2026 LEAP SUMMER MOMENTUM FELLOWSHIP

Overview

LEAP’s Summer Momentum Fellowship welcomes doctoral students in data science interested in having a summer research immersion in climate data science, with the opportunity to apply their data science/machine learning skills in climate modeling and develop research interests in climate data science. In 2026, we are pleased to offer a  new research opportunity in climate science communications. Each fellow receives a summer stipend, travel support, and access to LEAP resources, such as LEAP Pangeo and workspace at Columbia University’s Innovation Hub.

Momentum Fellowship project leads work closely with Fellows throughout the summer on a well-defined, yet open-ended, machine learning and/or science communications research problem in climate data science. Project leads will also guide their Fellows to present their summer research at future LEAP events and other workshops/conferences. 

Momentum Fellows are responsible for mentoring up to two (2) undergraduate students in the LEAP Research Experiences for Undergraduates (REU) program. Each project will host up to two (2) undergraduate students paired with one (1) Fellow.

2026 Summer Momentum Fellows

LFu

LIANLEI FU
Project 1: Tropical Forest Dynamics + Carbon Dynamics in a Warming World (Weng)

Lianlei is a second-year PhD student in Computational and Data Sciences at Chapman University. His path began in forestry at Nanjing Forestry University, where early work on soil carbon models revealed that single-site ecological studies were too limited in scope. This drove him to pursue a global-scale Master’s at UIUC, analyzing climate drivers of Miscanthus yields across hundreds of worldwide sites. Recognizing the limits of traditional statistics, he turned to machine learning and deep learning to uncover hidden mechanisms in complex ecological data. Today he brings expertise in land surface modeling (CLM5) and spatial data pipelines, working toward integrating AI into global climate modeling.

MSHashmi

MUHAMMED SHEHZORE HASHMI
Project 3: Climate Data Science Communications (Lang / Badaki)

Shehzore is a first-year Ph.D. student in Electrical and Computer Engineering at Montana State University, specializing in scientific machine learning and environmental sensing. A first-generation university student from Pakistan, he began his academic journey with limited resources earning his first laptop through freelancing and has since built an interdisciplinary research portfolio spanning AI, embedded systems, power modeling, and sustainable technology. Growing up in a region affected by climate variability, and deeply moved by the catastrophic 2022 Pakistan floods, Shehzore is driven to develop data-driven tools that support climate resilience and infrastructure risk assessment. He currently mentors undergraduate research assistants and serves as both a Graduate Teaching Assistant and Graduate Wellness Mentor, reflecting his strong commitment to collaborative, purpose-driven science.

ZLiu

ZESHENG LIU
Project 4: Probabilistic Forecasting of Cloud Microphysics with Stochastic Interpolants (Lamb / Ko)

Zesheng is a third-year Ph.D. student in Computer Science at Lehigh University, where his research focuses on physics-aware machine learning for large-scale spatiotemporal modeling. His work centers on building robust, data-efficient models that connect climate model outputs from multiple sources to produce physically meaningful, actionable insights — even under noisy or incomplete data conditions. A turning point in his path came after a family typhoon evacuation in Taiwan and a visit to Japan that brought the reality of climate change into sharp personal focus, motivating him to apply his technical skills to problems with real societal stakes. He also holds a strong commitment to mentoring and broadening access to climate data science, informed by his own experience navigating the gap between raw computation and scientific impact.

PPaul

PAPPU PAUL
Project 2: Discovering Simplified Cloud Models with Machine Learning (van Lier-Walqui / Loftus)

Pappu is a fourth-year PhD student in Atmospheric Sciences at UIUC, with a Bachelor’s in Physics from the University of Dhaka. His research applies machine learning to improve cloud and convection representation in climate models, focusing on reducing parametric uncertainty in Earth system modeling. He has presented at NCAR, AMS, and AGU conferences. Originally from Bangladesh, one of the world’s most climate-vulnerable countries, Pappu’s research is deeply personal. Witnessing flooding and cyclones firsthand drives his commitment to building data-driven solutions for climate-resilient communities.

SRyu

SARAH RYU
Project 6: Evaluating Machine Learning-based Convection Parameterizations in CESM / CAM7 (Semie / Yang / Medeiros)

Sarah is an incoming PhD student at UC Berkeley pursuing Environmental Sciences and Computer Science. Her research interests lie at the intersection of climate science and machine learning, with a focus on how data-driven approaches can improve our understanding of atmospheric processes particularly snow accumulation, convection, and cloud microphysics. Motivated by a first-hand encounter with LEAP’s collaborative culture at the 2024 Berkeley Atmospheric Sciences Computing Symposium, Sarah discovered the transformative potential of AI for environmental science and has been eager to deepen that work ever since. She is also a passionate advocate for broadening access to computational science courses across all backgrounds.

VTsao

VALERIE TSAO
Project 5: AI-Driven Simulation Agents for Urban Infrastructure Risk Modeling (Zheng / Li)

Valerie is a 2nd-year PhD student at Duke University in Theoretical, Computational, and Applied Mechanics. Her research sits at the intersection of physics-aware machine learning and probabilistic forecasting, using generative models constrained by physical laws to capture the distribution of stochastic events acting as a foil to classical deterministic surrogates. She recently published a probabilistic interpolation framework for reconstructing sparse temperature dynamics using diffusion-based inpainting enriched with geostatistical techniques, and is currently developing a method that trains directly on sparse data by integrating a Maximum a Posteriori objective with the Advection-Diffusion PDE. She also develops generative frameworks for modeling extreme storm events over the San Jacinto river basin. Originally from Taiwan, Valerie’s drive to study climate is deeply personal shaped by witnessing typhoon damage and learning that rising sea temperatures have threatened the marine ecosystems of her home island.
