  • Constantine Frangakis, PhD
  • Professor of Biostatistics at the Johns Hopkins Bloomberg School of Public Health

Dr. Constantine Frangakis develops designs and methods of analyses to evaluate treatments in medicine, public health and policy (causal inference). The increased quality and number of available treatments, and increasing ethical and practical constraints, are transforming the field of intervention research: the factors of research interest are no longer (and correctly so) the same as factors that we can intervene on humans. To address this, we have been developing new designs and methods for partially controlled studies, studies that explore the factors that can be controlled, in order to investigate the effects of the factors of research interest.
