    Ep. 46: Live from Pittcon with Award Winners Bob Pirok and Justin Godinho

    In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with two recent award winners live from the Pittcon conference in San Antonio, Texas: Dr. Bob Pirok and Dr. Justin Godinho. Dr. Bob Pirok is an Associate Professor at the University of Amsterdam in the Netherlands, where he also completed his Ph.D. under the direction of Professor Peter Schoenmakers. He is an expert in multi-dimensional chromatography and the application of machine learning within the field. At Pittcon we celebrated his receipt of the Emerging Leader in Chromatography Award, presented by LCGC International Magazine. Dr. Justin Godinho is a Senior Principal Scientist at GlaxoSmithKline (GSK) in Upper Providence, Pennsylvania. He completed his undergraduate work at Davidson College and his Ph.D. under the direction of Professor Jim Jorgenson at the University of North Carolina at Chapel Hill. Before joining GSK, he worked in the column manufacturing business with Advanced Materials Technology. He is a recognized expert in column technology at both capillary and analytical scales, as well as the analysis of small and biotherapeutic molecules. At this year's conference, he received the Young Investigator in Separation Science Award, sponsored by the ACS Division of Analytical Chemistry. In the conversation, we discuss the recent award sessions for both guests and the evolution of their respective careers. We explore Justin’s transition from fundamental column packing research to biopharmaceutical applications at GSK, touching on the ongoing need for protein-suitable columns, capillary-scale techniques, and the Hydrophobic Subtraction Model column database. We then shift to Bob’s research on automated method development discussed at the meeting. This includes a deep dive into data-driven chromatography, the complexities involved in establishing effective Chromatographic Response Functions (CRFs), and why setting realistic expectations for artificial intelligence and automated method development is critical to avoiding a future "AI winter."

    Ep. 44: Be a Nice Person

    In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Dr. Pierre-Hugues (PH) Stefanuto who is an Associate Professor and Lead Scientist in the Molecular System Research Unit at University of Liège in Liège, Belgium. He previously received both his M.S. and Ph.D. degrees from the same institution. Following his graduate work in Liege he was a postdoctoral research fellow at Dartmouth College. He is a recognized world expert in multidimensional gas chromatography, where he focuses on profiling volatile organic compound mixtures in various life science samples. Currently, he is focused on developing multi-omics screening approaches to tackle biomedical challenges at the molecular level. He has received a number of accolades to date, including the John Phillips Award and Richard Sacks Award, which are two of the highest honors in the field of multidimensional gas chromatography. He is also one of the co-chairs of the ongoing Multidimensional Chromatography Workshop symposium series. In the conversation we talk about PH’s early experiences as a kid scientist, both experimenting in the kitchen at home, and as a laureate of the Chemistry Olympiad in Belgium. We then move on to discuss the Multidimensional Chromatography Workshop - the early days, the alignment with PH’s professional interests, the 17th annual workshop in Williamsburg, VA, and the upcoming 18th workshop in Liège in early 2027. We also talk about the “Century Mix” Project, which was discussed at the Williamsburg with guidance from PH and Dr. John Dimandjia, and has aims to democratize the characterization of GCxGC systems, and provide open datasets for anyone in the community to use. Later in the conversation we briefly discuss two of PH’s recent papers in the GCxGC field, both focused on aspects of data analysis. Finally, we finish with some quick hits, where PH has great advice for young scientists.

    Ep. 42: Did You Look at the Raw Data?

    In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Professor Kelly Hines. Dr. Hines is an associate professor in the Department of Chemistry at the University of Georgia in Athens. She received her B.S. degree in Chemistry from the University of Florida, and then completed the Ph.D. in Chemistry at Vanderbilt University. Her doctoral studies focused on monitoring biomolecular signatures of disease via ion mobility and mass spectrometry techniques, and then she moved on to post-doctoral experiences at two different institutions. The first stop was at the metabolomics resource core at the Mayo Clinic, and the second stop was in the Department of Medicinal Chemistry at the University of Washington School of Pharmacy. Kelly has won several awards in the field of chemical analysis, including recognition as a Female Role Model in Analytical Chemistry by Analytical and Bioanalytical Chemistry, as an Emerging Investigator by the Journal of the American Society for Mass Spectrometry, an ASMS Research Award (which is one of the top honors that young investigators in MS can receive), and very recently was named as the Chemist of the Year by the Northeast Georgia Section of the American Chemical Society. In a wide-ranging conversation, we discuss the early origins of Kelly’s interest in science rooted in her opportunity to explore the plant nursery managed by her father, and then her turn from civil engineering to analytical chemistry inspired by an early undergraduate course “Chemistry for Engineers”. We discuss Hines’ recent and ongoing work involving the use of ion mobility mass spectrometry (IMS-MS), with pre-separation using chromatography when appropriate, for multi-omics studies, aimed at deeper understanding of the biochemistry of organisms at the metabolite level. We also discuss Kelly’s positive experiences developing peer networks through regular attendance at conferences, particularly the American Society for Mass Spectrometry (ASMS) annual meeting, experiences in her second post-doctoral position that inspired her to pursue an academic position, and her approach to mentoring graduate students who show up in her laboratory with diverse backgrounds, interests, and abilities.

    Ep. 40: Curiosity, Collaboration, and Open-Mindnesses are the Keys

    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.

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

    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.
