Institute for Environmental Genomics

Mission

IEG helix logo

The mission of IEG is to advance scientific research and education in environmental genomics and stimulate bio-economic development in the State of Oklahoma in order to address scientific challenges related to (i) defining gene function, (ii) delineating gene regulatory networks (iii) developing a systems-level understanding of biological systems beyond individual cells, and (iv) creating computational simulations of biological systems. 

Current Research

Three research themes are pursued at IEG:

(i) functional and comparative genomics for understanding gene function, regulation, network and evolution,

(ii) microbial ecology and community genomics for analysis of diversity, composition, structure, function and dynamics of microbial communities related to global change, bioremediation, land use, bioenergy, and agricultural practices using metagenomics approaches, such as functional gene arrays (e.g., GeoChip), high-throughput sequencing, and single cell genomics, and

(iii) development of metagenomic and bioinformatic tools for big data analysis to understand and model ecosystem functioning and stability.

He received a Presidential Early Career Award for Scientists and Engineers in 2001. He received an Ernest Orlando Lawrence Award in 2014. He is a former Editor for Applied and Environmental Microbiology, a current Editor for mBio and a Senior Editor for The ISME Journal. He is a Fellow of the American Academy of Microbiology and the American Association for the Advancement of Science.

Dr. Zhou Appointed Senior Editor of The ISME Journal

Dr. Zhou was appointed Senior Editor for The ISME Journal.  His appointment will begin Feb. 1, 2017 and will continue for three years.  Dr. Zhou was previously a member of the Editorial Board. 

"The ISME Journal seeks to promote diverse and integrated areas of microbial ecology spanning the breadth of microbial life, including bacteria, archaea, microbial eukaryotes, and viruses."

Dr. Zhou's areas of expertise for the journal are: Metagenomics, Microbiomes, Theoretical ecology, Microbial biogeography, Experimental evolution, Genomic technologies, Soil microbial ecology, Climate change microbial ecology, Subsurface microbial ecology, Microbial ecology in engineered systems, Network microbiology, and Systems microbiology.

Energy Secretary Moniz announced the names of the nine recipients of the Ernest Orlando Lawrence Award, which recognizes exceptional US scientists and engineers preforming research supporting the Energy Department mission. IEG Director, Jizhong Zhou, was selected as one of nine recipients.

“These mid-career researchers have made significant advances in fundamental science and technology innovation,” Secretary Moniz said. “They will help sustain America’s research and development leadership. I congratulate the winners for their outstanding achievements, thank them for their work on behalf of the Department and the Nation, and look forward to their continued accomplishments.”

Jizhong (Joe) Zhou (University of Oklahoma) - Biological and Environmental Sciences Honored for his outstanding accomplishments in environmental genomics and microbial ecology, including the development of innovative metagenomics technologies for environmental sciences, for groundbreaking discoveries to understand the feedbacks, mechanisms, and fundamental principles of microbial systems in response to environmental change, and for transformative leadership to elucidate microbial ecological networks and to link microbial biodiversity with ecosystem functions.

IEG research on permafrost thawing highlighted by DOE's Office of Science

June 13, 2017

The U.S. DOE's Office of Science highlighted IEG collaborative work on the impacts of permafrost thawing on microorganisms and resultant changes in carbon degradation rates and release of CO2.

Permafrost's deep layers ... [lock] away [degraded] organic matter...for thousands of years. ... [W]arming could cause permafrost to thaw much faster and more extensively than ever before. ... Organic matter in thawed permafrost can decompose rapidly. As bacteria, fungi, and other tiny organisms break down the matter, they release the greenhouse gases carbon dioxide and methane. ... Greenhouse gases from the thawed permafrost would lead to more climate change, which then could lead to more permafrost thawing – a self-reinforcing cycle.

"This is the most important tipping point," said Jizhong Zhou, a researcher at Lawrence Berkeley National Laboratory (LBNL) and professor at the University of Oklahoma.
