Hi, I'm Eleni

I'm a Master's student in Operations Research at Columbia University with interests in optimization, machine learning, and data-driven decision making.

My work sits at the intersection of analytics, optimization, and AI, with applications in public policy, sustainability, healthcare, and operations.

Areas of Interest

  • Optimization (MILP, Constraint Programming, Gurobi, OR-Tools)
  • Machine Learning & Predictive Analytics
  • Reinforcement Learning
  • Deep Learning
  • Dynamic Pricing & Decision Making Under Uncertainty
  • Agentic AI and Retrieval-Augmented Generation (RAG)

Selected Projects

  • Childcare Desert Elimination – Facility location optimization for improving childcare accessibility
  • NBA Scheduling Optimization – Constraint Programming approach for sports scheduling
  • Healthcare Risk Classification – Machine learning models for patient outcome prediction
  • EV Fleet Charging – Deep Q-Network (DQN) for online electric vehicle charging decisions
  • Dynamic Pricing with Thompson Sampling – Bayesian learning for revenue optimization
  • SolarIQ NYC – Geospatial and financial analytics platform for rooftop solar investment screening
  • Agentic AI Workflows – Tool-augmented LLM systems with memory and RAG capabilities

Currently Exploring

  • Optimization + Machine Learning Integration
  • Decision-Focused Learning
  • Sustainable Energy Systems
  • Reinforcement Learning for Operations
  • AI for Decision Support

Feel free to connect if you're interested in optimization, analytics, AI, or operations research.
