Hello there!
I am a recently-graduated student from UC Berkeley (2025), with BAs in both Physics and Computer Science. I am currently a post-baccalaureate researcher working in superconducting qubit fabrication at the Molecular Foundry at Lawrence Berkeley National Lab, under the direct supervision of Dr. Yashwanth Balaji. I also work with Dr. Yen-Yung Chang on RF simulations in Ansys HFSS, where we are investigating ways to mitigate spurious resonance modes found in many superconducting chip packages. In my free time, I enjoy playing the piano, badminton, and occasionally some gaming. Below is a short list of the projects I am involved in, some of which are still in progress.
Current Research
Below is a list of the ongoing research I am currently involved in.
Box Modes Project
One persistent issue that superconducting chip packaging currently faces are the creation of spurious “box modes” that severely affect the transmission of signal to superconducting devices, and is a major source of loss in the system. This project aims to investigate the origins of these “box modes” – how they are created, and what are ways we can mitigate their effects. This work uses Ansys’s HFSS simulations as the primary driver for experimental results.
This work was also the central focus of my physics honors thesis, completed during my last semester as an undergrad at UC Berkeley, available below. At the present, this project is nearing its conclusion and the paper summarizing this work is currently being written.
Current supervisor: Dr. Yen-Yung Chang
Molecular Foundry
I am currently involved in two separate projects as an associate researcher in the QCMF group at the Molecular Foundry:
- Ion milling: The current state of the art fabrication techniques to make good Josephson Junctions (JJs) involves introducing many sources of TLS loss into the system; this project aims to find alternative JJ deposition recipes which are minimally damaging to the surrounding chip.
- Resonator simulations: Currently, the factors which affect a coplanar waveguide (CPW) resonator’s resonance
frequency, its quality factor, and other properties are not well studied. This project aims to disentangle
each of these parameters, and determine a consistent recipe which produces high-Q CPW resonators at a known
frequency. This project leverages IBM’s
quantum-metalpackage to design the resonators, which are then sent to Ansys HFSS for eigenmode simulations.
In addition to these two primary projects, I am also actively involved in other ongoing projects as a member of the QCMF group.
Current supervisor: Dr. Yashwanth Balaji
Whistler Waves
This was a project I worked on with Dr. Ivan Vasko at the Space Sciences Lab (SSL) into whistler waves the solar wind at 1 AU. These waves are theorized to contribute to the persistent heat flux in the solar wind, which refers to the fact that the solar wind temperature appears to fall off much slower than classically predicted by blackbody radiation. This work was primarily done in MATLAB.
Supervisor: Dr. Ivan Vasko
Coursework
Most of the work that I completed in college (course notes, homework, etc.) are available in my courses repo, save for some courses which do not allow me to share such resources. I’ve also taken course notes for several classes, which are available for download here:
Physics 110B: Electromagnetism and Optics II
CS 170: Efficient Algorithms and Intractable Problems
More to come with these notes, but these two are the only ones so far that I’ve been able to complete!
CS 180
This is a computer vision course I took in Fall 2024. All projects except project 5 were completed using
Python’s scikit-image library, using algorithms learned in class.
Project 1: Coloring the Prokudin-Gorskii Collection
Project 2: Fun with Filters and Frequencies
Project 3: Face Morphing
Project 4: Image Warping and Mosaicing, Autostitching
Project 5: The Power of Diffusion Models
Final Project: Light Field Camera, Gradient Fusion
Physics Notes
As a way to stay sharp on my physics knowledge I am currently collaborating with Andrew Binder, a former Berkeley student and current researcher at Stony Brook University on a project to consolidate all of our physics notes we’ve taken together into a single website and make it available for anybody currently studying physics, check it out here!
