Marcos-Hernandez teaches local high school students about arsenic in water
Project 4 postdoc Mariana Marcos-Hernandez orchestrated an outreach event to a STEM-focused high school in Phoenix, AZ to teach students about safe drinking water. Her team demonstrated using a colorimetric method that even though water might appear clear and "clean" it might still contain arsenic. They also conducted a filter demonstration so the students could see for themselves how a commercially available filter can capture and remove the arsenic.
CEC participates in Franklin Park Zoo's Earth Day Event
The Community Engagement Core participated in the Boston Franklin Park Zoo’s Spring into Action: Earth Day Event on Saturday April 22. The CEC team had a demonstration that showed community members how Boston gets its tap water. We handed informational fact sheets focusing on water quality and other resources. We were able to reach a wide audience of the Boston community and gather information on how residents felt about the quality of their water.
Rudel gives invited Mayo Seminar at Bowdoin
Holly Rudel, doctoral trainee on Project 4, gave the Mayo Seminar for the Bowdoin Department of Chemistry (her alma mater!) on Friday, April 21. The title of the seminar was “Strategic design of sustainable materials for drinking water treatment”.
Project 4 Cross-Country Collaborative Externship
Holly Rudel (Project 4, Zimmerman Lab, Yale) travelled to Tempe, AZ to visit fellow Project 4 trainees Emily Briese (Westerhoff Lab, ASU) and Srishti Gupta (Muhich Lab, ASU) to learn their techniques for surface complexation modelling and density theory calculations. While there, Holly gained insight into how her Project 4 collaborators set up their computational jobs and got to experience life in their labs. Emily and Holly were also excited to support Srishti on her doctoral defense, where they were inspired by the body of research Dr. Gupta has done over the past five years. Holly is excited to continue her research with her ASU collaborators, and the group is looking forward to publishing numerous papers as discussed on the trip.

Novel water filter device deployed in Florence, AZ
Mariana Marcos-Hernandez and lab-mate Alireza Farsad reached out to a community in Florence, AZ, where reports from the Arizona Department of Environmental Quality (AZDEQ) indicated arsenic levels in well water above the MCL of 10 ppb. In one residence, they installed a titanium-modified point of use (POU) system under the bathroom sink that will remove arsenic from the water over the coming months. Using a flow totalizer they will measure how much water has passed through the filter to calculate and monitor when the filter saturates. Upon saturation of the filter they'll demonstrate to the community the amount of arsenic that was removed. This is the first time the team is testing this modified POU system outside the laboratory to obtain realistic operational parameters. Mariana is a MEMCARE-SRC Project 4 post-doc working in Paul Westerhoff's lab at Arizona State University.
CEC participates in Spring into Fitness Event

Quan Lu appointed to endowed professorship
Congratulations to Quan Lu, MEMCARE-SRC PI and professor of environmental genetics and physiology at Harvard TH Chan School of Public Health. Dr. Lu was appointed Cecil K. and Philip Drinker Professor of Environmental Physiology, effective January 1, 2023. His laboratory studies molecular mechanisms underlying complex gene-environment interactions in multigenic human diseases such as asthma and neurodegeneration, focusing on the emerging role of extracellular vesicles in disease pathogenesis, prevention, and therapeutics. His current work surrounds his discovery of a novel intrinsic mechanism known as ARRDC1-Mediated Microvesicles, which plays a key role in intercellular signaling and inter-tissue communication and holds potential as a platform for therapeutic delivery into diseased cells. The endowed Cecil K. and Philip Drinker Professorship honors former dean of the faculty the late Cecil Kent Drinker and his younger brother and former chair of the Department of Industrial Hygiene (now the Department of Environmental Health) the late Philip Drinker. The Professorship was created in 1975 through the merger of two funds established by the late James H. Rand, Jr.

Charlotte Wirth wins prestigious KC Donnelly Externship Award
Congratulations to Charlotte Wirth, doctoral candidate and Project 2 trainee in Quan Lu's lab at HSPH, on winning a 2022 NIEHS Superfund Research Program KC Donnelly Externship Award. Charlotte's externship will entail research at the University of California, Berkeley SRP Center, with guidance from Christopher Chang, Ph.D. Charlotte studies how lead exposure affects immune cells called microglia. For her externship, she will apply a molecular labeling technique to a culture of microglia to see whether lead exposure increases cellular stress. She hypothesizes that cellular stress may trigger the release of molecular signals from microglia that might contribute to inflammation and neurotoxicity associated with lead exposure. Her findings could help inform the identification of biomarkers, or biological signs, of cognitive disorders.

Tamarra James-Todd co-leads 2nd Environmental Justice Boot Camp
More than 70 trainees, professors, community advocates, and folks with a variety of backgrounds came together on August 15th and 16th for an in-depth online boot camp on the theories and methods to study environmental health disparities and environmental justice (EJ).
This boot camp was co-led by Dr. Tamarra James-Todd, an Associate Professor in the Departments of Environmental Health and Epidemiology at Harvard TH Chan School of Public Health and Dr. Joan Casey, an Assistant Professor in the Department of Environmental Health Sciences at Columbia’s Mailman School of Public Health.
The creation of this yearly EJ boot camp was driven by a lack of training opportunities surrounding designing studies and implementing methods/statistical analyses for evaluating environmental health disparities and environmental injustices. The popularity of the two-day crash course in EJ in 2021, led to its continuation this past August.
