Lucas B. Sullivan

Lucas B. Sullivan, PhD is an Associate Professor in the Human Biology Division at Fred Hutchinson Cancer Center and an Affiliate Associate Professor in the Basic Sciences Division at Fred Hutch. He also holds an appointment as Affiliate Assistant Professor in the Department of Biochemistry at the University of Washington. Dr. Sullivan leads the Sullivan Lab, which focuses on understanding the metabolic constraints of cell proliferation with the goal of improving cancer treatment.

Dr. Sullivan's educational background includes:

• Postdoctoral Fellowship, Massachusetts Institute of Technology, Koch Institute for Integrative Cancer Research (2018)
• PhD, Feinberg School of Medicine, Northwestern University (2013)
• BS in Biochemistry, California Polytechnic State University (2007)

Dr. Sullivan's research centers on cell metabolism under normal and cancerous conditions. His lab investigates how tumors modify their metabolic pathways to support increased demand for cellular components and building blocks that enable excess cell growth. He studies aspartate metabolism, coenzyme homeostasis, and the discovery of novel metabolic products and pathways. His work aims to outline the metabolic pathways tumors rely on to grow and progress, identifying potential targets for future cancer therapies. Dr. Sullivan challenges established metabolic dogma, questioning textbook assumptions about mitochondrial function and metabolic pathways in cancer cells. His research has shown that mitochondria function not just as powerhouses but also as factories producing molecular building blocks essential for cancer cell proliferation.

Analysis of Dr. Sullivan's recent publications (2023-2025) reveals a strong focus on metabolic dependencies in cancer, particularly around aspartate metabolism, lipid scavenging, and mitochondrial adaptations. His work spans from basic science discovery to translational applications, with several studies identifying potential therapeutic targets. A recurring theme is how cancer cells rewire their metabolism to support proliferation, with particular attention to how metabolic alterations create vulnerabilities that could be exploited for therapy. His research increasingly incorporates multi-omics approaches and in vivo models to understand metabolic networks in the tumor microenvironment.
