Dr. Wallace influences students across the country through his textbook on intermediate Greek grammar. It has become the standard textbook in the English-speaking world on that subject. He is a member of the Society of New Testament Studies, the Institute for Biblical Research, the Society of Biblical Literature, and the Evangelical Theological Society. Dr. Wallace is also the senior New Testament editor of the NET Bible and coeditor of the NET-Nestle Greek-English diglot. He has been a consultant on four different Bible translations. Recently his scholarship has begun to focus on John, Mark, and nascent Christology. He works extensively in textual criticism, and has founded The Center for the Study of New Testament Manuscripts (csntm.org), an institute with an initial purpose of preserving Scripture by taking digital photographs of all known Greek New Testament manuscripts. He has traveled the world in search of biblical manuscripts. His postdoctoral work includes work on Greek grammar at Tyndale House in Cambridge, textual criticism studies at the Institut für neutestamentliche Textforschung in Münster, and the Universität Tübingen, Germany. He is in demand as a speaker at churches, colleges, and conferences. Dr. Wallace and his wife, Pati, have four adult sons, three daughters-in-law, one granddaughter, a Beagle, a Labrador Retriever, and a cat. They enjoy all their children and the dogs.
