About:

I am a fifth year Ph.D. student in mathematics at UC Riverside. I am interested in category theory, probability, analysis, and applications of these subjects toward other areas of mathematics and outside of mathematics. 


Education:

Ph.D. in Mathematics, University of California, Riverside (2020–present)

M.S. in Applied Mathematics, University of California, Riverside (2020–2022)

B.A. in Mathematics, Occidental College (2018–2020); Missouri State University (2017–2018)


Research:

I'm currently working with David Weisbart (website) and Adam Yassine on developing a compositional framework for classical mechanical physics, in the vein of their prior work with John Baez

I have two papers in submission or accepted:

Stine, A., Weisbart, D.: A Compositional Framework for Open Kinematic Systems Involving Constraints and Feedback.
ArXiV Link:

Pierce, T., Rajkumar, R., Stine, A., Weisbart, D., Yassine,  A.M.: Brownian Motion in a Vector Space over a Local Field is a Scaling Limit. Expositiones Mathematicae (accepted, to be published 2024) ArXiv Link: https://doi.org/10.48550/arXiv.2405.02502

And three in preparation:

Pierce, T., Rajkumar, R., Stine, A., Weisbart, D.: A Structural Perspective on the Discrete Time Approximation of Brownian Motion in a Local Field. ArXiv Link:

Stine, A., Weisbart, D., Yassine, A.M.: A Compositional Framework for Classical Mechanical Systems Involving Constraints and Feedback. ArXiV Link:

Stine, A.: Categorical Properties and Applications of Abstract Open Systems (March 2025 expected submission date). ArXiV Link: TBD

While I was at Occidental College, I engaged in a research experience for undergraduates. My research advisor was Jay Daigle. The project was studying delta sets of geometric numerical monoids with a single nonminimal generator.


Financial Experience:

In summer 2024, I completed a trading internship at PEAK6 Capital Management where I pitched 5-10 options trades every day for several weeks of the program, over a dozen of which were executed upon by full-time traders, constructed an options portfolio with other interns, and identified these trade opportunities using automated buy/sell limits based on volatility arbitrage signals I developed using Python and proprietary software.

In summer 2023, I completed a trading internship at Belvedere Trading where I learned about options market making, developed tools in Python to assist real-time trading decisions, and created an algorithm that the quants used to improve their pricing of American options

In summer 2022, I attended a one-week program at Jane Street where I discovered some of the exciting mathematical problems that are studied at financial institutions.

LGBTQ+:

I am an openly queer woman. Queer and trans visibility in education, particularly in mathematics and other STEM fields, is valuable as an outlet for students who may feel isolated or have experienced discrimination for their sexual and gender identity in their educational pursuits. Simultaneously, I am available as a resource for faculty, staff, students, or anybody else to educate themselves on LGBTQ+ issues. Please feel free to reach out to me by email or in-person if you have any questions or need resources relating to these identities.

A few links:

Queer Resources Directory - A massive directory of LGBTQ+ resources in nearly every facet of life,

Spectra - The association for LGBT mathematicians,

NOGLSTP - National Organization of Gay and Lesbian Scientists and Technical Professionals, which has also established a scholarship.


Fun Things:

I play a variety of tabletop roleplaying games (TTRPGs for short, the most famous example being Dungeons and Dragons). I dance a variety of partner dances in social contexts. Lastly, I enjoy writing fiction of all lengths (flash, short, and longer-form stories). If you would like to see a writing sample, feel free to email me.

Here are links to a few TTRPGs I like:

Kingdom

Blades in the Dark

Armor Astir

Stewpot

And a couple of podcasts I sometimes listen to where the hosts play TTRPGs:

Friends at the Table

The Adventure Zone
