Madaba (Arabic: مادبا‎, Hebrew: מידבא‎, Meydba), is the capital city of Madaba Governorate of Jordan, which has a population of about 60,000. Madaba is the fifth most populous town in Jordan. It is best known for its Byzantine and Umayyad mosaics, especially a large Byzantine-era mosaic map of The Holy Land. Madaba is located 30 kilometers south-west of the capital Amman.

Madaba has a very long history stretching from the Neolithic period. The town of Madaba was once a Moabite border city, mentioned in the Bible in Numbers 21:30 and Joshua 13:9. Madaba dates from the Middle Bronze Age.

During its rule by the Roman and Byzantine Empires from the 2nd to the 7th centuries, the city formed part of the Provincia Arabia set up by the Roman Emperor Trajan to replace the Nabataean kingdom of Petra. During the rule of the Islamic Umayyad Caliphate, it was part of the southern Jund Filastin.

The first witness of a Christian community in the city, with its own bishop, is found in the Acts of the Council of Chalcedon in 451, wherein Constantine, Metropolitan Archbishop of Bostra (the provincial capital) signed on behalf of Gaiano, "Bishop of the Medabeni."

George Church (August 28, 1954- ) is an American molecular geneticist. He is currently Professor of Genetics at Harvard Medical School, Professor of Health Sciences and Technology at Harvard and MIT, and a core faculty member at the Wyss Institute for Biologically Inspired Engineering at Harvard University.

With Walter Gilbert he developed the first direct genomic sequencing method in 1984 and helped initiate the Human Genome Project in 1984 while he was a Research Scientist at newly formed Biogen Inc. He invented the broadly applied concepts of molecular multiplexing and tags, homologous recombination methods, and DNA array synthesizers. Technology transfer of automated sequencing & software to Genome Therapeutics Corp. resulted in the first commercial genome sequence, (the human pathogen, Helicobacter pylori) in 1994.

He initiated the Personal Genome Project (PGP) in 2005, and, in 2007, he founded the U.S. personal genomics company Knome (with Jorge Conde and Sundar Subramaniam). He does research on synthetic biology and is director of the U.S. Department of Energy Center on Bioenergy at Harvard & MIT and director of the National Institutes of Health (NHGRI) Center of Excellence in Genomic Science at Harvard.
