Chengfei He, PI

I’m a climate modeler, data scientist, and keyboard enthusiast with a passion for advancing our comprehension of climate change.

I began my Ph.D. in the Atmospheric and Oceanic Sciences (AOS) department at the University of Wisconsin–Madison. However, due to my advisor’s new faculty appointment, I transferred to The Ohio State University, where I ultimately received my Ph.D. Prior to this, I earned both my Bachelor’s and Master’s degrees in Meteorology from the Nanjing University of Information Science and Technology in China.

Currently, I am an assistant professor at Northeastern University in Boston. Prior to Northeastern, I did postdocs in the department of physical oceanography at WHOI and RSMAS in the University of Miami.

My research falls broadly under two fundamental questions: (1) What are the causes of past and future changes in oceanic and atmospheric circulation and climate variability? (2) How can we quantitatively interpret these changes and their impacts? I use an interdisciplinary research approach that combines a hierarchy of climate models, isotope-enabled modeling, statistical and machine learning techniques, and observations/paleoclimate proxies, aiming toward a better understanding of the physical processes that govern climate dynamics in the past and future.

Feiyu Huang, PhD student

I am a climate scientist and paleoceanographer dedicated to understanding the mechanisms driving climate and ocean change. I earned my Bachelor’s degree from the School of Geographic and Oceanographic Sciences at Nanjing University in China, where I conducted a research project of paleocenography, funded by NSFC undergraduate program. I am currently pursuing my Ph.D. in Department of Marine and Environmental Sciences at Northeastern University. My previous research focused on the evolution of marine key biogeochemical element cycles since the Last Glaciation. Currently, my work centers on the mechanisms underlying interhemispheric thermal contrasts across multiple timescales. In my research, I integrate a hierarchy of model simulations, instrumental observations, geochemical proxies, and data assimilation to better understand the coupled climate–ocean system.

Ranya Jain, Undergraduate

Hi! I’m an undergraduate at Northeastern University pursuing a B.S. in Data Science and Ecology & Evolutionary Biology, currently a sophomore. I’m passionate about using data to explore environmental systems, especially our oceans and the deep sea. I’m really interested in how we can use data to learn more about our planet and its changing climate.
