Meru J. Sadhu, Ph.D.
Meru Sadhu is an Earl Stadtman Investigator and head of the Systems Biology and Genome Engineering section at the National Human Genome Research Institute. He obtained his Bachelor's degree from Caltech, and then did his doctoral studies at UC Berkeley with Jasper Rine. For his postdoc, Dr. Sadhu joined Leonid Kruglyak's lab at UCLA, to complement his background in classical genetics with training in quantitative genetics. He developed approaches to apply CRISPR technology to quantitative genetics questions, including using CRISPR to direct recombination, and also to examine in parallel the effects of thousands of specific genetic variants. In the Systems Biology and Genome Engineering Section, he plans to use these and other new methods to address important questions in genetics.
The Systems Biology and Genome Engineering Section's goal is to systematically understand the effects of genetic differences. Researchers in this section study genetic diversity across an expansive range, such as natural variation between individuals or between species, or novel genetic changes that they create. By studying the functional effects of these variants, section researchers work to learn principles of genome function.
Section researchers use genome engineering to direct activities such as genome editing or recombination, using budding yeast as a model organism. As the space of potential genetic variants is immense, the section's researchers study large numbers of genetic differences in parallel. They do this by using large-scale oligonucleotide synthesis to generate a diversity of instructions targeting desired modifications, in order to generate pools of cells containing thousands of unique genomic changes. In addition to existing genome engineering methods, the section is continually developing new approaches to further expand the genetic space that can be studied.
