Inside Timeline’s Lab: Meet Charlotte Tissot

At Timeline, we’re on a mission to advance human healthspan through science. That work is only possible because of our team of brilliant researchers behind the scenes. In this series, we’re proud to introduce you to the scientists whose passion and expertise fuel everything we do.

Meet Charlotte Tissot, one of our researchers whose work plays a critical role in translating cutting-edge research into meaningful product innovation. From designing cellular models to helping validate the health benefits of Urolithin A, Charlotte’s work sits at the intersection of discovery and real-world impact.

A Lifelong Passion for Science

Charlotte’s path into science started early, and her journey took her through multiple scientific environments before she found her place at Timeline.

I’ve always dreamed of becoming a scientist. When I was eight years old, I wanted to work as a chemist in the cosmetics industry. While waiting for that future to arrive, I used to mix shampoos together, hoping to discover something special, even though I didn’t yet have the knowledge or resources to make that happen.Charlotte Tissot, Research Associate at Timeline

Her true passion for biology emerged a few years later. “During middle school, I had my first biology classes. I was completely fascinated by discovering what happens inside the human body, and I immediately knew this was the field I wanted to pursue,” Charlotte explains. From that moment, she oriented all her studies toward biology and research.

Academic and Industry Foundations

Eager to immerse herself in science, Charlotte left her hometown in the French Alps and moved to Paris, where she earned a bachelor’s degree in pharmacology and cosmetology at Université Paris Descartes. She began her career at Servier, one of France’s leading pharmaceutical companies, working as a research technician focused on metabolic diseases.

There, I saw firsthand how research can have a real and meaningful impact on people’s lives, and I developed a strong sense of the rigor, precision, and responsibility required in the pharmaceutical industry.Charlotte Tissot, Research Associate at Timeline

Continuing to broaden her experience, Charlotte next joined the Institut de Biologie de l’École Normale Supérieure in Paris as an assistant engineer and lab manager in a neuroscience laboratory. She even helped set up that lab from scratch, an incredibly enriching experience that taught her how to build research capabilities from the ground up. Academia allowed her to explore scientific ideas freely, “but over time, I realized that I missed applied research, and my mountains,” she says with a smile. After several years in Paris, Charlotte felt the pull of home and the desire to see her work have a more direct impact on people’s lives.

She decided to return to her hometown near the Swiss border and seek opportunities closer to the Alps and closer to translational science. In the process of searching for a new position, Charlotte discovered Timeline. She was immediately impressed by the company’s scientific publications and clinical studies, particularly those focused on muscle health and aging.

“Seeing how Mitopure® can improve quality of life made me want to be part of this journey and contribute to meaningful, science-driven innovation,” Charlotte says. It was the perfect fit, a chance to work on applied science that could tangibly improve health, all while being near the mountains she loves. “Today, I have the privilege of working at the intersection of my lifelong passions: impactful biology, cosmetology, and the mountains,” she says.

Bringing Scientific Ideas to Life

In her role at Timeline, Charlotte focuses on turning scientific ideas into experiments that can prove real biological impact. “I bring scientific ideas to life by translating research hypotheses into robust in vitro experimental strategies,” she explains.

Charlotte’s role is especially important when exploring a new product concept. Each big idea must first become a testable scientific question.

When evaluating a new product concept, my role is to transform an initial idea into a rigorous in vitro research strategy. I begin with a critical review of the scientific literature to identify the most relevant cellular systems and biomarkers to demonstrate efficacy. I then assess experimental feasibility, design the study framework, and generate data to support scientific conclusions.Charlotte Tissot, Research Associate at Timeline

This process often requires patience and constant refinement. Charlotte notes that bringing a hypothesis from idea to reliable data is rarely straightforward. “This work requires extensive optimization, patience, and problem-solving to ensure that the experiments are both reliable and biologically meaningful,” she emphasizes. Through this iterative, detail-oriented approach, Charlotte helps ensure that Timeline’s new product concepts are backed by solid scientific evidence from the very start.

Why Urolithin A Stands Out

With longevity now a hot topic in science and popular culture, it seems a new “longevity molecule” is in the headlines every day. Charlotte is quick to point out why Urolithin A, the active compound in Mitopure, stands apart from the rest. It all comes down to the mitochondria.

“What fascinates me most about mitochondria is that they are not just the cell’s energy producers; they are key regulators of many essential processes in the body,” she explains. “Mitochondria influence muscle function, metabolism, inflammation, cellular aging, heart health, and how our cells adapt to stress over time. Because they sit at the center of so many biological pathways, when mitochondria become damaged and accumulate with age, their dysfunction contributes to a wide range of age-related declines.” In other words, mitochondrial health is central to almost every aspect of how our bodies function and age.

“Overall, what surprises me most is how a single compound, by targeting a fundamental process like mitochondrial health, can have such broad and interconnected effects across the body,” Charlotte says.

Exploring New Frontiers: Brain Health

While Urolithin A’s benefits for muscle and skin are well established, Charlotte sees new areas of discovery on the horizon. She believes one of the next exciting frontiers for Urolithin A will be brain health.

Emerging research in this area is fascinating. Preclinical studies suggest that Urolithin A may influence brain function by supporting mitochondrial health and synaptic activity, and some animal studies have shown reductions in anxiety-like behaviors.Charlotte Tissot, Research Associate at Timeline

“Although this research is still at an early stage,” she says, “it opens promising perspectives on how improving mitochondrial quality could impact not only physical performance and longevity, but also mental well-being.” In the coming years, exploring Urolithin A’s impact on cognitive function and neuronal health could add a new dimension to how we think about longevity, not just living longer, but living sharper and more mentally resilient as we age.

A Life of Science, Mountains, and Balance

Charlotte’s approach to longevity and wellness in her own life mirrors her scientific mindset: balanced, practical, and sustainable. “I try to approach longevity in a realistic and balanced way,” she says. “I make an effort to stay active by running twice a week and walking as much as possible. I’m also mindful of what I eat, focusing on whole, minimally processed foods.” She supports her health from the inside by taking Mitopure daily, giving her mitochondria a little extra boost. Charlotte also pays close attention to skin health with a consistent skincare routine, including Timeline’s own exfoliator and serum, which she notes “work well for my sensitive skin.”

Outside the lab, Charlotte makes the most of her alpine surroundings and prioritizes time with loved ones. “I’m not sure which came first, skiing or science, but they are both true passions of mine,” she laughs. “On any sunny winter weekend, you’ll find me skiing in the French Alps. During the week, I go running along the lake with Mont Blanc in the background; it’s an incredible setting.” When summer arrives, she trades ski boots for a paddleboard or a bicycle, enjoying the lake and mountain trails.

Just as important, Charlotte cherishes her family and friends. “My friends and family are a real priority, and I love spending time with them, whether that means traveling, going out dancing, celebrating, or simply enjoying life together,” she says. These moments of connection keep her grounded. “For me, the mountains are an amazing playground, but sharing good moments with the people I love is just as essential.” It’s a philosophy of balance: pursuing her passions in nature, sustaining her health with daily habits, and savoring the joy of community.
