Nicholas Hartman

Nicholas Hartman is a Research Assistant Professor in the Department of Biostatistics at the University of Michigan School of Public Health, affiliated with the Kidney Epidemiology and Cost Center (KECC). His work develops statistical methodologies for survival analysis, clustered data, and healthcare provider profiling with direct applications to kidney disease and transplantation research.

Education:

• PhD in Biostatistics, University of Michigan, 2023
• MS in Biostatistics, University of Michigan, 2021
• BS in Biometry and Statistics, Cornell University, 2019

Research Focus: Dr. Hartman specializes in methodological biostatistics with emphasis on survival analysis for complex data structures, clustered/correlated data methods addressing unobserved confounding, and healthcare provider profiling frameworks. His research is driven by critical challenges in end-stage renal disease, organ transplantation access, health equity, and health policy evaluation, often involving collaboration with clinicians and policymakers.

Publication Trends: His 12 recent articles (2018-2025) reveal a concentrated focus on statistical innovations for healthcare disparities and quality measurement. Key themes include concordance indices for policy-evaluated risk scores, privacy-preserving models for transplantation access disparities, and robust methods for clustered data in provider evaluations. His work critically examines hospital quality metrics, racial disparities in surgical outcomes, and methodological pitfalls in survival analysis.
