Hello! I’m a third-year undergraduate at the University of Chicago
pursuing a B.S. in computer science with a specialization
human computer interaction
and a minor in physics. My research interests include exoplanet imaging, adaptive optics, and space-based sustainability.
After I graduate UChicago in June 2025, I plan to enter the industry in the optical sciences or in engineering for a few years before
applying to graduate school to pursue a Ph.D. in the Optical Sciences.
I am deeply committed to sustainability and education.
My belief is rooted in the idea that every child deserves access to high-quality education,
and I am dedicated to ensuring that my work actively contributes to making the world a better place to live in.
Outside of computer science and physics, I also love circus arts, photography, tennis, and electronic circuit building.
Research
The Asteroseismic Detection Limits of Ground-Based Transient Surveys
Asteroseismology is the study of internal structures of stars through their pulsations.
M-giant star are much cooler and larger than our sun; the special thing about M-giants is their luminosity pulsates
with long periods, spanning up to multiple months, and with large changes in luminosity. [Image courtesy AsteroSTEP Outreach]
Problem: It is typical practice to use space-based telescopes like TESS and Kepler in asteroseismology. However,
when looking at specifically M-giant stars, space-based telescopes have some inherent drawbacks:
(1) field-of-view is restricted, (2) observation baseline might be too short.
My Proposed Solution: I worked with Professor Daniel Huber at the University of Hawai`i Institute for Astronomy to see if we could detect these oscillations in M-giants
with ground-based transient surveys, consisting of a field-of-view of the entire night sky with observation baselines
of at least 2 years. Using the All Sky Automated Survey for SuperNovae (ASAS-SN) telescope, I found that ASAS-SN can retrieve these pulsations for
M-giants with frequencies below 1 µHz within the 9th mag to 13th mag in the Gaia band. With this, ASAS-SN can characterize
distances for ~5 million M-giants.
Imagine swimming underwater and looking up at the clouds. From this perspective,
the clouds are distorted and moving rapidly. The same concept applies for stars
and our atmosphere: stars twinkle due to variations in atmosphere refractions. These
abberations make it difficult to precisely image extrasolar objects. Adaptive Optics (AO) is a
subfield of astronomy instrumentation aims to reduce these abberations. It involves a Deformable
Mirror (DM) that has several actuators within its mirror that shifts the wave front to fix the
image distortions. [Image courtesy ALPAO]
The National Astronomical Observatory of Japan (NAOJ) Subaru Telescope has an instrument
that works to reduce abberations in order to image exoplanets called Subaru Coronographic
Extreme Adaptive Optics (SCExAO). SCExAO's current DM has 188 actuators that are capable of
deforming the wave front. However, we are in the process of integrating a new 3224-actuator DM
from ALPAO called the AO3k.
I worked with Dr. Olivier Guyon and Dr. Julien Lozi to characterize the movement of each actuator
in the AO3k.
I found three unexpected behaviors with the AO3k inclusing unresponsive actuators,
uneven actuator response, and eleveted actuator response around the mirror edge. I presented these
findings to ALPAO and we sent the AO3k back to France for repairs in these behaviors.
A paper on the opto-mechanical design, integration and lab tests of the AO3k and additional
improvements on SCExAO will be submitted to SPIE in June 2024.
I am passionate about performing in shows with Le Vorris and Vox (LVV) Circus.
My specializations are partner acrobatics and the lyra.
I teach classes with my acro partner, Fabrizio Ferro, for LVV Circus.
I am current the President of LVV Circus in which I direct and write shows and am the liason between
the University of Chicago and LVV.
If you're interested in taking classes in Silks, Bar Aerials, Contortion, or Partner Acrobatics, please reach out to me at aliciamchun@uchicago.edu with
an email header of "Interest in LVV Circus Classes".
We also have quarterly performances and are open to having new performers join our circus. Likewise,
reach out to me with the header of "Interest in Performing with LVV Circus".
I'm currently working on a project that uses Electric Muscle Stimulation (EMS)
to create a human drum "loop pedal". Here is the basic sketch design:

And here's the first prototype iteration in action!

Teaching Experience
In my time at UChicago, here were some memorable teaching jobs I've held:
Afterschool NSP tutor for local elementary, middle, and high school children.
I am currently a Learning Assistant for the UChicago Physics 130s Lab Sequences
My passion for teaching stems from the rewarding experience of seeing students grow and develop.
It's a privilege to be a part of their learning journey, and give them the resources they need to love and enjoy learning.
