Ph.D. Student at Caltech and NSF Graduate Research Fellow.
I am a Ph.D. student in Aerospace Engineering at the California Institute of Technology (Caltech) and a National Science Foundation Graduate Research Fellow. I develop controls and estimation algorithms for autonomous aerospace systems at the Aerospace Robotics and Controls Laboratory (ARCL) with my Ph.D. advisor Professor Soon-Jo Chung. I am affiliated with the Center for Autonomous Systems and Technologies (CAST) and the Keck Institute of Space Studies (KISS). Prior to coming to Caltech, I worked at NASA Jet Propulsion Laboratory as a Guidance and Control Analysis Engineer.
In my spare time, I enjoy playing ping pong, training for triathlon, growing plants, and traveling.
I use mathematical tools such as nonlinear controls, graph theory, and probability to design and analyze autonomous algorithms for aerospace systems. My previous work includes precise spacecraft formation flying in planetary orbits and distributed estimation of large-scale multi-agent systems.
My life-long passion towards space technology and exploraiton is deeply rooted in rather simple questions: How did the cosmos begin? Are we alone in the universe? I enjoy every opportunity to discuss with others about the wonders of this universe and the exciting technological progress that we are making to answer some fundamental questions.
Being a Japanese-American immigrant and working in a STEM field give me unique opportunities to give back to the communities that I care. I enjoy tutoring local high school students in STEM, mentoring young undergraduate researchers, and coaching Japanese-American students to about studying abroad.
A precise formation keeping of multiple spacecraft in planetary orbit requires continuous fuel consumption. What is the fundamental trade-offs between control precision, sensor precision, and the fuel consumption?
How does a spacecraft in swarm estiamte its relative pose with other spacecraft in effective and tractable manner, as the number a agents in formation becomes large scale?
Here are some outreach and leadership activities that I am involved in.
Through the Rise Tutoring Program, Caltech students tutor the local high school students in math and science courses and help them feel confident in STEM. It challenges me to come up with relatable analogies and adjust teaching strategy depending on students. The students' joy when they understand the concept cannot be traded for anything. That keeps me going.
As a committe member of the SASS at Caltech Y, I help organize guest lectures on social and political issues and science policy. Our topics range from climate change, housing crisis, history of autonomous system, and space policy.
Since I moved to the U.S. in high school, I like to help students from Japan regarding any issues related to study abroad. I have mentored a handful of Japanese students and recently, I gave a talk to a group of high school students at Caltech.
We are excited share that our paper "Distributed Multi-Target Relative Pose Estimation for Cooperative Spacecraft Swarm" received one of the Best Student Paper Awards at the 10th International Workshop for Satellite Constellation and Formation Flying (IWSCFF) in Glasgow.
The Caltech Y opened so many opportunities to get involved outside the lab, such as high school tutoring, Washington D.C. Policy Trip, and the Social Activism Speaker Series. In this Spotlight article, I shared some of the amazing experiences through the Y.
My work on precise formation-flying control analysis, conducted when I was working at JPL, is now available. It presents an analytical approach to quantify estimation precision, closed-loop control error, and fuel cost and provides insight to fundamental trade-offs of for precise keeping.
October 2018, I had an opportunity to participate in one-week long KISS Workshop for Large Constellations and Formations for Exploring Interstellar Objects and Long-Period Comets where leading astronomers, instrument engineers, and mission formulation engineers conducted a feasibility study of visiting once-in-a-lifetime intersteller commet.
