Current Research Projects

Current research projects are focussed on:

  • Mobile monitoring technique to measure air and noise pollution around Philadelphia (Shakya et al., 2019; Cummings et al., 2021)
  • Using geographical information system (GIS) to analyze air pollution data
    • Exploring the effects of land use and land cover on air and noise pollution around Philadelphia
    • Exploring the association of air pollution and environmental noise exposure with socioeconomic and health variables (Conway, 2020)
  • Measuring air pollution on different microenvironments using portable air pollution instruments
  • Indoor exposure of air pollution among school children in Philadelphia
  • Measurement of air pollution around Philadelphia greater region using passive samplers  
  • Commuter exposure to air pollution in underground subways (Shakya et al., 2020

Please refer to research page for more information on research projects and available instrumentation.

My past research projects have been focussed on chemical characterization of ambient atmospheric aerosols from multiple locations e.g. Kathmandu (Shakya et al., 2010, 2017a, 2017b; Kiros et al., 2016), Texas (Shakya et al., 2011; Rutter et al., 2015), Alaska (Shakya et al., 2013), and New Hampshire (Shakya et al., 2012) by using various analytical techniques: spectroscopy (e.g. XRF spectroscopy) and chromatography (e.g. ion chromatography) and other techniques (e.g. Sunset EC/OC analyzer). I have also completed works on measuring the exposure of air pollution among traffic police in Kathmandu, Nepal and assessing their health effects (Shakya et al., 2016; Shakya et al., 2019). My previous work also included chamber experiments to measure the formation of secondary organic aerosol (Shakya et al., 2010, 2013; Rutter et al., 2012) and to analyze large datasets from US EPA's air quality monitoring stations (Shakya et al., 2015) and PA department of environmental protection (Kellenbenz and Shakya, 2021).

Masks:  Which masks work the best? I published results showing poor effectiveness of cloth masks to protect from particles (Shakya et al., 2016).
