Maria Teresa Ortiz

Data Scientist & Lecturer

I am a data analyst with experience in marketing research and ecology. I currently work at Kantar doing software development with R. Before that, I worked at CONABIO (Mexico’s National Commission of Biodiversity) doing statistical analysis related to biodiversity.

I have participated in two Mexican Electoral Quickcounts, in 2021 as Technical Committee Member, and in 2018 as Technical Committee Collaborator.

I also enjoy teaching. I teach statistics courses to master students in Data Science and to bachelor/undergraduate students in Mathematics and Actuarial Sciences at ITAM.

Lastly, I ❤️ R, I am co-organizer of R-Ladies CDMX. I volunteer with the Mexican Community of Bioinformatics Software Developers CDSB teaching R. And I deliver custom R training (introduction to R, survey data analysis in R, data science with R,…).

COURSES

Foundations of Statistics (Spanish)

I teach a course in Foundations of Statistics for the master program in Data Science at ITAM. Felipe González and I developed the syllabus and we created the class notes along Alfredo Garbuno. Here is the latest course site and here is the GitHub repository with the class notes.

Computational Statistics (Spanish)

I teach a course in Computational Statistics for the master programs in Data Science and in Computer Science at ITAM. Felipe González and I developed the syllabus and I developed (and yearly update) the class notes. Here is the latest course site and here is the GitHub repository with the class notes.

Multivariate Statistics (Spanish)

In 2014 and 2015, I taught a course in Multivariate Statistics (covering Bayesian Networks, Markov Random Fields HMMs, hierarchical models,..) for the master program in Data Science at ITAM. Felipe González and I developed the syllabus and the class notes. I am in the process of updating the course resources, here is the course site and here is a Github repository with class notes.

Introduction to R for data analysis (Spanish)

Notes for a 2-3 day introductory workshop to R for data analysis. Here is the latest workshop site and here is the GitHub repository. I have taught this workshop (sometimes as part of a larger program) at RMB, ITAM, CONABIO, SAI, OXFAM Mexico, GNP and COLMEX.

Exploratory Data Analysis and Survey Sampling (Spanish)

I taught a course in Exploratory Data Analysis and Survey Sampling for bachelors in Mathematics and Actuarial Sciences at ITAM. I am in the process of uploading the material (developed by Felipe Gonzalez).
