Mark is the Hugo-nominated writer of the online Mark Does Stuff universe (Mark Reads and Mark Watches), where he analyzes book and TV series. He was the nonfiction editor of Queers Destroy Science Fiction! and the co-editor of Speculative Fiction 2015 with Foz Meadows. He is currently the fiction editor for Efniks, an online magazine for queer and trans people of color (if you’re interested in submitting a story, see http://efniks.com/submissions/) and also the President of the Con or Bust Board of Directors. His first novel, Anger is a Gift (AmazonGoodreads), is a YA contemporary about queer friendship, love, and fighting police brutality. It will be released by Tor Teen on May 22, 2018.

You can check out Mark further on PatreonTwitterFacebook, and Instagram. When he is not writing, crying on camera about fictional characters, or ruining lives at conventions, he is busy trying to fulfill his lifelong goal: to pet every dog in the world.


Johnny is a Security Researcher at Uptake, a company dedicated to ensuring safety, reliability, and security of  industrial environments.  Johnny’s been speaking internationally (both in and very far outside of the infosec community) on the topics of information security, career advancement, and social engineering for nearly 20 years. His infamous mixture of humor, raw sincerity, and honest love of people often leads to a lighthearted, but (at its core) serious, discussion around our innate desires to get in our own way.

Recently, he was one of the masterminds behind the reproduction and leaking of the TSA Master Keys from 2016-present (with a final 006 in the works). The purpose of this was to help educate the public on the dangers of rotationless key escrow, such as that which the government is requesting for all of our digital communications.

You can check out Johnny further on Twitter and YouTube.


Kristine is Professor of Astronomy at Central Connecticut State University in New Britain, Connecticut. Her teaching and research focuses on the intersections of science and society, including the history of women in science, and science and popular culture.

In particular, her work focuses on depictions of science and scientists in the works of J.R.R. Tolkien (Perilous and Fair: Women in the Works and Life of J. R. R. Tolkien), Neil Gaiman (The Mythological Dimensions of Neil Gaiman), Andrzej Sapkowski, Phillip Pullman, and George R.R. Martin (among others). She has also examined film and television series (especially Doctor Who—The Mythological Dimensions of Doctor Whoand zombie media). She is also the author of Stephen Hawking: A Biography, The Women Who Popularized Geology in the 19th Century, and Cosmology 101.

Kristine is also the president of the American Association of Variable Star Observers, and shares her home with assorted misfit cats and rabbits.


An interface designer, Christine (per her Twitter bio) builds things. The things she builds vary, but her focus throughout it all is on interfaces hooking into human behavior and expectation. She believes the level of complexity in tactility, geometry, and human factors in connected interface design requires understanding and experience with people and interfaces from non-digital fields. Her multidisciplinary experience with the digital, physical, and human allows her to create effective and successful experiences for users.

Christine has implemented developer experiences and run IoT workshops, designed interfaces for patient motivation in high-stakes settings, made trending content on electronics, and created hardware and software for research in bleeding-edge fields. She started and runs HackPretty (read more about why she started HackPretty), built robots at BuzzFeedrun hackathons at Particle, just finished up Everyday Bots on The Verge (this was her favorite hack), and spoken at TEDx and Hackaday about the weird psychological line between alive and not-alive in technology.
