Fordham_Martinez

I am a quantitative psychologist and my research is focused on the development and application of statistical algorithms (primarily Bayesian) for cognitive diagnosis models and other psychometric/latent variable models. Most of my computational work involves evaluating the performance of these algorithms via simulation studies under conditions common in education and psychological research. I am the Director of The PRISM Lab at Fordham University (https://www.theprismlab.ajmquant.com/) which is dedicated to the development of quantitative and statistical methods and their applications to the social and behavioral sciences. The PRISM lab conducts research in the following subject areas: Generalized latent variable and psychometric modeling (e.g., generalized structural equation models, cognitive diagnosis models, factor analysis, item response theory); Bayesian inference, modeling, and prediction; Mixture modeling; Measurement invariance, adaptive testing, and psychological/educational measurement; Estimation theory for psychometric and generalized latent variable models; Multilevel and longitudinal modeling; Computational statistics as applied the psychological, behavioral, and social sciences.
