Madeleine Siegel

Madeleine is a doctoral candidate in Environmental Science & Engineering at UCLA’s Institute of the Environment and Sustainability, where her research examines climate adaptation, environmental policy, and community engagement. Drawing on qualitative methods including semi-structured interviews with community-based organizations, practitioners, and decision-makers, her work investigates how infrastructure investments can be designed to advance equity and long-term climate resilience.

Her policy experience spans federal, state, and municipal levels. As a Water Policy Research Fellow with the Natural Resources Defense Council (NRDC), she synthesized technical data to assess climate adaptation implications and support resilience planning. At the New York State Attorney General’s Office, she authored policy memos analyzing state-level climate legislation and environmental regulation. At Columbia Law School’s Sabin Center for Climate Change Law, she directed research evaluating how environmental reviews incorporate climate adaptation and land use planning considerations.

Madeleine holds a Master of Science from Columbia University and a Bachelor of Science with Honors from UC Berkeley. Her writing has appeared in the Los Angeles Times and Climate Currents, the publication of UCLA’s Center for Diverse Leadership in Science.

In 2021, she hiked the 2,200-mile Appalachian Trail from Georgia to Maine.

Jennie Bukowski

Biosketch

My background is quite eclectic: before pursuing a career in atmospheric science, I studied the humanities, taught ESL abroad, and even worked in a plant museum and a virology laboratory. While enthusiastic about many subjects, my true passion is earth science. Always fascinated by weather, I eventually switched to studying meteorology and climatology.

My research involves high-resolution mesoscale modeling and ensemble modeling of aerosol-cloud-environment interactions, storm dynamics, and cloud systems in arid / semi-arid regions. I did my dissertation with Sue van den Heever at CSU, which focused on how thunderstorms interact with mineral dust aerosol and the land surface in dry environments, as well as representation of these processes in numerical models. Currently, I work with my postdoc advisors, Daniel Swain (UCLA-IoES) and James Done (NCAR), to investigate precipitation extremes that are connected in time / space and the physical mechanisms that contribute to these extremes in the American Southwest.

When not doing science, I enjoy playing music and learning new instruments, running, biking, hiking, gardening, reading, and over-watering my houseplants.

Ariadne is a doctoral student in the Institute of the Environment & Sustainability at UCLA. Her research centers around marine ecosystem conservation and management, and aquaculture science and policy. Specifically, she is interested in understanding drivers of aquaculture planning and policy, and integrating sustainable aquaculture methods and products into local food systems in California. She uses spatial analysis, policy analysis, and social science methods in her research.

Marie-Pierre Delisle

Jordyn Moscoso

My research is centered on understanding impacts of dynamical ocean processes on biogeochemistry, ecology, and food-web structure. Specifically, my research focuses on the physical processes that control patterns of productivity in the California Current System — one of four Eastern Boundary Upwelling Systems — through idealized ocean modeling. Along with research, I am a member of the Do-it-yourself Dynamics (DIYnamics) team. With DIYnamics, I create content and videos to complement concepts in geophysical fluid dynamics taught in the classroom.

Paige Hoel

My academic passions in the marine world focus on the interactions of coastal biogeochemistry. Currently, my research involves modeling wastewater outfalls, and studying their impacts on coastal carbon and productivity. I hope to expand upon this research so that it can inform policymakers and regional water quality standards. In addition to this research, I hope to incorporate our oceanographic models generated at UCLA into a GIS format, allowing for more user friendly and widespread applications in and out of academia.

Daniel Dauhajre

I investigate coastal ocean dynamics utilizing both idealized and realistic simulations of the ocean. These simulations allow us to investigate unexplored coastal current regimes and diagnose material transport, which strongly influences ecosystem dynamics. 

Daniel McCoy

I am currently a PhD student and member of Dr. Daniele Bianchi’s Ocean Biogeochemistry and Ecosystem Group (OBEG). My research focuses on using observations and regional ocean climate models to study the interaction of geophysics and biogeochemical cycling in Eastern Boundary Upwelling Systems (EBUS).
