Meiling Gao wins student award at ISEE for distributed sensing research

Meiling Gao won an ISEE Outstanding Student Poster award, for her work, “Population Exposure Assessment Based on a Distributed Network of Low-Cost Continuous Reading PM2.5 Sensors in Xi’an, China”. Last winter we had an opportunity to deploy a sensor network at Meiling’s research sites in Xi’an to measure the spatial and temporal variations in PM2.5 across the city. We deployed the latest generation of the Personal University of Washington Particle (PUWP) monitor, and calibrated it against the BAM, Dustrak, and Minivol. At each node of the network, we collocated the PUWP with a Minivol for further validation of the network’s performance. The deployment was completed in collaboration with the Institute of Earth Sciences of the Chinese Academy of Sciences.


ISEE 2014 Talks

The International Society for Exposure Assessment conference is always a fun gathering and learning experience.  This year is special because it’s being held in Seattle at the UW.

Elena Austin will be presenting recent work we’ve done in the laboratory evaluating low cost Shinyei PM sensor.  We’ve looked at its sensitivity to different sized particles.  We’ve integrated this sensor into both fixed site monitors for distributed sensor networks, as well as small battery-operated personal exposure monitors.  This recent work, combined with previous work by David Holstius, has greatly informed our understanding of how to use this sensor in environmental health studies.

Meiling Gao will be presenting her recent research in Xi’an, China.  She will be presenting a talk on her dissertation research looking at the associations between the built environment and mental and physical health using two validated instruments.  Additionally, she will be presenting a poster on her recent findings from her deployment of several Portable University of Washington Particle (PUWP) monitors developed by my lab in a distributed sensor network last winter in Xi’an.  The monitors recorded very high concentrations in the city, provided good spatial temporal data of PM variations, and compared quite nicely against collocated BAM, TSI Dustrak, and Minivols.

Finally, I will be presenting a poster of work that Hilary Ong (UCSF) and collaborators from Kunming Medical University conducted using the PANDA portable monitors a couple years ago in a pilot study in which we developed a model of children’s PM exposures in Kunming, China.


New P01 Center To Examine the Role of Human Mobility in Infectious Disease Transmission

My group will be working with researchers from UC Davis on a newly awarded NIH P01 Center Grant, “Quantifying Heterogeneities in Dengue Virus Transmission Dynamics”, a 5-year $7.3 million study that will examine as one of its aims, the role of human mobility on contributing to virus transmission and spread.  The study builds upon previous studies conducted by UC Davis researchers on dengue transmission in Iquitos, Peru.  My group is involved in the data core project for the new center.
