Karla Maria S. Rothstein (born 1966) is an American architect and adjunct Associate Professor at Columbia Graduate School of Architecture, Planning and Preservation, where she is also the founder and director of Columbia University's trans-disciplinary DeathLAB[1] Rothstein is also the co-founder of Latent Productions, an architecture, research, and development firm in New York City, which she co-founded in 1999 with Salvatore Perry.

Rothstein's first built work was "Ballston Lake House" near Saratoga Springs, New York, developed with Joel Towers, which is anchored by 150,000 pounds of precast concrete.

[8] Current projects include the design and development of 25 units of affordable housing in Brownsville, Brooklyn, awarded through the New York City Department of Housing Preservation and Development,[9] the design of environmentally-advanced civic infrastructure to replace urban cemeteries, an environmentally-conscious childcare facility in New York City, a prototype for a resilient small scale building in a Rockaways flood zone, and the conversion of a 240,000 square foot former mill in the Berkshires called Greylock Works,[10] among others.

Greylock Works is little more than two years into a renovation process that will transform the former industrial site converted into a mixture of food production, residential, hotel and restaurant space.

[13] In July 2018, an extensive exhibition entitled DeathLAB: Democratizing Death opened at the 21st Century Museum of Contemporary Art in Kanazawa, Japan and will run until March 2019.
