Two weeks after announcing the resignation of its president, Alexandria Real Estate Equities has named his replacements.

The life sciences REIT promoted Daniel Ryan and Hunter Kass to serve as co-presidents and regional directors of the San Diego and Boston markets, respectively, according to a filing with the Securities and Exchange Commission. Both positions are effective Sept. 15.

Ryan will work in Alexandria's San Diego market overseeing development, redevelopment, joint ventures, financing, leasing and other opportunities. He has worked for Alexandria for 13 years, serving as co-chief investment officer since May 2018 and previously as executive vice president of San Diego and strategic operations from 2010 to 2012.

Kass will be responsible for the company's Greater Boston portfolio and will oversee development, acquisitions and transactions. Kass has worked in the Greater Boston market since 2018, taking on the role of senior vice president in October 2019. Prior to his roles at Alexandria, he was the associate director of MIT Investment Management Co. from 2016 to 2018.

The REIT owns 13.3M SF in Greater Boston and 8.1M SF in San Diego, according to its website. It shrunk its portfolio in June with the sales of several Boston-area properties.

The securities filing also said Peter Moglia, who has served as CEO and co-chief investment officer with Ryan, will now be responsible for being the sole chief investment officer. His title change will also be effective Sept. 15.

The firm Aug. 17 announced its president and chief financial officer, Dean Shigenaga, submitted his resignation citing "personal family health reasons." Marc Binda will fill the roles of chief financial officer and treasurer. Shigenaga will stay with Alexandria in a strategic consulting role, and a new president will be elected before Sept. 15.
