W 1993 roku rozpoczęłam studia wyższe na Wydziale Chemii UMCS w Lublinie, na kierunku Chemia z Fizyką. Studia te ukończyłam w czerwcu 1998 roku składając egzamin magisterski.  Od 1.10.1998 r. zostałam zatrudniona w Zakładzie Chemii Analitycznej i Analizy Instrumentalnej na stanowisku asystenta, a w 2006 roku po obronie pracy doktorskiej (2005 r.) na etacie adiunkta.
