Meet the editors

Dr. Michael Aide received his Ph.D. in soil chemistry from Mississippi State University (1982) and a baccalaureate degree in chemistry and mathematics from the University of Wisconsin – Madison. He has been an educator and agronomic researcher at Southeast Missouri State University since 1982. His research interests involve the growth and development of rice in integrated systems involving soil fertility, water management, and

integrated pest management. Rice research has permitted his travel to southeastern Asia, Central America, and Egypt. Dr. Aide has also investigated the use of rare earth elements in soils, particularly attempting to utilize them to indicate parent material uniformity and their fate/transport. Professional affiliations include the American Society of Agronomy, the Soil Science Soc. America, and he is a certified professional soil scientist.

Takahito Nakajima, MD, Ph.D. is a radiologist with a career of over 20 years. He works at Gunma University Hospital and is the Vice Chair of the Radiology Department. His interest is in diagnostic radiology, including CT, MRI, PET, nuclear medicine, and ultrasound sonography, ranging from basic science to clinical studies. In basic research, he has engaged in in-vivo fluorescence imaging, in particular, activatable fluorescence and near-infra-

red based photoimmunotherapy. He has a long history of working in the clinical field and contributes to quantitative imaging of various organs, with contrast agents being one of his research fields.
