Parra-Cardona says that receiving this grant allowed him to focus his research on parenting with Latino populations. He was able to establish a federally funded program with grants from the National Institute of Mental Health and National Institute On Drug Abuse to conduct research with underserved Latino populations. His clinical experience has included the provision of services to street children engaged in drug trafficking and prostitution, victims of sexual abuse and violence, adolescents involved in the juvenile justice system, and adult federal probationers convicted for drug trafficking.
