CIO by day, cybersecurity professor & Forbes Contributor by night, and a firm believer that the best ideas start with good coffee. I’m passionate about using AI, cloud tech, and leveraging system dynamics to make work (and life) a little easier. Outside of work, I’m either reading/writing in some indie coffee house, hiking shady trails along the river, or adding to my ever-growing collection of houseplants. I’m always learning, always leading, and always up for a good book or a new coffee house to explore. #CyberSecurity #systemstheory #hiking #philosophy #actor #improviser #storyteller #coffee house addict 📍Chicago, IL 🦋🥾☕️🎭🤖🪴✍️

@[email protected]Header image is a novelty desk sign that, instead of a name or title, reads "Welcome to the shitshow," nicked from someone here. Avatar is a selfie of me standing up, outside, with a neighborhood of palm trees and stucco houses behind me. I'm wearing light sunglasses, red lipstick, and a sleeveless shirt with a balloon animal print. Not shown: my walker. #IIH #IdiopathicIntracranialHypertension #fibromyalgia #disability #TransRights

I once worked with goats. I moved into tech.This was a mistake.
Expect sheep, wool, and textile history. Also birbs. Infosec on occasion.
I use content warnings for topics and images that can trigger PTSD. I do not use them to shield people ***without*** trauma from experiencing racism, sexism, transphobia, and other forms of discrimination. If you can ignore politics, you’re not likely in need of content warnings for much of anything, really.
Avatar: me holding a baby goat.

"Esistono senza il consenso di nessuno. Sono odiati, braccati e perseguitati. Vivono in silenziosa disperazione tra il sudiciume. E tuttavia sono in grado di mettere in ginocchio intere civiltà. Se sei sporco, insignificante e senza amore, allora i ratti saranno il tuo modello." Banksy
