Yareli Sanchez 
Senior Scientist

Yareli Sanchez is the technical lead on CWH's applied research projects. She provides technical expertise on stream and green infrastructure monitoring. She has a well-rounded and multidisciplinary understanding of environmental issues and has honed her expertise in science communication and community engagement while at CWH. Yareli manages the Los Angeles River Watershed Monitoring Program and the monitoring, outreach, and educational components of the Drought Response Outreach Program for Schools (DROPS). She also played a critical role in materializing CWH's 2018 and 2019 symposia. 


Yareli's academic research has focused on biogeochemical cycling, urban ecology, riparian ecology, and plant ecophysiology. She is currently a doctoral candidate in the Environmental Science and Engineering Program at the University of California, Los Angeles. Her dissertation is focused on: identifying metrics of stream and upland habitat health, quantifying the habitat value of green infrastructure projects in the urban core, and understanding recreational uses along the Los Angeles River using social media data and expert interviews. Yareli's previous research focused on trace gas fluxes in mangrove forest, sediment augmentation as a sea level rise mitigation strategy, and the ecophysiological stress response of salt marsh plants to inundation.

Yareli was previously a NOAA Knauss Marine Policy Fellow in the U.S. Senate where she had the opportunity to gain hands on experience crafting policy solutions to water resource challenges, engaging constituents and federal agencies on environmental issues, and in elevating state priorities through the federal appropriations process. 


She received her M.S. in ecology from San Diego State University and a B.S. in Biology from California State University, Fullerton. Yareli is looking forward to completing her dissertation.

Courtney Bonilla
Staff Scientist

Courtney Bonilla provides support towards the Council for Watershed Health’s efforts of science-based research and project monitoring. More specifically, projects aimed at monitoring water quality (i.e. LARWMP). She graduated from Chapman University with a B.S. in Environmental Science and Policy and a minor in Computer Science.

Her undergraduate research focused mainly on marine ecosystems and climate change. As a student researcher at Chapman, she studied the effects of climate change on the predatory responses of California sea hares. She also interned with NOAA Pacific Islands Fisheries in Honolulu, Hawaii where she used remote sensing to compare satellite data with ocean floor data to better understand the optimal conditions of NOAA’s underwater sensor.

Prior to working at the Council, Courtney worked for Irvine Ranch Water District, conducting bioassessment surveys using benthic macroinvertebrates and monitoring the water quality of constructed treatment wetlands in the San Diego Creek Watershed.

She enjoys going to the beach, hiking, music, and keeping up with irrelevant celebrity news.
