Doctoral Level Math-Statistics-Software Tutoring and Consulting

I am a Ph.D. statistician, and I have a long experience in teaching mathematics and statistics as a university professor (grad and undergrad level) as well as a research/statistical consultant. I strongly believe that I have the skills, experience, and training required to communicate mathematical and statistical results to very diverse individuals and audiences. I am also very proud that my WyzAnt student for two consecutive years was accepted to MIT! Because of my training and experienc... [more]

Besides a long experience I have as a SAS programmer and my participation in numerous statistical projects using SAS and SAS Enterprise, I have recently passed the programming 1 and programming 2 courses (offered by SAS) so that I can more effectively help those people that are seeking SAS certification. i have also taught a University course related to experimental design with the use of SAS.


I have an extensive training in biostatistics, and in particular in topics related to worked in survival analysis, biomarkers evaluation, missing data and proportional hazards models to name a few. My experience is related to the numerous biostatistical projects that I have been involved, as a consultant, through the years and the numerous students and professionals that I have helped both with the software implementation and the analysis of the results.


I have taught logic as part of a quantitative reasoning undergraduate course and as part of a finite mathematics course. These courses include but are not limited to the discussion of statements, premises and conclusions, negation, conjection and disjunction, conditionals, necessary and sufficient conditions, contrapositive statements and equivalence. The combination of all these leads to the construction of truth tables for analyzing statements and determining their validity (tautology).


I have successfully helped numerous Praxis candidates with all of the Algebra, Geometry, Trigonometry and Calculus parts of the test. I can provide students with not only the analytical approach to the questions but also with the right strategies to ace the test. The most important such strategy is time management. To achieve the best results possible I train students to effectively use scientific/ graphing calculators such as the TI 83-84 series. By doing that the student can deliver excellent results in the minimum possible time.
