Research Statement
I study how people, households, and firms respond to change and disruption, and what those responses mean for welfare and policy. My toolkit draws on large-scale cellphone mobility data alongside housing, survey, and satellite data, combined with causal inference and applied econometric methods, and a healthy obsession with getting identification right.

PFAS Exposure Risk Dashboard
Per- and polyfluoroalkyl substances (PFAS), known as "forever chemicals," are persistent synthetic compounds detected widely across the U.S. This dashboard translates PFAS exposure estimates across industrial, drinking water, recreational, and dietary pathways into ZIP-level risk scores, enabling community-level analysis to support targeted environmental health policies.

Environmental (Dis)amenities
Uncovering Disparities in Water-based Outdoor Recreation using Cellphone Mobility Data
Published+
From 70M+ outdoor trips, communities of color, rural areas, and disadvantaged groups are significantly underrepresented in water-based recreation. Native Americans travel 3–5× longer distances.
Quantifying Recreational Benefits from Fish Consumption Advisories
Published+
WTP to avoid advisory sites ~$72/quarter; $87 in summer. Full disclosure generates $3.4M in aggregated annual welfare benefits.
Estimating the Economic Cost of Floods: Urban Mobility and Rental Markets
R&R+
On high-tide flood days, visits decrease 5%. Each additional HTF day/year reduces rents 0.25%. Lower-bound annual cost of Presidential Disaster Declaration floods: $4 billion.
When Nature Turns Hazy: How Wildfire Smoke Affects Outdoor Recreation
R&R+
Each additional smoke day reduces visits 13%+. Wildfire smoke caused $21B/year in lost U.S. recreational benefits. Visitors adapt through substitution but only partially offset losses.
Planes Overhead: How Airplane Noise Impacts Home Values
Under Review+
A one-decibel increase in annual day-night sound levels reduces housing prices 0.6–1.0%. WTP for quiet is heterogeneous across income and race.
I Love That Dirty Water? Value of Water Quality in Recreation Sites
Working Paper+
Using anonymized mobile device data on ~22 million residents visiting 30,000 water recreation sites (2018–2022), recreators are willing to pay $8.20/trip for a one-meter increase in Secchi depth. Improving all sites to the cleanest observed would yield ~$56.3B in annual benefits.
Unequal Waters: Socioeconomic Disparities in Recreational Benefits from Water Quality Improvements
Working Paper+
Demand-side factors explain 80–90% of SES welfare gap; geographic access 10–20%. We propose an equity-informed alternative to current Iowa lake restoration prioritization.
Food System
How Do Firms Respond to Political Tensions? Chinese Food Importers
Published+
20% persistent decline in Norwegian fresh salmon imports. "Political hedging" effect: 20% reduction in max import share from any single country three years post-sanction.
Shrinkflation, Unit Price Disclosure, and Consumer Welfare: Evidence from Canned Tuna
Published+
Consumers in disclosure states 130% more responsive to unit prices. Nationwide disclosure raises consumer surplus $2.57M short-term, $5.82M long-term.
Who Goes to Farmers Markets? Food Desert Gaps, Structural Demand, and Policy Design
Working Paper+
~70% of food-desert visit gap is demand-side; ~20% supply. SNAP acceptance closes ~18%; evening hours ~33%; one new market per food-desert CBG ~58%. SNAP delivers highest return per public dollar.
Human Mobility Methodology
Harnessing Human Mobility Data for Applied Economic Research: Current Knowledge, Challenges, and Emerging Opportunities
Published+
Survey covering contributions of mobility data to travel behavior, labor markets, social interactions, and health outcomes. Addresses measurement errors, sampling biases, and privacy trade-offs.
Causal Recreation Demand Estimation with Cellphone Mobility Data: Evidence from 2021 Huntington Beach Oil Spill
Published+
$1.03M aggregate welfare loss; $83k/week losses persisted beyond closure. Integrates empirical Bayes into a two-step random coefficient logit model for low-visit sites.
Evaluating Precision, Privacy, and Representation with Cell Phone Data: Evidence from Cape Cod Beaches
Published+
MWTP $8.92/visit under best practices. Differential privacy reduces MWTP by 65%; relaxed dwell time by 57%. Highlights privacy-accuracy trade-offs in non-market valuation.
The Impact of Texas Senate Bill 8 on Family Care Utilization: Evidence from Large-Scale Mobility Data
Working Paper+
Using GPS mobility data from Texas family care clinics (2021–2022), SB 8 increased administrative demands on day-shift practitioners (+8.74 visits/month) while urban patients visited more but spent less time per visit. Rural and suburban patient visits stagnated, highlighting how restrictive abortion legislation disrupts healthcare access for underserved communities.
