Current Research and Scholarly InterestsActive Wnt signaling maintains somatic stem cells in many organ systems. Using Wnt target genes as markers, we have characterized distinct cell populations with stem cell behavior in the inner ear, an organ thought to be terminally differentiated. Ongoing work focuses on delineating the developing significance of these putative stem/progenitor cells and their behavior after damage.
Member, Stanford Cancer Institute
Current Research and Scholarly InterestsThe use of molecular and molecular cytogenetic methods to identify chromosomal abnormalities in acquired and congenital disorders.
Professor of Medicine (Gastroenterology and Hepatology)
Current Research and Scholarly InterestsDr. Cheung's research interests focus on liver diseases, with emphasis on viral hepatitis. His past research include investigating the mechanism of viral neutralization of hepatitis B virus at the molecular level and immune response to hepatitis C virus. Dr. Cheung is studing various aspects of hepatitis C, both clinical and translational research.
Professor of Microbiology & Immunology
Current Research and Scholarly InterestsContribution of T cells to immunocompetence and autoimmunity; how the immune system clears infection, avoids autoimmunity and how infection impacts on the development of immune responses.
Albert Sean Chiou, MD, MBA
Clinical Associate Professor, Dermatology
Current Research and Scholarly InterestsI am a clinical researcher interested in evaluating promising new diagnostic paradigms and treatments for serious or poorly treated, chronic skin conditions. My research currently includes:
- Treatments for itch from epidermolysis bullosa
- Treatments for chronic wounds for patients with recessive dystrophic epidermolysis bullosa (In collaboration with Dr. Jean Tang and Dr. Peter Marinkovich)
- Treatments for atopic dermatitis, psoriasis, and other inflammatory skin conditions
- Artificial intelligence approaches for melanoma and skin cancer early detection
- Imaging mass spectrometry for skin cancer margin analysis and diagnosis
I collaborate with other faculty within the Stanford Skin Innovation and Interventional Research Group (SIIRG) to conduct investigator initiated and sponsored clinical trials seeking to improve care for important dermatologic diseases

Assistant Professor of Chemical and Systems Biology
Current Research and Scholarly InterestsResearch in my laboratory is aimed at understanding how eukaryotes replicate their DNA despite numerous challenges (collectively known as replication stress), and more generally – how eukaryotic cells safeguard genome integrity. Specifically, we are investigating: (i) mechanisms that regulate the activity of the replicative helicase during replication stress, (ii) mechanisms that control the inheritance of epigenetic information during replication, and (iii) mechanisms of ubiquitin-mediated regulation of genome maintenance. We utilize single-molecule microscopy to directly image fluorescently-labeled replication factors and track them in real time in Xenopus egg extracts. I developed this system as a postdoctoral fellow, and used it to monitor how the eukaryotic replicative helicase copes with DNA damage. We plan to further extend the capabilities of this platform to directly visualize other essential replication factors, nucleosomes, and regulatory post-translational modifications like ubiquitin chains. By elucidating molecular mechanisms responsible for maintaining genome stability, we aim to better understand the link between genome instability and cancer, and how these mechanisms can be harnessed to improve disease treatment.
Associate Professor of Surgery (Pediatric Surgery)
BioDr. Chiu obtained his B.S. degree in Biological Sciences and graduated with Honors from Stanford University. After graduating, he received his Medical Degree at Northwestern University Feinberg School of Medicine, where he remained for his internship and General Surgery residency training. Dr. Chiu completed his Pediatric Surgery training at The Children’s Hospital of Philadelphia. He is an Associate Professor at Stanford University School of Medicine where he has an active research program studying innovative approaches to treat patients with neuroblastoma.
Current Research and Scholarly InterestsMy major research interests include cancer epidemiology with a concentration in early detection and screening for cancer. My current research focuses on second malignancies among cancer survivors with special interests in causal inference from real-world observational data sources, dynamic risk predictive modeling, and simulation models of cancer control interventions on their effects on population trends in incidence and mortality. My research involves the application of competing-risk and high-dimensional data analysis using large population-based prospective cohorts, clinical trial data, electronic health records extracted through the data mining process, and cancer genomics data.
Professor of Medicine (Oncology) and of Biochemistry
Current Research and Scholarly InterestsAfter shuttering the wet lab, we have focused on: a point-of-care device to measure blood ammonia and prevent brain damage; a human protein complex that juxtaposes and joins DNA ends for repair and V(D)J recombination; and strategies for teaching students and for reducing selection bias in educational programs.

Current Research and Scholarly InterestsOur lab is interested in understanding molecular processes that underlie aging and age-associated pathologies in mammals. We focus on a family of genes, the SIRTs, which regulate stress resistance and lifespan in lower organisms such as yeast, worms, and flies. In mammals, we recently uncovered a number of ways in which SIRT factors may contribute to cellular and organismal aging by regulating resistance to various forms of stress. We have now begun to characterize the molecular mechanisms by which these SIRT factors function. In particular, we are interested in how SIRT factors regulate chromatin, the molecular structure in which the DNA of mammalian genomes is packaged, and how such functions may link genome maintenance to stress resistance and aging.
