Past Trainee/Staff - Tapan Mehta

Tapan Mehta Statistician II
Department of Biostatistics
University of Alabama at Birmingham
Birmingham, AL 35294
Current Location

Tapan received his M.S. degree in Electrical Engineering from the University of Alabama at Birmingham (UAB) with a specialization in software engineering in 2004. Before joining the computing team at the Section on Statistical Genetics (SSG) at UAB, he worked as a graduate research assistant at SSG and pursued his Masters thesis in the area of stability of clustering algorithms. He was also involved in several genomic data analyses, publications, and leveraging high performance computing solutions. As a statistician his responsibilities include leading and participating in several data analyses and methodology development projects, provide sound high performance computing and software engineering support to these projects. Scientific scope of these projects range from obesity-related epidemiological projects to genomic and genetic data analyses projects related to obesity and cancer.

Currently, he is also pursuing his doctoral degree in Biostatistics at UAB under the mentorship of Dr. David B. Allison. Tapan's interests lie in aggregating and integrating silos of genomic and epidemiological data, to investigate interesting scientific questions, through novel applications of statistical methods and computing platforms. He is especially interested in the use of longitudinal and meta-analytic frameworks, risk prediction and bayesian hierarchical modeling.
