I investigate how human health risks change based on environmental engineering interventions. Questions the drive my research include:
- How can we imvprove the QMRA modeling paradigm and underlying modeling methods?
- How do we optimize drinking water systems to improve health protection?
- How do we make health improvement/protective decisions involving current and new technologies?
- What are the best methods to model intervention health risk protection for decision support?
- What are the One Health / One Water contexts of our societal health risks?
- How do we answer these questions and similiar infectious disease questions in the developing world?
I earned my BS in Environmental Engineering from Wilkes University in 2004, specializing in water treatment and hydraulics. Through international contracting and domestic consulting work I recognized the need to advance the understanding of health protection and cultural appropraitness of engineering technologies. Through this interest I sought out the mentorship of Dr. Charles N. Haas, and in doing so, earned my Ph.D. in Environmental Engineering from Drexel University in 2009. My dissertation was focused on counter bioterror research, particularly and advanced dose response for inahaltion anthrax.
Under Dr. Haas' mentorship I learned risk modeling methods, dose response modeling, and improved my engineering modeling and analysis skills. For my post-doctoral research I sought out Dr. Joan B. Rose at Michigan State University. Here I further developed my risk modeling and health analytics skills. I re-engaged in my first professional passion - water research. Through work with Chuck and Joan, I developed my international reputation in risk modeling and analyses of engineered and natural systems.
