The 17th Multidimensional Chromatography Workshop

The 17th Multidimensional Chromatography Workshop is a free event involving keynote and contributed presentations, a poster session, and discussion groups on all multidimensional techniques, and will be held in-person on the campus of William & Mary in Williamsburg, VA, January 13–15, 2026. The workshop welcomes both experts and new users to the field for training, networking, and sharing the latest trends. Keynote lecturers will present on major trends in both multidimensional gas chromatography (MDGC) and multidimensional liquid chromatography (MDLC), offering insights from both academia and industry.

Participants will be able to join guided discussions intended to stimulate a dialogue on key areas of the field. The full program will include popular topics, including method development strategies, data analysis, and applications in different industries and research areas. In addition, the program features a poster session, and presenters will have the chance to compete for two poster awards:

• Multidimensional GC Poster Award: Sponsored by the American Chemical Society’s Subdivision on Separations Chemistry and Chromatography—$250 USD Award
• Multidimensional LC Poster Award: Sponsored by the American Chemical Society’s Subdivision on Separations Chemistry and Chromatography—$250 USD Award

Keynote Lectures

This year, the workshop will highlight the work of four keynote speakers. The speakers have experience in either multidimensional GC or multidimensional LC and represent both the academic and industry sectors.

Keynote Speakers

Haleigh Boswell, Chevron

Presentation Title: The GCxGC Effect: Transforming Industries One Molecule at a Time

Haleigh Boswell obtained her Ph.D. in analytical chemistry from the University of Waterloo. She is a research chemist at Chevron with six years of experience in the energy sector. She specializes in comprehensive two-dimensional gas chromatography (GC×GC) with various detectors (flame ionization detection [FID], sulfur chemiluminescence detector [SCD], and time-of-flight mass spectrometry [TOF-MS]), driving technological innovation to enhance laboratory capabilities and providing technical support to refinery and Chevron internal/external partners. Passionate about mentoring, she volunteers with the UC Berkeley Global Access Program, advising students on graduate school and industry careers, and actively participates in outreach events to inspire future scientists. 

Zachary Breitbach, Abbvie

Presentation Title: 2D-LC as a Powerful Technique in the Pharmaceutical Scientist's Toolbox for Small Molecules and Biologics

Zachary Breitbach earned his Ph.D. in analytical chemistry from UT Arlington in 2010 after completing his BS in chemistry at Clarke College. He co-founded AZYP, LLC, focusing on chiral and hydrophilic interaction liquid chromatography (HILIC) separation technologies, before joining AbbVie in 2016 to develop new methods and technologies for drug development. His research has advanced cyclofructan-based chiral and HILIC phases and superficially porous particle-based chiral stationary phases. He has published over 70 articles, holds three patents, serves on several editorial boards, and has received multiple awards, including the ACS Satinder Ahuja Award (2017), LCGC Emerging Leader Award (2018), and the ACS Early Career Investigator Award (2025).

Peilin Yang, Dow Chemical

Presentation Title: Multidimensional Chromatography for Chemical Analysis – From Small Molecules to Synthetic Polymers

Peilin Yang is an R&D fellow at The Dow Chemical Company. She joined Dow in 2007 after earning a Ph.D. in analytical chemistry from the University of Michigan. Currently, she leads multiple research efforts at Dow to advance measurement science and material characterization capabilities aimed at developing safer and sustainable materials. Her recent research focuses on developing practical analytical solutions using multidimensional chromatography (GCxGC and LCxLC), coupled with mass spectrometry and other detectors, to address various industrial challenges, including small-molecule impurities and complex composition analysis of large synthetic polymers. 

Hilal Ezgi Toraman, Penn State University

Presentation Title: Multidimensional Gas Chromatography for Plastic Waste Pyrolysis

Hilal Ezgi Toraman leads an interdisciplinary research program at Penn State focused on sustainable reaction engineering and catalysis for the valorization of non-traditional carbon feedstocks, particularly plastic waste. Her group integrates advanced pyrolysis experimentation, GC×GC-based analytics, and kinetic modeling to develop and optimize scalable chemical recycling technologies. She leads multi-institutional projects on mixed plastic pyrolysis and catalytic upgrading, where her group contributes intrinsic kinetic studies, GC×GC method development, and data management and analysis infrastructure to support process design and evaluation. Toraman has received both national and international recognition, including the C&EN Talented 12, AIChE CRE Pioneers in Catalysis and Reaction Engineering, and ACS Energy & Fuels Rising Star. She has held leadership roles as director of AIChE's Catalysis and Reaction Engineering Division and currently serves as president of the Pittsburgh-Cleveland Catalysis Society. Her honors include the Virginia S. and Philip L. Walker Jr. Faculty Fellowship and the Wilson Fellowship. Before joining the Penn State faculty, Toraman was a postdoctoral researcher with the Department of Chemical and Biomolecular Engineering and Delaware Energy Institute at the University of Delaware. She received her B.S. and M.S. degrees in chemical Engineering from Middle East Technical University, Türkiye (Turkey), and her Ph.D. degree in chemical engineering from Ghent University, Belgium. 

Focus Groups

This year, the workshop will host a guided discussion focused on a topic of contemporary importance in the field of multidimensional chromatography. This will also be an opportunity for individuals to interact more informally to learn more about certain topics or to contribute their expert opinions. Guided discussions will be led by experts in multidimensional separations.

Registration is completely free of charge and can be completed at www.multidimensionalchromatography.com. We hope that you will join us for this exciting event, whether you are looking to find out what multidimensional chromatography is all about, looking to improve your skills, or hoping to improve your network in this exciting field.
