What Marine Microbiology Taught Me About Writing Fiction

People are always surprised when I tell them I spent twenty years studying microbes before I started writing novels.

"That's so different!" they say. "Science and creative writing are completely opposite."

Are they, though?

Because the more I work on this novel, the more I realize that marine microbiology was actually excellent training for fiction writing. Not in spite of being science, but because of it.

Lesson 1: Pay attention to what's invisible

Microbes are everywhere and nowhere. You can't see them. Most people don't think about them. But they run the planet.

They drive nutrient cycles, regulate atmospheric chemistry, form the base of marine food webs, and basically keep Earth habitable. If you want to understand ocean ecosystems, you can't just look at the charismatic megafauna—the whales and dolphins everyone cares about. You have to understand the invisible stuff underneath.

Fiction works the same way.

The most important things in a story are often invisible: subtext, motivation, the history between characters that never gets stated directly, the world-building that supports the plot but never makes it onto the page. If you only write what's visible on the surface, you end up with something hollow.

My years of training myself to pay attention to the invisible, the microscopic, the stuff everyone else ignores? Turns out that's exactly what you need to write layered fiction.

Lesson 2: Everything connects to everything

In marine ecosystems, you can't change one thing without affecting everything else. Increase temperature by two degrees? Okay, now you've altered microbial metabolism, changed nutrient cycling rates, affected phytoplankton communities, shifted food web dynamics, and modified ocean chemistry.

Pull on one thread and the whole system responds.

Plot works the same way.

If your character makes a decision in chapter three, it can't just disappear by chapter seven. If you establish a geopolitical conflict in the opening, it has to ripple through the rest of the story. If you introduce a technology, you have to think through its second-order and third-order effects.

Writing a novel about geoengineering basically requires me to be an ecologist of imaginary systems. What are the cascading effects? What feedback loops emerge? Who benefits and who suffers? What unintended consequences show up three moves down the line?

I spent two decades training my brain to think this way about real systems. Now I do it with fictional ones.

Lesson 3: You can't rush understanding

Marine microbiology taught me patience. You can't speed up a microbial culture. You can't rush the data collection. You wait for the field season. You wait for the samples. You wait for the sequencing results. You troubleshoot. You revise your hypothesis. You run the experiment again.

Fiction is the same—just slower.

I've been working on this novel for a decade. There have been times when that felt like failure, like I should be able to just write the damn thing already. But here's what I learned from science: complex systems take time to understand. You can't rush mastery.

Every writing class I took, every workshop, every time I walked away from the manuscript and came back—that was all part of the process. Not wasted time. Not failure. Just the work of understanding a complex system (in this case, a story) well enough to get it right.

Lesson 4: Specificity matters

In marine microbiology, precision is everything. You don't say "some bacteria." You identify the genus, the species, the strain if you can. You measure temperature to the tenth of a degree. You note the exact salinity, the precise depth, the specific coordinates.

Because details matter. The difference between 28°C and 30°C seawater is the difference between a thriving coral reef and a bleaching event.

Fiction needs that same specificity.

Not "a tree"—what kind of tree? Not "she felt sad"—what kind of sad? Not "the city was crowded"—show me three specific details that make me feel the crowd without using the word "crowded."

The best fiction is precise. My science training gave me that instinct—the reflex to ask "be more specific" until the truth emerges.

The unexpected gift

I used to think switching from science to fiction was a major career pivot—that I was leaving one world for another.

But the more I write, the more I realize I'm using the same skills. Observation. Systems thinking. Patience. Precision. Comfort with complexity. The ability to zoom in on the microscopic detail and zoom out to see the whole system.

Marine microbiology wasn't a detour from writing fiction.

It was training for it.
