Zachary L. Stickley
Hello there!Thank you for stopping by and checking out my work! I received my Ph.D. in Educaitonal Psychology in 2022 from Texas Tech University while studying in the Educational Psychology: Research Methods, Evaluation, Measurement and Statistics (REMS) program in the College of Education under Dr. Todd D. Little.
I received my Bachelors of Science degree in Psychology from Tarleton State University and have participated in a two-year research internship at the VISN 17 Center of Excellence for Research on Returning War Veterans located at the Doris Miller VA Medical Center in Waco, Texas.I am currently working as a senior research scientist for Yhat Enterprises LLC., and have worked a coordinator and instructor for the Stats Camp Foundation. Most of my work involves imputation of missing data and longitudinal latent variable modeling, but I also help researchers design and administer surveys in Qualtrics, particularly when it comes to implementing a planned missing data design. I also do a fair amount of methodological consulting to graduate students and post-graduate researchers around the world!My current research interests include latent variable modeling, survey design including planned missing data designs, and modern missing data treatments. I also enjoy collaborating with other researchers and helping them tell their stories with their data!
