Position Graduate Assistant, LSU Email jgarc86@lsu.edu Office 363 Lockett Hall CV Web · PDF

Hello! I’m a PhD student at LSU studying mathematics. My research interests include topology and combinatorics, with a particular fondness for matroids.

I like getting involved in my community. I currently serve as secretary and webmaster of LSU’s AWM chapter, and as webmaster for LSU’s RTG. I also participate in the informal geometry and topology seminar and the DTC/informal combinatorics seminar.

I manage the department’s 3D print lab. More on that soon.

Lately
Working on a paper. Playing around with the websites I manage. Probably in my home office talking to my plants and reading.

Teaching

On this page you can find information relevant for students taking one of my classes, including times, location, policies, and office hours.

For classes where I am the primary instructor, this page doubles as a course syllabus and will include homework due dates and course content.

Quick Links

MATH 1431: Business Calculus, Spring 2026

Time & Location
All sections meet in Library 232.
  • §7: Monday 13:30–14:20
  • §11: Tuesday 09:30–10:20
  • §19: Wednesday 13:30–14:20
Grading
Per lab period, a student may earn 10 points total:
  • +7 points for attendance.
  • +3 points for correct solutions to end-of-class quizzes. Partial credit given.
A student may lose points for the following:
  • −0.5 points for tardiness (showing up after roll).
  • −1 point for use of a cell phone, increasing by 1 point per infraction.
Overview
The first 30–40 minutes of class will be devoted to reviewing concepts from the main lecture and homework. I encourage students to come with questions, specific or otherwise. Students who feel comfortable with the material may open Pearson to work on homework; collaboration and notes are permitted, so long as the volume of conversation is reasonable. Use of generative AI for homework is prohibited.

I enforce a strict no-phones policy. I expect all phones to be in bags, out of sight, and on silent. The required calculator for the course is affordable; graphing calculators and Desmos are also allowed.

Office Hours
Lockett 363, Monday, Wednesday, Thursday, and Friday 07:30–08:20; Tuesday 07:30–09:20.

Office hours do not require an appointment. I also hold hours by appointment, so email me if you cannot make a posted time. I welcome everyone, but prioritize students enrolled in the sections for which the hours are designated.

Absence
I excuse absences for the following reasons:
  • Email me day-of if you are sick, have an emergency, or there is hazardous weather. No note necessary.
  • Email me in advance if you have plans or appointments during class.
  • Email me a sick note or proof of valid excuse under LSU PS22.

If you miss class, it is your responsibility to inform me so you can make up missed content or quizzes. I offer retakes during office hours by appointment. In the first two cases above, retakes should be completed within 2 weeks of the absence; otherwise I deduct 30%. If you need more time, reach out to discuss.

I typically take roll within the first 5 minutes of class. It is always better to be tardy than absent.

3D Print Lab

The LSU Math 3D Print Lab is located in 373 Lockett Hall. I manage the lab and handle print requests for members of the LSU Mathematics Department.

How to Request a Print

Print requests are open to members of the LSU Mathematics Department, including faculty, staff, and graduate students. To submit a request, email me at jgarc86@lsu.edu with the following:

  • Your STL or 3MF file.
  • Your preferred material and color, or a note that you are flexible.
  • Any deadline or urgency, and any notes on quality versus speed.

I do not guarantee turnaround times, but I will let you know if a request is not feasible. Please check the filament inventory below before specifying a material; if you need something not in stock, ask and I may be able to source it.

Comics

A selection of comics I have drawn. Subject matter varies. Clearly inspired by xkcd. All humor is derivative, but mine is especially so.

I like to take inspiration from the Catholic Church's calendar for my office hours.

The Mesozoic was far weirder than people give it credit for.

According to my partner, this is how mathematicians speak.

My friends should NOT give me access to their devices.

Sometimes we need the little things.

ANOTHER website?

May 23rd, 2026

Hey yall!

Oh my GOODNESS the draft is finally live! The long-awaited rewrite of the LSU RTG website is finally up! Some new features:

  • The site has COLOR! Instead of a plain, white expanse, I leaned in to the blue and gold that the site originally used as highlights. I'm still not quite sure why the site was originally using blue instead of purple, but ce la vie.
  • Completely redesigned the people page to use dropdowns instead of just dumping all the people onto the page. Also, the python build script reads plaintext so it's super easy to add new people as needed!
  • Eliminated the activities page in favor of an expanded navigation bar.
  • Combined multiple, separate webpages into a single, tabbed page. This might change in the future for specific pages (workshops, DRP, etc), but was critical for the current site size to make navigation faster.
  • Changed the icon and decorations!

Actually, a bit of a story behind that last item…

The original torus design with folded paper didn't scan as well as I hoped. I couldn't figure out what I wanted. At one point, I even ended up browsing Escher's artwork. Hyperbolic tilings piqued my interest but the impossible Penrose triangle were just as appealing. I eventually was reminded of my love of knots and settled on a right-handed trefoil taken from a minimal grid diagram and rotated 90°.

But this is revealing a secret. See, that drawing is fairly notorious: Does it look like a trefoil on first glance? Because if you squint, it might look more like a figure 8. Both I and a friend got a tripped up at one point, but if you flip a few crossings, all's well. One of my professors even thought I had made a mistake while trying to draw the figure 8! While I'd love to say this was an intentional choice… it wasn't. I think it'll make a really fun trivia question some day.

I have a lot planned still! I'm going to revisit my custom build script (I'm on version 5) and add some of the custom code I have for writing calendars. Additionally, there's a lot the RTG has planned, so that content is forthcoming. In particular, one of my friends is going to be running a program next year and I'm really excited to work with her to design something custom with a home-cooked flair.

Best,
Hailey

New website design!?

May 17th, 2026

Hey yall!

As you've noticed (presumably; you are on a new page, after all), I've updated this website considerably. This shouldn't come as a great shock to anyone. While I like the retro, deeply personal design I was using, it wasn't the most efficient to update. A clean design, prioritizing simplicity and modularity, was the solution.

There are, for now, three new sections. The blog section is, as you've been able to discover, a place for blogs and updates. I'm excited to write stories, information, and the occasional math blurb for all of the two-and-a-half people that'll read this.

The 3D print lab homepage is the much-anticipated information and landing tab for the covert activities of Lockett 373. On that tab, you can find information about the lab, how to request a print, a gallery of past prints, and a current rough view at our filament inventory. Depending on when you're reading this, there might still be placeholder content on the tab. I'm working very hard (probably) to fix this.

The last new tab is the relevant links tab. It's probably the least special and it just lists the links that used to be scattered around the page. On desktop, the link isn't even shown and the sidebar takes care of showing the extra links.

However, there's more to come. I'll be organizing LSU's DTC seminar in the 2026-2027 academic year. Information on that will eventually have its own tab. I also may or may not be working on some fun and secret projects. Shh!

As a final note, I want to extend my heartfelt congratulations to all of my friends who successfully defended their theses this semester. I will particularly mention my friend Kiri Cahill. Her resilience, kindness, and Tikz ability are constant sources of inspiration and respect for me. Additionally, she managed the 3D print lab with me this past year. Her and her husband Kade have been beyond critical in getting the lab to where it is today.

Best,
Hailey
