In this episode, Peter is joined by Joanne and Ray Lannigan, two much-loved figures in the flow cytometry community.

Joanne and Ray share how they found their way into flow from very different beginnings, from Joanne’s early dream of becoming a doctor to Ray’s route through electronics, the Navy, and field service engineering.

They also reflect on the risks, setbacks, and turning points that shaped their careers, including a difficult move to Maryland, financial uncertainty, and the opportunities that eventually led to UVA and Cytek.

Along the way, they discuss mentorship, community, life after retirement, working across time zones, conference adventures, family, food, music, and their ongoing work with ISAC’s Instruments for Science initiative.

In this episode, Peter sits down with Ulf Landegren, Professor of Molecular Medicine at Uppsala University and a pioneer in DNA-based detection technologies.

Ulf shares the story behind one of his lab’s most important breakthroughs, rolling circle amplification, and how it almost didn’t happen when a student pushed ahead despite his doubts.

He also explores how this technology has evolved into powerful methods for detecting cancer mutations with extraordinary sensitivity, offering new ways to monitor disease and patient outcomes, particularly in leukemia.

Along the way, Ulf reflects on the human side of science—from the role of curiosity and persistence in discovery to lively (and very vocal) scientific debates with his son on family bike rides.

In this episode, Peter O'Toole is joined by Virginia Litwin, the President-Elect of the International Society For Advancement of Cytometry (ISAC).

They discuss Virginia's journey from academia to industry and her pivotal role in the creation and development of CYTO Women, a committee that's having a genuine positive impact on the opportunities available for women in cytometry.

She also shares her experiences in translational science, working closely with clinical trials, and her passion for standardization in flow cytometry.
