2025 Science & Stewardship Highlights - National Park Service (.gov)

As a field engineer at the Vancouver Airport Authority, Jessica Chan supports the airport terminal projects team on construction and maintenance projects. Prior to this role, Jessica was an environmental technician at the airport, receiving the national Canadian Airports Council’s Rising Star Award in 2026 for her contributions to responsible stewardship and land and water use practices in the aviation sector. Tell us about your first job at the Vancouver Airport Authority.  I joined the Vancouver Airport Authority’s Climate and Environment team in early 2022, working in a range of areas, including the water quality management program, spill response, hazardous waste management and environmental compliance. A major area of focus involved monitoring water quality during winter operations when aircraft are de-iced, and finding ways to prevent and mitigate glycol loss to the environment.  My work also included sampling and tracking emerging contaminants such as 6PPD‑quinone and PFAS and supporting incident command during spill response events.

AbstractChronic pain (CP) affects more than 30% of the global population and is often accompanied by significant cognitive impairments. Although an increasing number of studies have focused on the pathological mechanisms associated with chronic pain-induced cognitive impairments, most have concentrated on the stage after the onset of cognitive impairments. Currently, the course by which chronic pain induces cognitive impairment has not been fully reported. Therefore, single-cell RNA sequencing were conducted in this study in order to map the mice hippocampus altas before and after cognitive impairments induced by spared nerve injury (SNI) on days 3, 7, 14, and 21. After quality control screening, 53852 out of 64207 cells from 11 samples were retained for subsequent analysis. The reliability of the sequencing data was verified through analysis of various evaluation indicators and sequencing alignment rates.
