Childhood & Early Life
Robert Duggan grew up in Oakland, California, as the third of five siblings. His father was an Irish newcomer who became a manufacturing engineer in America; his mother worked as a nurse.He has shared that his family earnings were limited (“about $800 a month… we searched around the house for missing coins, dimes, and nickels”).In high school at St. Francis High School (Mountain View, California), he played quarterback and served as captain of the football squad, saying: “Guys push your body… we are not dropping this game.”Duggan studied at the University of California, Santa Barbara (UCSB) and later at UCLA, focusing on business and economics.His first entrepreneurial interest appeared as a teen mowing lawns, when he noticed that extra care (edges cut neat, walk-through with the owner) brought better results. He notes that the lesson stayed with him.
Career Journey
Early Ventures & Diversification
Long before biotech, Duggan built experience across divergent industries:
- He invested approximately US$100,000 into Sunset Designs, maker of Jiffy Stitchery kits, and helped grow it to about 80% market share before it was sold for about US$15 million in the mid-1980s.
- He co-founded (or helped found) ventures such as Paradise Bakery & Café (a cookie/bakery business) and later a major outdoor-media transition venture in Eastern Europe via Metropolis Media.
- Duggan invested in technology and robotics early: He was Chairman & CEO of Computer Motion (1997-2003), which later merged with Intuitive Surgical.
Biotech Breakthrough: Pharmacyclics
Where Duggan’s career turned into headline-making territory was with Pharmacyclics Inc.. From 2008 to 2015 he served as Chairman, CEO, and largest investor.
Under his leadership, the company developed the cancer drug Ibrutinib (brand name Imbruvica), a breakthrough treatment for B-cell cancers (e.g., chronic lymphocytic leukemia, mantle cell lymphoma).
In May 2015, Pharmacyclics was sold to AbbVie Inc. for approximately US$21 billion in cash and stock.
This deal is widely cited as one of the key events that made Duggan a biotech billionaire.
Post-Pharmacyclics & Current Focus
After that landmark exit, Duggan turned his focus toward new life sciences opportunities:
- Since 2015, he has acted as CEO of Duggan Investments, a venture-capital and public-stock firm focused on “patient-centered innovative solutions for complex age-related illnesses.”
- He became Executive Chairman and later CEO of Summit Therapeutics Inc. (joined board December 2019, CEO April 2020), where he is guiding antibiotic and cancer programs..
- He also worked as Chairman of the Board of Pulse Biosciences Inc. since November 2017, another biotech company concentrating on new technologies.
Major Works & Achievements
- Leading Pharmacyclics to commercialise Imbruvica and to a ~US$21 billion exit.Receiving high honours: e.g., the French Republic’s Légion d’honneur in 2000, and a U.S. Congressional Medal of Merit.
- Significant philanthropy: He is a Trustee at UCSB, and funded chairs in mathematics/sciences/religious studies at UCSB.
- For his leadership in building and scaling companies, he is frequently described as a visionary investor-operator.
Net Worth & Financial Status
Estimating Net Worth for someone like Duggan (with large private holdings and biotech investments) has a degree of uncertainty. One source lists his net worth at ~US$11.92 billion.
Income Sources
- Returns from the sale of Pharmacyclics to AbbVie.
- Equity stakes in Summit Therapeutics, Pulse Biosciences, and other life sciences ventures.
- Early ventures exist in technology/consumer businesses.
Lifestyle
While detailed lifestyle information is limited (as he keeps much private), it is known he is a surfer (which he has spoken about), is involved in philanthropy, and focuses on innovation in health care more than flashy public celebrity.
Personal Life
Duggan was married to Patricia J. “Trish” Hagerty (whom he met at UCSB), and together they have eight children. They later divorced in 2017.
He is known to enjoy surfing both as a youth in California and later in places such as Hawaii, Costa Rica, and Nicaragua.

- Stay operationally involved: He didn’t just invest; he ran companies (CEO of Pharmacyclics) and helped shape strategy and culture.
- Be willing to diversify: His career spans consumer goods, tech, medical devices, and biotech. The common thread is value creation through change.
- Focus on meaningful problems: In biotech, he chose large unmet-need areas (cancer, aging diseases) where success brings both social and financial rewards.
