Research Intern at Fujitsu Research of America 

Location: Santa Clara, CA 

The Space Data Frontier Research Center at Fujitsu focuses on combining research across multiple technical fields to address large-scale societal and industrial challenges. These challenges require new approaches that integrate artificial intelligence, sensing, modeling, optimization, and domain knowledge. Our goal is to develop evidence-based scientific tools that support decision-making, improve operational efficiency, and accelerate innovation across industries. 

We are seeking exceptional research interns to join our Space Data Frontier Research Center Lab in Silicon Valley to work on next-generation maritime intelligence and port operations optimization. This project aims to develop an integrated decision-support framework that combines multi-source sensor fusion with port operations visibility and what-if planning. The framework will use heterogeneous data sources, including SAR imagery, optical imagery, AIS, RF signals, and port-area imagery, to track vessels, estimate operational states, diagnose congestion, and support improved port planning and control. 

The internship duration is 3 months. 

Job responsibilities 

Building on an existing AIS-based congestion-modeling pipeline for the San Pedro Bay port complex (Ports of Long Beach and Los Angeles), the intern will deliver (a) machine-learning models that forecast vessel Estimated Time of Arrival (ETA) at the berth, and (b) an interactive operational dashboard that presents predicted Congestion Index (CI),  ETAs, port-state KPIs, short-horizon congestion forecasts, and weather-event annotations. The intern joins an active project with an existing data pipeline, a defined CI, and an early XGBoost / Ridge baseline.

Machine Learning

• Develop and benchmark gradient-boosted (XGBoost, LightGBM) and regularized linear (Ridge, Lasso) forecasting models for ETA.
• Use TimeSeriesSplit cross-validation and Bayesian hyperparameter tuning (Optuna) to ensure causal, leak-free evaluation; report skill scores against persistence and naive baselines.

Operational Dashboard

• Build an interactive dashboard in Streamlit (or Plotly Dash) presenting predicted ETAs for inbound vessels, current port-state KPIs (queue length, berth occupancy, CI), 1h / 3h / 6h congestion forecasts with uncertainty bands, and weather-event overlays.
• Implement geospatial visualizations (vessel positions, terminals, anchorage zones) using Folium, Plotly Mapbox, deck.gl, or equivalent, with drill-down filtering.
• Include a model-performance panel (rolling MAE / RMSE, predicted-vs-actual, drift indicators) for stakeholder trust.
• Package the dashboard as a reproducible repository with documentation, configuration, and a containerized deployment path (Docker or Streamlit Community Cloud).

Requirements

• Currently enrolled in a master's or PhD program in computer science, data science, civil / transportation engineering, operations research, or a closely related field.
• Strong Python with pandas, NumPy, scikit-learn, Matplotlib / Seaborn, and at least one of XGBoost / LightGBM.
• Solid foundation in supervised regression with time-series concepts (lag features, temporal splits, target leakage).
• Demonstrated experience building interactive dashboards in Streamlit, Plotly Dash, or equivalent — please share a public example or repository.
• Familiarity with version control (Git) and reproducible workflows.

Preferred Skills

• Hyperparameter tuning with Optuna; model interpretability with SHAP.
• Geospatial Python (geopandas, shapely) and visualization (Folium, Plotly Mapbox, deck.gl, Kepler.gl).
• Maritime / transportation / AIS data exposure; experience with weather and environmental data (NOAA, Open-Meteo, ERA5).
• Optional: PyTorch (for sequence models), Docker, Streamlit Community Cloud / AWS / GCP deployment, queueing-theory or port-operations background.
