Background: Dr. Mahometa received his Ph.D. in Psychology from The University of Texas at Austin in 2006. His major course work was completed in Behavioral Neuroscience, with a minor in Statistics. His background in animal models of learning makes him familiar with full factorial designs - which he is expanding to include classic DOE concepts. He is currently available to assist graduate students and faculty in study methodology, data analysis, data presentation, and result writing. He is most familiar with the following statistical software packages: SPSS, SAS, Stata, JMP, StatView, SuperANOVA.
Education: Ph.D., Psychology, University of Texas at Austin, 2006; B.S., Psychology, University of Scranton, 1998

Background: Sally received her Master of Science degree in Statistics from the University of Texas at Austin in 2012. For her Master’s Report, she wrote a program in R which calculates the linear model estimates for bivariate data with correlated measurement errors. Prior to graduate school, she worked for four years as a statistical analyst for a survey research company specializing in transportation survey analysis. She is most familiar with the R, SPSS, and Stata statistical software packages, but also uses Matlab and SAS.

Background: Erika received her Master of Science degree in Statistics from Florida State University in 1993. After graduating, she joined Merck, Inc. as a statistician on Phase I, II, and III clinical trials. She then worked for a contract research organization on numerous statistical projects clients in the pharmaceutical industry. She has been a statistical consultant for the Division of Statistics and Scientific Computation since September, 2007 and has taught SPSS for the UT Summer Statistics Institute. Erika is most familiar with the SPSS, Stata, and SAS statistical packages but also uses R.

Background: Prasad Buddhavarapu is currently pursuing PhD in Transportation Engineering. He is also pursuing another M.S. degree in statistics in parallel to the Phd program. His doctoral work is in road safety management, particularly crash frequency and severity modeling. He works on negative binomial regression models incorporating spatial and temporal correlations under Bayesian hierarchical modeling framework as part of the Ph.D. dissertation. He enjoys building statistical models that facilitate learning useful information from obscure datasets. He is most familiar with the following statistical software packages: R, SPSS, Stata but also uses SAS.
Education: M.S., Civil Engineering, University of Texas at Austin, 2012; B.S., Civil Engineering, National Institute of Technology, India, 2008
