SWEET Lab

Social Well-being, Empathy, and Emerging Technologies Lab

Lab Mission

Our lab is dedicated to advancing human well-being and flourishing in the digital age. We investigate how digital technologies mediate and affect well-being and social relationships, and we design technologies to promote social connection, empathy, and mental health. Our team is dedicated to understanding the socio-emotional impact of emerging technology and develop responsible, human-centered AI systems that prioritize user safety and well-being.

[We’re hiring!] Our lab is recruiting PhD students and research assistants (in person and remote). Please email Dr. Renwen Zhang (renwen.zhang@ntu.edu.sg) if you are interested.

Lab Projects (Selected)

Human-AI Relationships and Communication

This project explores the motivations, processes, and outcomes of engagement with AI chatbots, with a particular focus on self-disclosure, trust, and relationship development. Our studies will contribute to the theory-building of human-machine communication and inform the design of social chatbots that are empowering and beneficial to users. Through this exploration, we seek to establish guidelines and best practices to foster meaningful, beneficial, and harmonious relationships between humans and machines, shaping a future where technology truly complements the human experience.

AI-Mediated Empathetic Communication

This project dives deep into the realm of AI-mediated supportive communication, exploring how AI can be harnessed to enhance and facilitate empathetic exchanges. We investigate the ways in which AI tools can craft messages that resonate with human emotions, while also assessing the effectiveness and authenticity of such interactions. By analyzing the nuances of AI-generated content, our goal is to refine and optimize the blend of technology and human touch. This research strives to pave the way for a future where AI not only communicates but genuinely supports, enriching human connections in an increasingly digital age.

Responsible AI and AI Ethics

This line of work examines the socio-emotional harms of AI systems—harms that are often implicit, context-dependent, and gradual. We study how these harms emerge, evolve, and shape people’s emotions, relationships, and well-being over time. By developing deeper theoretical and empirical insights into how AI influences users on a relational and emotional level, our goal is to inform the responsible and human-centered design, evaluation, and governance of AI systems, especially those that interact with people in intimate or emotional contexts.

Digital Well-Being

This project delves into the intersection of technology and personal well-being, exploring how digital platforms and tools influence our mental, emotional, and physical wellness. We aim to understand the positive and negative implications of increasing digital interactions. Our findings will guide the development of recommendations and strategies to promote healthier digital habits, fostering a more balanced and mindful tech-integrated lifestyle. Embracing the future of digital wellness, our research will empower individuals to harness technology for holistic well-being.
