Rolf Halden, Ph.D., P.E., is associate director of the Swette Center
for Environmental Biotechnology at the Biodesign Institute, professor
in the Ira A. Fulton School for Sustainable Engineering and the Built
Environment, interim co-director of the Center for Health Information
& Research, and senior sustainability scientist for the Global
Institute of Sustainability at Arizona State University.
Halden is a noted expert in determining where in the environment
mass-produced chemicals wind up, their impact on health, and how to
remove them from contaminated water resources, aquifers and
agricultural soils. Toxins of interest include dioxins, anti-bacterial
products, pharmaceuticals and personal care products (PPCPs),
organohalides, problematic plastics and their additives, as well as
pesticides – all having potential health impacts, including
adverse birth outcomes, inflammation and increased risk of cancer.
In his research, Halden detected antimicrobial additives of personal
care products, used as far back as the 1960s, to persist to this day
in estuarine sediments along the East Coast. In 2004, his team first
discovered triclocarban as a pollutant of the U.S. environment
nationwide. Halden’s research on antimicrobials and his
briefings to the Environmental Protection Agency helped to prompt a
review of the antimicrobial triclosan by the agency 10 years earlier
than planned.
An inventor, Halden has developed several patented and
patent-pending technologies to monitor toxins in groundwater and to
determine the best way of removing them from precious drinking water
resources by using naturally occurring microorganisms. One invention,
the In Situ Microcosm Array (ISMA) device, is a self-contained, field
deployable lab-to-go, suitable for conducting multiple sediment column
experiments simultaneously in the subsurface.
In addition to toxins in wastewater, Halden’s team
is researching the emission of toxic dioxin into U.S. air from
incineration of triclosan-laden municipal sludge, or biosolids, and,
in a related study, completed the first whole-genome sequencing of a
naturally occurring bacterium uniquely capable of using toxic dioxins
as a food source.
While investigating the burden of toxic chemicals in the
human body, Halden and collaborators completed a global assessment of
contaminants and proteins detectable in umbilical cord blood to better
understand the fetal health risks from in utero exposures to tobacco
constituents from maternal smoking and to other environmental toxins.
This work yielded the first map of hundreds of proteins detectable in
human cord blood and singled out more than a dozen interesting
biomarker candidates of toxic exposures and effect.
Halden’s research found common pesticides in cord blood,
suggesting that pregnant women receive regular, chronic exposures,
which may perturb fetal development. He is part of an ASU team
studying the potential health risks of engineered nanomaterials in
water, food, commercial products and biological samples.
Prior to his work at ASU, Halden was at the Johns Hopkins Bloomberg
School of Public Health in Baltimore, MD, where he served as a
co-founding member of the Center for Water and Health. He maintains an
adjunct faculty appointment at Hopkins in the Department of
Environment Health Sciences. Prior to joining academia, Halden was a
project engineer at the Lawrence Livermore National Laboratory, where
he directed the construction and operation of physical and biological
groundwater treatment systems.
In 2010, Halden edited a book for the American Chemical Society (ACS)
entitled “Contaminants of Emerging Concern: Ecotoxicological
and Human Health Considerations,” published by Oxford
University Press. He has authored 80 peer-reviewed articles, 11
book chapters, 15 patent applications, 130 conference papers, and
presented over 100 invited lectures and keynote addresses at
national and international scientific symposia. Halden is a special
government employee who provides expert advice to several
governmental agencies, the National Research Council and the
FDA’s Nonprescription Drugs Advisory Committee.
Halden received master’s and doctoral degrees in civil
engineering (with a concentration in environmental engineering) from
the University of Minnesota and a master’s in biology from the
Technical University of Braunschweig, Germany. He is registered as a
professional environmental engineer (PE) in Minnesota and Arizona.

[VISIT THE HALDEN LAB]
Dr. Halden's research explores the connection between anthropogenic
activities, environmental quality and human health. His research
relies heavily on the use of mass spectrometric tools (e.g., LC-MS/MS,
MALDI-TOF) for applications in environmental proteomics,
bioremediation and public health engineering. Ongoing projects focus on:
Bioremediation of Environmental Contaminants
We are conducting research and
also are supporting full-scale field deployments of bioremediation
strategies for the removal of toxic pollutants from impacted soil
and groundwater environments. This work includes the development of
novel diagnostic devices for groundwater monitoring and remedial design.
Pharmaceuticals and Personal Care Products (PPCPs) in the
Environment
We are determining the fate of
PPCPs in the environment, beginning with a characterization of
sources such as wastewater treatment plants and ending with the
characterization of the human body burden and biomarkers of exposure.
Environmental Proteomics
We are developing and applying
proteomics techniques for the detection and characterization of
microorganisms providing ecological services or posing public health
threats. Instrumentation utilized includes liquid chromatography
coupled to robotic spotters for matrix-assisted laser
desorption/ionization (LC-MALDI) analysis, and electro spray
ionization (ESI) tandem mass spectrometry (MS/MS). Our laboratory
features triple quadrupole and time-of-flight (TOF/TOF) mass analyzers.
Health Effects of Human Exposure to Toxic Pollutants
We are studying the extent of
human exposure to toxic pollutants and their associated health
effects by examining biological specimens from adults and children.
Renewable Energy from Biological Systems
We are developing diagnostic
assays for monitoring photosynthetic biomass production and biomass
conversion to hydrocarbons and electricity.
