Scholarly Interests
- Water, sanitation, and hygiene (WASH)
- Environmental health microbiology
- Quantitative microbial risk assessment
- Fecal waste streams for public health surveillance
- Enteric pathogens
- Antimicrobial resistance
Using tools from engineering, epidemiology, and environmental microbiology we investigate the problems affecting low-income individuals and aim to improve public health in the communities where these people live. Our research focuses on the three pillars of public health engineering:
- Public health surveillance using fecal waste streams;
- Assessing the fate and transport of fecal contamination in the environment;
- Predicting public health outcomes using quantitative microbial risk assessment.
Drew's research focuses on communities that are on the margins of society - in the US and internationally - where water and sanitation infrastructure is inadequate. He has broad interests in the field of water, sanitation, and hygiene (WASH), environmental microbiology, microbial risk assessment, enteric pathogen fate and transport, and evaluating interventions to interrupt the transmission of infectious diseases.
Projects
- Evaluation of a World Bank funded sanitation intervention in Quelimane, Mozambique
- Infection risks associated with flies in communities with inadequate sanitation
