Adel Mutahar
Postdoctoral Scholar, General and Vascular Surgery
BioDr. Adel Z. I. Mutahar is a postdoctoral researcher in the Department of Surgery at Stanford University, working under the mentorship of Dr. Frederick M. Dirbas. His research focuses on translational breast cancer biology and emerging radiotherapy technologies, with an emphasis on tumor–microenvironment interactions, immuno-oncology, and preclinical therapeutic development. His academic journey spans three countries—beginning in Yemen, advancing through India, and now progressing at Stanford—reflecting his commitment to impactful cancer research and global scientific advancement.
Dr. Mutahar began his career in Yemen, earning his Bachelor’s degree in Medical Laboratory Sciences before joining Abs Community College as a faculty member. From 2007–2013, he held several academic leadership roles, including Academic Director, Head of Evaluation, and Assistant Dean of Students, where he modernized curriculum, expanded hands-on diagnostic training, and strengthened laboratory education infrastructure in resource-limited settings. His work contributed to building a more skilled medical diagnostics workforce and improving pathways for laboratory science education.
Awarded a prestigious national merit scholarship, Dr. Mutahar continued his graduate and doctoral training in India, completing his M.S. and Ph.D. in Biotechnology with a focus on triple-negative breast cancer. During his doctoral work, he developed 3D tumor spheroid models and combinatorial therapeutic strategies, demonstrating synergy between anti-angiogenic agents and chemotherapy in TNBC. He further advanced this research by creating an orthotopic murine model to investigate metastatic progression and demonstrated that knockdown of the MTA1 gene in mesenchymal stem cells (MSCs) significantly suppressed TNBC invasion, angiogenesis, and metastatic spread, introducing a promising stromal-targeted therapeutic concept for aggressive breast cancer. This work earned recognition through travel grants, conference presentations, and a Best Poster Award. His scientific adaptability was further demonstrated during the COVID-19 pandemic, when he uncovered a novel interaction between SARS-CoV-2 Spike RBD and VEGF signaling.
At Stanford, his work emphases on FLASH radiotherapy, an ultrahigh-dose-rate modality with the potential to widen the therapeutic window by minimizing normal-tissue toxicity while maintaining tumor control. Working within Dr. Dirbas’s translational breast oncology program, Dr. Mutahar employs patient-derived xenografts, orthotopic murine models, spatial transcriptomics, single-cell RNA sequencing, and immune profiling to dissect the biological mechanisms governing treatment response. His research integrates multi-omics analysis to map early and late radiotherapy injury pathways—including senescence, apoptosis and fibrosis. His goal is to develop mechanism-driven radio-immunotherapy strategies and durable FLASH-RT combination regimens that can be translated into clinical trials for breast cancer, improving therapeutic durability, minimizing toxicity, and ultimately enhancing patient outcomes.
Dr. Mutahar’s long-term vision is to establish an independent laboratory at the intersection of radiobiology, immuno-oncology, and translational therapeutics. Guided by Dr. Dirbas’s mentorship and shaped by multidisciplinary experience across three continents, he aims to develop biologically informed treatment strategies that eradicate tumors while preserving normal tissue and immune integrity—ultimately improving quality of life and survival for women with aggressive breast cancers. -

She graduated with a Bachelor of Science in Biochemistry and highest academic honor and distinction from U.C. Davis. She earned a Pharm.D degree from U.C.S.F. School of Pharmacy and a MD degree from U.C.S.D. She then did a residency in general surgery and a residency in Plastic and Reconstructive Surgery at the University of Southern California (USC) Medical Center. She further completed a fellowship in microsurgery from Chang Gung Memorial Hospital in Taiwan, one of the largest reconstructive surgery centers in the world. She was recruited to Stanford from Cedar Sinai Medical Center in 2012, and is currently a Clinical Professor in the Division of Plastic and Reconstructive Surgery at Stanford University.
Dr. Nguyen specializes in aesthetic and reconstructive breast surgery, surgical treatment of lymphedema including vascularized lymph node transfer and lymphaticovenous anastomosis, and complex tissue reconstruction utilizing microsurgery and supermicrosurgery. She also has interest in cosmetic surgery, including facial rejuvenation and body contouring procedures.
In addition to her clinical commitment, Dr. Nguyen has basic science and clinical research interests in lymphedema and breast reconstruction. She has published articles in peer review journals, presented at national and international professional meetings and has authored book chapters in various plastic surgery textbooks. She also enjoys volunteering on overseas medical missions and participating in medical charity activities. -
Kenneth Nieser
Postdoctoral Scholar, General Surgery
BioKen Nieser is a postdoctoral research fellow through the Big Data-Scientist Training Enhancement Program (BD-STEP) at the Palo Alto VA and in the Department of Surgery, Stanford School of Medicine. Ken received a BA in Physics and Mathematics from Swarthmore College and a PhD in Epidemiology with a minor in Statistics from the University of Wisconsin-Madison. During his PhD, Ken developed and applied statistical methods for improving algorithmic fairness of data analyses used to inform screening and treatment of mental illnesses. These projects included development of an approach for detecting sample subsets with differential psychological symptom patterns and a sample representation reweighting method for improving the precision of subgroup-specific treatment effect estimation.
Ken’s current research interests are in health care inequities, quality measurement, and algorithmic fairness. During his fellowship, Ken will be working on investigating the statistical reliability of quality measures and decomposing health care disparities to provide practical information for resolving inequities, with applications in mental health care and surgical care. -
