International Water Expert To Speak In Series Premiere April 25

The University Hygienic Laboratory (UHL) will host Rebecca Calderon, Ph.D., who will present "Monitoring the Microbial Quality of Water: Does it Have to be a Cultural Method?" at noon Wednesday, April 25, in the Oakdale Hall auditorium on the University of Iowa's Oakdale Research Campus.

Calderon, Ph.D., is director of the Environmental Protection Agency Human Studies Division. Her presentation is hosted by UHL's Research and Innovation Committee (RAIC).

"RAIC was created as a means to develop partnerships between UHL and members of the business, science and academic communities," said UHL Interim Director Chris Atchison. "Dr. Calderon's visit is an opportunity for members of these communities, as well as the general public, to join our staff and learn about some of the latest EPA methods."

A graduate of the UI, Calderon went on to receive master's degrees from the University of Rhode Island and the Yale School of Public Health. She earned a doctorate in epidemiology from Yale University. Her presentation is the first in the "Imagine the Possibilities Seminar" series.

"Dr. Calderon is a good fit for the first 'Imagine the Possibilities Seminar,'" said Greg Gray, M.D., UHL scientific advisor and UI professor of epidemiology. "She earned her bachelor's degree in microbiology at the University of Iowa and fondly remembers Iowa City. She is an accomplished epidemiologist and has worked in multiple areas of public health. She especially knows water-quality research and should be able to field questions regarding this dynamic field.

"Dr. Calderon recently has been temporarily assigned to EPA headquarters in Washington, D.C., so she should also be able to tell us about EPA policies and vision," Gray added.

The free presentation is open to the public. No reservations are necessary.

The University Hygienic Laboratory is the state of Iowa's environmental and public health laboratory, with facilities located on the University of Iowa's Oakdale Campus in Iowa City and at the Iowa Lab Facilities in Ankeny, a Des Moines suburb.
