Post-Doctoral Researchers

  • Dr. Susan Dittmer
    SES 2259

    Dr. Susan Dittmer is a postdoctoral research assistant working with the experimental high energy group at UIC. ¬†She received her PhD in Physics from Cornell University in 2017. As a member of the CMS experiment at the CERN LHC, Susan works to precisely measure properties of the Higgs boson — in particular its coupling to W bosons. She also tests readout electronics and silicon semiconductor sensors for a future upgrade of the CMS silicon pixel tracker.

  • Dr. Titas Roy
    SES 2259

    Dr. Titas Roy is a postdoctoral research associate in the experimental high energy group at UIC. She received her doctorate degree from Florida Institute of Technology, working on precision measurements of top quark pair events in association with a photon, in 2018. She also worked extensively on the electronics upgrade of the hadronic calorimeter in the CMS detector. Dr. Roy is currently searching for a heavy Z prime boson which decays into a top quark pair along with studying and testing electronic readout modules of the silicon pixel tracker for the upgrade of the CMS detector.

  • Dr. Zhenbin Wu
    SES 2126

    Dr. Zhenbin Wu is searching for the supersymmetric partner of the top quark, top squark, in all-hadronic final state using top tagging technique at CMS. He have been involved with coordination and development of the trigger menu for the Phase 1 Level-1 trigger system of CMS. Dr. Wu is working on the Correlator system of Phase 2 Level-1 trigger, focusing on the jet clustering and substructure algorithm. He is also developing a package called “hls4ml”, for fast inference of deep neural networks in FPGAs.

  • Dr. Marguerite B. Tonjes
    Research Specialist

    Dr. Marguerite B. Tonjes is a Research Specialist at the University of Illinois – Chicago. She is based at Fermilab and provides computing support to members of the CMS (Compact Muon Solenoid) experiment. Marguerite’s work involves computing education of high energy physicists, solving problems, and working with Fermilab computing to advance the computing resources for the U.S. members of the CMS collaboration. Marguerite received her PhD in Nuclear Physics from Michigan State University in 2002 working on studies of the fundamentals of high energy nuclear particle collisions. She was a research associate and research scientist at University of Maryland, working on the CMS experiment to study relativistic nuclear collisions. She has contributed to over 1,000 scientific publications
