Dr. Sonia Tiquia-Arashiro is a Professor of Microbiology in the Department of Natural Sciences at the University of Michigan-Dearborn campus (ÂÜÀòÉç-Dearborn).  She joined the University in 2003 and has been working as an Environmental Microbiologist for over 20 years. Dr. Tiquia-Arashiro did her graduate work at the University of Hong Kong and received her Ph.D. in Environmental Microbiology in 1997. From 1998 to 2003, she was trained in the laboratories of Dr. Thomas Richard (Iowa State University, USA), Frederick Michel J. (Ohio State University, USA) and Jizhong Zhao (Oak Ridge National Laboratory, USA). 

Her research takes a multidisciplinary approach to understand the ecology, physiology, and genetics/genomics underlying important microbial processes in aquatic and terrestrial ecosystems, and the biotechnological  and environmental applications of microorganisms. Her research expands our understanding of the tree of life, while simultaneously developing solutions to address the impacts of human activities on the environment which can be divided in three areas, all of which have basic research components; several have considerable public interest, and some have an applied component.  These three main areas include: (1) Microbial ecology of aquatic, terrestrial and engineered systems; (2) Applications of environmental microbes in biotechnology for clean water, renewable energy, global climate change, public health, industrial and agricultural practice and healthy ecosystems; and (3) Waste processing biology and microbiology. 

Her publication record has included over 90 articles in peer reviewed journals and published five books.  Her first book, draws on the work of many great scientists on the application of ecogenomic sensors on autonomous platforms in the ocean.  The second book, , presents an elaborate overview of thermophilic carboxydotrophs and their possible benefits to biotechnology and sustainable agriculture and production.  The third book, , provides an extensive overview of the current research worldwide on the use of extremophiles in the biosynthesis. The fourth book, covers a unique group of fungi that thrive in extreme environments and their biotechnological significance. The fifth book, , provides historical perspective of the technology and its evolution over the years, but also most recent examples of up-scaling and near future commercialization.

Her current projects span across disciplines that engage students and the public in water quality issues particularly on the impact of urbanization on the ecology and health of  watersheds in Michigan. She is utilizing the amazing diversity of organisms and ecosystems of the Rouge River watershed to assess antibiotic resistance and heavy metal driven co-selection of antibiotic resistance in surface waters and sediments. Her team installed along the Rouge River to monitor temperature, humidity, water temperature and water level in real-time.

Dr. Tiquia-Arashiro has served on various national and international committees on issues related to the significance of trace organic pollutants to drinking and recycled water quality. She is the regional editor of the journal Environmental Technology.
