Who is Boris Nikolic in the Epstein files?

Boris Nikolic is a Croatian-American immunologist, Harvard Medical School-trained physician, and biotech venture capitalist who served as the chief science and technology advisor to Bill Gates from 2000 to 2015. He appears in the Epstein documents as a frequent personal correspondent of Epstein's, exchanging emails over a five-year period from 2012 to 2017. He was also named as the successor executor of Epstein's estate in a will signed just two days before Epstein's death, though Nikolic stated he was 'shocked' by the designation and declined to serve. He later co-founded Biomatics Capital, a healthcare venture firm.

Why was Boris Nikolic named in Epstein's will?

Epstein named Nikolic as the 'successor executor' of his estate in a will signed on August 8, 2019 — just two days before his death. This meant Nikolic would manage the estate if the primary executors, Darren Indyke and Richard Kahn, could not serve. Nikolic publicly stated he was 'shocked' to learn of his inclusion, said he was never consulted, and had 'no intent to fulfill these duties, whatsoever.' The naming suggests Epstein considered Nikolic a trusted associate, though Nikolic has said they had no business ties and that Epstein did not invest in his funds. Both men were clients of JPMorgan Chase's private bank.

What do the emails between Boris Nikolic and Epstein show?

The released emails show a sustained personal relationship between Nikolic and Epstein from 2012 through at least 2017. Topics include forwarding news articles (such as a World Bank nomination in 2012 and a piece about Steve Ballmer in 2013), coordinating weekend plans and travel schedules (including references to trips to Greece), discussing interior decorating details like gold leafing, and exchanging information about mutual acquaintances. The tone is casual and familiar, suggesting a genuine friendship rather than a purely professional association. In one 2017 email, Epstein writes to Nikolic about a woman who 'had little money' and 'couldn't afford air conditioning,' though the full context is unclear from the available excerpts.

Wikipedia

Boris Nikolic, a Harvard-trained immunologist and former chief science and technology advisor to Bill Gates, maintained a sustained personal correspondence with Jeffrey Epstein spanning at least 2012 to 2017, and was named as successor executor in Epstein's will two days before his death.

Nikolic appears extensively in personal email correspondence directly with Epstein, exchanging messages about news articles, travel plans, social introductions, and personal matters over a five-year period (2012–2017). He also appears on a list of high-profile attendees for what appears to be an Epstein-organized seminar or dinner alongside names like Bill Gates, Jeff Bezos, Sergey Brin, Larry Page, Eric Schmidt, Peter Thiel, and Jim Simons. Additionally, recently released documents include draft emails written by Epstein from Nikolic's perspective, including a draft resignation letter and drafts making claims about Bill Gates — though these are not authenticated as Nikolic's own statements. The email exchanges reveal a warm, familiar tone, with casual references to travel schedules, meeting up on weekends, and personal topics.

Key Highlights

•Named as successor executor in Epstein's will signed just two days before Epstein's death in August 2019 — Nikolic said he was 'shocked' and had no intent to fulfill the role
•Personal email correspondence with Epstein spans at least five years (2012–2017), with casual exchanges about travel plans, weekend meetups, and social matters indicating a close personal relationship
•Appears on an elite guest list alongside Jeff Bezos, Bill Gates, Sergey Brin, Larry Page, Eric Schmidt, Peter Thiel, Michael Milken, and Jim Simons for what appears to be an Epstein-organized event
•Facilitated social introductions through Epstein's network, including connections involving members of the Musk family
•Recently released DOJ documents include draft emails written by Epstein from Nikolic's perspective, including a draft resignation letter and claims about Bill Gates — these remain unverified and Nikolic has not been accused of wrongdoing
