Jose Arellano Martorellet
Welcome! I am a PhD candidate in Behavioral Decision Research in the Department of Social and Decision Sciences at Carnegie Mellon University, advised by Gretchen B. Chapman and Silvia Saccardo.
I'm drawn to behavioral research that can inform policy. My work uses field and online experiments, along with administrative data, to examine how people engage with information, form judgments and make decisions, particularly in health.
Before my doctoral studies, I worked extensively on applied research and behavioral interventions with public and private organizations in Peru and across Latin America.
Questions that drive my work
Attention and engagement
- Why do people avoid health information that could help them?
- Can redesigning routine patient notifications get more people to engage with their care?
Credibility and beliefs
- What makes a health communicator look like an expert?
- Why do some social norm messages persuade while others fall flat?
- How can trust in scientists be strengthened?
From intention to action
- What helps patients and physicians close gaps in preventive care?
- Can low-cost, behaviorally informed programs change everyday parenting practices?
