Shunichi Ishii, Ph.D.
Staff Scientist

Research Interests and Accomplishments

Dr. Shunichi Ishii is a Staff Scientist in the Microbial and Environmental Genomics Group at JCVI. His research efforts focus on microbial physiology, ecology, and comparative and functional genomics in complex microbial ecosystems. Other areas of interest include biochemical engineering, microbial syntrophic relationships, and metagenomic analyses of functionally defined microbial ecosystems. His specific area of interest now is based on understanding "electron transfer mechanism" within electricity-generating mixed microbial communities. Dr. Ishii employs various genomic, physiological, and electrochemical approaches to address the adaptation and evolution of functional (electricity-generating) microbial ecosystems.  These approaches include studying microbial population dynamics, performing metagenomic and metatranscriptomic analyses, isolating functionally defined microbial species, and measuring electrochemical signals associated with electricity generation in microbial communities. The goal of his research is to comprehensively describe microbial ecosystems and ultimately control microbial diversity and community function in a variety of microbial catalyzed applications.

Prior to joining JCVI, Dr. Ishii was a postdoctoral fellow at the National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan where he worked in the lab of Yuji Sekiguchi on improving electricity generation in microbial fuel cells.  He also worked in the lab of Kazuya Watanabe at the Marine Biotechnology Institute in Iwate, Japan where he studied flagellum mediated symbiosis during syntrophic methanogenesis, and characterized microbial community diversity in cellulose-fed microbial fuel cells. He received his PhD in Bioprocess Engineering from the Tokyo Institute of Technology under the direction of Hajime Unno where he studied the bacterial adhesion mechanisms.  Dr. Ishii earned his bachelor's degree in Biotechnology from Tokyo Institute of Technology.
