BBM 2026 Poster — Osmotic stress response in B. infantis

Typst poster for the Boston Bacterial Meeting. Osmotic stress response in the infant-associated microbe Bifidobacterium longum subsp. infantis — Irem Ozkan, Cassie Potter, Merredith Swanson, Trisha Rahman, Vanja Klepac-Ceraj, Kevin S. Bonham.

48 × 36 in landscape, light "Paper" (modified-Kanagawa) lab theme.

Build

Fonts (IBM Plex Serif / Sans / Mono, OTF) are bundled in fonts/ and must be on Typst's font path:

just build          # -> poster.pdf
# or
typst compile --font-path fonts poster.typ poster.pdf

Requires Typst ≥ 0.14. Packages (peace-of-posters 0.6.0, tiaoma) are fetched from the Typst preview registry on first compile (needs network once).

Layout

Theme	theme.typ — light "Paper" Kanagawa palette, fonts, peace-of-posters theme dict.
Document	poster.typ — page setup, title, intro strip, three columns, conclusions strip, footer band.
Top strip	Background bullets (full width, 3-up).
Col 1	Fig 1 (salt_all-3, growth + transfers).
Col 2	Candidate osmotolerance genes (Table 1) · cross-species kinetics (salt_compare).
Col 3	Undergrad growth assays (undergrads_salt_*) · Aims & experimental approach (exp_outline).
Bottom strip	Conclusions (full width, 2-up).

All figures sit directly on the cream cards (no figure backing boxes). The matplotlib SVGs (salt_all-3, salt_compare) shipped with an opaque white canvas rect; that single background rect is set to fill-opacity="0" in our copies so the plots blend onto the paper (data markers untouched). exp_outline has black text and was authored for a light background, so it needs no special treatment.

Assets

assets/figures/ and assets/logo/ are copied from the grant, lab-meeting talk, and bonhamlab-web. lab-logo-dark.svg is lab-logo.svg with currentColor replaced by the light-theme ink color (#1C1F26) so it shows on the paper background (lab-logo-light.svg, recolored to #E6E2D3, is kept for a dark variant). The footer-right mark is tmc_text.png (transparent Tufts Medical Center wordmark). refs.bib is kept for the record (citations are not rendered on the poster).

Notes

• QR target is https://bonhamlab.bio — update the tiaoma.qrcode(...) URL in the footer band if it should point elsewhere (preprint, project page).
