Gheorghe Chistol
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.

Bill Chiu
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.

Wah Chiu
Wallenberg-Bienenstock Professor and Professor of Bioengineering and of Microbiology and Immunology
Current Research and Scholarly InterestsMy research includes methodology improvements in single particle cryo-EM for atomic resolution structure determination of molecules and molecular machines, as well as in cryo-ET of cells and organelles towards subnanometer resolutions. We collaborate with many researchers around the country and outside the USA on understanding biological processes such as protein folding, virus assembly and disassembly, pathogen-host interactions, signal transduction, and transport across cytosol and membranes.

Valerie Chock
Professor of Pediatrics (Neonatology) and, by courtesy, of Obstetrics and Gynecology (Maternal Fetal Medicine)
Current Research and Scholarly InterestsNeurological monitoring in critically ill infants. Altered hemodynamics in neonates, especially in relation to prematurity, congenital heart disease, and central nervous system injury. Determination of the hemodynamic significance and effects of a patent ductus arteriosus in the preterm infant. Utilizing NIRS (near-infrared spectroscopy) and other technologies for improved monitoring in the NICU.

Eun Young Choi, PhD
Instructor, Neurosurgery
Current Research and Scholarly InterestsDr. Choi is broadly interested in mapping the brain’s connectivity and characterizing its functional dynamics using advanced neuroimaging and clinical neurophysiological methods, as well as utilizing this information to identify individual-specific neurosurgical targets for neuromodulation (e.g., deep brain stimulation). Her prior work has mapped the functional and connectional organization of the striatum using neuroimaging and neuroanatomical connectivity methods. She is currently focused on the use of thalamic deep brain stimulation to improve memory and attention in traumatic brain injury and Alzheimer’s disease.

Danny Hung-Chieh Chou
Assistant Professor of Pediatrics (Endocrinology) and, by courtesy, of Chemical and Systems Biology
Current Research and Scholarly InterestsOur research program integrates concepts of chemical biology, protein engineering and structure biology to design new therapeutic leads and generate probes to study biological processes. A key focus of our lab is insulin, an essential hormone in our body to reduce blood glucose levels. We generate synthetic libraries of insulin analogs to select for chemical probes, and investigate natural insulin molecules (e.g. from the venom of fish-hunting cone snails!) to develop novel therapeutic candidates. We are especially interested in using chemical and enzymatic synthesis to create novel chemical entities with enhanced properties, and leverage the strong expertise of our collaborators to apply our skill sets in the fields of cancer biology, immunology and pain research. Our ultimate goal is to translate our discovery into therapeutic interventions in human diseases.

Angele Christin
Associate Professor of Communication and, by courtesy, of Sociology
Current Research and Scholarly InterestsAngèle Christin studies how algorithms and analytics transform professional values, expertise, and work practices.
Her book, Metrics at Work: Journalism and the Contested Meaning of Algorithms (Princeton University Press, 2020) focuses on the case of web journalism, analyzing the growing importance of audience data in web newsrooms in the U.S. and France. Drawing on ethnographic methods, Angèle shows how American and French journalists make sense of traffic numbers in different ways, which in turn has distinct effects on the production of news in the two countries. She discussed it on the New Books Network podcast.
In a related study, she analyzed the construction, institutionalization, and reception of predictive algorithms in the U.S. criminal justice system, building on her previous work on the determinants of criminal sentencing in French courts.
Her new project examines the paradoxes of algorithmic labor through a study of influencers and influencer marketing on YouTube, Instagram, and TikTok.
