Ash A. Alizadeh (born Arash Alizadeh) is an Iranian-American physician-scientist and professor of medicine at Stanford University School of Medicine in the Division of Oncology.[1] His research focuses on cancer genomic technologies and development of liquid biopsy methods such as CAPP-Seq, as well as the genomic and immunologic mechanisms driving lymphoid malignancies, and computational approaches for characterizing tumor microenvironments.[2] Alizadeh is recognized for developing the Lymphochip microarray and for his early cancer molecular taxonomy work defining the molecular subtypes of diffuse large B-cell lymphoma (DLBCL), which transformed lymphoma classification and clinical management.[3]

According to Google Scholar, he has 96,975 citations, an h-index of 103, and an i10-index of 213.[3]

Education and training

Alizadeh earned his Bachelor of Science in Biochemistry with honors from the University of California, Los Angeles in 1994. He completed the NIH-funded Medical Scientist Training Program (MSTP) at Stanford University School of Medicine, receiving his M.D. in 2003 and Ph.D. in Biophysics in 2001.[4]

He completed his residency in internal medicine through the Clinical Investigator Pathway at Stanford Hospital (2004–2006), followed by a fellowship in hematology and oncology (2006–2009) under Sandra Horning.[3] From 2007 to 2010, he held a postdoctoral fellowship at Stanford in investigative hematology with Irving Weissman and Ronald Levy.[5]

Academic career

Alizadeh joined the Stanford University faculty in 2009 as an Assistant Professor and became a full professor in 2021. He is the Moghadam Family Professor of Medicine (Oncology) in the Stanford Cancer Institute and directs the Alizadeh Laboratory at Stanford.[6] His group studies tumor heterogeneity, immune–tumor interactions, and circulating tumor DNA (ctDNA) dynamics in lymphoma and solid cancers.[7][8]

Alizadeh is a co-founder of CAPP Medical, a cancer diagnostics company that was later acquired by Roche, as well as CiberMed.[4] He has also contributed to the founding of Foresight Diagnostics, which was subsequently acquired by Natera, and Resero Bio.[9] His U.S. patents include “Systems and methods for analyzing mixed cell populations” (US 12,249,401, issued 11 March 2025), “Methods and systems for analyzing nucleic acid molecules” (US 11,965,215, issued 23 April 2024), and “Identification and use of circulating nucleic acid tumor markers” (US 12,421,559, issued 23 September 2025), along with additional patents such as US 12,571,054 and US 12,562,239, and multiple pending applications on related technologies.[3][10][11]

Research and contributions

Alizadeh's early work with Patrick Brown and Louis Staudt led to the development of the Lymphochip cDNA microarray, which enabled genome-scale profiling of lymphoid malignancies.[12] Using this tool, Alizadeh and collaborators demonstrated that diffuse large B-cell lymphoma (DLBCL) comprises distinct molecular subtypes with different clinical outcomes, published in Nature in 2000.[13][14] This study reshaped lymphoma classification by incorporating gene expression profiling.[15][16]

At Stanford, Alizadeh's laboratory developed CIBERSORT and CIBERSORTx for immune cell deconvolution, and PhasED-Seq, EPIC-Seq, and CAPP-Seq for ultrasensitive detection of circulating tumor DNA.[17][18]

Alizadeh has authored or co-authored more than 140 peer-reviewed papers in journals such as Nature, Nature Medicine, Cell, Cancer Cell, Journal of Clinical Oncology, New England Journal of Medicine, JAMA, and others.[19][20]
