Hanqin Tian, Ph.D.
Leader
I am an Earth system scientist and educator dedicated to studying the Earth as a complex, interconnected system through an interdisciplinary and holistic approach. My research aims to enhance our understanding of the Earth’s biosphere and its interactions with the atmosphere and climate by utilizing innovative modeling techniques and comprehensive observational data. This work provides actionable insights that support global efforts toward a sustainable future.
My primary focus is on the terrestrial biosphere and its critical roles in global biogeochemical cycles, including carbon, nitrogen, and phosphorus, as well as the budgets of major greenhouse gases such as CO2, CH4, and N2O. I also investigate the impacts of human activities on the terrestrial biosphere’s capacity to provide essential goods and services, including food, energy, and water. By employing an integrated systems approach that combines terrestrial biosphere modeling with AI and machine learning, along with satellite and ground observations, I aim to develop a predictive understanding of how climate change, land use, and atmospheric conditions influence ecosystem structure and function, particularly regarding carbon, nitrogen, and water cycles, as well as the food-energy-water nexus.
In addition to my research, I am passionate about teaching and mentoring. I strive to inspire the next generation of scientists by sharing knowledge and creating a supportive learning environment, equipping my students and mentees to tackle the pressing challenges of our time. My current and former graduate students and postdoctoral fellows have explored a range of cutting edge research themes, detailed below. I welcome highly motivated individuals to join my research team as graduate students or postdoctoral fellows.
