Grace A Cheney
Clinical Assistant Professor, Psychiatry and Behavioral Sciences
BioGrace Cheney, M.D. specializes in the assessment and treatment of ADHD across the lifespan. She serves as Director of the Adult ADHD Assessment Clinic at Stanford, which provides structured, developmentally informed evaluations for adults with attention and executive function challenges. Rooted in a neurodiversity-affirming framework, the clinic focuses on diagnostic clarity to support tailored, evidence-based care. As part of this model, the clinic incorporates the California ADHD Symptom Tracking (CAST) initiative, a semi-structured symptom-tracking method that fosters patient insight, supports individualized treatment planning, and promotes adherence. Through continued collaboration with Dr. Aaron Winkler, creator of CAST and the clinic’s founding director, Dr. Cheney is advancing the use of CAST to strengthen the quality of ADHD assessment and care worldwide.
With subspecialty training in both child and adolescent psychiatry and forensic psychiatry, Dr. Cheney’s diagnostic lens emphasizes precision and developmental context. She has particular expertise in the assessment of ADHD in women, transitional-age youth, and high-functioning professionals. Her treatment approach is comprehensive, and emphasizes establishing foundational non-pharmacological strategies in addition to pharmacological interventions.
Dr. Cheney lectures in the Forensic Psychiatry Fellowship on civil and child forensic topics, and she also supervises psychiatry residents and fellows in adult ADHD assessment. Her emerging areas of interest include the ethical use of AI to maintain therapeutic momentum and accelerate growth between visits, while enriching clinical decision-making with dynamic data that supports more personalized, precise, and adaptive therapy. -
Alan G. Cheng, MD
Edward C. and Amy H. Sewall Professor in the School of Medicine, Professor of Otolaryngology - Head & Neck Surgery (OHNS) and, by courtesy, of Pediatrics
Current Research and Scholarly InterestsActive Wnt signaling maintains somatic stem cells in many organ systems. Using Wnt target genes as markers, we have characterized distinct cell populations with stem cell behavior in the inner ear, an organ thought to be terminally differentiated. Ongoing work focuses on delineating the developing significance of these putative stem/progenitor cells and their behavior after damage.

Paul Cheng MD PhD
Assistant Professor of Medicine (Cardiovascular Medicine)
BioDr. Cheng is a Cardiologist at Stanford University School of Medicine in the Department of Medicine and a member of the Cardiovascular Research Institute. Dr. Cheng received his BEng in Chemical Engineering and BSc in biology at MIT. He subsequently completed his MD/PhD at UCSF working in the Srivastava lab studying how extracellular morphogenic signals affect cardiac development and fate determination of cardiac progenitors. Dr. Cheng completed internal medicine residency and cardiology fellowship at Stanford, including a post-doctoral training in the Quertermous lab. His current clinical focus is in amyloidosis and cardio-oncology.
Dr. Cheng pioneered the application of single cell transcriptomic and epigenetic techniques to study human vascular diseases including atherosclerosis and aneurysm, and applied these techniques to investigate molecular mechanisms behind genetic risk factors for several human vascular diseases including atherosclerosis, and aortopathies such as Marfan's and Loey-Dietz syndrome. The Cheng lab takes a patient-to-bench-to-bedside approach to science. The lab focuses on elucidating new pathogenic mechanisms of human vascular diseases through combing human genetics and primary vascular disease tissues, with high-resolution transcriptomic and epigenetic profiling to generate novel hypothesis that are then tested in a variety of in vitro and in vivo models. The lab is focused on two broad questions: (1) understanding the biological underpinning of the differences in diseases propensities of different arterial segments in an individual (i.e. why do you have atherosclerosis and aneurysms in certain segments but not others), and (2) understanding the role of perivascular fibroblast in human vascular diseases.
