Much of her work has been devoted to the development of new analytical procedures for novel or emerging drugs of abuse, including psychostimulants and other designer amphetamines, including cathinones ("Bath Salts"). Other areas of interest include alcohol and drug-facilitated sexual assault, alternative and complex biological matrices and maternal-fetal medicine.

Current MS and PhD students in Dr. Kerrigan's laboratory are involved in a variety of projects including the systematic evaluation of cathinone stability, analysis of the opioid receptor agonist and psychoactive drug mitragynine ("Kratom") using high resolution mass spectrometry, desomorphine ("Krokodil") metabolism and analysis, gamma-hydroxybutyrate (GHB) in hair, and the new hypnotic drug suvorexant (Belsomra) in biological evidence.
