Why did you choose the Clinical Research industry?
I chose to work in clinical research because I wanted to be part of something meaningful. It’s not just about working with numbers or writing reports—it’s about helping people. Every clinical trial we support could lead to a new treatment that gives hope to patients. We help doctors and healthcare teams by giving them accurate, science-based information they can trust. And we play a role in improving public health by making sure new medicines are safe and effective. Knowing that my work can touch lives—even if it’s behind the scenes—is what motivates me every day
What does a day in the life of a Principal Medical Writer look like?
My day as a medical writer is a mix of quiet writing time and busy teamwork. I usually start with a cup of coffee and check my emails and deadlines. Then I get into writing—this could be a report, reviewing project timelines, or slides for a presentation. I spend a lot of time turning complicated medical data into clear, easy-to-understand content. I look through research papers, trial results, and guidelines to make sure everything is correct. In the afternoon, I usually have meetings with medical experts, reviewers, or other writers to talk through the data and make sure we are all on the same page. There is always something new to learn, which keeps things interesting. By the end of the day, I’m finishing up edits, checking references, and getting ready for the next round of work.Explore Parexel
