Diane Barber, PhD

Professor

Cell and Tissue Biology

The Barber Lab addresses questions on the fundamental cell biology of epithelial plasticity to understand dysregulated functions in human diseases. Our primary focus on how pHi dynamics regulates cancer cell behaviors such as migration and metabolic reprogramming and stem cell behaviors and lineage specification bridges protein electrostatics with cell biology, revealing protonation as a post-translational modification regulating protein conformations and functions.

Jeffrey Bush, PhD

Professor and Chair

Cell and Tissue Biology

The Bush lab studies basic mechanisms by which signaling between cells coordinates mammalian morphogenesis. Understanding this control has significance beyond its fundamental importance in development since birth defects are the leading cause of death for infants during the first year of life. We utilize multiple approaches based in mouse genetics to understand fundamental signaling processes as they relate to development and disease with particular foci in the craniofacial and respiratory systems.

Fred Chang, PhD, MD

Professor

Cell and Tissue Biology

The Chang Lab studies cell morphogenesis and cell division. We are interested in fundamental questions concerning spatial organization within a single cell: How do cellular components organize to form cells of a specific size and shape? How might cells sense their own shape and size? Topics include: cytokinesis, placement of the cell division plane, cell polarity, dynamics of microtubules and actin, biomechanics of cell morphogenesis, and sensing of cell shape and size.

Semil Choksi, PhD

Assistant Professor

Cell and Tissue Biology

The Choksi Lab studies how airway stem cells differentiate to build and maintain the respiratory epithelium. We focus on multiciliated cells - specialized epithelial cells that protect the lung by clearing inhaled pathogens. By combining mouse genetics, single-cell technologies, and imaging-based approaches, we aim to uncover novel principles underlying multiciliated cell differentiation. Our long-term goal is to identify new therapeutic strategies for restoring cellular function in respiratory disease.

Andrei Goga, MD, PhD

Professor

Cell and Tissue Biology

The Goga Lab seeks to understand how specific oncogenes alter the cell cycle, miRNA and metabolic signaling pathways to drive tumorigenesis. We study how cancer signaling pathways are activated in breast and liver cancers and hematopoietic malignancies, amongst the most prevalent and deadly forms of human cancer. We are particularly focused on the MYC oncogene, the downstream pathways it activates, and synthetic-lethal strategies to target MYC overexpressing cancers.

Carol Gross, PhD

Professor

Cell and Tissue Biology

The Carol Gross Lab takes genetic, biochemical, and systems approaches to study regulatory mechanisms of E. coli stress responses, protein interactions in the bacterial transcription apparatus, and genome-wide control of gene expression.

Erica Hutchins, PhD

Assistant Professor

Cell and Tissue Biology

The Hutchins Lab seeks to map how post-transcriptional regulation controls developmental pluripotency and cell fate decisions in vivo, using vertebrate neural crest as a model. Neural crest cells are an essential stem cell population in the vertebrate embryo. Dysregulated post-transcriptional regulatory linkages in neural crest can lead to congenital malformations and cancer in humans, and a thorough understanding of the mechanisms underlying these fundamental processes can provide new therapeutic targets for biomedical intervention.

Elizabeth Joyce, PhD

Professor

Microbiology and Immunology

Dr. Joyce is a teaching faculty with a joint appointment in the School of Medicine.  She co-directs first and second year Dental school courses in anatomy and physiology (BMS 116, 118, and 126) with Dr. Barbie Klein and directs BMS 117, which is focused on infectious disease and immunology. Dr. Joyce is passionate about health professions education and is a member of the Academy of Medical Educators. 

Barbie Klein, PhD

Associate Professor

Anatomy

Dr. Barbie Klein, MS, PhD, is an Assistant Professor with joint appointments in the School of Dentistry and the School of Medicine. Dr. Klein teaches gross anatomy, human embryology, histology, and neuroanatomy to health professional students and continuing education healthcare learners. She is the anatomy and embryology Discipline Director for second-year medical student courses and Co-Director with Dr. Joyce of the Biomedical Sciences curriculum for dental students.

Sarah Knox, PhD

Professor

Cell and Tissue Biology

The Knox Lab is concerned with analyzing the cellular and molecular events underlying the formation of epithelial organs (organogenesis) and their regeneration after injury. We employ multiple tissues (e.g. salivary gland, pancreas, ocular organs) to test three fundamental biological questions: 1) how do peripheral nerves impact epithelial stem cell fate decisions; 2) what are the mechanisms by which neuronal signals pattern organ architecture; and 3) how do immune cells modulate nerve-mediated morphogenesis, repair and regeneration.

Matthew Kutys, PhD

Assistant Professor

Cell and Tissue Biology

The Kutys Lab spans disciplinary boundaries between cell biology and engineering to answer fundamental questions in tissue morphogenesis and mechanobiology. We develop and apply biomimetic human tissue models, along with cellular and molecular technologies, to identify mechanisms across biological scales that govern cell-tissue structure and function. We aim to use these discoveries to inform the selection of candidate therapies and the design of next gen preclinical models for human cancer and cardiovascular disease.

Noelle L'etoile, PhD

Professor

Cell and Tissue Biology

The L'Etoile Lab investigates how neurons perceive and transmit information both in response to novel and persistent environmental cues. We use the nematode C. elegans because its neuronal circuitry is completely described, and exhibits robust plasticity. C. elegans also allows us to use powerful cell biological, genetic, behavioral, physiological and molecular techniques to study plasticity.
