Meghan Carey, MS
Degrees: MS in Epidemiology, Drexel University; BS in Biological Sciences, University of Delaware
- Autism risk factors
- Outcomes and quality of life among young adults on the autism spectrum
- Environmental health
- Intentional & unintentional injuries
Focus: My research interests include examining the transition to adulthood and life course outcomes for autistic individuals. For autistic youth, the transition to adulthood can be an incredibly difficult time because as they leave high school they lose access to many services (Roux et al. 2015). I am also interested in understanding environmental risk factors for autism and the association between environmental exposures during pregnancy and autism diagnosis.
Before returning to Drexel, I was working as a Research Coordinator at the Children’s Hospital of Philadelphia. I was responsible for preparing grant proposals, managing project budgets, and securing IRB approval. I’ve drafted major sections of six grant proposals that were funded including two R21s and an R01 from NICHD. I’ve also conducted statistical analyses in SAS, led the development of and served as a co-author on manuscripts, and presented at over a dozen conferences including the APHA annual meeting.
