Thai Researcher's Mars-Inspired Work on Life's Origins Reaches Chemistry Journal Cover
Hydrogen atoms tunneling through barriers that shouldn't exist
Mark
What made The Martian the thing that unlocked this for you? It's just a movie.
Mimi
It gave me permission to think sideways. I was drowning in the technical details—amino acids, peptide bonds, prebiotic conditions. The film asked a bigger question: what if life started somewhere else? That reframed everything. Suddenly I wasn't just solving a chemistry problem. I was investigating a possibility.
Mark
So the quantum tunneling part—that's the thing that surprised you?
Mimi
It surprised everyone. Hydrogen atoms shouldn't be able to pass through those barriers according to classical chemistry. But when you treat them as quantum objects, they can tunnel through. On early Earth, with all that heat and pressure, this might have been happening constantly. It's a pathway that shouldn't exist, but does.
Mark
And now you're thinking about rocks and minerals as factories?
Mimi
Yes. We're asking whether natural surfaces—just the geology of the planet—could have done this work without any biological help. If common materials can catalyze these reactions, it changes how we think about both the origin of life and how we might manufacture complex molecules cheaply today.
Mark
What was it like mentoring John?
Mimi
Watching someone gain confidence through research is different from any other kind of teaching. He built code, tested it, presented it. I saw him transform from uncertain to proud of his work. That's the real value of these exchanges—not just the papers, but the people you help grow.
Mark
Do you think you'll come back?
Mimi
I hope so. The connections here are real. This isn't the end of the work. It's the beginning.
El Pulso
- A young Thai chemist landed in Canada expecting familiar work on catalysis, only to be handed one of science's oldest unsolved puzzles: how did life's molecular machinery assemble itself on a lifeless planet?
- The disorientation was real — until a Hollywood film about a stranded astronaut cracked open her thinking and gave the abstract question a shape she could pursue.
- Working entirely on computers, the team simulated prebiotic Earth conditions and treated hydrogen not as fixed particles but as quantum clouds capable of tunneling through barriers classical chemistry deems impassable.
- The result was a cover paper in Organic & Biomolecular Chemistry, revealing chemical pathways that conventional theory would not predict — and pointing toward cheaper, greener ways to manufacture complex molecules.
- Beyond the science, Pimbaotham mentored an undergraduate coder, presented at national conferences, and became living proof that international research exchanges can reshape careers and sustain collaborations across continents.
Four billion years before the first cell divided, the chemistry of life was already being written in the hostile conditions of a young Earth — and now, a Thai researcher named Pimjai Pimbaotham, working at a Canadian university far from home, has helped decode a fragment of that ancient script. Inspired by a science fiction film and guided by a computational chemist, she used quantum simulations to reveal how amino acids may have bonded into the first proteins without any biology to assist them. Her work, published on the cover of a Royal Society of Chemistry journal, reminds us that the deepest questions about existence are still being answered — and that the people answering them often arrive from unexpected places.
Pimjai Pimbaotham arrived at UBC Okanagan in 2024 expecting to work on catalysis. Instead, her supervisor Dr. Robert Szilagyi handed her a question that felt impossibly vast: how did amino acids — the building blocks of all proteins — bond together four billion years ago, before any biology existed to guide the process? She couldn't find the shape of it, until she watched The Martian. The film's portrait of a scientist reasoning through survival on an alien world unlocked something in her thinking. If life could theoretically emerge elsewhere, what were the actual chemical pathways that might make it possible?
The answer required no laboratory. Pimbaotham and Szilagyi worked computationally, simulating the position of every atom and electron across a range of conditions that would have dominated early Earth — varying acidity, extreme pressure, intense heat. Their key insight was treating hydrogen atoms not as fixed points but as quantum clouds capable of tunneling through barriers that classical chemistry considers impassable. The simulations revealed reaction pathways that conventional theory would not predict, but that may have operated on a primordial planet.
Two years after arriving in Canada, Pimbaotham was first author on a paper that reached the cover of Organic & Biomolecular Chemistry. The research carries practical weight beyond its origins story: it suggests cheaper routes to synthesizing complex molecules using abundant materials, and the team is now exploring whether common mineral surfaces could have served as natural reaction platforms — potentially opening new manufacturing pathways for valuable biological compounds.
Her time in Kelowna also made her a mentor. Undergraduate student John K. Villanueva built part of the quantum computing code the research required, and watching him grow became, she says, one of the best parts of her exchange. The path that brought her to Canada traced its own network of international connections — her Thai thesis advisor had met Szilagyi through a Japanese science program, and a Canada-ASEAN scholarship ultimately made the year possible. For UBC's Go Global office, Pimbaotham's story is a familiar arc: students arrive for research, build relationships, and those relationships often last for years.
Pimjai Pimbaotham arrived at UBC Okanagan in 2024 expecting to continue her work on catalysis, the science of accelerating chemical reactions. Instead, she was handed a problem that felt impossibly abstract: how did the molecular building blocks of life assemble themselves four billion years ago, on a planet with no biology yet to guide the process? The question disoriented her. She couldn't see the shape of it.
Then she watched The Martian. The film follows an astronaut stranded on Mars, studying the planet's soil and environment in a desperate bid to survive. It was fiction, but it cracked something open in her thinking. If life could theoretically emerge elsewhere in the universe, what were the actual chemical pathways that might make it possible? What if she could map them?
Working with Dr. Robert Szilagyi, a computational chemist in UBC Okanagan's Irving K. Barber Faculty of Science, Pimbaotham set out to answer a deceptively simple question: how do amino acids—the building blocks of proteins—bond together? Proteins are the machinery of all living things, chains of amino acids held by peptide bonds. But before any biology existed to assemble them, those bonds had to form on their own, in the hostile chemistry of early Earth.
The team didn't work in a lab. They worked on a computer, simulating the position of every atom and electron at each instant of the reaction. They tested the process under conditions that would have dominated the young planet: different acidity levels, crushing pressure, intense heat. What made their approach distinctive was treating hydrogen atoms not as fixed particles but as quantum clouds capable of tunneling through barriers that classical chemistry says should be impassable. The work revealed pathways that shouldn't exist according to conventional theory—but might have existed on a primordial Earth.
Two years after arriving in Canada, Pimbaotham became first author on a paper that made the cover of Organic & Biomolecular Chemistry, one of the Royal Society of Chemistry's flagship journals. The research does more than satisfy curiosity about life's origins. It points toward practical applications: cheaper ways to synthesize complex molecules using abundant, inexpensive materials. The team is now investigating whether common mineral surfaces and metal-bearing rocks could have served as natural workbenches for these reactions, potentially opening new manufacturing routes for valuable chemicals and biological compounds.
During her time in Szilagyi's lab, Pimbaotham found herself in an unexpected role as mentor. Undergraduate student John K. Villanueva built and tested part of the quantum computing code the peptide research required. Watching him grow in confidence and skill became, she says, one of the best parts of her time in Canada. She presented her work at UBC Okanagan, the Western Canadian Undergraduate Chemistry Conference, and the Canadian Chemistry Conference and Exhibition in Ottawa, alongside graduate and undergraduate researchers from the lab.
Pimbaotham's path to Kelowna was itself a product of international research networks. Her thesis advisor, Dr. Siriporn Jungsuttiwong, had participated in the Sakura Science Program in Japan, where she met Szilagyi. When funding for a year-long exchange proved out of reach, Szilagyi pointed her toward the Canada-ASEAN Scholarships and Educational Exchanges for Development program, designed for Southeast Asian students. A conversation between Pimbaotham, her supervisors in Thailand and Canada, and Dr. Masanori Tachikawa of Yokohama City University led to the research breakthrough.
The Visiting International Research Student program, which enabled Pimbaotham's work, welcomes undergraduate and graduate students from universities worldwide. Participants conduct full-time research under UBC faculty supervision while remaining enrolled at their home institutions, with no requirement to pursue a UBC degree. According to Dr. Dana Lowton, Assistant Director of the UBCO Go Global program, these placements often mark just the beginning. Students arrive for research, build connections, and those relationships frequently continue for years—with many former VIRS participants returning to pursue graduate degrees at UBC.
