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

Sensational Youngest 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.”

The Real Youngest Professor

In 2001, at the age of 20, Erik Demaine joined the faculty of MIT, as a professor of computer science. He was the youngest professor ever hired by the university. In 2003, he won a MacArthur genius grant.

Named “one of the most brilliant scientists in America” in 2003 by Popular Science magazine

Youngest Doctor Indian-American ophthalmologist

and academic Balamurali Ambati was doing calculus when he was four years old and co-authored a research book on AIDS when he was 11. At 13, he completed his studies at New York University. And in 1995, when he was 17, he graduated from Mount Sinai School of Medicine, New York City, effectively becoming the world’s youngest doctor (and a Guinness World Record holder).

World Record in Self Citation by Youngest Professor

Self Citation. How does it work?

Tansu

Why Self Citation?

Career pressure: To boost Nelson citation & volume

Why Self Citation?

Self obsession, psychological problem of

people having no security, a form of self

centeredness, a way of expressing his

own ego, self indulgence, self craving.

Self Citation at SPIE

Self Citation at SPIE In 2010, Tansu presented 6 papers at SPIE Conference:

Self citations

Professor Tansu

Self Plagiarism

Self Citation Tansu publish copiously, duplicating

publication in conferences and journals, and like to cite himself heavily.

The reason of Tansu 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.

Self Plagiarism Surface plasmon dispersion engineering via double-metallic Au/Ag layers for nitride light-emitting diodes. After publishing the same paper 3 times, Tansu made it a patent! Self plagiarisms for a patent!

Self Plagiarims

Tansu Style

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

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.

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
