“Ri brought exceptional rigor and structure to complex assignments such as literature evaluation and CER development to our team.

She was highly skilled at identifying pertinent, regulatory-grade evidence, applying epidemiological principles and statistical reasoning to distinguish high-quality studies. Her assessments of clinical outcomes and safety data were consistently balanced, critical, and well aligned with current regulatory expectations and guidelines. She worked independently through challenging regulatory reviews and demonstrated a high level of scientific integrity, precision in data verification, and clarity in communicating her reasoning during cross-functional collaboration.

I am confident that Ri will bring significant value to scientific and regulatory writing initiatives and will continue to grow and contribute meaningfully in high-standards environments."

"Ri Xu is an exceptional medical writer known for her rigor, curiosity, and reliability.

She consistently delivers high-quality drafts and revisions, from synthesizing state-of-the-art evidence to addressing complex regulatory feedback with precision.

Beyond strong execution, Ri continuously looks for ways to improve the writing process itself. Her research depth, attention to detail, and ability to streamline workflows through thoughtful automation make her particularly well suited for research- and regulation-focused projects.

With a strong engineering mindset and forward-looking approach, Ri consistently goes beyond expectations and delivers work that is both efficient and high-impact."

"Ri is an interdisciplinary grant writer that will grasp problems quickly and help you propose solutions that make sense to both reviewers and innovators.

Her critical thinking and attention to detail allow her to use AI fluently yet reliably in domains outside her immediate expertise effectively. She leverages AI for rigorous fact-checking and refining technical claims, preserving scientific credibility and nuance. She pinpoints what’s holding the project back and works with clients to chart a practical funding path.
What stood out was her ability to build a device or method from the ground up, thinking through each component with an engineer’s mindset. She uses literature strategically to demonstrate feasibility and writes clear, concrete impact statements, bringing strong structure and coherence to every proposal."
