Linking EMR and Exposome Data for Risk Prediction and Interventions: A Translational Approach

Precision medicine (PM) is a medical model that proposes the customization of healthcare, with medical decisions, treatments, practices, or products being tailored to the individual patient.  An individual’s “Social Determinants of Health” (SDOH) have been demonstrated as a key factor in obtaining successful clinical outcomes for individual patients which necessitate individualized interventions.  Two major problems exist in addressing SDOH within a clinical setting.  First, interventions that have shown to be successful in addressing challenges presented by various Social Determinants of Health often scarce and span outside of those services that are available and/or reimbursed within a healthcare setting.  Because of this, it is critical that these resources can be deployed to the patients who will benefit the most.  Second, identifying those patients who will most benefit from those interventions is problematic because of the limited information on SDOH contained in a typical Electronic Medical Record (EMR).  This talk will walk through a proposed research design to use geo-spatial SDOH data, the exposome, as a proxy for individual-level SDOH data.  I propose to test the hypothesis that exposome data, linked with EMR data, can better predict risk of hypertension.  I will also propose a method for external validation and discuss how this might be applied to specific care interventions.

Climate-driven urban heat and its adaptation at a large scale

Abstract

Among many globally recognized environmental problems such as water scarcity, air pollution, and energy security, heat stress is one of the most severe climate-driven threats to the human society. The situation is further exacerbated in urban areas by urban heat islands (UHIs). Absent measures to ameliorate them, the problems associated with heat stress are expected to intensify due to rapid urban development coupled with climate change. One significant barrier to heat mitigation through urban engineering is the lack of quantitative attribution of the various surface processes toUHI intensity. In this seminar, the intrinsic mechanism of UHI and its quantitative attribution at a large scale will be presented. Using a newly developed sub-grid modeling framework, I will demonstrate how surface aerodynamic, hydrological and anthropogenic processes contribute to UHIs. I will further discuss how these mechanistic insights could be used to assess the effectiveness of various commonly-proposed urban adaptation strategies individually and collectively. UHIs also interact with heat waves and climate change. I will also present how UHIs interact with heat waves under present-day and future warmer climates, and how global urban temperatures change with climate change.

 

Bio

Dr. Lei Zhao is an Assistant Professor in the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign (UIUC). He received his Ph.D. in atmospheric and environmental science from School of Forestry and Environmental Studies at Yale University. Before joining at UIUC, Dr. Zhao was a postdoctoral research fellow in the Program in Science, Technology and Environmental Policy (STEP) at Princeton University. Dr. Zhao obtained his B.S. degree in Physics and Atmospheric Physics from Nanjing University in China. His research concerns the physical and engineering processes in the Atmospheric Boundary Layer where most human activities and environmental systems are concentrated, with a particular focus on built surfaces and urban environments. He combines theory, numerical modeling, remote sensing and in situobservations, and cutting-edge statistical methods to study environmental fluid mechanics and land-atmosphere interaction that relate to urban environments, microclimatology and hydrology, climate change, climate impacts and adaptation.
