James Kirkland, MD, PhD
Dr. Kirkland’s research is on the contribution of fundamental aging processes, particularly cellular senescence, to age-related and chronic diseases and development of agents and strategies for targeting fundamental aging mechanisms to treat age- and chronic disease-related conditions and morbidities.
Additional research areas include molecular and physiological mechanisms of age-related adipose tissue and metabolic dysfunction, frailty, and loss of resilience to infections and acute diseases in old age.
Dr. Kirkland’s laboratory published the first article about agents that clear senescent cells – senolytic drugs. Dr. Kirkland demonstrated that senolytic agents enhance healthspan and delay, prevent, or alleviate multiple age-related disorders and diseases in mouse models. He published the first clinical trials of senolytic drugs and is currently conducting multiple clinical trials of senolytics, including three clinical trials for COVID-19. He has more than 225 publications and holds over 20 patents.

Steven Artandi, MD, PhD
Dr. Artandi is the Laurie Kraus Lacob Director of the Stanford Cancer Institute and the Jerome and Daisy Low Gilbert Professor of Medicine and Biochemistry at Stanford University. He also serves as the inaugural Senior Associate Dean for Cancer Programs for Stanford School of Medicine and the Chief Cancer Officer for Stanford Health Care.
Dr. Artandi is an oncologist and cancer biologist whose research work has focused on the role played by the enzyme telomerase in cancer, aging and stem cell function. His work has produced new insights into the origins of cancer, revealing how telomerase endows cells with immortal growth properties and how aspiring cancers circumvent critical bottlenecks encountered during carcinogenesis. He has received a number of awards including an Outstanding Investigator Award from the National Cancer Institute and is an elected member of the American Association for the Advancement of Science, the American Society for Clinical Investigation and the Association of American Physicians.

Michael M. Shen, PhD
The Shen lab investigates the molecular mechanisms of mammalian development and cancer using in vivo analyses of genetically-engineered mouse models.
The lab studies have expanded significantly to encompass analyses of prostate epithelial progenitor cells and their roles in organogenesis and tissue regeneration, focusing on the role of the Nkx3.1 transcriptional regulator as well as analysis of cell types of origin for prostate cancer. These studies have led to the identification of a luminal epithelial stem cell as well as support for a luminal cell of origin for prostate cancer, and most recently to the establishment of an organoid culture system for mouse and human prostate epithelium.
Most recently, the scope of Dr. Shen’s research has expanded to molecular studies of bladder cancer evolution and drug response through the analysis of patient-derived bladder tumor organoids.

Cyrus Ghajar, PhD
Dr. Cyrus Ghajar researches metastasis, or the spread of cancer cells to distant sites, and how the microenvironments of these sites (including bones) can put cancer cells to sleep – or wake them up. During the early days of tumor formation, disseminated tumor cells, or DTCs, often break away and travel through the bloodstream to distant areas of the body. If they stay asleep, or dormant, these DTCs remain harmless. But if (or when) they wake up – which may happen months, years or even decades after a patient receives early-stage treatment such as chemotherapy – they can create metastatic tumors that are resistant to treatment and eventually kill the patient.
Dr. Ghajar studies how the microenvironments within distant tissues regulate DTC dormancy and/or growth and whether these niches convey to dormant DTCs resistance to chemotherapy and immunotherapies. He believes that solving these puzzles will allow the development of drugs that eradicate dormant DTCs before they can develop into full-blown metastases. He conducts this work within the Hutch’s Laboratory for the Study of Metastatic Microenvironments.
