Dr. Liao is very focused on her patients and the overall improvement of outcomes in critical care treatments. As part of this focus, she is interested in looking at genetic predispositions to critical illnesses. In support of her clinical and research interests, Dr. Liao is involved in several trials. Currently, Dr. Liao is principal investigator involved in a multicenter study investigating behavior and developmental outcomes in children who have had pertussis through the Collaborative Pediatric Critical Care Research Network and the Eunice Kennedy Shriver National Institute of Child Health and Human Development. Along with the rest of the critical care division, Dr. Liao is working as an investigator on three additional studies. The first is in conjunction with the Centers for Disease Control, in which Dr. Liao is investigating genetic epidemiology of life-threatening influenza infection in children. Another study is a multicenter, randomized, masked placebo-controlled trial to assess the safety and efficacy of lucinactant in acute hypoxemic respiratory failure in children up to two years of age. She is also involved in an investigator-initiated trial started at Cincinnati Children’s Hospital Medical Center in which she is studying genomic analysis of pediatric systemic inflammatory response syndrome.

Dr. Liao’s commitment to critical care research and international health are evident through her publications, abstracts, and invited lectures.
