Charles AuerbachPhD, LCSW

Dr. Auerbach received his BA in sociology/psychology from Brooklyn College in 1976, his MSW from Adelphi University School of Social Work in 1979, and completed his doctoral studies at Fordham University in 1984.  He is a full professor at Yeshiva University’s Wurzweiler School of Social Work (employed since 1988), and was a Visiting Professor at Einstein College of Medicine from 2005-2007.  In addition to his academic work, most recently Dr. Auerbach has been a research consultant for Long Island Jewish Medical Center (since 1999), where he has developed and continues to maintain a patient information system, has developed risk assessment protocols, and conducts program evaluations.  Dr. Auerbach has also been a Research Scholar at The University at Albany’s Research Foundation since 2001.

Dr. Auerbach has been the lead evaluator for two U.S. Children’s Bureau-funded longitudinal studies on recruitment and retention of child welfare workers for the past nine years through the New York State Social Work Education. As a result of this research, Dr. Auerbach has become a leading authority in workforce issues in child welfare, cross-site evaluations, examining system change over time, and research methodology. His publications in this area are often cited. Additionally, he has conducted a number of evaluations for the Administration for Children Services (ACS), New York City's public child welfare system, which have involved both quantitative and qualitative research designs, including the conducting of focus groups.

As a statistician, Dr. Auerbach has developed statistical software, SINGWIN (Auerbach, Schnall, & Heft-LaPorte, 2009), specifically for the evaluation of professional social work practice. The software has been published with a text entitled Evaluating Practice: Guidelines for the Accountable Professional (Bloom, Fischer, & Orme, 2009) and is used in schools of social work and in direct social work practice throughout the country.   

Dr. Auerbach is the first author of SSD for R, an R package for analyzing single-subject research data.  He is also the first author of the upcoming 
text, SSD for R:  An R Package for Analyzing Single-Subject Data.  Along with his co-author, Dr. Wendy Zeitlin, Dr. Auerbach has given presentations on SSD for R and single-subject research methodology at national conferences.
