OverviewAI-generated summary

Ellen W. Leen‐Feldner, Professor and Vice Chair at the University of Arkansas at Fayetteville, investigates the effects of various substances, particularly cannabidiol (CBD), on human anxiety, withdrawal symptoms, and emotional states. Her recent work includes a double-blind, randomized placebo-controlled trial examining CBD's impact on worry and anxiety in individuals with high trait anxiety, as well as a study on the use patterns and perceived effects of hexahydrocannabinol cannabis products. Leen‐Feldner has also explored the effects of acute sleep deprivation on affect and avoidance behaviors. Her research often employs rigorous experimental designs, including randomized controlled trials and double-blind placebo controls, to assess the efficacy and practical considerations of pharmacological interventions for psychological conditions.

Her scholarship metrics include an h-index of 36, with 114 total publications and 3,487 total citations, designating her as a highly cited researcher. Leen‐Feldner actively collaborates with colleagues at the University of Arkansas at Fayetteville, including L. Riley Gournay, Matthew T. Feldner, Morgan A. Hill, and Morgan L. Ferretti, with whom she has co-authored multiple publications. She maintains an active lab website, suggesting ongoing research and potential opportunities for engagement.
