Katherine is interested in the intersection of memory and emotion in clinical PTSD and GAD populations. Anxious individuals often experience intrusive, emotional negative memories; strong emotional responses to possible future events; and heightened emotional responses to potential threats. Her research focuses on investigating the cognitive processes that underpin emotional memory, with the intent of identifying the neural and behavioral mechanisms that produce these maladaptive behaviors.

She is exploring the role of fear generalization—the attribution of threat to neutral or safe stimuli that bear a strong resemblance to threat stimuli—in anxiety disorders. Specifically, she aims to study population differences in the neural and behavioral processes thought to be involved in fear generalization, such as pattern completion and pre-frontal inhibition of the amygdala threat circuit, which may be implicated in maladaptive enhanced fear generalization in anxiety disorders.
