We are a diverse group of researchers, scientists and medical professionals.


Naima Health was spun out from Carnegie Mellon University and the University of Pittsburgh to develop and commercialize the MyHealthyPregnancy app. Our team of leading decision scientists, machine learning specialists, and maternal-fetal health clinicians created this tool to help pregnant women minimize their risk of adverse pregnancy outcomes – including preterm birth. We additionally apply our multidisciplinary approach to jointly develop strategies and products to enhance our partners' business.



Tamar Krishnamurti, PhD | Founder + CEO

Dr. Tamar Krishnamurti's research uses quantitative and qualitative methods to conduct both basic and applied research on interests including risk perception and communication, medical decision making, mHealth, and the design of effective communications, decision aids, and interventions for both domestic and international populations. Her work has focused on vulnerable and high-risk social groups.  

Dr. Krishnamurti received her PhD in Social and Decision Sciences from Carnegie Mellon University. She is an Assistant Professor in the Division of General Internal Medicine at the University of Pittsburgh, with an adjunct faculty position in the Department of Engineering and Public Policy at Carnegie Mellon University.


Alex Davis, PhD | Founder + CTO

Dr. Alex Davis' research focus has been to create innovative analytical methods for use in decision and policy analysis, deepen the basic science of decision-making, and contribute to applications where technology plays a central role in human decision-making. He has contributed to quantitative methods of experimental design that integrate expert judgment with statistical learning, implemented a meta-analytic approach that quantitatively integrates studies with heterogeneous quality, and has advanced methods of nonparametric graph-learning. 

Dr. Alex Davis received his PhD in Social and Decision Sciences from Carnegie Mellon University. He is an Assistant Professor in the Department of Engineering and Public Policy at Carnegie Mellon University.


Hyagriv Simhan, MD, MS | Founder
