Department of Physics
University of Prince Edward Island
Canada
Biography
He did his Phd from Dalhousie and is a the Acting chair person & Assistant professor of Physics Department in UPEI, Canda.
Research Interest
Dr. Derek Lawther, an experimental physicist, uses positron annihilation to identify defects in materials such as metals. He probes for defects at the atomic level and works to understand better how to manipulate these defects to produce enhanced physical properties such as increased strength or conductivity.
