Justin Zelin, a widely respected Director and Senior Biotechnology Analyst based in Miami, Florida, has died, leaving a significant void in the biotechnology investment community.

Zelin was known for his incisive analysis and deep understanding of emerging scientific trends that shaped the rapidly evolving field of biopharmaceutical research and development.

At BTIG, where he served as Director and Senior Biotechnology Analyst, Zelin became a trusted voice for institutional investors navigating some of the most complex and high‑growth areas of medicine.

His coverage spanned breakthrough sectors including cell therapy, targeted oncology, and immunology, areas that promise profound impacts on the treatment of cancer, autoimmune disorders, and other serious diseases.

Colleagues and clients alike valued his ability to interpret scientific advances and translate them into insights that informed investment decisions.

Before joining BTIG’s healthcare research team, Zelin built a formidable professional foundation. Early in his career, he held analytical roles with leading firms such as Canaccord Genuity, SVB Leerink, and B. Riley Securities.

This progression through respected research desks honed his analytical rigor and strengthened his reputation for thorough, evidence‑based judgment.(

Zelin’s engagement with the biotech sector was rooted in more than finance: it drew on a deep academic pedigree.

He earned both a bachelor’s degree in biology and a master’s degree in biotechnology from Harvard University, where he also taught for more than five years.

His time in academia and in laboratory settings gave him unique perspectives that bridged scientific research and financial markets, allowing him to evaluate companies not just by their commercial prospects, but by the robustness of their underlying science.

Throughout his career, Zelin was known for his conviction and willingness to take bold stances when warranted by data.

He frequently maintained strong buy ratings and ambitious price targets on companies he believed were positioned for long‑term success, even amid the sector’s inherent volatility.

His work helped guide capital toward promising innovations and provided investors with confidence in a field driven by both hope and uncertainty.

Beyond his analytical achievements, those who knew Zelin remember him as a thoughtful and engaged colleague who inspired those around him.

His ability to mentor junior analysts and to contribute meaningfully to discussions about scientific and investment strategy made him a valued member of his professional community. The impact of his work extended beyond spreadsheets and reports, it shaped conversations about where the future of medicine might head next.
