But it was a rudimentary machine - a tower in a campus laboratory - which erased that everyone imagined to be a bright future for Ms. Dufault, who also found time to mentor girls interested in science and play saxophone in Yale precision marching band.
On Tuesday, only a few weeks of his degree, upsetting it late at night in a machine shop in a chemistry laboratory, as it had for weeks while working on his thesis: investigation into the possible use of liquid helium to detect dark matter particles. Ms. Dufault, 22, was killed when her hair became caught in the Tower, which Rotary axis is used to contain materials such as wood or metal shaped.
Student members and staff were overwhelmed by the press on Wednesday and met in small groups to share their grief. Linda Koch Lorimer, a Vice-President of Yale and his Secretary, called the death "terrible accident" in a letter to students, and said counsellors were available. A candlelit vigil took place Wednesday evening in the Court of College of Saybrook, the apartment complex where Ms. Dufault lived on the campus of New Haven.
"It was incredibly passionate about all kinds of science, said Joe O'Rourke, a colleague of astronomy and physics major and member of the team of physics." She was the person most difficult work that I don't know. ?
Connecticut chief medical examiner ruled the death an accident, citing the cause as asphyxia due to compression of the neck. The federal Occupational Safety and Health Administration said that it would investigate this point. Ted Fitzgerald, a spokesman for the OSHA in Boston, said that the Office had jurisdiction over the laboratory because Yale employees also use his equipment.
President of Yale, Richard c. Levin, said in a statement that the University would also examine "security policies and practices of laboratories, machine shops and other facilities with power equipment" operated by undergraduate students, science and arts building. Until the review is complete, he said, students will have access to these places only during the hours of play, and monitors will be present.
Mr. o ' Rourke, atelier d'usinage Sterling Chemistry Laboratory, he uses also stated, has always been a member of the personnel present during the hours of the day. But many students use the shop during the night; Dr. Levin has stated that the other students who worked in the building are the body of Ms. Dufault and called the police.
Website of the Department of chemistry, access to the machine shop is "strictly limited" to those who have completed a course of introduction shop. Yale lists security measures online for another workshop of machining on campus, students of warning: "" If you have long hair or a long beard, tie - if your hair are spinning machines, it will be removed if you are lucky.""
Ms. Dufault took an advanced course on the protocols of the machine shop this semester, said Mr. O'Rourke. And for the experience of the NASA reduced gravity, she helped to prepare a paper 60 pages on backups.
"It has always been very careful," he said. "This is why I was shocked that this happened." I've worked with her in this laboratory and has always considered its taking safety precautions. ?
Manfred Philipp, Professor of chemistry at the Lehman College in Queens, which had no direct knowledge, the accident of Yale said towers and similar equipment are notoriously dangerous.
"It really pay attention on a machine like that because he has immense power", he said. "The Tower a renewable of moving parts, and if your hair is stuck in that, then your head would have reached to the machine."
Ms. Dufault, who grew up in Scituate, mass., had planned to pursue an advanced degree in sciences of the ocean. Noble and Greenough to nearby Dedham school, she was known as "one of the earliest students including his never encountered teachers."
"Her spirit, her sense of curiosity, his insight, his sensitivity and his enjoyment of what it was were extraordinary, said Robert P. Henderson Jr., the head of the school." She was a true intellectual. ?
