During the previous years Rakić has been devoted to bioethics, developing the concept of voluntary moral bioenhancement, a recent field of interest of scientists dealing with human enhancement.

[4] During 2014 Rakić, Robert Sparrow and Harris Wiseman polemicized in the American Journal of Bioethics on the same problem, as well as on other issues related to enhancement.

They include Peter Singer, John Harris, Don Marquis, Nicholas Agar, Ingmar Persson, James J. Hughes and Stefan Lorenz Sorgner.

In May 2013 CSB attracted widespread attention by organizing a conference in Belgrade at which John Harris and Julian Savulescu confronted their differing positions on human enhancement and freedom.

This event gathered an international group of ethics experts in order to discuss genome editing in humans and other living beings.

Before his commitments in the United Nations and the Government of Serbia, Rakić was a senior research fellow at the Center for Higher Education Policy Studies (CHEPS) of Twente University in the Netherlands.

From the beginning of 2020, he criticized the President and Government of Serbia for adopting autocratic policies under the pretext of anti-COVID-19 measures, for counterfeiting data about the number of deceased COVID-19 patients, and for organizing undemocratic and unfair elections that were boycotted by the opposition.

This smear campaign came abruptly to an end as dozens of the world's most famous philosophers, ethicists and scientists (including Peter Singer, Arthur Caplan, John Harris, and Julian Savulescu) signed a letter of support for Vojin Rakić that they sent to the political leaders in the United States and in the European Union and in which they asked them to nudge Vučić into stopping his smear campaign and to publicly apologize to Rakić.
