Forskning
Min forskning fokuserar på detektionstekniker och datainsamlingssystem för experiment inom högenergifysik, med målet att söka efter fysik bortom standardmodellen.
För närvarande är jag ansvarig för tillverkningen av de nya ATLAS Inner Tracker (ITk) endcap-hybriderna för Sverige, som produceras inom industrin. Jag är huvudkoordinator och ansvarar för integrationen av våra tillverkningstekniker i en mer gemensam mikrohalvledarproduktionskedja.
Historiskt sett har jag varit involverad i simulering av gasdetektorer, närmare bestämt GEMs för CMS, arbetat med uppgraderingar av ATLAS pixeldetektor och utfört sökningar efter ny fysik, specifikt sökningar efter supersymmetri med stopp-parproduktion som antingen sönderfaller till Z- eller Higgsbosoner. Jag har också arbetat med LDMX, både inom beräkningar och på utformningen av LDMX hadronkalorimeter."
