Linda Tomasso - Dissertation Defense - Investigating an Affinity for Nature as a Determinant of Nature Use and Health Benefits,

Congratulations to Linda Powers Tomasso who successfully defended her dissertation, “Investigating an Affinity for Nature as a Determinant of Nature Use and Health Benefits” on April 25, 2022. Linda joined the department in 2017 under the supervision of Jack Spengler and has researched the emotional and cognitive benefits of nature from a mixed-methods approach to exposure assessment. Her work brings qualitative insights into a discipline typically quantitatively focused to understand the origins of nature-seeking behavior, social and structural barriers to nature engagement, and the impacts of these factors on equitable nature access. Linda was the first author on numerous publications and most recently “The Relationship between Nature Deprivation and Individual Wellbeing across Urban Gradients under COVID-19” which was published in the International Journal of Environmental Research and Public Health. She recently conducted a novel museum-based experiment to assess stress reduction from live nature vs landscape paintings for use in institutionalized settings.

Linda will continue her research as a post-doctoral Research Fellow with Jack Spengler.

Restless legs syndrome severity in the National RLS Opioid Registry during the COVID-19 pandemic

Master of Science student Chris Romero-Gutierrez was co-author on a recent article in the Sleep Medicine Journal, Restless legs syndrome severity in the National RLS Opioid Registry during the COVID-19 pandemic. The research hypothesized that Restless Leg Syndrome (RLS) symptom severity would be increased during the COVID-19 pandemic in a sample of patients with diagnosed RLS and participants with increases in RLS severity were significantly more likely than others to see increases in sleep disturbance, depression, and anxiety.

Mortality Attributable to Long-Term Exposure to Ambient Fine Particulate Matter: Insights from the Epidemiologic Evidence for Understudied Locations

PhD Student Kyle Colonna was first author in the Environmental Science & Technology Journal article “Mortality Attributable to Long-Term Exposure to Ambient Fine Particulate Matter: Insights from the Epidemiologic Evidence for Understudied Locations“. Researching how long-term exposure to ambient fine particles (PM2.5) has been consistently associated with mortality. This critical review discusses the evidence for (i) the associated risk of mortality, (ii) the shape of the concentration response function, (iii) a causal interpretation, and (iv) how the source mix/composition of PM2.5 and population characteristics may alter the effect.
