About

I’m a Ph.D. candidate in Earth Systems and Geoinformation Sciences at George Mason University and a geospatial computational scientist specializing in methods for representing human behavior and populations across space and time. My research develops methods for spatially-explicit agent-based modeling, population synthesis, microsimulation, machine learning, and artificial intelligence (AI), with applications in public health. These methods are designed to extend beyond public health to address other human challenges, such as those in urban systems, climate adaptation, environmental change, disaster response, and national security.

My dissertation, Advancing Spatial Agent-Based Modeling and Microsimulation for Public Health Applications, is advised by Drs. Taylor Anderson, Hamdi Kavak, Amira Roess, and Chaowei Yang. I also hold an M.S. in Geoinformatics and Geospatial Intelligence and a B.S. in Geography, graduating summa cum laude from George Mason’s Honors College.

Since 2024, I have also worked part-time as a geospatial and imagery analyst with the U.S. Department of Defense, applying spatial data science to large-scale datasets and translating analytical findings into insights for senior decision-makers.

I work in Python, R, Java, MATLAB, and SQL (PostgreSQL/PostGIS, MongoDB, Neo4j), build models in NetLogo and Repast/Repast4Py, and map with ArcGIS Pro, ArcPy, and QGIS.

Research

My research advances spatial data science, machine learning, AI and computational modeling and simulation to better represent human behavior and population differences across space and time. I develop methods that address challenges in representing individual decision-making, generating realistic populations, estimating health outcomes at fine geographic scales, and identifying spatial variation in the factors associated with those outcomes.

Public health provides a central application for this work, offering complex problems that require detailed representations of people, behavior, and place. The methods are designed to be transferable to other complex social and environmental systems, including urban systems, climate adaptation, environmental change, disaster response, and national security.

Much of this research is part of the NSF-funded project Data-Driven Modeling to Improve Understanding of Human Behavior, Mobility, and Disease Spread.

Research Areas and Framework

Applied to public health, and transferable to other areas including urban systems, climate adaptation, environmental change, disaster response, and national security.

01Individual decision-making in agent-based models

I develop data-driven methods for representing how individual behaviors respond to changing conditions in agent-based models (ABMs). Rather than assigning behaviors such as vaccination using fixed probabilities, these approaches incorporate relationships between individual characteristics, contextual factors, and behavioral outcomes. This work supports more realistic simulations, such as how health behaviors evolve during an outbreak and influence disease transmission.

02Population synthesis for realistic agents

I develop population synthesis methods that integrate individual-level survey data with population data to represent demographic characteristics, behaviors, attitudes, and perceptions. By extending methods such as iterative proportional fitting (IPF), I investigate how to generate more realistic agents and preserve meaningful relationships among their attributes and behaviors. These methods support ABMs and other applications that require detailed representations of populations.

03Small-area estimation and spatial microsimulation

I develop spatial microsimulation methods to estimate aggregated behaviors and outcomes at fine spatial scales where direct measurements are limited or unavailable, particularly in the public health domain. Through leading the development of SHAPE (Spatial Health and Population Estimator), I integrate survey and population data to generate estimates of 13 health conditions across geographic areas and population subgroups throughout the United States. This work addresses gaps in the availability of fine-scale health data and supports analyses of geographic disparities that cannot be captured through national or state-level estimates alone.

04Spatial data science for health disparities

I use spatial statistical and machine learning methods to investigate how relationships between social, demographic, and environmental factors and health outcomes vary across places and spatial scales. By developing and applying approaches such as multiscale geographically weighted regression and geographically weighted random forests, I examine where associations differ and how these differences shape geographic patterns, such as health disparities. This work can help identify locally relevant factors for further investigation and inform place-based interventions.

05Generative AI for population modeling and simulation

I investigate how generative AI and large language models can support the representation of human populations and behavior in computational models. This work explores the use of LLMs to generate synthetic survey data, represent behavioral characteristics, and support data-driven population synthesis. I am interested in evaluating when AI-generated data can meaningfully complement observed data and how these approaches can improve the representation of human behavior in simulation.

Applications

Across these research areas, I apply computational methods to public health challenges, including COVID-19 transmission and vaccination behavior, chronic conditions and health behaviors such as heart disease, cancer, smoking, and depression, suicide risk, and school-entry vaccine exemptions in Virginia. I am also extending this work to investigate zoonotic disease transmission involving white-tailed deer and interactions between humans and deer.

Although public health is a central focus, the underlying methodological challenges extend beyond any single domain. The same approaches to population representation, behavioral modeling, spatial estimation, and geographic analysis can inform research on complex human-environment systems, including climate adaptation, disaster response, urban development, and the effects of environmental and economic change on human behavior and mobility.

Teaching and Mentoring

Teaching Philosophy

Drawing on my work in spatial data science and computational modeling, I help students develop strong technical skills while learning to apply them to questions involving people, places, and environmental and societal challenges.

My teaching emphasizes systematic, interactive, and collaborative learning, grounded in enthusiasm for the subject and tailored to students’ diverse learning needs. In practice, this means connecting course concepts to current events, pairing step-by-step demonstrations with hands-on exercises, and designing projects that ask students to analyze real-world problems and communicate their findings to an audience. My goal is for students to leave my courses with not only technical knowledge, but also the critical thinking, problem-solving, and communication skills to apply what they have learned in their careers and communities.

Knowledgeable and patient tutor

I had an excellent experience with my tutor Emma. They were extremely knowledgeable on ArcGis and went above and beyond to ensure that I understood the material. They were very attentive and responsive with great communication.

Student review on Wyzant

So patient & knowledgeable!

Emma is amazing, she has an expansive knowledge on anything GIS programming, and does a great job of simplifying it ! She was so good at breaking things down, discussing the options and seeing what my comfort level is. Emma has helped so much with my Geographic Information Systems minor and introductions to ArcGISPro. Don’t hesitate to call her for your GIS needs, she knows her stuff & makes it look easy!
