burt ovrut

burt ovrut is an american theoretical physicist most famous for his work on heterotic string theory .
he is currently professor of theoretical high energy physics at the university of pennsylvania .
ovrut earned his ph.d. in physics at the university of chicago in 1978 .
his doctoral advisors were benjamin w. lee and yoichiro nambu , and his thesis was on an sp -lrb- 4 -rrb- x u -lrb- 1 -rrb- theory of the weak and electromagnetic interactions .
ovrut is one of those who pioneered the use of m-theory to explain the big bang without the presence of a singularity .
recently burt ovrut and his collaborators constructed a calabi-yau compactification that reproduces the minimal supersymmetric standard model without any exotics .
