Jehan Sparks, Ph.D.
“Access isn't the same as understanding. AI can surface past research in seconds, but making sense of the findings still requires critical judgment.”
At Sprig
Jehan is one of Sprig's speakers at Quant UX Con 2026, and a regular voice at Sprig's research leadership dinners and lunches, where she brings a quantitative researcher's view to how AI is changing the field.
She designed a text-message nudge that raised vaccination rates by up to 11% in the largest-ever field experiment on vaccination, covering 47,000 patients, and presented the findings to the White House Covid-19 task force.
She led sentiment tracking surveys for Instagram's advertisers and creators, and quant research on ads products, including GenAI products, for small businesses on Instagram and Facebook.
On Instagram's Communities Labs team, her research identified Flipside as a high-opportunity idea and shaped the main features of its MVP.
Her behavioral science research has appeared in top peer-reviewed journals, including Proceedings of the National Academy of Sciences.
