CFL Crew (aka Dune Goons, Beach Rats, Surfers and Modelers)

We love all things wavy, salty, and flooded. We run to the beaches and bays when others run away.

Timu Gallien, Ph.D. (she/her)

Assistant Professor

Dr. Timu Gallien (below, 2nd from left) is an Assistant Professor of Civil and Environmental Engineering at UCLA. She is a former Chancellor’s Fellow and Postdoctoral Scholar at Scripps Institution of Oceanography and holds a Ph.D. in Civil Engineering from University of California, Irvine. Her favorite things to do are windsurf, surf, SUP, snorkel and annoy her grad students and postdocs. 


Bo-Xiang (Burson) Tang (he/him)

Ph.D. Candidate

When Burson (below, left) snorkled for the first time, it made him sea sick. So what did he do next? He learned to scuba dive!  This describes our intrepid Mr. Tang perfectly. His initiative to take action, to help out and most of all to understand makes him a beloved team member. If you need someone to stand thigh deep in estuarine mud to take measurements, he’s your guy. If you want someone to hash out a concept or review an idea, he’s your guy, too. Burson graduated from Hohai University in Nanjing China and participated in the UCLA/Hohai exchange program. It was this program which introduced him to Dr. Gallien and his new goal to be ‘the’ compound flooding guru of CFL.

Maria Winters (she/her)

Ph.D. Candidate

Maria is our resident Mayor of Bermtown and chief pilot at CFL. When she is not hanging out on the natural shoreline project at Cardiff State Beach, she is busy running up and down X-Beach simulations. Maria takes her role as mentor seriously and participates in critical outreach here at UCLA (Society for the Advancement of Chicanos/Hispanics and Native Americans in Science (SACNAS), Center for Diverse Leadership (CDLS)). She is looking forward to continuing her work on shoreline restoration and berm development as it relates to protection of our vital coast communities.

Marie-Pierre (MP) Delisle (she/her)

Ph.D. Candidate

MP is our numerical modeler and coder extraordinaireIf you want something done or have a burning fundamental scientific enquiry that needs traction, MP is our star. She combines her love of modeling with  fundamental science questions and organizes all things CFL. Her love of the ocean and her desire to improve our understanding of natural processes gives her a unique perspective. MP is the co-President of the Graduate Society of  Women Engineers (GradSWE) at UCLA and mentors undergraduates in the center for Excellence in Engineering and Diversity (CEED) and SWE. She’s a true bruin, having spent her time as an undergrad at UCLA balancing life as a student-athlete (swimming) and a civil engineer. If you can’t find her at her desk or doing field work, you’ll be sure to find her in the water, either swimming, scuba diving, or riding the waves.

Joseph Lucey (he/him)

Ph.D. Candidate

It was no surprise that upon meeting Joseph (below, left) for the first time, the CFL team immediately gave him two thumbs up. He has won so many awards, there will soon be a scholarship named after him. But more than that, Joseph is a natural researcher, pushing the limits of his knowledge with questions and queries that probe common assumptions underlying flood principals. Why and how do things flood? His work uses statistics to understand uncertainty. Joseph wears his copulas well (no this is not a hat…) He is our companion on the journey into statistical models of flooding and how it really matters in the real world.  

Margit Maple (she/her)

Ph.D. Student

When Margit is not saving lives (see story), she is working on saving coastlines. Her interest in combining the scientific rigor of engineering with policy will translate the work we do to for those who make decisions for government and municipal entities. She is also a true bruin having received her undergraduate degree from UCLA.

Tony Arreaga (he/him)

Masters Student

Tony is our newest team member and comes to us from UCONN with a BS in Environmental Engineering. At UCLA, he is enrolled as a Master’s Student in Water Resources and Hydrology and plans on continuing his education as a Ph.D. student with the Coastal Flood Lab. His research interests are analyzing the economic costs of coastal flooding and viewing how floods affect different demographics within a community. Tony also enjoys photography, cooking, and especially traveling. He has the distinction of sponsorship from the Gates Millennium Scholars Program and UCLA’s Graduate Opportunity Fellowship. 

— Our CFL Alumni —

Nikos Kalligeris, Ph.D. (he/him)

Former Postdoctoral Scholar

Nikos Kalligeris is currently Principal Researcher (tenured) at the Institute of Geodynamics of the National Observatory of Athens (NOA) and the operational head of the Hellenic National Tsunami Warning Center (HL-NTWC). He holds a Ph.D in Civil Engineering from that other school (USC) with his dissertation “Tsunami-induced turbulent coherent structures.” The primary focus of his research is in the fields of nearshore hydrodynamics and tsunami hazard assessment. Before joining NOA, he collaborated with Professor Gallien as a Postdoctoral Scholar at the University of California, Los Angeles (USA) working on projects related to nearshore hydrodynamics and morphodynamics. His past research topics include experimental work on tsunami hydrodynamics, extensive field work after worldwide tsunami events as a member of the International Tsunami Surveying Team, tsunami hazard assessment studies, coastal flood modeling and harbor resonance. More information regarding Nikos’ current work can be found here.

Yeulwoo (Yar) Kim, Ph.D. (he/him)

Former Postdoctoral Scholar

Dr. Yeulwoo Kim is currently an Assistant Professor at Pukyong National University, Busan, South Korea. He is a small scale modeler with a big scale heart. He received his Ph.D. from University of Delaware with his dissertation entitled A Numerical Investigation of Turbulent Coherent Stuctures and Sediment Transport in Shallow Coastal Zone.”  

Minna Ho (she/her)

Former Masters Student

Minna Ho received her M.S. in 2020 with her thesis “Modeling and Validation of Coastal Wastewater Effluent Plumes Using High-Resolution Nonhydrostatic Regional Ocean Modeling System.” She was co-advised with Dr. Jim McWilliams in the Atmospheric and Oceanic Sciences Department at UCLA.  

As a scientist in the Biogeochemistry Department at the Southern California Coast Water Research Project (SCCWRP), Minna’s research on nearshore physical processes, specifically her work on wastewater plume modeling supports sanitation management discharge decisions at SCCWRP. More information about Minna’s work can be found here.
