Their paper, Platform Design Change and User Engagement: A Natural Experiment on Twitter was initially shortlisted for both the AoM's Technology and Innovation Management (TIM) Division Best Paper Award and the TIM Division Best Student Paper Award. It was ultimately selected for the AoM's Best Paper Finalist honour.

The paper investigates the impact of platform design changes on user engagement. The study reveals that increasing the character limit on Twitter enhances user engagement, including likes, replies, and retweets. This effect is notably stronger for users with large follower networks and those producing novel content.

Reviewers at the conference commended the paper for its comprehensive approach to platform governance, extending beyond network size to consider user and content characteristics. 'The research offers valuable insights from both scientific and practical perspectives within a leading social media platform'.
