Daniel B. Wallace is Senior Professor of New Testament Studies at Dallas Theological Seminary (has taught there for more than 28 years) and Executive Director of the Center for the Study of New Testament Manuscripts.

As an internationally known Greek New Testament scholar, Wallace has been a consultant for four Bible translations—ESV, TNIV, New King James Bible, and New English Translation. He has also contributed articles to the ESV Study Bible and the Holman Christian Standard Study Bible.Wallace is a frequent speaker at universities, seminaries, churches, colleges, and apologetics conferences. He has given the Staley lectureship (2001), the inaugural and a later Lamplighters lecture (2004, 2007), Annual Conference Lectureship for the Northwest London Diocese of Anglican Priests, London (2009), and has been a frequent speaker at various apologetics conferences.

At New Orleans Baptist Seminary in 2008, at the fourth annual Greer-Heard Point-Counterpoint Forum, he debated Bart D. Ehrman on the reliability of the New Testament manuscripts as witnesses to the original text (the debate later came out as a book by Fortress Press). Bart and Dan debated again at Southern Methodist University on Oct 1, 2011 before the largest crowd ever assembled (1425 people) to witness a debate on textual criticism. A third debate, on Feb 1, 2012, was held at North Carolina Chapel Hill, where Ehrman is a professor.

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, 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, three granddaughters, and a Labrador Retriever. Dan is a fourth-generation Californian, who grew up in Newport Beach. He has been transplanted against his will to Texas. He always welcomes an opportunity to come home. Dan and his wife, Pati, have been married 40 years.
