He is a registered professional engineer, and an expert on the characterization and control of bioaerosols \u2013 both indoors and out. The focus of much of his work leverages forensic science for wide area surveillance and aerosol disinfection on large indoor scales. Dr. Hernandez holds several patents and has authored over 100 archival publications. He has recently on served four US National Academy of Science committees, focusing on the microbiology of the built environment, bioterrorism research and disease transfer in urban settings.\u003C\/p\u003E\n\u003Cp\u003EPresentation Description:\u003C\/p\u003E\n\u003Cp\u003EConventional industrial hygiene assessments often survey indoor spaces under conditions where occupant activity and particle resuspension potential are not near their maxima.\u00a0 Such assessment practices have the potential to underestimate the respirable particle loads occupants actually experience.\u00a0 In response, some in the IAQ community have suggested systematically perturbing indoor environments in a way that mimics peak occupant activity for the express purpose of conservatively assessing the resuspension potential of airborne particulate matter \u2013 biological or otherwise.\u00a0 Since microbiological materials (bioaerosols) and inorganic materials (dirt) have different resuspension potential, purposeful perturbation of the indoor environment likely yields different particle exposure profiles than those obtained under quiescent\u00a0 conditions, not only with regard to total particle loads, but the fraction thereof that are of biological origins (e.g., mold).\u00a0\u00a0 This presentation will revisit the history of perturbation practices, the recent deployment of new perturbation practices for specific site assessments (residential, office and educational) in a context for introducing\u00a0 a new generation of portable monitoring technologies that can characterize airborne biological materials in near real time.\u00a0 The presentation will close with a discussion of standardizing specific energy delivery paradigms (turbulence) for different built environment scenarios and the advantages of obtaining data from both quiescent and perturbed conditions.\u003C\/p\u003E\n\u003Cp\u003E\u00a0\u003C\/p\u003E\n\u003C\/div\u003E \u003C\/div\u003E \u003C\/div\u003E\n \u003C\/div\u003E\n \n \n \n \n \n \n\u003C\/div\u003E"}]
