Chad L Barber, Ph.D.
Assistant Professor of Biology
Dr. Barber is a cell and molecular biologist. Research in his laboratory with undergraduate students focuses on aspects of cell-cell and cell-matrix interactions. Mentored project areas include:
- Roles of Immune cells in tumor microenvironment.
- Expression of integrin receptors on immune cells in the tumor microenvironment.
- Effects of integrin inhibition on tumor immune cell adhesion, proliferation and survival.
Dr. Barber's lab works with human and mouse cell lines in vitro as model systems, in addition to canine tissue. With the help of local veterinary clinics we aquire biopsies of canine tumors and study them in the lab. Our projects focus on the cell surface receptor molecules called integrins. These receptors allow attachement of cells to each other and also to their surroundings. We study the effects of blocking the adherence of these receptors in various cell types and assaying the behavior of the cells. Integrins are an attractive target for therapy in human cancers and may be in canine cancers as well.
Before beginning his graduate work, Dr. Barber received a Masters from Cal. State Univ., Northridge (Master's candidate) in Biology, with a thesis focusing on reproductive biology, specifically sperm-egg interactions. He then began a research stint at UCLA in the department of Radiation Biology for 2 years in the lab of Dr. William McBride and Dr. Keisuke Iwamoto. Dr. Barber contributed to several publications with his work there and subsequently started a Ph.D. program at UCLA.
During his graduate work in the lab of Luisa Iruela-Arispe, Dr. Barber's research was in two main areas: vascular biology (the study of blood vessels and their formation) and developmental hematopoiesis (the generation of blood cells). After completing his Ph.D. in Molecular Biology, he taught as a Lecturer at UCLA in several different courses including Developmental Biology and an honors course in Human Aging. In 2008, he started a Post Doctoral Fellowship in the lab of Ken Dorshkind at UCLA. There he studyied lymphocyte progenitors and the molecular mechanisms in B cell differentiation.
Currently, Dr. Barber teaches several Introductory Biology lecture and lab courses, as well as upper division Cell Biology, Developmental Biology, Cancer Biologya and Immunology.
Dr. Barber also developed and organizes the annual Cell Biology Symposium. The half-day symposium includes research, public awareness and ethics seminars by leading experts and is held in early spring. The 2014 topic was "In the Crosshairs: Targeting Cancer" and included 3 experts in cancer cell biology and novel research into treatments.

Stem cell biology, immunology, hematopoiesis (the process of generating blood cells from bone marrow stem cells), vascular biology, reproductive and developmental biology. His research interests at C.L.U. include cell-cell and cell-matrix interactions and how they affect cell growth and differentiation.
