The driving force behind my research is the control of waterborne disease
transmission from both watershed protection and drinking water treatment perspectives.
Slow sand filtration is a water treatment option attractive for rural
communities and developing countries because it is reliable, affordable, and
requires minimal maintenance. However, each filter run requires a ripening
period during which filter effluent must be either wasted or recycled back
for refiltration until the filter produces water that meets drinking water
standards. I am interested in making slow sand filtration more efficient,
economical, and practical by using non-traditional media and media modifiers
to enhance filter ripening and delay the onset of filter clogging.
Control of waterborne disease through a better understanding of pathogen
ecology is a related research interest. Cryptosporidium parvum
is a human and animal parasite responsible for an acute gastrointestinal disease
that is self-limiting for otherwise healthy people but prolonged and life-threatening
for the immunocompromised population. Cryptosporidium spp. oocysts
are a challenge to remove from drinking water supplies because they are resistant
to chlorine disinfection and too small to effectively filter. I have
completed lengthy environmental studies tracking Cryptosporidium spp.
oocysts in the Wachusett Reservoir watershed in central Massachusetts (the
drinking water source for Boston and surrounding municipalities) to identify
sources and species of Cryptosporidium oocysts as well as any seasonal
trends associated with Cryptosporidium spp. presence. I have
shown that multiple species and genotypes of Cryptosporidium are present
in the watershed, and because not all species cause disease in humans, this
finding supports the need for species-specific detection methods to assess
the potential health risks of Cryptosporidium spp. presence in the
environment. In addition, my work has shown that geese are an important
source of Cryptosporidium spp. oocysts, particularly in agricultural
areas. I have identified novel 18S rRNA genotypes of Cryptosporidium
spp. in geese, revealing more extensive parasite diversity in the environment
than was initially reported. The goal of my work is to provide a greater
understanding of the environmental behavior of Cryptosporidium spp.
oocysts so that watershed management can minimize public exposure to this

In summer 2005, I travelled to Pueblo Nuevo, Honduras to assess a potential
Lehigh University project to improve the water supply and sanitation systems
for this rural village. Meetings with the local doctor, educational leaders,
and the town mayor identified a need and a desire on the part of the local
community to work with Lehigh University students on designing and implementing
these improvements. In Fall 2005, we started a Lehigh University Chapter
of Engineers Without Borders-USA within the broader Lehigh University student
organization Students for Sustainable Development (check
out our website) . Our goal is to work in multi-disciplinary teams to
provide a safe drinking water supply for the community of Pueblo Nuevo.

SummerCHOICES (Charting Horizons and Opportunities in Careers in Engineering
and Science) is an engineering summer camp for middle school girls. I lead
a hands-on environmental engineering project in which students learn about
the global importance of safe water and sanitation and the processes involved
in drinking water treatment, and then create drinking water from muddy water
by applying their knowlege in the laboratory. This project has been fun
and eye-opening for the students who have participated! For more information
on the summer camp, visit the SummerCHOICES
website or read the article published about SummerCHOICES 2004 in Lehigh
