BioMy research as a climate scientist seeks to understand the physical processes that shape the polar regions. The high latitudes are undergoing the largest changes on Earth; in recent decades, Arctic temperatures have warmed at twice the global average, while 2023 featured the lowest Antarctic sea-ice extent on record. Policymakers’ ability to manage the consequences of these changes requires improved polar climate predictability. Rapidly declining Arctic Sea ice exposes new economic resources and shipping routes, necessitating a detailed understanding of where and how quickly newly open water will appear. In the Antarctic, the instability-prone West Antarctic Ice Sheet may have large future contributions to sea-level rise, but predicting the timing and magnitude of ice sheet melt requires a better understanding of how Antarctic warming trends will progress. To address these scientific priorities, my research characterizes ocean-ice sheet interactions, ventilation of the deep ocean, and coupled atmosphere-ocean variability, among other phenomena. A common theme across my work is the use of data-driven techniques to reconcile discrepancies between models and observations, identifying key areas for improving future generations of climate models.

Makoto Kawai
Clinical Professor, Psychiatry and Behavioral Sciences - Sleep Medicine
BioI am a physician scientist in the field of sleep medicine in aging and brain function. Using combined polysomnogram and novel neuroimaging technology, I aim to identify potential sleep biomarkers to investigate the mechanism of progression from normal aging to Mild Cognitive Impairment (MCI) or dementia. I also investigate the impact of sleep on cognitive/affective function or behavior abnormality in various neurodevelopmental and neurodegenerative disorders.

Debra Lee Kaysen
Professor of Psychiatry and Behavioral Sciences (Public Mental Health and Population Sciences)
Current Research and Scholarly InterestsMuch of my current research focus is on the development of testing of accessible, scaleable, and effective treatments for trauma-related disorders and related comorbidities (e.g. substance use disorders, HIV, mood disorders). This work has focused on addressing trauma-related disorders especially in underserved populations and settings. This includes research in rural communities, with Native American communities, and with sexual minorities. My research has had a strong impact on building an evidence base on adaptations of psychotherapies for PTSD and substance use disorders for diverse populations both within and outside the United States. Our findings demonstrate that complex cognitive behavioral psychotherapies like Cognitive Processing Therapy can be culturally adapted and delivered in challenging settings (conflict settings, high poverty environments) with significant and lasting change in PTSD, depression, and functioning. This has led to work adapting CPT for diverse populations within the United States (rural Native Americans, urban Latinos) and outside of it (Iraq, DRC). Other research has focused on treatment for PTSD/SUD. My research has also found support for the use of brief telehealth interventions to build treatment engagement and to reduce drinking among trauma-exposed populations. In addition, my work has been critical in testing the feasibility of novel trauma-focused interventions for use by those with PTSD and SUD, thus paving the road for more rigorous research studies.
Current PI'ed research studies include: 1) developing and evaluating a brief motivational interviewing intervention designed to increase treatment-seeking among military personnel with untreated PTSD; a two-arm randomized comparative effectiveness trial to evaluate prevention of HIV/STI sexual risk behavior by addressing PTSD through Narrative Exposure Therapy or substance use through Motivational Interviewing among Native American men and women with PTSD; and 3) a comparison of outcomes among patients randomized to initially receive pharmacotherapy or Written Exposure Therapy delivered in primary care as well as comparing outcomes among patients randomized to treatment sequences (i.e., switching and augmenting) for patients who do not respond to the initial treatment. -
