speed and efficiency.

Approach

I configured an AI design audit tool to analyze component analytics and find the 10 components with the highest detachment rates. I then interviewed 13 designers and developers on live product teams about adoption, workflow speed and the friction of integrating the system into their work.

Findings

  • Teams using VDS components worked up to 5 times faster than teams building custom ones, saved about 25% of redesign time, shortened development cycles by more than a month, and got pre-vetted accessibility compliance
  • A web-first engineering bias with outdated viewports that didn't support mobile-first layouts
  • A rigid atomic structure that lacked complex, ready-made components
  • Poor discoverability, and error-prone transitions between versions

What changed

The audit isolated specific gaps in the system and informed updates to the central library. The adoption study led to four recommendations: make VDS usage part of leadership acceptance criteria, set aside sprint time for visual quality defects, expand Figma and front-end coding training, and open contribution paths so teams can add to the system instead of relying on a central team alone. The VDS Promise research also shaped roadmap items, including a Figma bulk-updating plugin, low-fidelity wireframe libraries and motion packs.

Creative tools for people of all abilities

How do gesture, sight and sound work as inputs for making art and music, for people with diverse physical, sensory and cognitive abilities?

In short User research for a set of accessible creative tools that won the 2019 Cannes Lions Design Grand Prix.

Context

Creatability is an open-source set of experiments that use machine learning to make creative tools more accessible, built by Google Creative Lab with NYU's Ability Project.

Approach

I ran user research with people with diverse abilities and tested new interaction modes as they were built, working across research, design and engineering.

What changed

Research findings guided the design of the tools. The project went on to win the 2019 Cannes Lions Design Grand Prix.

Choosing the method for the question

Conjoint showed people liked each feature of a purchase flow on its own. Usability testing showed they got lost when the features were combined. I pick methods by the evidence a decision needs, like using diary studies over interviews to see how people with disabilities fit connected devices into daily routines.

Growing researchers

I managed and coached a team of six early-career rapid researchers on study design, synthesis and holding up under stakeholder questions. Four moved into senior roles.

Raising the bar on rigor

I partnered with Verizon's Insights Center of Excellence on standards for sample size, data quality and representation, and wrote the team's internal accessibility guidelines for surveys and vendors.

Moving faster with AI

I lead the design and validation of the team's AI research tools, including a searchable repository of 1,043 research studies, synthetic user testing and an automated readability crawler for verizon.com. I also co-led an AI tree-testing platform that compares how different AI agents navigate a site.

Accessibility beyond the product

I led the Insights Association's 2025 research initiative on disability identity, ran a workshop and certification at TMRE, presented at the CRC, and helped the Accessible Insights Consortium double its membership. I also mentored two American Foundation for the Blind interns on a study of AI assistants and assistive technology.

Telling the story

Research only matters when it changes a decision. I write memos, readouts and executive presentations that make findings simple enough to act on.
