Automorphic Forms,
Representation Theory
& Number Theory

Assistant Professor working in automorphic forms, representation theory, and number theory.

Background

I am an Assistant Professor at Oklahoma State University. Previously, I was an NSF Postdoctoral Fellow at the University of Toronto under the mentorship of James Arthur. I earned my PhD from the University of Missouri in 2018, advised by Shuichiro Takeda, now at Osaka University.

I am also a faculty advisor for the Oklahoma State University Chapter of the Association for Women in Mathematics.

Prospective Students

I welcome inquiries from prospective undergraduate, master's, and PhD students interested in automorphic forms, representation theory, and number theory. If you are interested in working with me, please reach out by email with a brief note about your background and interests.

Research Interests

My research is in automorphic forms, representation theory, and number theory, closely connected fields whose influence extends well beyond number theory to touch many other areas of mathematics. Number theory studies deep patterns of the integers, especially prime numbers, the fundamental building blocks of arithmetic. Representation theory studies algebraic structures by realizing them as linear transformations of vector spaces, allowing abstract symmetry to be analyzed using the tools of linear algebra. Automorphic forms are highly symmetric functions that connect number theory and representation theory by encoding arithmetic information in forms that can be studied through symmetry. This interaction has led to major advances on longstanding problems and remains one of the central themes of modern mathematics.

The explicit formulas of analytic number theory relate sums over zeroes of L-functions to sums over prime numbers. This project aims to prove Arthur's 2014 explicit formula for automorphic L-functions in terms of the conjectural automorphic Langlands group, with applications to Sato-Tate conjectures.

Teaching

Teaching Philosophy

My courses and interactions with students are guided by the following axioms written by Professor Federico Ardila at San Francisco State University:

1
Mathematical potential is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries.
2
Everyone can have joyful, meaningful, and empowering mathematical experiences.
3
Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs.
4
Every student deserves to be treated with dignity and respect.

Current Courses: MATH 2153 — Calculus II & MATH 3613 — Introduction to Abstract Algebra

Office Hours: Mondays and Fridays 10:30–11:20 AM, or by appointment.

Becoming an Actuary

Actuaries are analytical professionals who use mathematics, statistics, and financial theory to assess and manage risk. The profession consistently ranks among the top careers for job satisfaction, salary, and employment outlook. Actuaries work in insurance, finance, consulting, government, and healthcare.

Actuarial credentials are granted by two main organizations: the Society of Actuaries (SOA), which focuses on life, health, pension, and finance, and the Casualty Actuarial Society (CAS), which focuses on property and casualty insurance. Most students begin with the SOA pathway. The first two preliminary exams — P and FM — are jointly administered by both societies.

SOA Pathway to Associate (ASA)

To earn the Associate of the Society of Actuaries (ASA) designation, candidates must complete a combination of exams, e-Learning modules, and validation requirements. There is flexibility in the order of completion. Visit the SOA ASA requirements page for full details.

Preliminary Exams — Start Here
Exam P
Probability
Covers probability theory, random variables, and distributions. Calculus is assumed. Offered continuously via CBT.
SOA Exam P page →
Exam FM
Financial Mathematics
Covers time value of money, annuities, loans, bonds, and financial derivatives. Offered continuously via CBT.

Tips for Getting Started

Start Early
Many students pass Exam P or FM before graduating. Employers strongly prefer candidates who have at least one exam passed.
Plan Your Study Time
The SOA recommends roughly 100 hours of study per exam. Begin studying 3–4 months before your target sitting and leave 2–4 weeks for practice problems.
Earn While You Learn
Unlike law or medicine, you can enter the actuarial workforce while still completing exams. Most employers support ongoing exam study through study time and reimbursement.
Use VEE Wisely
OSU courses in statistics, economics, and finance may qualify for VEE credit. Check the SOA VEE page and plan your coursework accordingly.
