Chat with Greg Fridman

Bioengineering is full of oversimplifications. In this episode, I break down common myths that show up in research papers, startups, and even academic labs: • “More power = more effect” • “In vitro results translate directly to patients” • “Reactive species are always harmful” • “If it works once, it scales” • “Plasma is just oxidation” We’ll talk about dose-response behavior, mechanistic rigor, n...

Most technologies don’t fail in the lab. They fail in the messy middle — between promising data and a working prototype. In this episode, I talk about: • Why elegant theory breaks under engineering constraints • The first prototype shock • Thermal, electrical, and materials challenges • The TRL funding gap • Iteration discipline and kill criteria • When to pivot vs when to persist Having spent ove...

Reactive Oxygen and Nitrogen Species (RONS) are central to plasma medicine, sterilization science, and environmental remediation. But what are they really? In this episode, I break down: • What makes a species “reactive” • The major oxygen and nitrogen radicals • How atmospheric pressure plasma generates them • Why lifetimes and dose matter • Measurement challenges and common misconceptions • Wher...

In this chat, I answer 4 big questions about plasma physics inspired by a thoughtful viewer comment: 1. Should plasma appear on phase diagrams? 2. Does plasma move like a gas — or something else entirely? 3. What elements and compounds are most interesting to turn into plasma? 4. Are transient luminous events like sprites and blue jets scientifically important? Plasma is often called the fourth st...

How does science really get funded in the United States? In this episode, I break down: • How federal agencies allocate research funding • What reviewers actually look for • The difference between academic and industry incentives • Why “high-risk, high-reward” is more nuanced than it sounds • How funding shapes the direction of scientific research Having spent over a decade as a research professor...

PFAS are often called “forever chemicals.” But what does that really mean? In this episode, I break down PFAS from an engineering perspective: • Why carbon-fluorine bonds are so difficult to break • The difference between removal and destruction • Why filtration is not the same as elimination • What incineration, electrochemistry, and plasma actually do • Where the real technical challenges lie Th...

I get asked this a lot: "Greg, with your background, why didn't you just go to Medical School?" In this video, I’m sharing the personal reason I chose the lab over the clinic. It comes down to one thing: Scale. I wanted to build the technologies that would empower doctors to heal things we previously thought were "unhealable." If you’re a student or just curious about the path of a scientist, this...

Plasma isn’t just for rockets or fusion research — it’s used to treat fabrics for clothing every day. In this episode, I explain how atmospheric pressure non-thermal plasma modifies textile fibers at the nanometer scale to improve dyeing, adhesion, antimicrobial performance, and moisture wicking — all without heat damage or chemical baths. We cover: • Surface activation • Nano-scale etching • Func...

What if the secret to safer, fresher food wasn't a new chemical, but just a different kind of water?

We see plasma weapons everywhere in gaming—especially in the Final Fantasy universe—but how would they work in our world? In this video, we analyze the energy requirements, magnetic containment, and heat management needed to turn the 4th state of matter into a tactical tool.

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 ph...

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.

Let's talk about what happens to us when antibiotics stop working...

I’m Greg Fridman, a PhD in Bioengineering. For a long time, I’ve used this channel to review technical papers. Today, I’m changing things up. I’m moving away from formal reviews to have a direct chat with you about the things that actually matter: the future of biotech, the fascinating physics of non-equilibrium plasmas (essentially "cold lightning"), and the unfiltered reality of life in science....
