Profile

I am currently taking a break from the hectic life of research to give myself space to mourn my father's recent passing.

In May of 2025, I graduated from the John Martinson Honors Program at Northeastern University, summa cum laude, with a Bachelor of Science degree in Combined Math and Physics. My academic and research journey has been driven by a passion for mathematical modeling, statistical analysis, and the biological and physical sciences.

From 2022 to 2025, I was a research assistant at the Athinoula A. Martinos Center for Biomedical Imaging at Mass General Brigham. I worked in Dr. Jingyuan Chen’s CANDY Lab where my research focused on statistical analysis methodologies for functional PET imaging, specifically fluorodeoxyglucose functional positron emission tomography (fPET-FDG). I have developed novel techniques for integrating fPET and fMRI, improving the temporal alignment of metabolic and hemodynamic signals, and identified systematic biases introduced by state-of-the-art analysis methods. In addition to working on methodological improvements, I have helped collect multimodal neuroimaging data involving EEG, fMRI, and fPET-FDG. My work has resulted in multiple conference presentations and journal publications, including an oral presentation at the 2024 NRM conference and a first-author paper in Imaging Neuroscience.

My last semester at Northeastern, Spring 2025, I worked in Professor Maijia Liao’s lab, where I applied numerical modeling techniques to study microtubule dynamics in neuronal dendrites. This research involved translating mathematical descriptions of microtubule behavior into computational solutions. By implementing a physically-motivated model of microtubule dynamics which easily allows the lab to explore the model's parameter space, I facilitated the lab's investigation of various hypotheses concerning the mechanisms of microtubule shrinkage and growth. 

From July through December 2024, I was a research assistant at CERN’s Compact Muon Solenoid (CMS) experiment under Professor Louise Skinnari. My work focused on improving the track-trigger, an addition to the current Level-1 trigger system which will be implemented for the HL-LHC upgrade in 2026. I assured the quality of tracking algorithm implementations and improved the CPU efficiency of the tracker emulation by 15%. I also conducted thermal testing on the Apollo Rev.2 hardware, ensuring its readiness for the high-luminosity upgrade of the Large Hadron Collider. This experience strengthened my skills in algorithm optimization and hardware validation in the context of high-energy physics.

I balance my academic and professional work with movement, creativity, and mindfulness in my personal life. Ballroom dance has been a constant source of challenge and joy—I compete in 9 dance styles and teach beginner classes at Northeastern. Ceramics provides a soothing creative outlet. As a co-founder of NU Clay Cave, the university’s first ceramics club, I helped build opportunities for students to explore expression through clay and taught sculpting and wheel throwing techniques. Most importantly, meditation and my Buddhist practice ground me, helping me slow down, re-engage with the present moment, and appreciate my life. Through NU Buddhist Group, I led guided meditation sessions and helped organize retreats, building a community based on shared values and mutual support. Through dance, ceramics, and meditation, I find community and varied flavors of joy that complement and reinvigorate my work.
