Who we are:
Margaret Lang
is an environmental engineer specializing in environmental fluid mechanics, fish passage through hydraulic structures, hydrology, and contaminant fate and transfer in surface and ground water. She is currently the chair of the Environmental Resources Engineering Department at Humboldt State University.Steve Railsback is an environmental engineer and ecologist specializing in modeling ecological systems, individual-based ecological modeling, and assessment of instream flow needs for river fish and ecosystems. He is an adjunct professor in the
Mathematics Department and Environmental Systems Graduate program at Humboldt State University and previously was on the research staff at Oak Ridge National Laboratory.Our associates include talented scientists and professionals
with whom we contract as needed for projects. Associates have included software
developer Steve Jackson, environmental engineer and modeler Annjanette Dodd,
ecologist Tamara Grand, John Kadvany of Policy and Decision Science, and field technicians.
We also have strong working relationships and a record of successful collaboration
with a variety of agency and academic research groups. We have completed Research
Joint Ventures with the US Forest Service's Pacific Southwest and Rocky Mountain
research stations; and collaborate with scientists from (for example) the
Helmholtz Center for Environmental Research UFZ (Leipzig, Germany), the
University of Bergen (Norway), Argonne National Laboratory, DePaul University,
and University of California-Berkeley. Margaret and Steve have each advised
a number of graduate students.
What we do:
Our mission at LRA is to provide quality basic and applied environmental research with high quality, focus, and productivity.
Unlike many environmental consultants, we are experienced and skilled at research: developing and testing hypotheses and technologies to answer basic questions and solve management problems. Unlike many university researchers, we can often dedicate substantial time and resources to our clients' specific needs.Additional information and related sites:
Resume of Margaret Lang
Individual-based Modeling and Ecology, by Volker Grimm and Steve Railsback, 2005, Princeton University Press. This book is the first comprehensive monograph on how to build, use, and do science with individual-based or agent-based models.
Individual-based modeling and ecology at Humboldt State University. This site contains extensive information on individual-based modeling projects we have been major participants in, especially the inSTREAM model of instream flow and river management effects on trout populations. The site provides documentation, software, and publications from several major projects conducted in collaboration with Humboldt State's mathematical modeling program.
FishXing, the tool for modeling and analyzing fish passage through culverts and hydraulic structures. Margaret Lang is a key participant in the FishXing program.
