Research Description

Sanjay Kumar is the Chancellor's Professor and Director, California Institute for Quantitative Biosciences at UC Berkeley (QB3-Berkeley).  The Kumar Lab research team seeks to understand and control biophysical communication between cells and their surroundings.  A large portion of their work involves the integration of biomaterials science, single-cell technologies, and advanced imaging to dissect molecular mechanisms through which cells sense, process, generate, and respond to mechanical forces. In addition to investigating fundamental aspects of this problem, they are especially interested in applying their insights to control tumor and stem cell biology, particularly in the central nervous system.  For example, they have developed materials to control neurogenesis and deliver stem cells to tissue, and they have created new technological platforms to model the invasion of brain tumors, which may in turn be used to discover new therapies. 

QB3 was established in 2000 as a Governor Gray Davis Institute for Science and Innovation and consists of a central administration together with institutes on the campuses of UC Berkeley, UCSF, and UC Santa Cruz.  QB3's goals are to fuel the California bioeconomy, support research and training in quantitative biosciences, and translate academic research into products and services that benefit society.  QB3-Berkeley organizes and administers core research facilities, incubator space (QB3 Garage@Berkeley), and educational and career development programs.  QB3-Berkeley also oversees and is based in Stanley Hall, a 285,000 sq. ft. multidisciplinary research and teaching building on the Berkeley campus.

Five Berkeley top scholars named AAAS fellows

Five Berkeley scholars — four faculty members and one research scientist — have been elected fellows of the American Association for the Advancement of Science (AAAS), one of the world’s largest scientific societies. The distinction was awarded this year to 489 scientists, engineers and innovators for their advancement of science and its applications.

Making chicken feathers

The rubber-like elasticity of skin, which contracts to its original shape after being stretched, is key to the development of regularly spaced hairs and sweat glands during development, according to new research at the University of California, Berkeley.

Tracking Cancer’s Advance in 3D

Sanjay Kumar adapts bioengineering strategies for studies in 3D cell environments to reveal how and why cancer cells invade the way they do.

Scientists create new protein-based material with some nerve

UC Berkeley scientists have taken proteins from nerve cells and used them to create a “smart” material that is extremely sensitive to its environment. This marriage of materials science and biology could give birth to a flexible, sensitive coating that is easy and cheap to manufacture in large quantities.

Kumar and Murthy receive Keck Fund award

Bioengineering professors Sanjay Kumar and Niren Murthy have been granted a $500,000 research award from the W.M. Keck Foundation for their project, Single Tumor Cell Proteomics for Diagnosis and Prognosis.

Tumor cells move faster through tight spaces

Tight spaces have the counterintuitive effect of aiding the spread of tumor cells, according to a new study led by UC Berkeley bioengineers. The researchers developed a 3D model to study the biophysical environment factors influencing tumor invasion and found that narrow channels gave cells traction to help them move faster. The findings have implications for certain cancers, including malignant brain tumors, which tend to infiltrate most rapidly along tissue interfaces and confined spaces, such as blood vessels and nerve tracts.
