Shan He, Ph.D. (she/her/hers)
I grew up on the campus of Nanjing Agricultural University in China. Playing around in the experimental fields and laboratory buildings, I developed early impressions of biology and agricultural sciences. My true introduction to biology came at the age of seven through a children's science TV program, where I first encountered the word "photosynthesis." I was immediately captivated by plants' ability to produce food for all life on Earth and became curious about the magic behind this process.
Driven by childhood curiosity, a passion for biology, and a deep respect for plants, I majored in bioscience and biotechnology in college and later earned my Ph.D. in plant molecular biology from Peking University. Following my Ph.D., I joined Prof. Martin Jonikas's laboratory at Princeton University, where I was excited to study photosynthesis in an often-overlooked yet globally impactful group of photosynthetic organisms – eukaryotic algae. My research focused on the molecular basis of the algal CO2-concentrating mechanism (CCM), which mediates approximately 30–40% of global CO2 fixation and holds great agricultural potential for enhancing crop yields.
During my postdoctoral research, I noticed that the algal CCM is inducible and only activated when necessary to save energy. However, the regulatory mechanisms behind it remain poorly understood. As I establish my research lab, I am determined to explore how algal cells respond to external signals such as CO2 to activate the algal CCM at the gene and protein levels. This research will contribute to addressing global challenges in food security and climate change while promoting environmental sustainability and economic growth.
Beyond science, I enjoy traveling to places rich in natural beauty, cultural heritage, and historical significance. I also love art, music, fine food, and all the beautiful things created by nature and humanity.
