About Us

Gallformers is the product of curious amateurs becoming obsessed. If you are here then you too have at least been touched, if not bitten, by the gall bug. It grows in you, but it is not a parasite nor an inquiline.

While you are here we hope that we can help you both ID an unknown plant gall as well as to learn about galls. Whether your interests are very casual, you are a burgeoning scientist, or even a full-fledged cecidiologist we strive to provide useful tools.

This site is open source and you can view the all of the code/data and if so inclined even open a pull request on GitHub.

Who We Are

Adam Kranz

Adam is an independent ecologist focused on gall inducing organisms in North America. He co-founded Gallformers.org as a community resource to help naturalists identify gall observations and to collect information on undescribed galls. His primary focus is on adding literature and information to the Gallformers database.

Jeff Clark

Jeff is a Software Engineer who stumbled upon galls and became obsessed. So much so that he co-founded this site, wrote all the code for this site, and is responsible for keeping it going, fixing it, and implementing new features (and is currently the sole financial supporter). If the site is broken, it is most likely his fault.

Yann Kemper

Yann is a 17 year old student from Cincinnati, Ohio. For the past three years he has been an active contributor on iNaturalist, developing a recent interest in galls in the process.

Besides the folks profiled above, others help out by contributing code, data, and feedback to help us improve the site.
