4th Separations Webinar
Advancements in Analysis of Biomarkers via Gas Chromatography
We’re thrilled to have you join us for this special event, hosted by the MDPI Journal Separations in celebration of our Special Issue, Chromatographic Analysis of Biomarkers.
For over five decades, gas chromatography has played a pivotal role in biomarker discovery, enabling the precise profiling of volatile and semi-volatile compounds. Today’s webinar brings together leading voices from academia and industry to highlight cutting-edge innovations and real-world applications that are shaping the future of public health and personalized medicine.
We hope this event not only honors the journal’s legacy of excellence but also sparks new ideas, collaborations, and breakthroughs that will propel the field forward.
Date: 28 August 2025
Time: 5:00 pm CEST | 11:00 am EDT

Meet Our Speakers
Dr. Waqar Ahmed
School of Biological Sciences, University of Manchester, UK;
A Research Fellow at the University of Manchester in the Respiratory group. Dr. Ahmed's expertise is in the application of metabolomics to clinical breath research. He was recently awarded the Anton Amann award by the International Association for Breath Research and was highlighted as an emerging investigator in the American Thoracic Society’s Blue Journal.
His current research focuses on understanding the significance of microbial and environmental exposures in chronic respiratory disease and how they can be monitored and prevented, aiming towards improving health outcomes.
Dr. David Alonso
LECO Corporation;
David E. Alonso is an applications chemist at LECO Corporation in Saint Joseph, Michigan. He specializes in the use of modern instrumental tools (e.g., NMR, IR, and MS) for the analysis of complex samples. His current work focuses on the utilization of multidimensional chromatography and high-resolution time-of-flight mass spectrometry for the analysis of metabolomics and environmental samples. In addition, he is interested in the analysis of forensic drugs such as synthetic opioids (e.g., fentanyl analogs) and cannabinoids.
Dr. Jonathan Grandy
Sepsolve Analytical Canada;
Jonathan Grandy received his PhD in Analytical Chemistry from the University of Waterloo, focusing on SPME and TF-SPME sample preparation approaches for GC-MS for both environmental and biological samples. Since joining SepSolve analytical, he has served a joint role as a Service Engineer and Application Scientist, focusing not only on ensuring that newly installed TD-GCxGC-ToF instrumentation is functioning correctly but also on assisting other scientists in successfully implementing new methods in their systems. This has allowed him to continue analytical method development for human breath and skin volatilome with others across North America.
Assoc. Prof. Heather Bean
School of Life Sciences, Arizona State University, USA;
Heather Bean is a bioanalytical chemist that specializes in untargeted volatilomics using two-dimensional gas chromatography–time-of-flight mass spectrometry (GC×GC-TOFMS). Her research team characterizes the volatilomes of humans, animals, plants, and environmental microbial consortia with two main purposes: 1) developing novel biomarkers and diagnostics, with an emphasis on breath tests, and 2) investigating the roles of volatile and semi-volatile metabolites in mediating microbe–microbe and host–microbe interactions.
