Postdoctoral Scholar, Radiation Physics
BioI am currently a Postdoc Fellow in the Department of Radiation Oncology of Stanford University, advised by Prof. Lei Xing. Before joining Stanford, I obtained my Ph.D degree in the Department of Electrical Engineering, City University of Hong Kong, supervised by Prof. Yixuan YUAN, Prof. W.S Tommy Chow, and Prof. L.H. Leanne Chan. I visited Massachusetts General Hospital and Harvard Medical School, supervised by Prof. Xiang Li and Prof. Quanzheng Li. Before that, I received the B. Eng and M. Eng degree from College of Computer Science and Software Engineering in Shenzhen University of China in 2017 and 2020, supervised by Prof. Linlin Shen. From Dec. 2019 to Nov. 2020, I had interned in Tencent Jarvis Lab, supervised by Dr. Shuang Yu and Prof. Yefeng Zheng.
My research interests lie in vision-language model, multi-modal large language model, generative AI, computer vision and their applications on medical AI, with a focus on report generation, medical image synthesis, endoscopy super-resolution, retinal image segmentation, multi-modality diagnosis, etc. -

Yiyun Chen
Postdoctoral Scholar, Stanford Cancer Institute
BioYiyun Chen, Ph.D. is a Postdoctoral Fellow at Professor Crystal Mackall’s group at Stanford Cancer Institute.
Dr. Chen studied biochemistry and structural biology in her undergraduate and master trainings at The Hong Kong University of Science and Technology, where she eventually obtained her Ph.D. degree in computational biology under the supervision of Professor Jiguang Wang. During her Ph.D. training, she has developed her skill sets in analyzing and integrating various types of patient-derived sequencing data, published three first-author and four co-author papers, and received two awards for top postgraduate students. Through interdisciplinary collaborations with cancer biologist and clinicians in US and Asia, her work has uncovered tumor-specific immune cell subtypes and novel noncoding RNAs and generated new insights into precision medicine in glioma, lymphoma and gastric cancer.
Applying her expertise in computational cancer biology and immunology, her current research is focused on identifying molecular mechanisms that contribute to the clinical outcomes of patients undergoing CAR-T immunotherapy. At Mackall Lab, she will contribute to tailoring computational pipelines for profiling the spatiotemporal dynamics of the tumor and immune microenvironment and translate new discoveries into cancer therapeutics. -

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.
