Johns Hopkins Bloomberg School of Public Health Associate Professor, Kirsten Koehler, will present at the Department of Chemistry's weekly seminar series 

About Professor Koehler
As an Associate Professor in the Johns Hopkins Bloomberg School of Public Health my goals are to improve exposure assessment methods to inform occupational and public health policy. My research goals involve the use of direct-reading instrumentation to improve spatiotemporal exposure assessment. Direct-reading (i.e. “real-time”) monitors can rapidly assess exposures to various hazards. My Career Development Award involves coupling estimated exposures with a known location to identify occupational sources of these hazards. Contour plots of the hazard concentration over space, known as concentration maps, have recently been used to assess the spatial variability of hazards. Concentration maps have the potential to be powerful because they are easily comprehensible for workers, managers, and occupational/environmental health scientists to locate areas of concern.

In the ambient environment, I am interested in spatiotemporal exposure assessment by pairing direct-reading instruments with a GPS unit to apportion exposures to different microenvironments. I am an investigator on a study in which we are using a Geographic Information System (GIS) to determine whether commuters can reduce their exposure to traffic-related air pollution by changing their route or mode of transportation (driving vs. bicycling). Additionally, I am the P.I. of an award to investigate the indoor exposures for this cohort.

While I believe there is great potential for direct-reading instruments to aid in the identification of exposure hazards, it can be dangerous to apply such a methodology without understanding the uncertainties associated with this new form of exposure assessment. My continuing research interests include investigating the use of traditional spatial statistical methods like Kriging and more novel methods employing Bayesian statistics.
