Steve Kelsey, M.D.
President, Research and Development
Realizing he wasn’t good enough to make a career out of playing rugby or soccer, Steve went to medical school. Training as an academic hematologic oncologist in London and working as a clinician scientist at Barts and The London before joining the pharmaceutical industry in 2000, Steve was always motivated to have science drive the discovery of novel therapies. In London, he ran a clinical practice treating patients with leukemias and lymphomas in a research-focused environment, ran a research laboratory doing both basic and translational research and taught hematology to medical students. After two years of leading the clinical development of Sutent® for Pharmacia/SUGEN, he joined Genentech where he became vice president of hematology/oncology, playing a significant role in the development of key products such as Perjeta®, Kadcyla® and Erivedge® as well as other molecules in the company’s oncology portfolio. He then led the development of imetelstat, a first-in-class telomerase inhibitor, at Geron where he served as head of research and development and chief medical officer. Following his time at Geron, Steve served as president of Onkaido Therapeutics, a Moderna Venture focusing on discovery and development of mRNA therapeutics for cancer. During his 17 years in the biotechnology industry, Steve has worked with small molecules, antibodies, antibody-drug conjugates, DNA oligonucleotides and mRNA platforms and has driven multiple industry and industry-academia collaborations as part of the mission to provide better drugs for patients with cancer. He has a passion for building and leading high-functioning teams doing groundbreaking cancer research.
Steve graduated with bachelor of medicine and bachelor of surgery degrees (MB ChB) and a doctorate of medicine (M.D.) from the University of Birmingham, U.K. He is a fellow of both the Royal College of Physicians (FRCP) of London and the Royal College of Pathologists (FRCPath), U.K. He has over 100 peer-reviewed publications spanning cell biology, drug discovery, drug development and patient care, and is a named inventor on several patents. He now watches more soccer than he plays.
Margaret (Peg) Horn, J.D.
Chief Operating Officer
Peg initially studied pharmacy, but shortly into that five-year educational program decided to advance her education by attending either medical or law school. A lawyer-professor at her pharmacy school tailored an independent legal study course for her, sealing her fate. She completed pharmacy school and then studied law at Villanova Law School. While still in law school, she worked part-time in DuPont’s legal department and subsequently joined the company counseling its pharmaceutical division.
Led by an entrepreneurial spirit and a desire to see more of the country, she moved to San Francisco. Once there, she embarked on a 30-year adventure in biotechnology, working at both large/public companies (Genencor International and Kosan Biosciences) and small, privately held companies (Cogentus and ProLynx). Through years of biotech experience including international strategic transactions, worldwide litigation and multiple public and private financings, Peg’s role evolved from counsel to business and operational leadership positions.
Peg holds a B.S. in pharmacy and a J.D., as well as an executive M.B.A. She is a member of the Pennsylvania and California bars and is a registered patent attorney with the U.S. Patent & Trademark Office. She is a registered pharmacist in Pennsylvania.
Luan M. Wilfong
Chief Human Resources Officer
Luan enjoys working with people and building great teams. She knows it takes excellent leadership, ongoing collaboration and an engaging environment to build a successful organization and culture. Early in her career, with an economics degree fresh in hand, she was offered a position in a private banking training program with a financial services company. Instead, with the desire to learn about growing strong teams within an organization, she requested the operations/human resources program. From the financial services industry, she transitioned into technology, and eventually into biotechnology, joining Gilead Sciences where she oversaw talent acquisition by directly recruiting for the scientific and clinical functions, led the compensation and employee benefits programs, and managed the human resources due diligence and task integration group for an early acquisition target.
Since her work at Gilead Sciences, Luan has run her own full-service human resources consulting firm, working with numerous organizations across biotechnology, public health, non-profit and high technology fields. This work included growing their staff, coaching their leaders on the importance of leadership and communication, and implementing key human resources functions and processes for their unique business cultures. Luan has also held executive human resources roles, most recently with Audience, Inc., where she was vice president of human resources, leading the function from the pre-IPO stage through an IPO.
Luan received her professional coaching certification through New Ventures West and holds an economics degree from Santa Clara University and a master’s degree in business administration from Golden Gate University. Luan continues to read and study the art of building exceptional teams and cultures.
