Yuji Takubo

North Ave NW

Atlanta, GA 30332

I am an undergraduate student at Georgia Institute of Technology, School of Aerospace Engineering (expected graduation: May 2023), currently intending to enter a Ph.D. program in Fall 2023.

I am also a recipient of a full-ride scholarship from Ezoe Memorial Recruit Foundation since 2020, which will be continued until the academic year 2027-2028.

My research interests include:

Space mission design (astrodynamics & space logistics)
Sequential decision-making (optimal control, reinforcement learning)
Optimization under uncertainty.

I am currently working at Georgia Tech Space System Optimization Group (advisor: Dr. Koki Ho), and Georgia Tech Dynamics and Control Systems Laboratory (advisor: Dr. Panagiotis Tsiotras). I am a former visiting student researcher at NASA Jet Propulsion Laboratory (Section 312A) and Tokyo Metropolitan University.
