What is plasma? Most people think of blood or TV screens, but in physics, plasma is a high-energy "soup" of charged particles. From lightning bolts to the surface of the Sun, we explore the science behind the most common state of matter in the cosmos.

I recently had the opportunity to speak with three cohorts of seniors at Bexley High School in Columbus, OH, about my journey in plasma physics and engineering. While we talked a lot about science, the most important part of the day was sharing the "human" side of a technical career.

What if I told you there’s a molecule inside you right now acting as a microscopic assassin? In this video, we explore the strange world of Peroxynitrite.

Tired of harsh chemicals and endless plastic bottles in your skincare routine?

What if we could treat cancer without the "sledgehammer" approach of traditional chemotherapy?

What if we could test a new drug on a human heart or lung without ever putting a patient at risk?

Imagine a wound that hasn't healed for months, or even years. For millions of people dealing with chronic ulcers and "superbug" infections, this is a daily reality. In this chat, I’m breaking down why some wounds simply refuse to close and how we’re using non-equilibrium plasma (what I call "cold lightning") to fix them. We’re moving beyond traditional bandages and antibiotics to a future where physics does the healing. No jargon, no gatekeeping—just the science of how we’re solving one of medicine's most stubborn challenges. Have a question about plasma medicine or the future of healing? Let’s talk in the comments.

I recently received a great question from a viewer about how studying non-equilibrium plasmas—what I call "cold lightning"—changes the way I look at the world.
