Ph.D. Thesis

Computer-Supported Coaching at Scale

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.

Improving Human-Autonomous Vehicle Interaction in Complex Systems

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.

Seamless and Efficient Interactions within a Mixed-Dimensional Information Space

Ph.D. Dissertation 2025Mediated by today's visual displays, information space allows users to discover, access and interact with a wide range of digital and physical information. The information presented in this space may be digital, physical or a blend of both, and appear across different dimensions - such as texts, images, 3D content and physical objects embedded within real-world environment.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel.

Sensing, Understanding, and Augmenting - Methods for Enhancing Human Behavior Analysis using Computational Sensing and Social Signal Processing

Ph.D. Dissertation 2025From fine-grain filtering of noise required to selectively attend to a specific person in a social setting, to the rapid visual pattern recognition required for complex tasks like radiological diagnosis, human perceptual and cognitive systems are capable of incredible things. Built up over years of evolution in a physical world, people have developed wonderful abilities.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel.

Advancing Support for XR-Mediated Remote Collaboration on Physical Tasks

Ph.D. Dissertation 2023Technology-mediated collaboration for physical tasks -- where a novice manipulates real objects in their space with the guidance of a remote expert -- helps extend expertise to remote and often resource-strapped environments. The spatial and immersive nature of emerging technologies like eXtended Reality (XR) promise to make this collaboration more natural and intuitive in ways that traditional screenbound collaborative systems can't.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel.

Designing for misalignment in Augmented Reality displays: Towards a Theory of Contextual Aids

Ph.D. Dissertation 2023Augmented Reality (AR) displays show virtual information spatially in the physical world. For example, in the surgical domain, AR displays can overlay medical imaging on top of the patient to help surgeons distinguish healthy tissue from cancerous tissue.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel.

eXtended Reality Support for Invasive Medical Procedures with Enhanced 3D Imaging

Ph.D. Dissertation 2023Invasive medical procedures are essential in healthcare, but clinicians can only be effective in performing them when they are able to precisely understand an individual patient's anatomy. While training and multi-year experience form the basis for any medical procedure, individualized medical imaging plays a critical and continuous role across both the educational context and the everyday practice of these procedures.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel and Jürgen P. Schulze.

Human-Centered Machine Learning for Healthcare: Examples in Neurology and Pulmonology

Ph.D. Dissertation 2020Machine learning (ML) in healthcare has enabled the automatic detection of diseases from medical images or sensors with high accuracy, often outperforming domain experts. Unfortunately, there is a large variance between how such diagnostic aids perform in research settings and in the real-world.Ph.D. Dissertation, UC San Diego. Advised by Nadir Weibel and Gert Cauwenberghs.
