What I'm looking for

I seek a collaborative environment where I can leverage my UX research skills to enhance user experiences and drive product innovation.

As a UX Research Lead at Cotality, I spearhead multi-method research initiatives that have uncovered critical usability issues impacting significant revenue streams. My work involves collaborating closely with designers and product managers to deliver actionable insights and prioritize redesign directions. I have successfully facilitated workshops and stakeholder interviews, ensuring alignment on product goals and strategies.

Previously, I contributed to UX research for WebMD, where I focused on enhancing user engagement and navigation flow. My efforts resulted in a redesigned prototype that significantly reduced drop-off rates. With a strong foundation in Human-Computer Interaction and Design from UC Irvine, I am passionate about creating user-centered solutions that drive business success.
