Dr. LaCourse’s research focuses on improved tuberculosis prevention, screening, and detection with a focus on people with HIV, including pregnant people and children. She leads clinical cohorts of pregnant people and children evaluating diagnostics for latent and active TB infection as well as interventional studies evaluating TB prevention therapy including among HIV-exposed uninfected children and pregnant people with HIV. Active areas of research include evaluation of non-sputum based TB diagnostics as well as the role of pregnancy and HIV in TB susceptibility. An additional area of scientific focus is SAR-CoV-2 antibody responses in pregnant people and their infants.

Dr. LaCourse is a GWACh (Global Women, Adolescent, and Child health) scientific lead, Kenya Research and Training Center (KRTC) faculty member, Tuberculosis Research & Training Center (TRTC) leadership committee member, and TB ECHO (Extension for Community Healthcare Outcomes) faculty, and co-leads the Development core of the recently awarded NIH Seattle TB Research Advancement Center (SEA-TRAC). She is committed to the inclusion of children and pregnant women in HIV/TB research as an IMPAACT (International Maternal Pediatric Adolescent AIDS Clinical Trials Network) TB Scientific Committee mentored junior investigator, and International Union Against TB and Lung Disease Maternal Child Health Working Group Scientific Co-Lead.

She is an attending physician at the Madison HIV clinic and infectious diseases, general medicine, and HIV inpatient services at the University of Washington and Harborview Medical Centers.
