I am a PhD student in the MIT Spark Lab, working on the intersection of spatial perception, language grounding and planning for Robotics. I am very fortunate to be advised by Prof. Luca Carlone.
My current research focuses on unifying perception and planning representations for mobile robots. I work on using 3D scene graphs as a symbolic abstraction of sensor data for real-time, on-robot perception, and grounding natural language commands to structured planning representations using these 3D scene graph data structures.
Previously, I completed my masters researching multi-robot
coordination algorithms for a variety of
information-gathering tasks in the Distributed Robotics Lab
with
Before MIT, I was an undergraduate student at Brown University where I built race cars, drones, and found the love of my life.

Scene Graphs

I worked on a variety of projects related to 3D scene graphs and symbolic planning. 3D scene graphs provide a discrete abstraction of continuous high dimensional sensor data. Symbolic planning allows for scalable, verifiable planning and robot execution.

Drone Hardware

I have also worked on a variety of drone hardware projects, including the PiDrone, a low-cost aerial educational platform used in a college-level robotics course at Brown University. In this course, students build, program, and test drones to create autonomous aircraft capable of visual localization and position maintenance using onboard sensors. Additionally, as part of SPARK Lab, I developed a soft aerial manipulator with a perception pipeline for robust object grasping, featuring a novel tendon-actuated soft gripper for fast and adaptive grasping.
