Short Biography

Andrea Prestwich

Andrea Prestwich was born in Bristol, England in 1962 and has been interested in astronomy since she was about 5 years old. In 1984 she graduated from Queen Mary College, London, with a degree in physics. She completed her PhD in Astrophysics at Imperial College London in 1989, then accepted a post-doctoral position as a NRC Resident Research Associate at NASA-Marshall Space Flight Center. In 1991 she moved to the Smithsonian Astrophysical Observatory where she is a Staff Scientist at the Chandra X-ray Observatory. Andrea lives in Massachusetts with husband Steve Saar (also an astronomer) and twins Christopher and Katie.

Andrea's PhD thesis (with advisor Bob Joseph) was titled "Extra-galactic Infra Red Spectrocopy" and included some of the first measurements of near infrared line emission from external galaxies. Later as a postdoc at NASA-MSFC she worked on low mass star formation in cluster cooling flows.

Since the launch of Chandra, Andrea's research has focussed on understanding X-ray souces in starburst and star forming galaxies. She has worked on X-ray source classification, understanding the relation between X-ray emission and star formation activity and Ultra-Luminous X-ray sources (ULXs). In Chandra Cycle 2 (2000) she was PI on a Large Project to study the discrete X-ray source population in spiral galaxies. More recently, she has been working on a variety of Chandra and Hubble projects to study the effects of metallicty on the formation of X-ray binaries, including a Cycle 11 Large Chandra Project to study Ultra-Luminous X-ray Sources (ULX) in extremely metal poor galaxies. She is also involved in studies investigating the links between High Mass X-ray Binary formation and star clusters (with collaborators Rupali Chandar and Blagoy Rangelov) and the connection between ULX and Lyman Alpha emission in blue compact dwarf galaxies.

Chandra X-ray Center (CXC) Activities

Andrea works in the Director's Office at the Chandra X-ray Center. From 2010 to 2014 she was coordinator of the NASA-Einstein Postdoctoral Fellowship Program and is currently responsible for organizing the Chandra Peer Review.
