I am dedicated to increasing access to research, open science, and bridging the research-clinic divide. That's why, whenever possible, I have provided self-archived (free) versions of research articles, links to the published articles, as well as any repositories with corresponding data and analytic code. 

During a voice evaluation, clinicians often visually assess vocal fold mobility through a series of repeated "sniff-ee" maneuvers that elicit maximum vocal fold abduction. This task can provide quantifiable information (i.e., glottal angle), but clinicians must rely on subjective visual assessment due to the time and labor required to manually measure glottal angle frame-by-frame. We manually measured maximum glottal angle abduction across five voice disorders and found that although maximum glottal angle abduction did not differ across the groups, participants with laryngeal dystonia, essential tremor, and inducible laryngeal obstruction/paradoxical vocal fold motion disorder displayed significant more variability in their maximum glottal angle measures across repeated trials. These data will inform a larger project aimed at developing an artificial intelligence tool to track glottal angle. 

For decades, some have proposed that a subset of people are physiologically predisposed to manifesting emotional distress in their larynx – i.e., "laryngoresponders" (LRs) However, to date, very few studies exist seeking to characterize or understand so-called LRs. We recruited 995 participants and asked them to report how they experience stress in their body, modeled on previous chronic pain measures. We found that about 16% of people are self-identified LRs. We also found that those who report laryngo-centric stress manifestation were significantly higher in measures of recent perceived stress and childhood trauma. This paper expands upon our previous pilot data and represents one of the most extensive investigation into so-called LRs to date.

This paper measured communicative congruence (CC), or how well one's sense of self aligns with their voice and speech, in a sample of individuals without voice disorders. Notably, in a sample of 196 mostly cisgender participants, we found that people generally reported higher levels of CC than what we had hypothesized. However, even in a sample with a relatively higher sense of congruence, we found that CC had a significantly inverse relationship with depression, as we had hypothesized. This paper is the first investigation into CC and provides preliminary evidence to support the notion that feeling a sense of incongruence can have negative effects on one's well-being. 

Laryngoresponders (LRs) are thought to be physiologically and/or psychologically predisposed to respond to stress in their larynx. To date, few research studies have sought to examine or develop methods to identify LRs. In this study, we developed a preliminary self-report measure modeled on chronic pain measures. In a cohort of 29 vocally healthy cisgender women, we found that six (21%) self-reported laryngeal symptoms due to stress. The LR group reported significantly worse scores on childhood trauma variables compared to the non-LR group. 

Previous studies have demonstrate that both pitch and formant frequencies influence listeners' perceptions of a speaker's gender. These studies have largely been done in cisgender speakers and transfeminine speakers. Less research exists examining how these factors influence gender perception in transmasculine individuals. This study used speech resynthesis of three transmasculine individuals for before and after hormone replacement therapy to examine which components of the speech signal had the largest influence. 

Whether you like it or not, you probably start to make judgments about a person as soon as they start to speak. Across two experiments, we asked listeners to rate the personality traits of speakers. Generally, listeners tend to agree with other listeners on their judgments of a speaker (high other-other agreement), even though listeners' ratings tended to not be "accurate" (low self-other agreement). 

Prior research has used fine-wire electromyography (EMG) to measure intrinsic laryngeal muscle activity during acute psycho-social stressors. Yet, it is possible that the increased muscle activation observed during these stressors were due to subvocalization associated with the linguistic nature of the stressor tasks. This study compared the effect sizes of muscle activity during subvocalization to the previously reported muscle activation during the stressor tasks. Overall, the effect sizes of most of the muscle activation observed in the subvocalization tasks were negligible, with a handful of effect sizes achieving a small effect. These findings provide empirical evidence for the methodology of future fine-wire EMG intrinsic laryngeal muscle activity. 

In this qualitative study, we examined how young Latino/a adults with multiple intersecting marginalized identities conceptualize and experience structural stigmas and their influence on mental health. This study highlights the importance of leveraging an intersectional minority stress framework for studying mental health inequities.
