Dr. Prathiba Natesan Batley's curriculum vitae [PDF]


I specialize in statistical simulation, Bayesian methods, single case designs, and latent variable modeling. My interests are in the development and application of statistical methods for the social, medical, business, and biological sciences.

I am a methodologist and statistician who specializes in developing methodological solutions to address real world data problems such as small sample cases, non-normality, dependence of observations, etc. which are generally antithetical to commonly used parametric techniques. I have worked with large data problems that involve latent variable and multilevel modelling, as well as with small data problems such as single case experimental designs which involve Bayesian interrupted time-series analyses. My interdisciplinary collaborations span across many fields such as medicine, education, geography, marketing, psychology, architecture, library sciences, and management. Recently, I have been developing Bayesian methodologies for mixed methods analyses. I am equally passionate about research and teaching statistics and believe that anyone can see the beauty of the subject with the right kind of guidance.

I am currently co-PI for an Institute of Education Sciences funded grant entitled Design Comparable Effect Sizes for Single-Case Designs for $899,721. I am also evaluator for an NSF-funded project entitled IRES: Cross-cutting interdisciplinary research and integration of ecology and biocultural conservation in the world’s southernmost forests for $249,963. In the past I have served as evaluator on a US Department of Education funded project entitled Project STArT for $1,247,881 and as senior investigator on NSF-funded project entitled Collaborative Research: Web-Based Repository of Software Testing Tools (WReSTT) for $153,930.

I have been an invited panelist on Institute of Education Sciences grants for the last five years. Currently I am statistical advisor to the British Journal of Psychiatry, associate editor of the International Journal of Multiple Research Approaches and Frontiers in Psychology: Quantitative Psychology and Measurement, and editorial board member of Journal of Research on Educational Effectiveness.
