arXiv preprint 2025Despite the parallel challenges that audio and text domains face in evaluating generative model outputs, preference learning remains remarkably underexplored in audio applications. Through a PRISMA-guided systematic review of approximately 500 papers, we find that only 30 (6%) apply preference learning to audio tasks.
Technical Report 2025This report presents findings from a comprehensive survey of commercial fleet professionals involved in fleet safety (specifically managers, coaches and decision-makers) regarding the perceived effectiveness, practical implementation, and strategic value of different driver coaching approaches. Grounded in the broader objective of improving safety outcomes through evidence-based coaching strategies, the survey sought to explore both individual preferences and organizational practices.The survey respondents consisted of two distinct groups: individuals who identify coaching as a key part of their primary job, and commercial dashcam decision-makers who do not directly engage in driver coaching.Technical report, not peer reviewed.
UIST Adjunct 2025Using head-mounted Virtual Reality (VR) displays to simulate driving is critical to study driving behavior and design driver assistance systems. But existing VR driving simulators are often limited to tracking only eye movements.
Ph.D. Dissertation 2025In today’s dynamic labour market, continuous re-skilling helps people adapt when changing jobs. Coaching can help people overcome plateaus when learning new skills that are needed for these new jobs.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel.
JMIR Research Protocols
The rising prevalence of mental health concerns among students is prompting universities to explore innovative solutions to support student well-being. This paper describes the protocol for the development, implementation, and evaluation of the Willo mobile app designed to address the mental health and wellness needs of students.
Technical Report 2025This report critically evaluates coaching methodologies for enhancing fleet driver safety, engagement, and overall organizational performance. Drawing on empirical research across education, behavioral science, and fleet management, this analysis identifies key dimensions of effective commercial driver coaching, highlights significant limitations of current practices, and outlines strategic recommendations focused explicitly on differentiation and optimization.Technical report, not peer reviewed.
ISRII 2025Poster presentation on grounding large language model responses to in-the-moment distress in the skills and principles of Dialectical Behavior Therapy, so that just-in-time support follows clinical theory rather than generic conversational patterns.Poster presentation, International Society for Research on Internet Interventions, San Diego, CA.
JAMIA 2025Clinician implicit bias can impede patient-centered communication, leading to health care inequities. While the field of implicit bias education is evolving with advances in technology, clinicians’ perspectives remain underexplored.
Stroke 2025Augmented reality enables visualization of and interaction with both physical and virtual environments. Holograms can allow 3‐dimensional image transmission to distant sites, allowing patients to interact with providers as if in the same space. Our prior publication resulted in high satisfaction/immersion for patients interacting with Holo‐Stroke providers. Our aim here was to determine if providers assessing computed tomographic angiographies (CTAs) for large vessel occlusion would result in reliability and satisfaction.
Ph.D. Dissertation 2025Advances in Autonomous Vehicle (AV) technology promise significant individual and societal benefits. However, unresolved questions about how to meet the informational needs of riders hinder real-world adoption.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel and David Kirsh.
