Making Sense of Biological Designs

We are curious about how biological systems are built. We want to understand the engineering principles and molecular mechanisms of how things are built and how things function. In the lab, we study multiple scales of biological organisation, from small protein circuits, signaling pathways, developmental programs, to organisms. We enjoy using various tools, such as paper-and-pencil mathematical modeling, computer simulation, biochemistry, single-cell imaging, histology, molecular biology, experiments in frog embryos, and lately, some cutting and grinding experiments in jellies.

And it’s summer time again.  We welcome Laura Ratliff, a rising senior from Flintridge Prep, returning to the lab this time to learn to clone and make movies of cells.  We also welcome a new technician in the lab, Andrew Liu, who graduated from Cal and joined the lab to tackle the b-catenin project with Kibeom.  We have great hopes for him.

We got interviewed again!  This time by the NPR Big Picture Science.  Click here to listen to Lea and Michael explaining symmetrization to Molly Bentley and Seth Shostak, a Caltech alumnus himself.

We are sad Clare is leaving.  She has been such a great presence in the lab.  But we are  happy that she’s going to an exciting Master program in Regenerative Stem Cells at USC.  Here is a toast to the bright future ahead!
