Most notably, he worked with the 2007 and 2013 National Roadside Surveys examining the roles alcohol and drug use has on adverse motor vehicle outcomes. He also developed and validated a measure based on data available from these large national data sets. Additionally, he worked as an analyst on numerous studies examining the effectiveness of alcohol-related laws and regulations on adverse driving outcomes. He has authored numerous journal articles and presented at national conferences on his work many times.
