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 🦋🥾☕️🎭🤖🪴✍️

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.
