Relevant to the pursuit of personalized medicine in psychiatry, Dr. Webb’s more recent research leverages machine learning to identify pretreatment predictors of symptom improvement in psychotherapeutic and pharmacological treatments for depression. Greater knowledge of variables predicting better or worse treatment response prior to the start of treatment may have important clinical implications regarding which interventions are best suited for whom, thus informing treatment selection. - ## Profile Type [Faculty](/profile-type/faculty)
