Karen Mejia

Research Coordinator.

Growing up in the Imperial Valley and seeing first hand the disadvantage of some of its residents has given her the drive to work with organizations that aim to improve people’s lives. She’s been involved with community engagement programs beginning in 2012 when she helped create a mobile health clinic to provide screening for those not covered by health insurance.  Now with the AIRE Study she has an opportunity to help bring awareness to children’s health development to both participants and their parents.
