Gengke Lai
I am a Postdoctoral Scholar in the Department of Earth and Environmental Sciences at Vanderbilt University. I study the impacts of climate change and vegetation dynamics on global fire activity by using satellite observations. I’m also interested in changes in fuel moisture content and its relationship with wildfire. A central focus of my work is fire risk modeling in wildland-urban interface and assessing their threat to human communities. I received my Ph.D. in Geography at Nanjing University in China in 2025.

Jialing Li
I am a Postdoctoral Scholar in the Department of Earth and Environmental Sciences at Vanderbilt University. I study global change and ecology, mainly focusing on the land surface freeze-thaw cycle and vegetation phenology, as well as their responses to climate change by using satellite observations. Current focus of my work is to expand the concept of phenology to Earth system and analyze their dynamics. I received my Ph.D. in Geography at Nanjing University in China in 2025.

PhD Students
Xiuyi Wu
I am a Ph.D. student in the Department of Earth and Enviromental Sciences at Vanderbilt University since 2024. My interesting research field lies in vegetation ecology, exploring the impacts of climate change and forest degradation on forest carbon cycling and flammability in the Amazon using Earth system models. I received a B.S. in Geographic Science in 2020, and a M.S. in Cartography and Geographic Information Systems in 2023 at the Nanjing Normal University, China.

Xingyi Huang
I am a graduate student in the Department of Earth and Environmental Sciences at Vanderbilt University since 2024. My current study focuses on vegetation phenology using both remote sensing and ground-based observations at large scales to understand land surface changes in response to climate change. Before joining the Meng Lab, I studied remote sensing and spatial informatics at Wuhan University from 2020 to 2024.

Yi He
I am a Ph.D. student in the Department of Earth and Environmental Sciences at Vanderbilt University since 2025. My research focuses on plant phenology under climate change and human-driven environmental change. I study how artificial light alters seasonal patterns of urban ecosystems, and I am also interested in pollen phenology under climate change. I received a Bachelor of Forestry from Northwest A&F University and pursued graduate studies at Zhejiang A&F University and the University of British Columbia. Before starting my Ph.D., I worked as a Research Assistant at Zhejiang University (2024–2025).

Undergraduate Students
Arisa Okamoto
I am a fourth-year undergraduate student in the Department of Earth and Environmental Sciences at Vanderbilt University. My current research focuses on how climate change and anthropogenic factors like artificial light at night (ALAN) influence pollen season timing, pollen distribution, and plant phenology. I also work as a student worker in the EES department.
Research Interests
Pollen phenology
Machine learning modeling
Zhanyan Shi
I am an undergraduate student majoring in Earth and Environmental Sciences at Vanderbilt University. My current research focuses on the effects of artificial light at night (ALAN) on vegetation phenology in coastal areas using satellite observations. More broadly, I am interested in understanding how human activities affect natural systems and exploring the intersection of environmental science and data science.
