Biostatistics/Psychometrics consulting, bohemian scientist.

I usually deal with patients-reported outcomes, esp. health-related quality of life, in clinical trials or community-based studies; I am also involved in biostatistical stuff on outpatients recruited in epidemiological or clinical studies on ASD, personality disorders, substance use, or learning disabilities. I am also versed in genetic epidemiology.

Also on linkedin and twitter, but check my website for more information.
