About Me (CV)
I’m a Computer Science and Engineering PhD Candidate at the University of Michigan working with Professors Jenna Wiens and David Fouhey. I’m also a visiting academic at NYU. My research centers on developing AI tools to augment human decision making, inspired by problems in healthcare. I develop machine learning and computer vision techniques for improving AI generalization under distribution shift. In addition, I develop methods for improving human-AI collaboration (e.g., new generative AI-based explanation tools) and study how humans use such tools to make decisions through large-scale user studies.
I did my undergrad at the University of Michigan, where I received my BSE in Computer Science and Engineering and my BBA from the Ross School of Business.
In my free time, I love spending time outside of the lab & very far away from my computer. You’ll generally find me at the gym weightlifting, baking (mostly croissants, sometimes cakes), or learning new instruments.

DEPICT: Diffusion Enabled Permutation Importance for Image Classification Tasks
Sarah Jabbour, Gregory Kondas, Ella Kazerooni, Michael W. Sjoding, David Fouhey*, Jenna Wiens*. ECCV 2024. [Project page] [ArXiv] [PDF] [code]
Permutation feature importance has been used to explain tabular-based models. We extend this to images via text-conditioned diffusion to generate dataset-level explanations for image-based models!
Measuring the Impact of AI in the Diagnosis of Hospitalized Patients:A Randomized Clinical Vignette Survey Study
Sarah Jabbour, David Fouhey, Stephanie Shepard, Thomas S. Valley, Ella A. Kazerooni, Nikola Banovic, Jenna Wiens*, Michael W. Sjoding*. JAMA 2023. [Link]
AI model explanations have been proposed to mitigate the harmful effects of innacurate AI, but the utility of such approaches have not been tested. We ran a survey study across 13 states and 450+ clinicians, showing that AI model explanations don’t help clinicians recover from the negative impact of innacurate AI.
Learning Concept Credible Models for Mitigating Shortcuts
Jiaxuan Wang, Sarah Jabbour, Maggie Makar, Michael W. Sjoding, Jenna Wiens. NeurIPS, November 2022. [PDF]
Models can take shortcuts due to spurious correlations and perform poorly out of distribution. We propose a regularization penalty that incorporates domain knowledge to encourage models to use known concepts over unknown, potentially spurious concepts.
Combining chest X-rays and electronic health record (EHR) data using machine learning to diagnose acute respiratory failure
Sarah Jabbour, David Fouhey, Ella Kazerooni, Jenna Wiens, Michael W. Sjoding. JAMIA, March 2022. [PDF] [Code] [Bibtex]
Accurately identifying what is causing a patient’s acute respiratory failure (shortness of breath) is difficult, but essential for determining appropriate treatment. We built a model that can predict the common causes of respiratory failure (pneumonia, heart failure, and/or COPD) based on patients’ chest X-rays and clinical data.
Augmenting existing deterioration indices with chest radiographs to predict clinical deterioration
Emily Mu, Sarah Jabbour, Adrian V. Dalca, John Guttag, Jenna Wiens, Michael W. Sjoding. PLOS ONE, February 2022. [Paper]
Augmenting existing deterioration indices with chest radiographs results in better identification of low-risk patients. The model augmentation strategy could be used in the future to incorporate other forms of unstructured data into existing disease models.
Respecting Autonomy and Enabling Diversity: The Effect of Eligibility and Enrollment on Research Data Demographics
Sarah Jabbour, Kayte Spector-Bagdady, Shengpu Tang, W. Nicholson Price II, Ana Bracic, Melissa S. Creary, Sachin Kheterpal, Chad M. Brummett, Jenna Wiens. Health Affairs, December 2021. [PDF]
AI/Big Data rely on large datasets, but these datasets are generally populated with demographically homogeneous cohorts. We studied how recruitment and enrollment approaches at a major academic medical center affect the demographic diversity of its research biospecimen and data bank. Compared with the overall clinical population, patients who ended up in the research data bank were significantly less diverse due to both recruitment and enrollment. We need a systemic commitment to diversify data banks so that different communities can benefit from research.
Deep Learning Applied to Chest X-rays: Exploiting and Preventing Shortcuts
Sarah Jabbour, David Fouhey, Ella Kazerooni, Michael W. Sjoding, Jenna Wiens. MLHC, August 2020. [PDF] [Code] [Video] [Bibtex]
Deep learning models are easily susceptible to the use of features that do not directly cause disease, but rather are correlated with disease in the training population. Since these features may not transfer across populations, we developed an approach to encourage models to use clinically relevant features in the data.
