I am a computer scientist, researcher, and interaction designer. I currently work as a Senior Research Programmer/Analyst (will be a Project Scientist from December 2018) in the CREATE Lab in the Robotics Institute at Carnegie Mellon University. My research focuses on designing, implementing, and evaluating interactive systems that support community engagement and democratize scientific knowledge. Techniques that I apply include:

  • Citizen Science/Civic Engagement
    to empower lay people and professionals to establish sustainable partnerships and produce impactful scientific knowledge.
  • Crowdsourcing/Participatory Sensing
    to engage diverse community members in collecting high-quality data over large geographical areas and long periods of time.
  • Interactive Data Visualization/Storytelling
    to enable communities to explore the collected data, identify patterns, form hypotheses, and raise public awareness by sharing findings.
  • Machine learning/Computer Vision/Artificial Intelligence
    to assist communities in organizing scientific knowledge and interpreting patterns in large datasets.

In general, citizen science empowers amateurs and professionals to form partnerships and produce scientific knowledge. For example, the US Environmental Protection Agency has adopted citizen science to engage the public in environmental protection (as shown here in detail). The US National Institutes of Health also uses citizen science to address environmental health concerns among communities (as shown here in detail). Moreover, the US federal government envisions citizen science as a strategy to promote public engagement in tackling critical real-world issues (as shown here in detail). For more information about the framing of citizen science, please refer to the introduction chapter in my Ph.D. thesis documentation and presentation video.

I received my Ph.D. degree in Robotics in 2018 from the Robotics Institute at Carnegie Mellon University (CMU). Previously, I received my Master's degree in tangible interaction design in 2012 from the School of Architecture at CMU, where I studied and built prototypes of interactive robots and wearable devices. Prior to CMU, I earned dual Bachelor's degree in both architecture and computer science in 2010 at National Cheng Kung University, Taiwan.
