I’m currently pursing an MD at the University of New Mexico School of Medicine. I completed an interdisciplinary BA in Mathematics & Statistics, Physical & Natural Sciences, and Social Sciences with minors in Navajo Language & Linguistics and Chicana & Chicano Studies in 2015. I was a Visiting Student in the Dept. of Economics at Harvard's Graduate School of Arts and Sciences in 2015-2017. Most recently, I was a summer fellow at the Washington University School of Medicine Mallkinrodt Institute of Radiology.

Research Interests

Currently, I’m interested in developing methods of feature extraction of medical imaging studies of tumor lesions to predict the presence of pathogenic variants, patient survival, and clinical presentation. Additionally, I’m interested in exploiting high variance in disease treatment methods to develop models of the latent biochemistry of disease using vital signs, laboratory results, and clinical presentation. I also am working on projects that address issues of diversity in medicine.

My research documented growing disparity in the rates of tissue plasminogen activator (tPA) utilization in rural and urban hospitals and the effectiveness of Primary Stroke Center accreditation in closing the gap. I have also shown substantial variation in rates of health insurance coverage among different Latino groups; there is significant variation in relationships between the likelihood of having health insurance and factors such as immigration status; and that reductions in coverage disparities among Latinos as well as between Latinos and Whites were concurrent with implementation of the Affordable Care Act (ACA) and Medicaid expansion.

Working papers

Gonzales, S, Ballejos, M & Sápien, R. Sources of bias in Holistic Review: Application to Medical School.

We use a within applicant variation to identify the causal impact of MCAT and GPA on admissions committee members' impressions of applicant. We then correlate this effect with socio-demographic characteristics of applicants to identify systematic bias in the rank and review methodology for applications to medical school.

Gonzales S & Hartley R. Remediation versus Repeating Medical Doctorate Curriculum

We use a multidimensional regression discontinuity design to estimate the treatment effect of repeating versus remediation examination for failed first year coursework on second year performance and board certification exams.
