People
Driven by the philosophy that understanding the science of fresh water is fundamental to our ability to protect this finite and vital resource, the Center’s scientists apply their unique, interdisciplinary approach to the critical questions that affect water quality and availability around the world.

David B. Arscott, Vice President, Assistant Director, Research Scientist
Broad interests include riverine landscape ecology and dynamics, aquatic invertebrate and algal ecology, aquatic food web
structure and dynamics, habitat conservation, and land-water interactions. Research experiences in Michigan, New Hampshire, Alaska, Minnesota, New York,
Italy, Switzerland, New Zealand, and Antarctica have provided me with a broad spectrum of experiences in aquatic habitats from the arctic tundra to the
European and Southern Alps to Antarctica.

Anthony Aufdenkampe, Associate Research Scientist
Principal Investigator of the Organic and Isotope Geochemistry group
Research interests: investigating processes of organic matter cycling throughout watersheds;
elucidating the interplay between degradation and sorption processes in determining the composition and ultimate fate of organic matter within river systems;
employing diverse analytical and experimental techniques to answer hypothesis-driven questions;
synthesizing observation and theory into quantitative models of various types in order to guide new experiments and theory.

William H. Eldridge, Assistant Research Scientist
Principal Investigator of the Fish Molecular Ecology group
Research interests: understanding and conserving the genetic diversity that is necessary for fish to adapt to changing environments;
identifying population boundaries among freshwater fishes for use in management and conservation; and
investigating the impacts human activities are having on the genetic diversity, demographics and stress response in native fish populations.

David H. Funk, Entomologist, Director of Facilities
Research interests: all aspects of aquatic insect biology, especially the resolution of species using genetics, reproductive biology
and life history data; has combined interests in entomology and photography to produce a large collection of images of aquatic insects in their
native habitat.

Research interests: a variety of applied and basic subjects including population and evolutionary ecology of stream
insects; the role of abiotic and biotic processes in determining the structure and function of stream assemblages; energy and nutrient exchange within
streams and between streams and their surrounding watersheds; and benthic monitoring and water quality assessment.

Jinjun Kan, Assistant Research Scientist
Principal Investigator of the Microbiology group
Research interests: environmental microbiology and molecular microbial ecology of aquatic ecosystems, particularly freshwater and estuaries, with
focus on algal, bacterial, archaeal and viral population dynamics, and interactions with local environments, including trophic interactions, nutrient
cycling, and biogeochemistry.

View profile
J. Denis Newbold, Research Scientist
Principal Investigator of the Ecosystem Processes group
Research interests and area of expertise: The flow of nutrients (primarily nitrogen, phosphorus and carbon) to streams and rivers and how those
nutrients are processed, transformed and transported by the stream and river ecosystem. View profile
Bernard W. Sweeney, Director, President, Senior Research Scientist
Research interests: the role of water quality monitoring in conservation, population, and community ecology of temperate and tropical aquatic invertebrates; pollution
assessment in temperate and tropical streams using macroinvertebrates; the role
of streamside forests in the structure and function of stream and river
ecosystems; factors affecting growth and survivorship of trees in riparian
forests; effects of global warming on stream ecosystems; genetic variation and
gene flow among populations of stream insects; effects of diel and seasonal temperature change on aquatic insect populations; evolution
of facultative parthenogenesis in aquatic insects; bioenergetics and secondary production of aquatic insects; and the bioassay of toxic materials in
aquatic systems. View profile
