7/2025 Mylene and Gabriel presented at the Summer Undergraduate Research Academy!
6/2025 Welcome Mylene Imee Dulay and Gabriel Leyva to join the lab for summer research experience!
5/2025 Dr. Li attended AEESP 2025 Research and Education Conference and hosted the workshop "Reviving your Teaching Practice: AI, SoTL and CBL approaches to enhancing student engagement and creating inclusive classrooms".
5/2025 We celebrated the end of the semester at Eureka!
4/2025 By collaborating with Dr. Sina Hasheminassab at JPL, we conduct stationary monitoring of airborne particulate metals at Odyssey Charter School.
.
4/2025 By collaborating with Airthings Inc., we distributed air quality sensors at 150 homes affected by the Eaton fire. We will continue monitoring the long-term change of air quality in these homes.
3/2025 Ehsan, London, Jose, and Hanyang sampled indoor air quality of 20 homes affected by the Eaton and Palisades fires.
1/2025 Ehsan and Hanyang monitored air quality during Border 2 Fire using TARTA, Aethelometer, Atmotube, and QuantAQ sensors.
12/2024 Ehsan presented his research at AGU 2024 during the session A13F: Advances in Methods and Technologies for Emission Monitoring and Exposure Assessment to Hazardous Air Pollutants.
11/2024 Dr. Li is been selected as a recipient of the 2025 40 Under 40 Recognition Program by the American Academy of Environmental Engineers and Scientists (AAEES).
7/2024 Working with Dr. Sabin Kasparoglu and Dr. Brenda E Lopez Reyna from UCD AQRC, we have assembled and calibrated 7 TARTAs for a collaborative air monitoring project between UC Davis, UC Irvine, and UC San Diego along with various environmental justice community organizations.
7/2024 Ayalen Padilla (JJ) worked in Dr. Li's lab through the UPWARD BOUND HCO Summer Academy 2024 Internships. She presented her research on using low-cost sensors to study personal exposure during the poster session.
5/2024 Ehsan presented a poster and displayed TARTA to the attendance of the 2024 Air Sensors International Conference. Dr. Li chaired the session "Sensing and Exposure Assessment of Hazardous Air Pollutants" at the conference.
4/2024 Dr. Li was invited to present at the Environmental & Occupational Health (EOH) Tech Symposium at California State University Northridge.
2/2024 Dr. Li presented our recent work (Measurement of Traffic-related Particulate Metals Using TARTA) at the 11th CRC Mobile Source Air Toxics (MSAT) Workshop in Riverside, CA.
10/2023 Dr. Li presented our recent work (High time-resolution measurements of particulate metals in environmental justice communities) at the American Association for Aerosol Research (AAAR) annual conference.

7/2023 Jimena presented her research work at MESA workshop!
7/2023 A TARTA is set up at an ASCENT site in Pico Rivera, CA. We will look into the comparison between TARTA and Xact for measurements of metal particles.
6/2023 Athena Chaparro, Shane Chapman, Jimena Castillo, and Naomika Raveendran joined the lab as student assistants. Welcome!
5/2023 We have been funded by California Air Resource Board to develop an improved user-friendly version of TARTA for research, air monitoring, and citizen science applications.
11/2022 Our proposal (collaborated with Comite Civico del Valle Inc and UC Davis) has been funded by EPA. We are going to establish a regional air monitoring network in the highly polluted Salton Sea Air Basin to screen for toxic metal hazardous air pollutants (HAPs) at low cost and high time resolution. https://www.epa.gov/newsreleases/biden-harris-administration-announces-53-million-132-community-air-pollution
10/2022 Cecilio Cazares (undergraduate student at SDSU) joined the lab as a student assistant.
7/2022 TARTA is deployed at DOE ARM's Southern Great Plains (SGP) site (collaborate with Dr. Suzanne Paulson at UCLA).
3/2022 TARTA is used for unattended monitoring of toxic metals near downtown Sacramento, CA.
8/2021 Completed the field observations of traffic-related air toxics at Caldecott Tunnel, CA.
