She is a member of the International Statistical Institute.^[1]

Research

Laird received her PhD from Harvard University in 1975 under Arthur Dempster.

Laird is well-known for many seminal papers in biostatistics applications and methods, including the Expectation-maximization algorithm. She is a highly cited author according to the ISI Web of Knowledge.

Honors

Her honors include the Purdue University Myra Samuels Lecturer award (2004), the Janet Norwood (2003) and F.N. David Award (2001) from the American Statistical Association, and several other fellowships.

(The authors collected a variety of maximum likelihood problems and methods of solving these problems that occurred in the literature. They found that all of these methods had some ideas in common and they named it the EM Algorithm, standing for "Expectation, Maximization".)
