Created object-masked evaluation pipelines by combining segmentation outputs from MaskDINO into unified foreground masks for monocular depth estimation analysis on KITTI and DDAD datasets. Performed range-based evaluations of Metric3D and UniDepth by analyzing performance across different depth intervals using benchmark metrics, discovering a fall off in model performance as distance increases past 20-30 meters. Compared full-image and object-masked evaluations on KITTI and DDAD, revealing trade-offs in accuracy between global scene estimation and foreground objects.

Gathered and organized data by compiling distances from cement plants to neighboring states and their largest cities into a structured dataset using a Python script with OpenRouteService API, improving data accuracy for further analysis. Implemented a greedy minimum-cost flow algorithm to model and optimize cement distribution across states based on transportation costs, finding ways of reducing carbon emissions from cement transportation and enhancing environmental sustainability.

Wrote a research paper on the use and effectiveness of honey alternatives for overwintering bees and entered Regeneron Science Talent Search under Prof. Zachary Huang.

Worked on a collaborative project to design, build, and test a fully autonomous robot from scratch that navigates a maze to put out a randomly placed candle under Prof. Sinisa Vukelic.

Worked under Dr. Enyuan Hu to write a research poster about characterizing battery cathode materials by using X-ray absorption spectroscopy.
