Automorphic Forms,
Representation Theory
& Number Theory

Assistant Professor working at the intersection of 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.

Research Interests

My research lies at the intersection of automorphic forms, representation theory, and number theory. At the heart of this intersection sits the Langlands Program — a vast and ambitious framework conjecturing that deep arithmetic information encoded in Galois representations is reflected in analytic objects called automorphic representations. Automorphic forms serve as far-reaching generalizations of periodic functions, while representation theory provides the tools to decompose spaces of these functions systematically, ultimately illuminating fundamental questions in number theory concerning L-functions, Diophantine equations, and the distribution of prime numbers.

Key Components

Automorphic Representations

The core of the intersection. Classical holomorphic modular forms are recast as representations of adelic groups, enabling their systematic study via the tools of harmonic analysis and opening the door to the full power of modern representation theory.

Number Theory & Arithmetic

Galois representations encode the symmetries of roots of polynomials over number fields. The Langlands conjectures predict that these arithmetic objects correspond precisely to specific automorphic representations — a profound bridge linking the discrete world of algebra to the analytic world of automorphic forms.

Representation Theory

Representation theory provides the structural framework for understanding the spaces in which automorphic forms live. By decomposing these spaces into irreducible components, one obtains automorphic L-functions — powerful invariants carrying deep arithmetic information.

L-Functions

Automorphic forms give rise to complex L-functions whose analytic properties — analytic continuation, functional equations, and the location of zeros — are central to resolving deep questions in number theory. Understanding these functions is one of the principal goals of the Langlands Program.

The Trace Formula

The Selberg Trace Formula — and its far-reaching generalization, the Arthur-Selberg Trace Formula — is one of the most powerful tools in the subject. It forges a remarkable connection between the analytic spectral world of automorphic forms and the geometric world of closed geodesics, and serves as a primary mechanism for establishing instances of Langlands functoriality.

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 3013 — Linear Algebra & MATH 4453 — Mathematical Interest Theory

Office Hours: Tuesdays and Thursdays 9:00–11:00 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.

Exam P
Probability
Covers probability theory, random variables, and distributions. Calculus is assumed. 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.
