As a statistician, my research involves the comparison of existing and the development of new methods for the analysis of data generated in various fields of research. I am primarily interested in the methodological aspects of systematic reviews and the statistical methods used for meta-analyses, but my interests more generally encompass the design and analysis of longitudinal and multilevel studies using appropriate random-effects and mixed-effects models. If that sounds like a bunch of gobbledygook to you, just remember that data science is the sexiest job of the 21st century – rawr! Probably the most useful contribution of my academic career – at least the one that I think had the most impact – has been the creation of the metafor package, a free and open-source add-on for conducting meta-analyses with the statistical software environment R. A paper published in the Journal of Statistical Software (Viechtbauer, 2010a) describing the package has been cited over 10,000 times (which is likely to reflect only a fraction of its actual use). More information about the package and its ongoing development can be found on the metafor package website. In addition, I have written some more technical papers over the years, comparing and developing statistical methods for analyzing meta-analytic data with random/mixed-effects (meta-regression) models (e.g., Jackson et al., 2014; Lopez-Lopez et al., 2014; Viechtbauer, 2005, 2007a, 2007b, 2007c, 2010b). Along the way, I have also provided help and assistance on a number of applied meta-analyses and primary research projects/studies (including a number of RCTs) pertaining to a wide variety of topics (e.g., personality, cognition, physical therapy, cardiovascular disease, psychopathology, medication adherence, smoking cessation, diabetes management, school violence, childhood abuse, psychotherapy). Here and there, I also may have had something potentially useful to say about other methodological issues and methods (e.g., de Bruin, 2012; Kotz et al., 2012; Viechtbauer, 2007d; 2010c). If you would like to find out more, you could take a look at a list of my publications (citation info on Google Scholar – not like I care about things like that).
