Dr. Marija Marjanovic joined OU as a research scientist in December 2022. She leads the OU effort on the ATLAS inner tracker pixel detector for use at the High Luminosity LHC. She also works on OU data analysis projects using data collected by the ATLAS detector, most recently a search for vector-like leptons to be submitted for publication in the near future. She is also contributing to the cross-section measurement of the electroweak production of the top quark, which will also be used to set confidence level limit on non-standard model phenomena.
