About
I am interested in how quantum states emerge, are measured, and can be modeled in real physical systems. My current work focuses on lanthanide atoms on surfaces, where local symmetry, crystal-field effects, ligand-field contributions, and 4f–5d interactions shape the quantum level structure.
Research
Current Research: Multiplet Calculations and Synchrotron XMCD
My current research investigates the quantum level structure of surface-supported lanthanide atoms. I use multiplet calculations with crystal-field and ligand-field models, constrained by spectroscopic measurements such as XAS, XMCD, and ESR-STM.
A central question in my work is how the 4f electronic structure, local symmetry, and possible 5d contributions determine magnetic anisotropy and spin dynamics in atomic-scale quantum systems.
Internship: Trapped-Ion Quantum Computing
I worked in a trapped-ion quantum computing laboratory, where I gained experience with experimental control systems, including AOM and PID control. This experience shaped my understanding of precision control in quantum platforms.
Internship: Scanning Tunneling Microscopy
I also gained experience in an STM laboratory, assisting with surface preparation and basic STM/STS measurements. This introduced me to atomic-scale surface physics and later motivated my interest in surface-supported spin systems.

Ideas & Conceptual Work
From States to Paths: Anyons and Quantum Exchange
I am developing a philosophy of physics project on whether state-based descriptions are sufficient for analyzing quantum systems, especially in the case of anyonic exchange and braiding.
The project examines how path-dependent topological structures may carry physical significance beyond initial and final quantum states.
Mathematical Formalism for Quantum Mechanics
I presented on the mathematical formalism of quantum mechanics in a philosophy of physics study group, focusing on how mathematical structures shape the interpretation of quantum theory.
Outreach & Science Communication
Women in Science Panel Moderator
Moderated a Women in Science panel discussion, facilitating conversation on research careers, scientific community, and representation in science.
STM Monopoly
Developed an educational board game designed to introduce STM concepts and laboratory research culture in an accessible format.
Schrödinger Cat Party
Developed an educational board game inspired by quantum mechanics. The project was introduced at a science education conference as an example of creative science communication.
Teaching
Independent Academic Mentoring
I have taught and mentored more than 40 students over seven years, focusing on concept-based learning in mathematics and physics. My current teaching includes linear algebra using Friedberg's textbook.
General Physics Laboratory Teaching Assistant
Assisted undergraduate students in experimental physics, including laboratory procedures, data analysis, and scientific reporting.
Linear Algebra Study Group
I am organizing a study group focused on linear algebra and its applications to physics.
