Ep 35: On the Subject of Continuing Education for Spectroscopists.

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Dr. Alix Rodowa, Research Chemist within the Organic Chemical Metrology Group at the National Institute of Standards & Technology (NIST) in Gaithersburg, Maryland. At NIST, she is the Environmental Sector Task Lead for the Organic Analysis Working Group for the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology (or CCQM).

After discussing some of the events that sparked Dr. Rodowa’s interest in science, and analytical chemistry in particular, we discuss her path to a career as a NIST scientist, including cold-emailing potential research advisors, and an experience as a National Research Council (NRC) postdoctoral fellow. We then discuss her work on polyfluoroalkyl substances (PFAS), including the development of the PFAS Interference List - affectionately known as the “PIL” - and the development of a Standard Reference Material (SRM) for that research area. We also touch on emerging uses of machine learning in workflows for analytical target and suspect screening. Finally, Alix provides some insight into a day in the life of a NIST scientist, why she enjoys working in a government laboratory, and how aspiring scientists can explore this environment as a potential career option.


Ep. 36: A Day in the Life of a NIST Scientist

Here in Episode #37, podcast host Dr. Jerry Workman speaks with Dr. Austin Daniels, application scientist for Yokogawa Fluid Imaging Technologies. This Episode will focus on flow imaging microscopy (FIM), a new technology for subvisible particle characterization in biologics.

We have invited Austin to our Analytically Speaking podcast to discuss the current trends and state of using FIM to ensure the quality and safety of biologics. This requires precise monitoring of subvisible particles, which can impact drug efficacy and patient health. Traditional analysis methods, such as light obscuration (LO) and membrane microscopy (MM), provide limited data on particle types and morphology, making it difficult to pinpoint contamination sources.

Ep 39: Space and Spectroscopy: Two Very Important Things

Dr. Wilson is a research chemist and coordinator of the Cannabis Research Program in the Chemical Sciences Division at the National Institute of Standards & Technology (NIST) in Gaithersburg, Maryland. He received his B.S. degree in Chemistry from Greensboro College followed by a M.S. degree in Chemistry from the same institution. He then moved south to pursue a Ph.D. in Chemistry at the University of Central Florida, training in the lab of Prof. Andres D. Campiglia.

In a wide-ranging conversation, we discuss the influence of 2000’s television shows such as CSI on Brent’s interest in forensic science and analytical chemistry, and how an informal interview at a poster session ultimately led to the position he now holds at NIST. Dr. Wilson shares how he navigated the educational landscapes in forensic science and chemistry, both at the undergraduate and graduate levels. We discuss the evolution of cannabis standards and analytical characterization in recent years, and Brent shares his perspective on the importance of standards in general, the birth of a reference material, and the significant effort it takes to bring these materials to the point where analytical scientists like us can purchase them. Dr. Wilson also describes some of his work on low-temperature emission spectroscopy techniques, where molecule exhibit much narrower and specific emission bands compared to room temperature detection. Brent also shares more about the life of a scientist within NIST, from day-to-day activities, competing for federal funding, and more. Finally, Dr. Wilson shares some professional advice, including the importance of being prepared and adaptable, the value of talking with people at conferences, and the importance of establishing and maintaining relationships over the course of one's career.


Ep. 38: Being prepared isn’t just for Boy Scouts

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Professor Luis Colon. Dr. Colon is is the SUNY Distinguished Professor, A. Conger Goodyear Professor, and Associate Dean for Inclusive Excellence in the College of Arts and Sciences at the University at Buffalo. He received his bachelors degree from University of Puerto Rico at Cayey, and then received the Ph.D. from UMass Lowell. He also was a postdoctoral fellow in the Zare Group at Stanford where did groundbreaking work in detection for capillary electrophoresis. Colon has won numerous awards, including most recently the Kirkland Award in Chromatography (formerly known as the ACS Award in Chromatography), which we celebrated at the ACS Fall 2025 National Meeting. 

In a fascinating conversation, we discuss the influence of Luis’ father on his scientific career, by demonstrating to Luis (whether he realized it at the time or not) a physical separation of coffee shells and beans in the wind. Dr. Colon explains the origins of his interest in materials development for chromatography, which included observations he made on the relatively short lifetimes and fragility of silica-based materials while working in industry early in his career. We also spend a good bit of time discussing Prof. Colon’s motivations for an approach to mentoring younger scientists, as well as some of his thoughts about the future of the separation science field. Finally, Luis shares some of his wisdom gained over several decades as a successful and well recognized analytical scientist, emphasizing the importance of curiosity, collaboration, and open-mindedness.
