Devin: What is your superpower?
Nicole: Willingness to take bold leaps and embrace the unknown.
Imagine a world where cancer is as treatable as the flu. That’s the vision Nicole Paulk, the founder and CEO of Siren Biotechnology, is working tirelessly to bring to life. Driven by groundbreaking science, Nicole’s company is on the brink of launching clinical trials for a revolutionary cancer treatment.
Nicole’s work leverages engineered viruses—those that don’t make you sick—to deliver genetic medicines directly to cancer cells. These “good viruses” act as a delivery system for anti-tumor drugs, targeting difficult-to-treat cancers like recurrent high-grade gliomas, a fatal brain cancer. “We started to see data that looked really promising in this space,” Nicole explained, adding, “We felt a moral obligation to go after this cancer where there’s just this huge unmet need.”
Siren Biotechnology’s approach is designed to have broad applications. Unlike treatments that target specific genetic mutations, their method has the potential to work on various tumor types. Nicole describes it as using viruses like a “little FedEx delivery truck” that can be engineered to deliver medicine precisely where it’s needed in the body.
This innovation didn’t happen overnight. Nicole, a former professor of virology at UCSF, took the bold step of leaving academia to launch Siren Biotechnology. “I decided to resign from my faculty position and go be the founder and CEO just because I was so excited about the data and what we had so far,” she shared.
In addition to traditional venture capital funding, Siren Biotechnology is inviting the public to invest through a regulated investment crowdfunding campaign. This unique opportunity allows patients, families, and supporters touched by cancer to be part of their journey. “We wanted to bring patients and their families onto our cap table,” Nicole said. “It’s a way to involve them in the conversation much earlier.”
Siren Biotechnology’s work could redefine cancer care and inspire a new model for patient-centered innovation. With clinical trials just months away, the future looks brighter for those battling cancer—and for all of us who dream of a world where cancer is no longer a death sentence.
tl;dr:
Nicole Paulk’s Siren Biotechnology transforms viruses into targeted cancer therapies with universal potential.
The company focuses on recurrent high-grade gliomas, a fatal brain cancer with no standard treatment.
Nicole left academia to lead Siren, leveraging her groundbreaking virology research to launch the company.
Siren’s unique crowdfunding campaign lets patients and families invest in the fight against cancer.
Nicole’s superpower, fearless innovation, drives her bold mission to revolutionize cancer care.
How to Develop Fearless Innovation As a Superpower
Nicole’s superpower is her willingness to take bold leaps and embrace the unknown. After spending nearly two decades building her academic career, Nicole left her position as a virology professor at UCSF to start Siren Biotechnology. She explained, “I feel like my superpower is just kind of being willing to jump off the cliff without a parachute and be like, we’re going to figure it out. We’re going to make it work.”
Nicole exemplified fearless innovation when her research led to a groundbreaking discovery about the biology of a virus, one that required rewriting existing textbooks. Initially met with skepticism, her work was later validated and became a foundation for Siren Biotechnology’s cancer treatment. This pivotal moment highlights Nicole’s courage to challenge conventional knowledge and pursue transformative ideas.
Tips for Developing This Superpower:
Be willing to question conventional wisdom and explore new paths.
Take calculated risks, even if it means stepping away from a well-defined career path.
Embrace discomfort and uncertainty as a necessary part of innovation.
Engage others by communicating your vision in relatable and accessible ways.
By following Nicole’s example and advice, you can make fearless innovation a skill. With practice and effort, you could make it a superpower that enables you to do more good in the world.
Remember, however, that research into success suggests that building on your own superpowers is more important than creating new ones or overcoming weaknesses. You do you!

CEO, Founder, President, Siren Biotechnology
About Siren Biotechnology: We are combining two transformative therapeutic technologies – AAV gene therapy and cytokine immunotherapy – into a single, reimagined modality that overcomes key challenges and redefines how we destroy tumor cells and elicit anti-tumor immunity.This is the first AAV gene therapy drug product that can be made once and used in numerous indications – a huge leap forward for the field.
This drastically reduces clinical development times, manufacturing timelines, and capital needs for each clinical trial. Most importantly, ‘universal’ means countless solid tumor cancer patients – regardless of tumor type or mutations – may benefit from this breakthrough approach.

With nearly two decades of expertise, Nicole has been at the forefront of developing cutting-edge advances to propel the field of gene therapy forward for a wide range of diseases.
Before founding Siren, Nicole held various leadership positions in academia and industry and most notably was an Assistant Adj Professor of AAV Gene Therapy in the UCSF Department of Biochemistry & Biophysics before leaving to found Siren. Nicole has a B.S. in Medical Microbiology, a Ph.D. in Viral Gene Therapy and Regenerative Medicine from OHSU, and completed her Postdoctoral Fellowship and Instructorship in Human Gene Therapy at Stanford University prior to starting her lab at UCSF. Nicole is a pioneer in the development of next-generation AAV platforms for gene repair, gene transfer and gene editing, directed evolution for novel engineered capsid evolution, and comparative multi-omic approaches to interrogate translational AAV biology.
Nicole is a renowned expert in gene therapy and has consulted extensively for big pharma, written draft CMC guidance for the FDA, and sits on the Scientific Advisory Boards for Sarepta, Astellas, Metagenomi, Dyno Therapeutics, CEVEC, GRO Biosciences, Excision BioTherapeutics, WhiteLab Genomics, Johns Hopkins Gene Therapy Initiative, the Gene Therapy for Rare Disorders Searchlight Program, and several stealth startups. She has been quoted in The Wall Street Journal, The Economist, The Boston Globe, Endpoints, STAT, Phacilitate, GEN, BioPharma Dive, Evaluate Vantage, SF Business Times, WIRED, Drug Discovery World, MIT Tech Review, C&EN, and more. She sits on the Scientific Editorial Boards of the journals Gene Therapy, Human Gene Therapy, and Biopharma International Gene Therapy. She is the Chair of the American Society of Gene and Cell Therapy (ASGCT) Translational Science Committee, and a member of the ASGCT Cancer Cell and Gene Therapy Committee and the Biocom California Cell and Gene Therapy Committee. She has invented numerous AAV gene therapy technologies that have been shared or licensed to dozens of gene therapy companies and nonprofit groups working in rare diseases.
Outside of work, you can find Nicole adventure traveling (think whitewater rafting meets backcountry trekking), snowboarding, planning elaborate Halloween parties complete with animatronics and ghoulish menus, tending her vegetable garden, and obsessing over the latest wearable gadgets. If you’re trying to track her down at a conference and can’t find her, it’s because she snuck off to an oyster bar.
