We are Anna and Tod. Together we write as A. Kristina Casasent. When not writing we serve the whims of our Newfoundland dog, two cats, and a Crested Gecko. Living in Texas, we work in the sciences by day and write fiction by night.

The two of us write across a selection of genres, usually with a slight touch of humor, including science-fiction, fantasy, and thriller/horror. More about this on Our Universes page.

If any of it sounds interesting don't forget to check our Amazon Author's⇗ page.

Anna has a PhD in biomedical sciences and a background as a bioinformatician. She is an avid dog (and cat) trainer and is the driving force behind A. Kristina Casasent.

Tod is a software developer and has worked in a variety of industries. He learned to fly the space shuttle in on-orbit rendezvous and docking maneuvers and how to keep the space station thermal bus from self-destructing. Anna turned him into a writer.

On our SubStack blog⇗, we write about dog training, animal behavior, as well as about cooking and recipes (often Paleo, sometimes lactose free, and always gluten free). Random science facts can occur at any moment.
