About Excyte

Expert Cytometry, or ExCyte, was born out of the desire to make flow cytometry accessible to anyone interested in learning it. Flow Cytometry used to have an almost cultish existence, using battered notebooks to pass down knowledge. The problem was that this information generally never went beyond a particular institution. Learning was dependent on who you knew (or trial and error over the years), which slowed down progress.

We formed ExCyte with the purpose of gathering people who are as passionate about learning successful flow cytometry as we are. Our goal is to make a lifetime of learning flow cytometry available to everyone. Our team has decades of experience teaching and managing flow labs and we collaborate closely with others like us to present a systematic, structured, and enjoyable program.

Tim Bushnell | Expert Cytometry

Tim Bushnell, Ph.D. – In his own words:

I enjoy answering paradigm-shifting questions and trouble-shooting puzzling glitches. I also like finding new ways to enhance old procedures. I’m passionate about my professional relationships and strive to fill them with positive energy.

My other passions include grilling, wine tasting, and real food. My biggest passion is flow cytometry and my personal mission is to make flow cytometry education accessible, relevant, and fun. I’ve had a long history in the field starting all the way back in graduate school. Here are some of my other credentials:

2012, appointed as Director of the URMC Shared Resource Labs.
2011, appointed Assistant Professor of Pediatrics and Hematology.
2008, appointed Research Assistant Professor and Director of the URMC flow cytometry core.
2004, founded the WNYFUG group, served on the board of GLIIFCA, currently serving on the Executive Committee of ISAC since 2008, currently the Secretary and co-chair of the Membership Services committee.
2003 – appointed the Director of the Center for Pediatric Biomedical Research’s Flow Cytometry Facility at the University of Rochester Medical Center.

My first love is flow cytometry, but my second love is improving our core’s facilities and funding situation. I have written several successful Shared Instrumentation Grants, served on NIH study sections related to flow cytometry, and have lectured extensively on core management principles and operation.


Isaiah Hankel, Ph.D. – In his own words:

Flow cytometry is a powerful technology and I’m grateful to have worked with so many leaders in the field, including Tim above. I’ve been doing flow cytometry for almost 10 years, since my first year of graduate school, and have since gone on to work with FlowJo where I helped develop FlowJo Version 10, training over 10,000 professionals in 20 countries around the world on topics ranging from flow cytometry data analysis and statistics to flow cytometry controls and compensation.

After FlowJo, I was brought on board with Bio-Rad Laboratories as a Senior Cell Biology Systems Specialist in Boston, Massachusetts to help launch, develop, and support the S3 Cell Sorter. Most recently, I moved to Germany with Miltenyi Biotec where I managed their entire flow cytometry instrument portfolio and helped direct the marketing and development efforts behind the MACSQuant Tyto, the world’s first mircochip-based flow cytometry cell sorter. I now consult with a variety of flow cytometry companies, including Bio-Rad and FluoroFinder.

I love the business side of flow cytometry, especially marketing and communications. My goal is to utilize leading edge knowledge and processes in these areas to help bring flow cytometry education to as many people as possible, as quickly as possible. Expert Cytometry is a unique scientific company in that it’s founders are open to new training methods and I’m excited to help them improve the field and to educate the individual scientists in the field.
