Climate Strategy & Quantitative Analysis

I approach climate and sustainability challenges through economic and systems analysis. My work involves building GHG emissions and scenario models to evaluate carbon reduction pathways, market dynamics, and strategic tradeoffs.

About Me

I approach sustainability as an economic systems problem. My background in economics shapes how I evaluate incentives, cost structures, and market dynamics behind environmental outcomes. Rather than treating climate targets as abstract goals, I focus on how they translate into operational and financial tradeoffs.

My academic work concentrated on econometrics, environmental economics, and industrial organization, building a foundation in quantitative analysis and applied modeling. I’ve extended that foundation through independent projects developing emissions and scenario models to assess carbon reduction pathways and transition planning strategies.

I am seeking roles where structured analysis, market awareness, and economic reasoning contribute to practical, data-driven climate decision-making.

Experience

Work History

Barbuto Brooklyn at the 1 Hotel

Sustainable Operations

  • Designed and implemented waste-reduction and material efficiency initiatives within beverage operations, reducing single-use inputs and improving resource utilization.
  • Partnered with upper management to evaluate sustainability initiatives through a cost-effectiveness lens, aligning environmental improvements with operational and financial performance goals.

Elegant Affairs Catering

Event Operations Leadership

  • Led cross-functional teams in executing large-scale events (1,000+ guests), coordinating logistics and resolving real-time operational constraints under high-pressure conditions.
  • Structured and managed high-volume workflows across vendors and service teams, reinforcing process discipline and execution efficiency.

Analytical Projects & Modeling

Public Investment Modeling

Economic Policy Analysis

  • Independent structured analysis of regional public funding allocation, building a cost-benefit model to evaluate projected economic impact under multiple funding scenarios.
  • Incorporated discounted cash flow logic and sensitivity analysis to support a policy recommendation.

Regional Growth Strategy Modeling

Economic Development Analysis

  • Evaluated business engagement and participation metrics to inform targeted growth strategy.
  • Structured outreach prioritization based on data analysis to support local economic expansion initiatives.

Freight Electrification Cost & Emissions Modeling Study

Emissions & Scenario Modeling

  • Built a Python-based model to evaluate the financial feasibility and carbon emission reduction pathways of electrifying a regional delivery fleet.
  • Performed 5-year Total Cost of Ownership (TCO) analysis and grid sensitivity modeling to demonstrate localized climate impact under different regional grids.

Featured Project Walkthrough

Oatly Freight Electrification Model

Executive Summary

This analysis models a representative 5-route regional freight network (197,000 annual miles) to assess the financial and environmental implications of transitioning from diesel to battery-electric trucks over a 5-year horizon. The framework integrates emissions accounting, discounted cash flow modeling, fuel price sensitivity, grid carbon intensity analysis, and route feasibility constraints (≤250-mile range).

Key Results

Fleet Baseline 308.50 tCO₂ per year
Phase 1 Impact (feasible routes) −27.2% fleet emissions
Per-Route Reduction (U.S. Grid) −50.8%
5-year TCO (Base Case) EV +$84,161 vs diesel
High Fuel Price Scenario EV +$7,580 advantage
EV Incentive ($80k credit) Near cost parity (−$4,161 gap)
EU Grid Scenario (0.25 kg/kWh) −68.1% emissions reduction
Coal-heavy Grid Scenario +2.2% emissions increase

Strategic Insight

Electrification is not universally advantageous. Financial feasibility is highly sensitive to fuel price volatility and capital incentives, while climate benefit is strongly dependent on regional grid carbon intensity. The model supports phased deployment focused on short-haul, high-utilization routes within practical EV range constraints.
