Mohammad Shahrokh Esfahani
Assistant Professor of Radiation Oncology (Radiation and Cancer Biology)
BioI lead a computational oncology laboratory that develops machine learning and statistical methods for high-dimensional genomics, with particular expertise in Bayesian and uncertainty-aware modeling to integrate prior biological knowledge with large-scale datasets.
Our research centers on liquid biopsy analytics—especially cell-free DNA (cfDNA)—to noninvasively quantify genetic and epigenetic states relevant to cancer detection, monitoring, and tumor evolution. We developed EPIC-seq, a fragmentomics-based method that uses cfDNA fragmentation patterns to infer regulatory activity and gene expression programs, providing a scalable framework for epigenetic profiling from blood.
A core methodological focus of the lab is enabling reliable inference in extremely low signal-to-noise settings that are typical of cfDNA and early-stage disease. We build robust, interpretable models and benchmarking frameworks that support clinical translation, with the long-term aim of democratizing access to sensitive, minimally invasive cancer diagnostics. -

Nicholas Trakul, MD, PhD
Clinical Professor, Radiation Oncology - Radiation Therapy
BioDr. Nicholas Trakul is a radiation oncologist with Stanford Medicine Cancer Center and clinical associate professor of Radiation Oncology-Radiation Therapy with Stanford School of Medicine. Dr. Trakul serves as Medical Director for Stanford Medicine Radiation Oncology in Pleasanton and for the Stanford Medicine I Sutter Health Cancer Collaborative in Castro Valley.
Dr. Trakul completed residency training at Stanford in 2013 and then joined the faculty at the University of Southern California, where he specialized in head and neck and central nervous system malignancies, with an emphasis on stereotactic radiosurgery (SRS) and stereotactic ablative radiotherapy (SABR/SBRT). He is widely published as first author in peer-reviewed journals. His research focus involves the creation of novel clinical databases as well as outcomes in the treatment of head and neck, gastrointestinal and thoracic malignancies. In 2017, Dr. Trakul returned to Stanford Medicine, becoming the Medical Director of Stanford Medicine Radiation Oncology in Pleasanton. In 2020, he was named Medical Director of Stanford Radiation Oncology Network Sites. Dr. Trakul served as medical directorship of Eden Radiation Oncology Center from 2022 to 2023, the first site to become operation under the Stanford/Sutter Cancer Collaborative. In 2024, he was named Vice Chair and Director of the Radiation Oncology Network. In November of 2024, Dr. Trakul was named Medical Director of Alta Bates Herrick Radiation Oncology. He is focused on providing access to high quality radiation therapy, collaboration with community health care systems and creating/maintaining productive and high engagement workplace culture. He believes in providing personalized, high-quality care, and bringing new technology to the East Bay, allowing patients to access cancer care while staying connected to their communities and support networks. -
