Lisann A. Carriker, a former science teacher and human resources officer, died May 31 at her home in Jessup. She was 50.

A spokeswoman for the medical examiner’s office in Baltimore said that determination of the cause of death is pending further tests. She had a stroke in December 2011, her husband said.

Mrs. Carriker was an administrative assistant at Baltimore’s Kernan Orthopaedics and Rehabilitation for a year before leaving in 2011. From 2001 to 2004, she worked in human resources at the ASRC Federal Holding Co. in Greenbelt.

Earlier in her career, she was a science teacher at St. Mark’s School in Hyattsville and a quality-assurance technician at the old American Stone-Mix Inc. in Towson.

Lisann Alicia Brancato was born in Huntington, N.Y. She was a 1985 secondary education graduate of Virginia Tech and received a master’s degree in human resource development from Towson University in 1999.

She enjoyed gardening and home-improvement projects.

Survivors include her husband of 24 years, Roger Carriker of Jessup; three brothers; and a sister.
