CV
Here is my CV.
Colophon
This site is made with Quarto and hosted on Netlify. The light theme is cosmo. The dark theme is slate. Feel free to learn from the source code, but please be kind; don’t copy wholesale. Much of my inspiration comes from Silvia Canelón.
Body text is set in Charter, an excellent and modern alternative to Times New Roman. Title text is set in Inter, with tighter font tracking via
h1, h2, h3, h4, h5, h6 {
letter-spacing: -0.2em;
}
to provide a polished look. I mostly follow Matthew Butterick’s excellent Typography in Ten Minutes.
