Where science and tech meet creativity.

Dr. Pamela L. Gay

I am an astronomer, technologist, and creative focused on using new media to engage people in learning and doing science. Join me as we map our Solar System in unprecedented detail through our citizen science projects at CosmoQuest, and learn astronomy through media productions like Astronomy Cast and Escape Velocity Space News.

I am actively seeking speaking engagements and opportunities to collaborate on research related to citizen science, training machine learning algorithms, and science engagement using technology.
