Purdue, Citing Research Misconduct, Punishes Scientist
By KENNETH CHANG
An appeals committee at Purdue University has upheld findings of
misconduct on the part of a professor who claims to have created
energy-generating fusion in a tabletop experiment, the university
announced on Wednesday.
With the findings, William R. Woodson, the university's provost, has
imposed punishment on the professor, Rusi P. Taleyarkhan. Dr.
Taleyarkhan remains on the Purdue faculty, but his distinction as a
"named professor" has been removed, along with an annual allotment of
$25,000 that accompanied it.
In addition, he is prohibited from serving as a thesis adviser to
graduate students for at least the next three years.
John Lewis, a lawyer for him, said Dr. Taleyarkhan was considering his
options, among them challenging the sanctions in court.
Beginning with a paper published in the journal Science in 2002, Dr.
Taleyarkhan, who then worked at Oak Ridge National Laboratory, has
claimed that the force of sound waves can collapse bubbles in a liquid
violently enough to generate conditions that fuse together hydrogen
atoms, releasing energy. Scientists working in other laboratories have
not been able to reproduce the experiments.
In July, an investigatory committee at Purdue, though coming to no
conclusions about that finding itself, determined that Dr. Taleyarkhan
had later falsely claimed independent confirmation of the work.
Actually, the committee said, he had been involved in supervising the
follow-up experiment, which was conducted by a postdoctoral researcher
in his laboratory, and in writing the resulting scientific papers.
The committee also found that a graduate student in his laboratory whom
Dr. Taleyarkhan added as an author to those follow-up papers had made no
Dr. Taleyarkhan appealed the decision. The rejection of that appeal, by
a three-member panel appointed by Dr. Woodson, the provost, was unanimous.
Responding to a request for comment, Dr. Taleyarkhan referred in an
e-mail message to the investigatory committee's dismissal of 10 other
accusations of misconduct, including improper presentation of data.
"The immense three-year-long investigation," he wrote, "has thrown out
all allegations related to fraud and fabrication and therefore
represents a success for the science."
