The ability to perturb genes in human cells is crucial for elucidating gene function and holds
great potential for finding therapeutic targets for diseases such as cancer. To extend the …

Using ultrafast optical pump-probe spectroscopy, we have measured carrier relaxation
times in epitaxial graphene layers grown on SiC wafers. We find two distinct time scales …

The ultrafast relaxation and recombination dynamics of photogenerated electrons and holes
in epitaxial graphene are studied using optical-pump terahertz-probe spectroscopy. The …

We present experimental results on the optical absorption spectra of epitaxial graphene
from the visible to the terahertz frequency range. In the terahertz range, the absorption is …

… KL holds a Canada Vanier Graduate Scholarship, MA holds a postdoctoral fellowship
award from the Swiss National Science Foundation, and M. Chandrashekhar. holds an Ontario …

The observation that BRCA1- and BRCA2-deficient cells are sensitive to inhibitors of poly(ADP–ribose)
polymerase (PARP) has spurred the development of cancer therapies that use …

… M Γ and M K are the number of phonon modes (per unit area) at the Γ and K ( K ′ ) points,
… The value of M Γ then corresponds to the number of phonon modes that are in the annular …

Electron-hole generation and recombination rates for intravalley and intervalley phonon
scattering in graphene are presented. The transverse and the longitudinal optical phonon …

We report on a method to produce free-standing graphene sheets from epitaxial graphene
on silicon carbide (SiC) substrate. Doubly clamped nanomechanical resonators with lengths …

Forward genetic screens with CRISPR–Cas9 genome editing enable high-resolution
detection of genetic vulnerabilities in cancer cells. We conducted genome-wide CRISPR–Cas9 …
