Google Maps screenshot showing several miles of the Mississippi–Louisiana border as a dotted line. The line mostly conforms to the river, but contains oxbow shapes that reflect long-gone changes in the River's flow
A map of Spain showing its autonomous communities, which are its first level of regional administration. Ceuta and Melilla, two Spanish exclaves that in the region of North Africa otherwise controlled by Morocco and are in the news, appear as islands instead of parts of North Africa, since the map does not shade in or draw borders for anything not owned by Spain.
Photo of me standing next to my poster at a research conference.
A plot showing the flow of metagenetic material in patients receiving fecal microbiota transplantation. Thick, colorful bands connect a column of donor patients on the left to a column of recipient patients on the right.
A figure panel showing a sketch of how, due to genetic linkage, SNPs are distinguished from RNA editing sites by sharing more mutual information.
Panel of figure 2 of Choquet et al. 2023 "Pre-mRNA splicing order is predetermined and maintains splicing fidelity across multi-intronic transcripts" (Nat. Struct. Mol. Biol.) that uses zig-zagging lines of different thicknesses and (gray) colors to show frequencies of permutations of splicing order of four introns in a representative transcript.
Picture from the Walters Museum of Art of their ~foot-tall bronze statue of the Celtic/Gallo-Roman deity Sucellus, standing in contraposto and holding up a mallet that has been lost to time. Floating behind him is a large mallet with five smaller mallets protruding from its head.
An image of Mithrun, an anime character from Dungeon Meshi, photoshopped to be decked out in Maryland gear and hanging out in Baltimore's Innher Harbor. She is non-chalant, but conveys great pride in her state.
Group photo of the Johns Hopkins University quizbowl team, shortly before round 1 of NAQT's 2025 Intercollegiate Championship Tournament. We are (mostly) wearing matching navy team sweaters. We sit in a large hotel convention space.
A promotional image of MacGyver, looking cool and carrying a missile, for the original '80s TV series.
Figure 1 from Matharu and Ahituv 2015 "Minor Loops in Major Folds" shows (A) a cartoon of chromatin in the nucleus partitioned into differently colored topologically associating domains (TADs), (B) a cartoon of an individual TAD's structure and interactions with the nuclear membrane, and (C) a genetic track displaying regulatory elements, genes, and TAD boundaries within a single (active) TAD compartment, highlighted with a green triangle evocative of HiC heatmap output.
Excerpt from Fig. 2a of Sibley et al. 2016's "Lessons from non-canonical splicing" that illustrates the signature "sawtooth" pattern of RNA-seq read coverage in recursively spliced introns.
A complicated, multi-colored, rectangular visualization of eras of geologic time from the Wikipedia page for the Precambrian. The vertical axis shows time in millions of years ago, and the horizontal axis shows increasing precision of terms in the hierarchy of geologic eras, epochs, eons, whatever, etc.
3D structure of the Drosophila melanogaster protein RH2, a G-protein coupled receptor homologous to human rhodopsin. As a GPCR, it features seven alpha-helical transmembrane domains; one of them is highlighted.
A dense blue scatterplot of putative introns' lengths versus the count of aligned reads that were spliced over them. A red quadratic regression curve fits poorly, interestingly plunging down below the (positive-valued) y-axis between ~7500 and ~20000 bp in length due to the curve being fit to non-log-transformed data, but then displayed with a log-transformed y-axis.
A graph illustrates the formation of a heterotrimer. The reaction network is parameterized by two stage-specific, rate constants, k_dim and k_tri.
