Advising students is one of the most important and fun parts of my job!
I am interested in making academia more welcoming, more open, more transparent, more accessible, and less intimidating.
I am a member of the Math Alliance.

Where can I find resources if I am interested in applied topology?
- You may be interested in the Applied Algebraic Topology Research Network (AATRN). Become a member to receive email invites to the online research seminars. Recorded talks are available at the YouTube Channel.
- Other online research seminars on applied topology include GEOTOP-A: Applications of Geometry and Topology and the Asia Pacific Seminar on Applied Topology and Geometry (APATG).
- An important source of applied topology news is appliedtopology.org. Mailing lists with announcements in applied topology include WinCompTop and ALGTOP-L. You may also be interested in joining the Slack channel "Geometry & Topology in ML".
- See this partial list of applied topology software options.
- See this partial list of applied topology book options.
- Attending talks: Whenever you attend a talk, and especially if you are a student, prepare at least one question that you could possibly ask (this is possible even if you understood only the first sentence of the talk). If nobody else asks a question at the end of the talk, then you are required to ask your question! The speaker and the seminar organizer will both greatly appreciate it. Half of the questions I try to ask are misinterpreted to be more interesting than I intended them to be. If there's not time to ask your question after the talk, you now have a question prepared if the speaker sits next to you at lunch. Asking a question is a great way to meet people!
- Letters: Here are instructions if I am writing a letter of recommendation for you.
- Grading: Here are my tips for serving as a grader for one of my classes.
- LaTeX: Here is a LaTeX template for beginning LaTeX users. For more advanced LaTeX users, here are some LaTeX guidelines that I generally follow.
- Overleaf: Here are my tips for using git with Overleaf. Please email Henry if you'd like a link that will allow you to clone and play with this practice repository. UPDATE: It turns out that using git with Overleaf for free is only possible if you were grandfathered in as an Overleaf v1 user.
- High school math: Here is a list of mathematics opportunities for advanced high school (or middle school) students, primarily in Colorado.
- Conferences: It's important for students to keep their eyes open for conferences they want to attend, for example by subscribing to the WinCompTop and ALGTOP-L mailing linsts. A good place to look for conferences is at the math institutes, such as the following, where you are often able to apply for travel funding: ICERM, MSRI, IMA, IPAM, Mathematical Problems in Industry (MPI) Workshop. For folks two years prior through 5 years after receiving their PhD, I highly recommend the MRC program, which is a great way to meet new folks in your research area, start a new research area, obtain funding for follow-up collaboration travel, and to travel to the Joint Meetings the following year.
- arXiv: Here are my tips for posting a paper to arXiv.
- MSC codes: Here are my tips for choosing MSC codes for a paper with me!
- CSU thesis formatting: The webpage on formatting your CSU thesis contains a link to a semi-official LaTeX thesis template, which several of my students have used.
- Sharing your thesis with your committee: One optional trick is that when you share your thesis with your committee, don't send them a PDF. Instead, email them a link to your thesis posted on your webpage. This allows you to make tiny changes and your committee "automatically" has the most up-to-date version (depending on how long they procrastinate their reading). Even if you don't make any changes then you're no worse off!
- Applying for academic jobs after your PhD: Here are some sample materials for applying to academic jobs after your PhD.
- Giving talks: Here are my tips for giving a math talk.
- Moderating talks: Here are my ``minutes remaining" signs. Print them dual sided; that way you can tell speakers that when you hold up the sign, they will know how many minutes they have left, and also the audience will know how many minutes they have left! Hopefully that will keep the speakers honest :).
- Women in math: See Lara Kassab's collection of resources for women in math and related disciplines.
- Applied topology software: See this partial list of applied topology software options.
- Online instruction: See my current thoughts and plans for online instruction. In particular, I explain how to make screen-capture videos of class content, along with an inset talking head.
- How to develop an online research seminar: I wrote an article How do I ... develop an online research seminar? for the September 2020 issue of the Notices of the American Mathematical Society. See this list of online math seminars that I currently know about.
