Letters of Recommendation

If you're reading this page, it's because you've asked me (or are thinking of asking me) to write you a letter of recommendation.

I'm happy to provide letters where they can be helpful. However, I also want to be transparent about what kinds of letters I'm able to write and where I'm comfortable submitting them, since different applications have different expectations for letters. Writing a strong letter takes a significant amount of time and effort on my part, but not every program needs a strong letter.

Regardless of what kind of letter you're asking me for, some overall instructions:


Short Letters

Some examples of programs that I am fine writing short letters for include:

A short letter tends to consist of "X took my course and earned [insert grade here]", potentially with some descriptions of our interactions. This type of letter isn't appropriate for all applications, but is certainly acceptable for quite a few.

Once I've agreed to write you a letter (and directed you to this page), send me the following information at least two weeks before the earliest deadline:


Strong Letters

Some examples of applications that I will need to know you better for include:

The students that I can most effectively write a strong letter for include those who have been a teaching assistant or have done research with me in at least two distinct quarters. I may also be able to write these letters if we've had extensive interactions both in and outside of class, and you've gone above and beyond the course requirements; but they won't be as strong as for students with whom I have a strong working relationship.

If you're not sure what kind of letter is right for you, or whether I can write you a strong letter, please ask.
