This is a K25 application for a mentored quantitative research scientist. Much of my research effort this year was focused on developing the preliminary data, and working with my mentoring team which includes: Fernando Martinez, Duane Sherrill, Lynn Gerald, Eric Betterton, Anne Wright, and Andrew Comrie. We have submitted one paper and one abstract. Research: Epidemiological analyses of respiratory outcomes and traffic pollutant exposures. Training: This grant provide training for Dr. Beamer. She has been accepted to the AzCRTP program. I completed 5 courses last year. For this project I will serve as Ms. Sugeng's primary sponsor. The main objectives of this project is to quantify pesticides in farmworker homes, understand how they are getting into the home and what are important characteristics of the pesticides and the homes to assess in future studies. RESEARCH: Ms. Sugeng has collected samples from 21 farmworker homes. They have been analyzed by Battelle Laboratories and we are currently in the process of assessing which factors were most important to their detection in the homes. SERVICE: We collaborated with Campesinos sin Fronteras to recruit participants. Each household will also receive the results of the analyses in their homes. TRAINING: This grant is primarily a training grant for Ms. Sugeng as it is her MS and dissertation work.
