Dr. Marcel Weber

I am particularly interested in the social-psychological foundations of interpersonal attraction, love, and sexuality. I enjoy using a variety of different methods for data collection (e.g., experience sampling, randomized response technique) and data analysis (e.g., multilevel modeling, SEM, meta-analysis).
