Ryan Keenan, OD
Clinical Assistant Professor, Ophthalmology
BioDr. Keenan is a board-certified optometrist with the Stanford Health Care Byers Eye Institute and a clinical assistant professor in the Department of Ophthalmology.
Dr. Keenan diagnoses and treats a wide range of ocular and visual issues, such as vision problems related to stroke, intracranial lesions and tumors, and other neurological conditions. His clinical experience involves recognizing and caring for complex neuro-ophthalmic diseases. These include complications from diseases of the nervous system that adversely affect vision.
Dr. Keenan’s research interests include understanding genetic variations related to progressive weakness of the eye muscles. These conditions range from drooping eyelids to increasing limitations in eye movement.
Dr. Keenan has presented research and clinical findings to his peers at national and regional meetings, including the annual meetings of the American Academy of Optometry and the North American Neuro-Ophthalmology Society. -
Kevin R Keet
Clinical Assistant Professor, Medicine
BioDr. Keet is an award-winning medical educator and hospitalist at the Palo Alto VA and Stanford University Hospitals, where he serves as Associate Program Director for the Internal Medicine residency. His clinical practice is grounded in a commitment to empathetic, patient-centered care, and he brings that same orientation to his work with trainees, helping residents develop the clinical reasoning and humanism that define excellent internists. His scholarly interests sit at the intersection of medical education and artificial intelligence, with a particular focus on how physicians can be prepared to use AI tools thoughtfully while preserving the cognitive skills and human judgment that patients depend on.

Preston Kellenberger
Ph.D. Student in Biochemistry, admitted Autumn 2025
BioI was raised in Saint Louis County, MO and completed my undergraduate degree in Biochemistry at The University of Missouri – Columbia. I’m most excited by translational problems that can be addressed through the structural understanding and engineering of biological molecules. At Stanford, I look forward to joining a collaborative community that spans broad scientific disciplines, and to contributing to research that advances human health. I love spending my extra time playing the drums, and I have served as a snare drummer for the world-class Madison Scouts and Cavaliers drum corps.

Corey Keller, MD, PhD
Associate Professor of Psychiatry and Behavioral Sciences (Public Mental Health and Population Sciences)
Current Research and Scholarly InterestsThe goal of my lab is to understand the fundamental principles of human brain plasticity and build trans-diagnostic real-time monitoring platforms for personalized neurotherapeutics.
We use an array of neuroscience methods to better understand the basic principles of how to create change in brain circuits. We use this knowledge to develop more effective treatment strategies for depression and other psychiatric disorders. -

Kevin Kelley
Assistant Professor of Psychiatry and Behavioral Sciences (General Psychiatry and Psychology)
BioAs a neuroscientist and psychiatrist, I am motivated by how little we understand about the pathophysiology of psychiatric disorders and hope that further knowledge will help to alleviate the ongoing distress of many of our patients. My research program leverages computational genomics, human brain cellular models, and molecular neuroscience techniques to understand the cellular and molecular mechanisms of human brain development and how dysfunction in these processes lead to psychiatric disorders.

Michael Kelly, MD, MSCI
Clinical Instructor, Orthopaedic Surgery
BioDr. Michael Kelly is a board-certified, fellowship-trained orthopaedic spine surgeon with Stanford Health Care. He is also a professor in the Department of Orthopaedic Surgery, Division of Spine Surgery at Stanford University School of Medicine.
Dr. Kelly is an expert in treating complex spinal deformities in children and adults, performing advanced surgeries and revision procedures to improve pain, movement, and posture. He specializes in managing scoliosis, spondylolisthesis, kyphosis, and other challenging back and neck problems. He has completed multiple fellowships in treating complex deformities, establishing his expertise in performing three-column osteotomy for spinal realignment. Dr. Kelly provides personalized care using the latest, evidence-based approaches to help his patients achieve a better quality of life.
With a master’s degree in clinical research, Dr. Kelly’s clinical care is driven by his extensive research on spinal deformities and innovations in orthopaedic medicine. His research focuses on improving safety, outcomes, and recovery for spinal surgeries, particularly for spinal deformities. Dr. Kelly’s work has helped define normal spinal alignment, improve surgical techniques, and better understand the long-term impacts of spinal deformity surgeries.
As a leader in orthopaedic surgery, Dr. Kelly has published hundreds of articles in peer-reviewed journals, including The New England Journal of Medicine, JAMA Surgery, The Lancet Neurology, and The Journal of Bone and Joint Surgery. He has shared his expertise at renowned international conferences, including annual meetings of the Scoliosis Research Society and the North American Spine Society (NASS). His presentations often discuss complex spinal deformities, spinal surgery techniques, and strategies to optimize patient care.
Dr. Kelly is a member of many professional organizations where he has also held leadership positions, including the Scoliosis Research Society, AO Spine, and the Cervical Spine Research Society. He is one of the few surgeons in the International Spine Study Group, dedicated to adult spinal deformity care, and the Harms Study Group, which focuses on pediatric spinal deformities.
