Research

Our team forms partnerships with these microbial communities. This means managing the near-limitless metabolic diversity of the microorganisms while using their services to clean up pollution, produce renewable resources and improve our health. In return, we provide the microorganisms with a good life as they carry out their natural metabolism. It’s a win-win solution. 

We apply the most advanced tools of molecular microbial ecology, chemistry, microscopy and mathematical modeling to think like the microorganisms and, in turn, create systems that allow the microorganisms to provide beneficial services, ranging from sustainable environmental processes and nutrient and energy recovery to making humans healthier. 

Our culture begins with our diverse set of researchers who come from many disciplines within engineering, life sciences, chemistry and more. Partnerships are common within our center, as well as with other groups in ASU, national and international universities and practitioners. 

To date, our center has spun out two Biodesign research centers: 

• Biodesign Center for Environmental Health Engineering
• Biodesign Center for Health Through Microbiomes

Managing microbial communities for societal service is achieved through cross-disciplinary and team-based research in the areas of engineering, sciences, sustainability and biological design.  

Major efforts of our center, include:  

• Mathematical modeling specific to environmental biotechnology. Lab research ranges from fundamental concepts like chemical speciation, biofilms and microbial ecology, to practical applications including the microbial electrochemical cells, wastewater treatment, bioremediation and membrane biofilm reactors. This work is supported by the Rittmann Lab.

• Production of energy or high-value chemicals through microbiological technologies. We make use of microorganisms and their complex enzymatic machinery to carry out reactions that are difficult or impossible through any other known chemical route. Our main research interests are microbial electrochemistry, fermentations and photosynthetic biofuel production. This work is supported by the Rittmann Lab.

• Water sustainability. We minimize the production of waste byproducts and advance the water–energy–food nexus. Our water efforts include drinking water and wastewater treatment, natural aquatic systems, treatment of water at various lifecycle stages, water conservation, valuable material recovery and sequestration of harmful contaminants. This work is supported by the Rittmann Lab.

• Research on microbes. We study the ecology of carbon-rich ecosystems, the interactions and activities of microbes as potential ecosystem drivers, and the genomics and evolution of microbes to track their mechanisms of change. We also focus on novel groups of methane-producing Archaea and interacting bacteria in anaerobic, high-carbon content of natural or human-engineered environments. This work is supported by the Cadillo Lab.

• Systems approach to water quality and treatment. We consider global drivers such as urbanization, climate change, biogeochemical cycles, sustainable engineering and disruptive innovation. 

• Field applications. We work in biological, chemical and physical characterization of soils, biochemical reactive transport and multiphase flow in porous media. Our team works with the ASU Center for Biomediated and Bioinspired Geotechnics to develop and transfer technologies from a proof-of-concept in the laboratory to field scale demonstration projects for a variety of geotechnical and geoenvironmental engineering applications. This work is supported by the Delgado Lab and the Torres Lab.

• Nanomaterials. Our team produces and uses nanomaterials in concert with microorganisms. We work with the NSF Center for Nanoenabled Water Treatment to develop novel nanobiotechnologies for detoxifying recalcitrant pollutants to purify a wide range of waters and wastewaters. This work is supported by the Rittmann Lab.
• Circular economy. We recover economic value of components of wastes. By applying membrane-based techniques, these valuable components are advanced as high-value products to achieve more cost- and energy-effective products. This circular economy tackles environmental challenges, such as greenhouse gases mitigation, while also generating economic benefits. The work, led by Lai and Rittmann, is supported by Global Center for Water Technology, the center for Science and Technology for Enhancing Phosphorus Sustainability and private industry collaboration.
