text with a picuture of gabreil rabinovich saying "Gabriel Rabinovich, immunologist, tumor biologist, and glycobiologist Writing has played a key role in my career as a researcher. I firmly believe that one does not simply write up results sequentially; instead, one tells a story. I've always enjoyed storytelling. After completing the experiments, I try to craft a narrative that appeals to an interdisciplinary audience, not just to specialists in my field. My goal is always for people from other disciplines to be able to understand my papers. Writing in a linear, step-by-step way can feel monotonous and dull. I try to construct a compelling story. Sometimes, it's not the question I asked at the beginning, but the one that emerges from all the results taken together. This approach has had a big impact on how my papers are received. When editors read something that tackles a meaningful question in the field, they're more likely to be positive with it. Thatβs why I put a lot of effort into the cover letters. Theyβre the first thing editors see, and I structure them point-by-point with clear logic to show that the paper addresses an open question in the literature. "
βYou donβt just write results, you tell a storyβ
Gaby Rabinovich reminds us to write for an interdisciplinary audience, be honest about limits, and keep the big question clear
