The document discusses Nelson Tansu, who became the youngest assistant professor at Lehigh University at age 25, but contrasts this claim with other younger professors like Alia Sabur and Erik Demaine. It explores allegations against Tansu regarding self-citation, self-plagiarism, and coercive citation practices in his academic work, attributing these behaviors to career pressure and self-obsession. The document ultimately critiques Tansu's academic record and reputation within the scientific community.

1. Who is Nelson Tansu?
Research by Roy Perera
Independent Institute of Education and Research
Consultant

2. SensationalYoungest Professor
 “After obtaining his doctorate, Nelson got
the offer to be professors from top
universities in the United States. Finally, in
early 2003, when he was aged 25 years, he
became youngest assistant professor of
electrical and computer engineering,
Lehigh University. Lehigh University is a
top university in engineering and physics
in the East Coast, United States.”

27. Self Plagiarism

28. Self Citation
 Tansu publish copiously, duplicating
publication in conferences and journals, and
like to cite himself heavily.
 The reason ofTansu to commit misconduct,
can be explained by Career pressure.
 Scientists depend on a good reputation to
receive ongoing support and funding; and a
good reputation relies largely on the
publication of high-profile scientific papers.
 Clearly, this may motivate desperate (or
fame-hungry) scientists to fabricate results.

30. Self Plagiarism
Surface plasmon dispersion engineering via double-metallic Au/Ag layers

After publishing the same paper 3 times,Tansu made it a patent!

32. Tansu Style
 Tansu publish
copiously, duplicating
publication in
conferences and
journals, and like to
cite himself heavily.

33. Coercive Citation
 A journal’s editor is uniquely positioned
to be familiar with the papers published in
his journal and may highlight his own
references that is of at least relevance to
the one chosen by the author, as part of
normal peer-review.This is coercive
citation.

39. Milena Penkowa?
 Milena Penkowa was a Danish
neuroscientist, is another case that
has made a big news in the research
community.Milena Penkowa
represents an interesting case of a
young scientist making a fantastic
career in Danish science at
Copenhagen University.At every
possible occasion Milena Penkowa
was put forward as a role model for
young scientists. Now, to the
embarrassment of the Danish
scientific establishment, it turns out
that Milena Penkowa was cheating
with her scientific works
