Teaching (Old and New)

In the past I’ve taught a few years of a Public Health-focused GIS course at Berkeley.  And since 2006, I’ve taught a graduate-level course on Health Impact Assessment with Rajiv Bhatia.  I’ve also co-taught the MPH-breadth course, Introduction to Environmental Health with Kirk Smith, and even an accelerated online version of the course.  I was teaching both semesters, 9 months out of the year.

Because UW is on a quarter system, my required teaching load is less, and there are already existing courses in some of the previous topics that I’ve taught, I have some flexibility in teaching in new areas.  To get a feel for the quarter system and teaching at UW in general, I’ll be co-teaching with Chris Simpson, ENVH 555 Instrumental Methods for Industrial Hygiene Measurement: Laboratory.  I’m also planning to contribute some lectures and time to Andy Dannenberg’s HIA course, ENVH 536/URBDP536: Health Impact Assessment.

Moving forward, I’ll probably introduce a couple new courses of my own.  The first in the fall will likely be a GIS course that makes use of the excellent computer teaching facilities within the school.  As usual for my courses, there will be strong practical element to the assignments, and projects that allow students to learn-by-doing and by interacting with other students in teams.

A quantitative microbial risk assessment of water reuse for California’s agricultural irrigation

The current drought in California highlights how precious a resource water is to the lives of California residents, the state’s natural ecosystems, and its agricultural economy. Over the last few decades, recycled water — the reuse of treated wastewater — has played an important role in meeting ever increasing demands for water.  Since the early days of water reuse, questions concerning the safety to public health have been raised numerous times.  And, the practice of quantitative microbial risk assessment has responded by evaluating the efficacy of treatment processes on the removal of infectious agents in wastewater, and by assessing quantitatively using risk models, the potential for water reuse to result in infection and disease in human populations through various exposure scenarios.

I was involved in the quantitative microbial risk assessment (QMRA) modeling for a recent review of water reuse for California’s agricultural irrigation.  The QMRA was part of a process that involved input from a panel of experts, who addressed a number of issues relevant to developing assumptions for the QMRA, as well as relevant to the interpretation of the QMRA’s findings.  The panel and QMRA were commissioned by the California Department of Public Health, which recognized the need to reassess risks given the potential for increasing water reuse in agricultural irrigation, improved knowledge of the concentrations of microbial pathogens found in wastewater, and new treatment processes.  The report of the findings from this process is available here.
