Wahab has interests and expertise in chiral separations, improving the green-ness of chromatographic separations, new detectors for chromatography such as microwave rotational spectroscopy, and new techniques for signal processing in chromatography, among other areas. He and several coauthors recently published a paper in Analytical Chemistry discussing their experiences using generative artificial intelligence (i.e. chatGPT) as a research assistant when working on tasks in measurement science ranging from extraction of rotational microwave spectra from free induction decay signals, to baseline removal from chromatographic data. In the conversation we talk about the origins of this study, strengths and weaknesses of chatGPT as a research assistant in the analytical chemistry space, and the role of generative AI in chemistry teaching and learning. We also touch on tips and tricks also published by Wahab and coworkers for dealing with equations and symbol-heavy text when using generative AI tools. One very interesting application of these tricks is in the translation of relatively old (decades) papers that were published before English became the standard language for much of science publication.

Here in Episode #29, podcast host Dr. Jerry Workman speaks with Dr. Thomas Mayerhöfer from the Leibniz Institute of Photonic Technology in Jena, Germany, about quantitative spectroscopy and wave optics in infrared spectroscopy, including the theory, simulation, and modeling aspects.

In this episode, podcast co-hosts Dr. Dwight Stoll and Dr. James Grinias talk with Dr. Molly Atkinson, Assistant Professor of Chemistry at the University of North Texas in Denton, TX, and her graduate student David Hamilton. Atkinson and Hamilton are experts in Chemistry Education Research (CER), and they recently published a paper discussing results of a survey of bachelors-level chemists working in industry that asked them “What does industry want new chemists to know?”. The paper, published earlier this year in the Journal of Chemical Education, generated quite a lot of buzz on analytical chemistry social media. In the conversation we talk about highlights from the article, and touch on potential future work that could fill in knowledge gaps identified by the first survey. The survey revealed some trends that will be familiar to readers of LCGC Magazine. For example, the surveyed chemists indicated that liquid and gas chromatography are two of the top five most important instrumental techniques that new chemists entering industry should know how to use. On the other hand, the survey also revealed some surprising results - for example, nuclear magnetic resonance (NMR) spectroscopy was not in the top-five instrumental techniques, despite that NMR occupies a prominent position in most undergraduate chemistry curricula in the United States. Finally, the guests and co-hosts discuss a bit about how Chemistry Education Research “works”, for listeners who are less familiar with this discipline than other more traditional research areas.
