Overview

Yasukatsu Oshima is affiliated with Tohoku University in Japan, engaging in research at the intersection of environmental science and molecular biology. Their work primarily addresses marine toxins, protist diversity, and chemical synthesis related to natural marine products.

The scientist has published extensively on topics including marine toxins and detection methods, protist diversity and phylogeny, chemical synthesis and alkaloids, marine and coastal ecosystems, microbial community ecology and physiology, marine sponges and natural products, and microbial natural products and biosynthesis.

Frequent coauthors collaborating with Oshima include Keiichi Konoki, Mari Yotsu-Yamashita, Yuko Cho, Takuo Omura, and Shigeki Tsuchiya.

Their publications are often found in specialized journals such as Harmful Algae, Marine Drugs, Chemistry - A European Journal, Chemistry - An Asian Journal, and NIPPON SUISAN GAKKAISHI.
