This study examined more than 2,000 adolescents to explore how habitual smartphone use affects attention. While frequent habitual use predicted poorer attention regulation, smartphones also fulfilled psychological needs for competence, autonomy, and relatedness, which partially protected against these effects, suggesting that how adolescents use smartphones matters as much as how often.

This research examines why undergraduate engineering students struggle with troubleshooting technical problems. By observing electrical engineering students fixing broken circuits, he aims to identify where they get stuck, compare their approaches with expert strategies, and develop classroom exercises that build practical troubleshooting skills for labs, projects and real-world engineering work.
