In his graduate school program, Ezira Yimer‘s doctoral work centers on the HT-Evolver, a high-throughput evolution system for cellular and molecular engineering. But his path to this platform wasn’t straightforward. Before landing on tool development, Ezira worked for a startup focused on microbiome therapeutics, and explored ways to evolve receptors to influence the microbiome environment. It was formative undergraduate experiences, however, that pivoted him toward platform development. Through the Technology Inspiration Scholars Program (TISP), he worked with high school students in the Boston area, leading STEM-focused activities and K-12 initiatives. “Learning how people think about science outside of academia is really good for understanding what we actually contribute to the broader world,” Ezira reflects. More significantly, he participated in an International Genetically Engineered Machine (iGEM) project in Professor Doug Densmore’s group. His team recognized the broad utility of microfluidic techniques, but also the acute challenges scientists faced in adopting them. That focus on accessibility—building devices and equipment to lower barriers to entry—became central to how Ezira thinks about research.
“With a more traditional basic biology project, you design experiments that prove or disprove a hypothesis,” Ezira explains. “But with tool development, you’re building something that needs to be reliable, cost-effective, robust, and accessible. If it’s not easy to use, there’s no point—no one will use it.” This engineering mindset—one that prioritizes the end user above all else—has become central to how Ezira approaches his doctoral research. The HT-Evolver work involves inherent biological challenges—managing fluid inputs and outputs for each culture while maintaining sterility and multiplexing across different systems. But Ezira approaches these technical hurdles with an eye toward the end user. He stays engaged with emerging technologies, following papers on “self-driving labs” and automation platforms to see how other researchers tackle similar challenges.
Ezira finds balance through creative pursuits outside of the lab. He cooks after long lab days and brews mead at home—work that scratches an itch he used to satisfy doing yeast work in the lab. There’s something restorative about hands-on creation. This intentionality about life beyond the bench informs his advice to younger students. “It will get difficult at times,” he acknowledges, but “you are not your work. You are an individual outside of the lab.” For undergraduates considering graduate school, his advice is more practical: “Do extracurricular projects. Doing more stuff outside of the classroom is really good and lets you figure out what you like and what you don’t like.”
Looking ahead, Ezira’s professional goals are clear: he wants to continue building automation, hardware, and software for biotech and life sciences in an industry setting. But perhaps most tellingly, Ezira doesn’t envision himself leaving his platform behind. “I don’t foresee myself as a professor, but I would love to continue tinkering and working with HT-Evolver as a developer.” That distinction matters. Ezira isn’t building a tool to move on from—he’s building something he hopes will matter long after he leaves. It’s a philosophy that began early, where he recognized that the best innovations aren’t the ones that sit on a shelf; they’re the ones that lower barriers and invite others in.
