6 PNNL scientists earn AAAS fellows

RICHLAND -- Six scientists from Pacific Northwest National Laboratory have been named fellows of the American Association for the Advancement of Science for their work to advance science and apply it to real-world problems.

This year's elections bring the total to 46 of researchers at the Department of Energy national lab in Richland who have been named AAAS fellows.

The newest fellows are:

Leonard Bond

Bond specializes in developing methods and instruments that use ultrasound, a high-frequency sound that is inaudible to humans, to examine everything from cells to power plants.

Bond currently uses ultrasonics to help inspect aging nuclear power plants and advanced nuclear reactor systems, but he also has employed it to examine gas pipelines, rocket motors and defense systems, among other applications.

Bond is a PNNL laboratory fellow. He also was the founding director of the Center for Advanced Energy Studies at Idaho National Laboratory.

Liem Dang

Dang develops and uses computer models to study how molecules interact at liquid interfaces.

His models specifically focus on the potential for molecules to be polarized, or have slight differences in electric charge, and how that affects molecular behavior at liquid interfaces. Dang and Tsun-Mei Chang developed a widely used and cited chemical model called the Dang-Chang model, which accurately portrays the properties of water-based systems in changing environments.

His research helps explain how pollutants react in the atmosphere and how toxic metals are transported across liquid interfaces.

Dang is a member of PNNL's molecular theory research group and a fellow of the American Physical Society.

Cesar Izaurralde

Izaurralde researches how carbon and nitrogen cycle within soil, and how soil, water and plants are affected by human actions and climate change.

He has helped develop and improve computer models that examine climate change in agricultural systems and biogeochemical cycles in soil. Izaurralde also has contributed to several climate change assessments and often is asked to provide scientific information regarding climate change to policymakers.

Izaurralde is a PNNL laboratory fellow at the Joint Global Change Research Institute, a collaboration between PNNL and the University of Maryland. He also is a fellow of the Soil Science Society of America and the American Society of Agronomy.

Allan Konopka

Konopka examines the ecology of microbes to understand how they adapt to changes in their habitats, including water and soil that either is above or below the Earth's surface.

He currently studies how microbial communities in below-ground soils affect the movement and chemical form of contaminants like radionuclides at the Hanford nuclear reservation.

Konopka is a PNNL laboratory fellow and is an associate director in PNNL's biological sciences research division. Before joining PNNL, he was a biological sciences professor at Purdue University for 30 years.

Bill Morgan

Morgan's research focuses on the biological effects of low-dose radiation on human health.

He and his PNNL colleagues examine radiation's effects on humans by using a 3-D skin model. Morgan's research in cell and molecular biology, biochemistry and other fields helps protect people against radiation's adverse effects.

Morgan directs PNNL's radiation biology and biophysics low-dose radiation research program. He serves as a scientific representative for several national and international regulatory agencies.

Greg Schenter

Schenter develops mathematical models to advance how scientists simulate molecular behavior.

He calculates how small, light molecules and atoms move and react in solids and in solution. To do this, he considers the effects of quantum mechanics, a branch of physics.

This research is helping build better batteries and alternative fuels.

Schenter is a PNNL laboratory fellow, as well as a fellow of the American Physical Society.
