Tammy has been studying how people use the internet since the olden days, when being able to center text was a big deal and you could have any color of website you wanted (as long as that color was grey). Her 20-year research journey into the heart of UX began when she rigged out her first usability test lab with a state-of-the-art Power Mac 9500. Since then, she’s also done some pretty far-out studies involving EEG headsets and facial action coding.
Her book, Time Is Money: The Business Value of Web Performance, was published by O’Reilly Media in 2016. She co-curates (with Tim Kadlec) WPO Stats, a collection of case studies and experiments demonstrating the impact of web performance optimization on user experience and business metrics.
