Curriculum Vitae Publications Email
I am formally trained as a quantitative psychologist and have the expertise and training to conduct the proposed analyses. At my university, I have taught courses in regression, experimental design, test theory, multivariate statistics, multilevel modeling and latent variable modeling and I am my department’s primary methodologist. I have published manuscripts using multilevel modeling, item response theory, latent variable models and regression techniques. Below is a sampling of some of my more methodological publications.

Early in my career, I studied multi-criteria decision making and was recognized for this work (see above). Research for the last 60 years has shown that statistical (or actuarial decision making) outperforms judgments of expert judges. Along those lines, I am interested in assessing whether multi-criteria decisions need to be disaggregated into smaller parts, much like an actuarial decision. I am extending this interest in developing decision aids, based on the principle of decision disaggregation, to help patients make informed decisions about their health care.

I also identify myself as an applied psychometrician with interests in measurement invariance, test validation and methodology. I am primarily interested in ensuring that measures operate or function similarly across groups of individuals. The research articles I have published involve minority-related research, especially with Hispanic populations and the journals where these findings are published are relevant to their audiences.

I also use my quantitative training to evaluate interventions. Earlier in my career, I helped evaluate a smoking cessation intervention program that was focused on assisting women with a high school education or less quit smoking. We also developed an after school exercise program geared toward Mexican American children in El Paso that promoted both physical activity and learning how to identify healthy foods. The program was culturally adapted and several papers resulted from this intervention. We also conducted a survey of 1002 Hispanic households in El Paso to identify how health care is utilized in a border city.
