Research Interests

Currently, my research spans several exciting areas:

• Healthcare: I devise AI methods that leverage extensive datasets to assist doctors in enhancing their decision-making capabilities. For instance, I work with Booth and The University of Chicago Medical Centre (UCM) to evaluate and improve the impact of UCM's Care Management Program. Through my nonprofit Math 4 Change I work developing interpretable rules for predicting the inefficacy of tuberculosis first-line treatment in Mozambique, providing doctors with useful decision-support tools to combat this disease. Still in Mozambique, I am applying AI to unravel the determinants of low birth weight in newborns in Quelimane, potentially providing critical insights for medical interventions

• Responsible Supply Chain Management: I develop innovative AI methods and algorithms to enable responsible decision-making in supply chains. For example, I collaborate with industry to tailor and apply AI methods to mitigate food waste through optimized inventory decisions. I also work with a startup to deliver AI solutions that promote inclusivity and body positivity by providing women with a broad selection of undergarments that fit both their unique body shape and their preferences, underscoring the transformative potential of research in social norms and self-perception.

• Assessing and combating biases: I analyze large datasets to evaluate biases in human or AI-driven decisions, and I propose new AI methods to alleviate these. I’m analyzing the fairness of Israeli judicial proceedings concerning Arab cases. Since our results suggest significant disparities based on the petitioner’s ethnicity, we aim to provide equitable legal insights to support NGOs aiding Palestinian communities. I'm also interested in forging AI methods that identify and counteract biases, particularly for underrepresented minorities in personalized medicine. I have a special interest in gendered medicine, which I believe can help address the traditional underrepresentation of women in medical studies and trials, which often leads to unsatisfactory treatment healthcare delivery. I also seek to understand and devise strategies to improve healthcare delivery for Aboriginal communities in Australia, ensuring more equitable and effective medical care across diverse demographic groups.
