About me

I’m an applied physicist and engineer with a balance of experience in both theory and experiment, especially in the optics lab and at the electronics workbench.

I’m curious, meticulous, and forward-thinking. No matter the topic, I’m enticed and inspired by unexplored problems and energized by the learning process. I thrive in dynamic atmospheres where I’m absorbing new material on the fly.

I’m also a passionate STEM educator, having taught students at a variety of levels for over 10 years. I’m fascinated by the connections between concepts. I find simple pleasure in uncovering an elegant truth beneath a complex façade, and in viewing the familiar world from new angles. That’s why I enjoy curriculum development and, pedagogically, why I prize learning experiences that empower student-centered discovery.

On a personal note, I’m naturally introspective and reflective. I tend to cogitate on technical problems and life’s cares alike, in a continual mental hum. I enjoy crisp design, a great book (check out my reading list on Goodreads!), a jungle of houseplants, and a clean cup of hand-poured black coffee.

Professional Development

The McGraw Center prepares grad students and faculty for roles as mentors and educators by providing a collaborative environment to engage with contemporary research on teaching and learning. The seminar series placed a concerted focus on creating inclusive and equitable classroom environments.
This workshop explored current techniques and technology used to detect and image exoplanets and debris disks, as well as the underlying science driving the modeling of exoplanetary atmospheres and disk structure. The focus on coronagraphy aligned with the goal of introducing the science and technology of the coronagraph for the Nancy Grace Roman Space Telescope to graduate students and postdocs.
This workshop provided professional instruction in the field of adaptive optics by speakers renowned for their contributions to this interdisciplinary field. Offered for scientists, engineers, researchers, and technicians at the graduate level and above, the workshop combined lectures and laboratory activities with working adaptive optics systems.

  • Assessed student skills and degree of mastery to determine individual needs and, where necessary, modify course curricula and activities to comply with individualized education plans (IEPs)
 
 
 
 
 
Yu's Elite Education
Mathematics Instructor
Sep 2014 – May 2017 Plainsboro, NJ
Yu’s Elite is a family-owned education center with three campuses, offering extracurricular competition prep and accelerated enrichment courses in math, science, and language arts for gifted K–12 students. I was recruited to teach math in private (1–2 students) and group (4–10 students) settings.
 
 
 
 
 
Princeton University
Assistant in Instruction
Feb 2011 – Dec 2015 Princeton, NJ

My experience was a little deeper than a typical TA role involving grading, holding office hours, and organizing and teaching weekly precept lectures. I also taught the mechanical engineering lab portion of the engineering school’s freshman survey course twice, and mentored three graduate students in teaching it in subsequent years. I drew on examples from my own research to generate lessons for the MATLAB unit and designed and taught lab activities for the robotics unit.
