I am currently a Senior Policy Associate for the Heat Policy Innovation Hub and the Water Policy Program at the Nicholas Institute for Energy, Environment & Sustainability at Duke University. I have a Bachelor of Arts in geography and political science, and a Ph.D. in geography from the University of North Carolina at Chapel Hill.

In January 2023, I defended my dissertation, with research positioned at the intersection of climate and public health. Specifically, I was focused on exploring the utility of existing heat stress indices in modeling health outcomes, assessing microclimatic variations in heat stress using wet bulb globe temperature (WBGT), and developing a forecast tool to predict WBGT across the eastern two-thirds of the United States.

Work Experience

Senior Policy Associate, Nicholas Institute for Energy, Environment & Sustainability at Duke University, 02/2024-Present


Postdoctoral Associate, Nicholas Institute for Energy, Environment & Sustainability at Duke University, 02/2023-01/2024

  • Core to the foundational ideation and conceptual framing for the creation of the Heat Policy Innovation Hub.
  • Instrumental in the development of the framework, foundation, and targeted goals of the Heat Policy Innovation Hub, including multiple research grant proposals currently under review.
  • Invited to speak at the inaugural FEMA Extreme Heat Summit, attended by the FEMA director and representatives from all FEMA regions, sharing practical, real-world tools for extreme heat preparedness to support national policy discussions.
  • Fostered partnerships across local, state, and federal levels, notably co-leading a 'Lunch and Learn' session on extreme heat for FEMA Region 5 and sharing work at the NIHHIS national conference.
  • Key contributor to nascent efforts to develop a robust statewide heat warning system for North Carolina, building off a successful pilot project in select counties in July 2023. This effort involves close collaboration with multiple state agencies, partners at other universities, and the US National Weather Service.
  • Led a small team in creating a best-practices guidebook and strategic roadmap for data extraction tool development, emphasizing code quality, thorough documentation, and stakeholder feedback to ensure the tool's future effectiveness.
  • Served as a subject matter expert on extreme heat and its broader implications, engaging with high-profile media outlets such as National Geographic, The Guardian, NPR, and WRAL.

  • Thought partner and collaborator in numerous conversations with researchers and professionals across Duke University and Duke Health to initiate interdisciplinary research and community-engagements related to extreme heat.
  • Delivered technical training to under-resourced water utilities in North Carolina, equipping them with tools to digitize utility boundaries and fulfill EPA requirements on lead pipe inventories without the need for costly software.
  • Developed tool to assist water utilities complete inventories of their lead service lines, including the data used by the tool (based on tax parcels, address data, and historical satellite imagery) and the user interface of the web application.
  • Engaged with water utility stakeholders, traveling to workshops across North Carolina providing demonstrations of the lead service line inventory tool.

Chief Climatologist and Co-Founder , Klimo Insights LLC, 01/2022-Present

  • Piloting a comprehensive Software as a Service (SaaS) platform designed to alert users of forecasted extreme heat conditions.
  • Developed proprietary systems for climate data analysis, contributing to the company's intellectual property.
  • Actively engaged with stakeholders and clients to understand their climate-related challenges and tailored applications of the solution.
  • Founded company and established business plans, pricing and packaging options, and operational execution strategies.

Research Assistant, Carolinas Integrated Sciences and Assessments (CISA), University of North Carolina at Chapel Hill, 08/2017-Present

  • Conducted field work (2018-2022) to quantify microscale variations in extreme heat using WBGT meters and a mobile weather station, focusing on high schools and suburban environments across North Carolina and Charleston, SC to inform future improvements to the WBGT forecast tool.
  • Developed the first forecast tool in the United States for wet bulb globe temperature (WBGT), a robust and comprehensive heat stress metric, leveraging numerical weather prediction models, which is now operational across the eastern 2/3rds of the U.S., and validated these forecasts through extensive fieldwork.
  • Developed routine for forecasting WBGT based on numerical weather prediction models and NWS gridded products, specifically the NDFD and NBM (WBGT Forecast Tool).
  • Spearheaded innovative statistical modeling to assess the impacts of extreme heat on morbidity and mortality in North Carolina, informing the development of future heat-health warning systems.
  • Developed and streamlined modeling of heat-health relationships for use in the Heat-Health Vulnerability Tool (HHVT), which is a web application predicting the daily number of heat-related illness emergency department visits for counties across NC based on forecasted Heat Index by the NWS.
  • Managed and optimized servers capable of handling terabytes of weather forecast model data, successfully navigating challenges around data volume and virtual hosting.

Graduate Research Consultant, American Studies 291: The Ethics of Climate Change, 01/2018-05/2018

  • Lectured on introducing students to the science behind climate change and the impacts to society, including a focus on the impact of climate change on extreme heat.
  • Assisted students in final projects focused on identifying the vulnerabilities of specific communities in North Carolina, with climate hazards including extreme heat, flooding, and drought.

Graduate Research Consultant, Environment and Ecology 201: Introduction to Environment and Society, 01/2019-05/2019

  • Presented lecture on climate change impacts across a variety of sectors, including the current and future impacts of extreme heat on human health, agriculture, and water.
