Alan Adler Global Ophthalmology Professor
BioDr. Jennifer Rose-Nussbaumer is a board-certified ophthalmologist and fellowship-trained cornea specialist at the Byers Eye Institute at Stanford University. Her clinical practice focuses on corneal transplantation, complex cataract surgery, and the treatment of infectious keratitis.
After completing her fellowship in Cornea and External Disease at the University of California, San Francisco (UCSF), Dr. Rose-Nussbaumer joined the faculty there and remained until 2021, when she transitioned to Stanford. What she loves most about medicine is caring for individual patients—building relationships, understanding each person's unique needs, and guiding them through their treatment with compassion and personalized attention.
In addition to her clinical work, Dr. Rose-Nussbaumer is an NIH-funded physician-scientist whose research centers on randomized clinical trials in ophthalmology. Her research is deeply rooted in her clinical practice: she is passionate about identifying the important, unanswered questions that arise while caring for patients, designing rigorous clinical trials to find the answers, and bringing that new knowledge back to the bedside to improve patient care.
She is the Principal Investigator on a UG1 grant supporting the **Descemet Endothelial Thickness Comparison Trial (DETECT)**, a randomized clinical trial comparing ultra-thin DSAEK (UT-DSAEK) to DMEK, and ripasudil to placebo, in patients with endothelial disease such as Fuchs Endothelial Dystrophy. She is also Principal Investigator on the **Steroids and Cross-linking for Ulcer Treatment Trial (SCUT II)**, a randomized clinical trial conducted in collaboration with Aravind Eye Hospital in India and the University of São Paulo, evaluating the benefit of adjunctive topical steroids, corneal crosslinking, and rose bengal photodynamic therapy in the treatment of infectious corneal ulcers.
A native of Northern California, Dr. Rose-Nussbaumer enjoys spending time with her family and their Bernese Mountain Dog, Kenji, exploring the state's natural beauty through hiking and camping.
