Two companies founded by genomics pioneer J. Craig Venter are expanding their real estate footprint in La Jolla, leasing additional space from BioMed Realty Trust Inc.

Synthetic Genomics Inc., which develops algae-based biofuels and other such products, will lease about 69,700 square feet of a University Towne Centre building. Human Longevity Inc., launched just last month to create a database that documents the science around the human aging process, will lease the remaining 55,600 square feet of the building. Further, HLI will continue to lease approximately 22,200 square feet at The Research Park at Torrey Pines.

The J. Craig Venter Institute (JCVI) also leases approximately 122,600 square feet at the company’s 9704 Medical Center Drive property in Rockville, Maryland. Companies affiliated with Venter lease more than 270,000 square feet from BioMed Realty across the U.S.

“We are very pleased to be extending our relationship with BioMed Realty and to expand into two properties which offer modern, flexible, amenity-rich facilities in the heart of the San Diego life science community,” Venter said in a statement.
