Quantitative Research Collaboratory

The Quantitative Research Collaboratory (QRClab) is a team of researchers working on projects which improve and expand quantitative methods and research practices in psychology (and related) research. Projects in the lab focus on implementation and analysis of repeated-measures design, open science practices, meta-science, and computational statistics (e.g., bootstrapping). New projects on new topics are always welcome!

The QRClab is seeking graduate students and undergraduates to contribute to the research in this lab. Students will begin on a collaborative project with direct contact with the Principal Investigator, and transition to greater independence as experience and desire dictate.

Research from the QRClab was recently featured on Quantitude: The Podcast Season 2 Episode 1 and Season 3 Episode 9. Honors student Kathleen Lamarque-Navarrete's research in collaboration with Dr. Jennifer Sumner, explores the use of propensity scores in recruitment of participants for cohort studies. 

Congratulations QRC Research Assistant, Kathleen Lamarque-Navarrete, who has been accepted into the Departmental Honors program in Psychology!

Congratulations Charlotte Huang who won the 2020 UCLA Library Prize in Science, Engineering, and Math!

Research Highlights

Get Involved

Graduate Students: Please email me if you are interested in getting involved in the lab. I will be accepting applications for PhD students for Fall 2024. GREs are optional for admissions to the PhD program at UCLA. Quantitative psychology is by definition very reliant on quantitative skill sets which can be demonstrated in a number of ways: performance in mathematics courses, performance on the quantitative section of the GRE, and/or letters of recommendation speaking to your quantitative expertise. When reading applications we will look for demonstrated ability in quantitative skills, but this should not require a GRE score if other parts of your application speak to these skills. If you are unsure whether you should or should not include GRE scores in your application to UCLA, please feel free to contact me. Matrix algebra is an important part of statistics and quantitative psychology. Formal or informal education in this area is important for admission to our lab and program. If you have not been able to take a formal course in matrix algebra, see these resources for ways to gain informal education on the topic: Matrix Algebra Preparation.

See the Department Website for more information about the application process. 

Undergraduate Students:  Please email the lab if you are interested in getting involved in the lab. Include a resume/cv, your UCLA transcript, and fill out this application
