Main professional highlights: Started EPA's Sea Level Rise project in 1982. It's continuing mission has been to accelerate the process by which society addresses the consequences of rising sea level. Main publications include the first assessment of decisions affected by rising sea level, the first national assessment of the possible loss of wet and dry lands, the first probabilistic assessment of how much the sea will rise, the first legal analysis of tools to enable wetlands to migrate inland as the sea rises, and currently in the middle of the first comprehensive assessment of the portion of tidal shores likely to be armored in the coming decades. Has also been one of the co-authors in three reports by the Intergovernmental Panel on Climate Change.

Underlying much of this work is the assumption that under natural conditions, coastal ecosystems could simply migrate inland as the sea rises; but that coastal development is likely to thwart such a landward migration in may areas. An important exception is the Wildlife Refuge system, where undeveloped dry land just above sea level affords an opportunity for wetlands to migrate inland. For areas where preventing all development is impractical, Titus is the primary architect of a land use planning tool called the "rolling easement" which ensures that wetlands are able to migrate inland without otherwise restricting the use of coastal property.
