Welcome to “Analytically Speaking,” the new podcast from LCGC and Spectroscopy.

Here in Episode 3, podcast host Jerry Workman talks to talks to Prof. Karl Booksh of the Department of Chemistry and Biochemistry at the University of Delaware, Newark, who is an expert in Raman and Raman imaging, LIBS, fluorescence, portable chemical sensors, miniaturization of analytical devices, and data driven science incorporating many chemometrics and data analytics techniques. He discusses a National Science Foundation workshop he is organizing with Prof. Barry Lavine entitled, “Data-Driven Measurements and Instruments for Chemistry.”

We spoke to Prof. Karl Booksh about his organizing an NSF workshop to explore research on the development of portable chemical sensors for environmental, biomedical, and industrial process monitoring. Karl’s own research is predicated on the belief that it is better to build small chemical sensors capable of reliable measurements in the field or in the process than to collect samples for future laboratory analysis.

In this episode, podcast host Dr. Dwight Stoll talks with Dr. Katelynn Perrault, an Associate Professor of Forensic Science and Chemistry at Chaminade university in Honolulu, about her pathway to separation science, her research on the composition of odors from decomposing remains, and her thoughts about what the separation science community can do to get more women involved in the field. Drs. Stoll and Perrault talk about multi-dimensional gas chromatography (GCxGC)— which is Perrault’s primary research tool—ranging from where the technique stands today, to where progress will likely occur in the near future, and why the technique is so well suited to the analysis of decomposition odors.

Welcome to “Analytically Speaking,” the new podcast from LCGC and Spectroscopy.

Here in Episode #1, podcast host Jerry Workman talks to Prof. Barry Lavine of the Department of Chemistry at Oklahoma State University. Prof. Lavine and his research group have been working on new approaches and algorithms for identification and classification of samples measured using infrared (IR) imaging microscopy in forensic analysis. He discusses aspects of sampling, spectra collection, image generation, and data analysis for infrared imaging and sample identification. Data analytics topics include alternate least squares (ALS) reconstruction of the IR spectra of the individual layers from automotive paint samples using machine learning techniques, spectral database searching, and special experimental design methods.

Active research projects in his laboratory touch on most aspects of multidimensional separation methodologies, including optimization strategies, characterization of selectivity in reversed-phase LC, instrument development, and applications in biopharmaceutical analysis. Stoll is the author or co-author of more than 80 peer-reviewed publications and six book chapters and has instructed numerous short courses in 2D-LC. In 2011 he was the recipient of LCGC’s Emerging Leader in Chromatography Award. In 2017 he received the Georges Guiochon Faculty Fellowship, and was recognized with an Agilent Technologies Thought Leader Award. He is also a member of LCGC’s editorial advisory board and is the editor of the “LC Troubleshooting” column in LCGC.

Jerome Workman, Jr., PhD:

Jerome (Jerry) J. Workman, Jr. is the Senior Technical Editor for LCGC and Spectroscopy. He has held positions as CTO, executive VP, senior research fellow, director, and senior scientist at companies of all sizes, from start-ups to world-leading corporations. He has been an adjunct faculty member of four universities and advised multiple graduate students. He has more than 75 U.S. and international patent applications and 30 issued U.S. and international patents and multiple trade secrets, as well as 500+ technical publications, and 20 reference book volumes on a broad range of spectroscopy and data processing techniques. He has received multiple awards from scientific societies, and has taught annual courses in spectroscopy, chemometrics, and statistics for the AOAC, ACS, ISA, FACSS, and at several universities and corporations. He is a Fellow of the American Institute of Chemists (FAIC), the American Society for Testing and Materials (ASTM), and the Royal Society of Chemistry in the UK (FRSC, CChem, CSci). Jerry holds B.A and M.A degrees from Saint Mary's University of Minnesota, and a PhD degree from Columbia Pacific University working in near-infrared spectroscopy. He is an alumnus of both Columbia University Business School and the MIT Sloan School of Management.
