Junyao Gu
Junyao Gu is a 5th-year Ph.D. candidate in Marine Science and Conservation at Dr. Zackary Johnson's lab. She is interested in using a variety of approaches including computational, DNA, qPCR, and bioinformatics tools to investigate the diversity and dynamics of microbial communities, focusing on marine cyanobacteria and their role in the ocean environment, the relationship among them and biogeochemical cycles, climate change, health risks, and help formulate environmental policies that protect human and ecosystem health.
She is also part of the Seas the Day Podcast team.
Before coming to Duke, she received a Bachelor of Science degree in Environmental Science and a Bachelor of Laws degree in Law from Jilin University, China in 2017. She graduated with a Master’s degree from the Department of Environmental Health and Engineering at Johns Hopkins University in 2019, where she found her deep love for exploring the tiny mysterious microbial world and had a wonderful time doing research in Dr. Sarah Preheim's lab.

Our group broadly studies the abundance, diversity and activity of marine microbes. We are biological oceanographers, marine molecular ecologists, marine microbiologists and biogeochemists. Our research focuses on the marine cyanobacteria Prochlorococcus, the most abundant phytoplankton in the open oceans and an excellent model marine microbe, as well as the biotechnological applications of marine microalgae. We are at the Marine Laboratory as part of the Nicholas School of the Environment at Duke University.

My research focus is on understanding the ecology of microbes through examination of their genes and lifestyles. Bacteria are the most diverse organisms on earth and play a pivotal role in planetary cycling of nutrients and energy. Yet, we have a poor understanding of the factors that drive their diversity and dynamics in the environment. The lab's emphasis is on studying bacterial interactions with the environment at the appropriate temporal and spatial scale including the effect of temperature changes on bacterial populations and bacterial interactions with other organisms. Another area of active research is the response and adaptation of bacteria to emerging pollutants such as antibiotics and nanoparticles.
