Rosi Kaiser, PhD

CREST

Dr. Roselinde Kaiser is a clinician and clinical neuroscientist who joined the Dimidjian lab in 2008 as one of the first dual-doctoral students in Clinical Psychology and Neuroscience. Dr. Kaiser completed her clinical internship at Yale University from 2012-2013, and after receiving her Ph.D. in 2013, Dr. Kaiser joined the Pizzagalli lab at Harvard Medical School/McLean Hospital as a Postdoctoral Fellow. Dr. Kaiser’s research interests are centered on exploring cognitive-affective dysfunctions in depression, and how they relate to anomalies in the coordinated recruitment or functional connectivity of large-scale neural networks. Moreover, as a clinical researcher, Dr. Kaiser is especially interested in how neural network dysfunction relates to risk for, and maintenance of, psychopathology, and how enhancement of cognitive-affective abilities may normalize network functioning and foster psychological health. During her graduate student career, Dr. Kaiser conducted and collaborated in research to investigate deficits in executive functioning that may underlie rumination or negatively biased cognition1-6. Results of this research suggested that in a negative emotional context, e.g., after being criticized by a loved one6 or when viewing negative words5, people who tend to ruminate or who are more severely depressed may have difficulty shifting attentional resources away from internal thoughts and towards the external world.  Critically, research findings suggested that this inwardly-focused attentional bias was reflected in increased activation in brain systems involved in internal mentation, and increased functional connectivity between attention-control and internal-mentation networks5. However, Dr. Kaiser and colleagues also found evidence for increased resilience to the distracting influence of negative emotional information in people higher in mindful decentering, suggesting that the ability to observe, accept, and let go of negative thoughts is important in protecting healthy cognitive functioning in the face of emotional events6. As a Postdoctoral Fellow, Dr. Kaiser continues to engage in clinical work and research exploring cognitive-affective functioning and the pathophysiology of depression.
