I have studied the relationship between digital technology use (e.g., social media, smartphones) and well-being intensively for the past 5 years, first as a PhD student and now as a postdoctoral scholar. I have developed a specific interest and expertise in the methods used in this area of research, with a particular emphasis on measurement. I have published multiple articles in peer-reviewed journals on the issue of faulty measurement in digital technology research (see References below). Most recently, I was part of an international team of researchers who, after conducting a systematic review and meta-analysis of research in this area, found that self-report measures of digital technology use are highly inaccurate. This work was published last month in the journal Nature Human Behaviour (https://www.nature.com/articles/s41562-021-01117-5) and has received attention from popular outlets like Psychology Today (https://tinyurl.com/pbpd9yf8) and Fast Company (https://tinyurl.com/rvf87ab8).
