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.

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, 2024.
ArXiv Link: https://doi.org/10.48550/arXiv.2405.02502
And three in preparation:

Financial Experience:
In summer 2024, I completed a trading internship at PEAK6 Capital Management where I developed volatility arbitrage signals and pitched trades based on them, a few of which traders executed.
In summer 2023, I completed a trading internship at Belvedere Trading where I developed a statistical tool in Python studying market microstructure, and created an algorithm that the quants used to improve American options pricing.
In summer 2022, I attended a 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:
And a couple of podcasts I sometimes listen to where the hosts play TTRPGs:
