The Longcore Lab @ UCLA is located within the UCLA Institute of the Environment and Sustainability. Our focus is on issues of urban nature and sustainability, and applied conservation science. Major themes include:
- measurement and assessment of impacts of light pollution at multiple scales and on wildlife, ecosystems, and humans;
- applied conservation planning using spatial tools to gain insight on and guide conservation action; and
- harnessing emerging or underexploited spatial data sources to leverage against complex conservation or sustainability challenges.
Our current and recent projects include:
- Coast Light (Sea Grant)
- LEDs and Terrestrial Wildlife (Caltrans)
- Central Idaho Dark Sky Reserve STEM Network (Boise State Univ./NASA)
- Heat Resilient LA (Sustainable LA Grand Challenge)
- Los Angeles Landscape History (Haynes Foundation)
- Conservation Planning for Rare Plants on San Clemente Island (US Navy)
Team
Joseph Serafino is a fourth year (Class of 2026) Environmental Science major with minors in Environmental Systems and Society and Geographic Information Systems. He loves to try new foods and late night drives. He often stays awake late into the night and hopes to learn more about light pollution’s impact on himself and the environment around him. He is very excited to work with the undergraduate team to analyze light levels around the Central Dark Sky Reserve in Idaho and use GIS to share the data.
Sammy Sisitsky is a third year undergraduate (Class of 2027) majoring in Environmental Science. She enjoys running, camping, field hockey, and watching Jeopardy. She is especially interested in light pollution’s effects on animal life and ecosystems as a whole.
Aditya Murthy is a third-year undergraduate (Class of 2027) majoring in Computer Science and Engineering with a minor in Public Affairs at UCLA. He loves skiing, martial arts, and long walks through the redwoods with his dog. As a Data Analyst and Researcher at the Longcore Lab, he works on improving LA city planning using big data, parallel computing, and machine learning techniques. Aditya is passionate about computer architecture and program optimization, with a long-term goal of pursuing a career in tech law.
Synaia Faust is a fourth year Environmental Science major with a concentration in Conservation Biology and a minor in Geographic Information Systems. She is especially interested in artificial lights’ impact on the health and cultural aspects of human lifestyle, as well as the ecological impacts on other species in our shared ecosystem. In her free time she enjoys running, hiking, crocheting, and cooking. In addition to studying the night sky she also loves maps and learning about all things botany!
Louise Goldman is a second-year undergraduate studying Environmental Science. She is especially invested in combatting urban artificial light overuse having worked on light pollution projects in her hometown of Chicago, and she wants to spread awareness of the biological and cultural impacts of unnecessary light at night. When not researching the night sky, you’ll find her camping under it, playing frisbee, or enjoying live music. She’s excited to work with the NASA Light Pollution Ambassadors!
Ashley Gleason is a fourth year (Class of 2026) undergraduate majoring in Human Biology & Society and minoring in Environmental Engineering. She loves skiing, backpacking, climbing, and hopes to visit all the National Parks in the US. She is passionate about understanding light pollution and its impacts on marine and terrestrial animals. She is excited to work on the Caltrans LED project to research the impacts of light intensity and spectrum and explore mitigation approaches.
