         Lijuan Ruan, tenured physicist at physics department of Brookhaven National

Laboratory (BNL). She obtained PhD in high energy nuclear physics from

University of Science and Technology (USTC) in 2005 and Bachelor of Science

from USTC in 2000. She did postdoctoral research at Lawrence Berkeley

National Laboratory during 2005-2007. Then she worked as Goldhaber Fellow,

Associate Physicist, Physicist from 2007 to 2015 at BNL. She became Tenured

Physicist of BNL in 2015. She has been working on STAR experiment at RHIC

since 2000, and her research focus over the past years has been on the

experimental study of relativistic heavy ion collisions, with a goal of

understanding the bulk properties of strongly-interacting matter under extreme

conditions.

Abstract:

      The Electro-Magnetic probes have been widely used to study the fundamental

properties of hot, dense medium created in heavy ion collisions. Quarkonia

through dileptonic decays have been an indicator of the de-confinement while

the dileptons radiated from the hot, dense medium have been used to study

Chiral Symmetry Restoration, the temperature, and lifetime of the medium.

I will review a few interesting observables in heavy ion collisions enabled by

the STAR Time of Flight and Muon Telescope Detector upgrades. In addition, I

will present most-recent STAR results on J/psi and dilepton production in the

very low transverse momentum region (pT<0.2 GeV/c) in peripheral and midperipheral

Au+Au collisions. Physics implications and future perspectives will be

discussed.
