I am a PhD candidate at the California Institute of Technology (Pasadena, CA), working with Prof. Kareem El-Badry. I am interested in understanding the life and death of stars through observations of binary stars.
I am originally from Japan but have been living in the US for over 10 years. Before graduate school, I worked with Prof. Kevin Burdge at MIT (Cambridge, MA), where I earned my B.S. in Physics and Music. Outside of astrophysics, I like to play percussion, read books, and bake.
A large fraction of stars live in binary or higher order systems and will interact with a companion at least once within their lifetimes. Understanding these interactions is therefore essential for building a complete picture of stellar evolution. Sripped stars -- which have lost their hydrogen envelopes through binary interactionsn and are therefore products of recent binary interaction-- provide a window into how binary interactions shape stellar evolution processes. They are also progenitors to many astrophysically interesting systems, such as stripped supernovae, compact-object binaries, and gravitational wave sources, making them relevant to a broad range of astrophysical questions.
My research focuses on discovering and characterizing low- and intermediate-mass stripped stars and using those population to contrain binary evolution processes. I am primarily an observational astrophysicist, working across ultraviolet and optical using both photometry and spectroscopy. My research utilizes both archival data and targeted followed-up observations using state-of-the-art facilities such as Keck and Magellan. I also use population synthesis and forward modeling techniques to understand observational and selection biases and connect observed samples to the underlying population.
In addition to research, I am also passionate about STEM education. Over the years, I have taught in K–12 and higher education settings, both locally and internationally. Alongside my thesis research, I am working toward completing Caltech's Certificate of Practice (CoP) in University Teaching.
I believe the role of an educator extends beyond teaching students the course material. As an instructor and mentor, I aim to help students/mentees develop critical thinking skills that can be applied in a variety of settings. Ultimately, I want my students to leave not only with a stronger understanding of the subject, but also greater confidence in their ability to tackle unfamiliar problems and learn independently.
