Mattias Adolfsson (cover and “Microbial Social Network") is a freelance illustrator operating from Sigtuna, outside Stockholm, Sweden. In addition to sketching bacteria and viruses, he makes other commissioned works but always finds time for moderate walks in the forest and personal drawings.
Sarah C.P. Williams (“Microbial Social Network”) can’t seem to cut her ties to HHMI. She’s been associated with the Institute first as a budding scientist, then as a staff member of the Bulletin, and now as a freelance writer. Though she grew up in New England, today she makes her home near the shores of Hawaii, where she enjoys kayaking and traipsing up mountains with her husband and dogs.
Scottish-born photographer Graham MacIndoe (“Driven") lives and works out of New York City. He shoots for editorial, corporate, and advertising clients, including The New York Times Magazine, The Guardian Magazine, and W magazine, among others. Current personal projects include one about addiction and recovery and another on immigration detention in the United States.
Al Murphy (“Intoxicating Research”) is a British illustrator who loves to draw freehand. When not busy adding faces to inanimate objects, he is busy worrying how long it will be before he has to get a real job. He makes his home in Brooklyn, NY, with his partner Annie and their son Casper.
