Dr. Guevara, a founding member of PolicyLab: Center to Bridge Research, Practice, and Policy, has research and clinical interests at the intersection of early child development, behavior, and health disparities. He has partnered with community-based organizations, government agencies, and parent advocacy groups to address policy-relevant questions aimed at reducing inequities in early childhood development and behaviors. He has sought through his research to test psychosocial interventions to provide parents with the resources and tools to improve the care of their children and reduce disparities.

His notable career accomplishments to date include:

· The Translating Evidence-Based Developmental Screening Study, which found that those children who received screening with a validated tool were more likely to be identified with a delay, referred to early intervention, and be eligible for services than children who received routine developmental surveillance.

· The ADHD Link Study, a comparative effectiveness trial of care management that suggests that children who receive care management had improved ADHD symptoms compared to usual care.

· The Parenting for Depression Study, which consisted of 2 studies assessing coaching for mothers with depressive symptoms. In the first study, women with depressive symptoms participated in a randomized waitlist trial of in-person coaching but results showed no benefit and few women completed the program. In a second study, mothers with postpartum depressive symptoms were randomized to receive a social media-based versus in-person group parenting intervention. Attendance was significantly higher in the social media group, and women reported improved depressive symptoms and parenting self-efficacy in the social media group.

The Faculty Diversity Study, which suggested that minority faculty representation is slowly increasing but that minority faculty development programs at allopathic medical schools did not improve this representation. However, the Harold Amos Medical Faculty Development Program, a national program of the Robert Wood Johnson Foundation, was successful at facilitating leadership positions for minority faculty.
