    Professor Carta Earns Distinction of Being Named a Fellow of the International Adsorption Society

    April 27, 2022

    Giorgio Carta, the Lawrence R. Quarles Professor of Chemical Engineering at the University of Virginia, has been appointed a fellow of the International Adsorption Society in recognition of his distinguished research and education in separations technologies.

    The international society brings together industry, academic and government researchers from throughout the world working in the field of adsorption – a process of using solids to remove substances from gaseous or liquid solutions. Adsorption is used in myriad settings, from manufacturing to public utilities to national defense, to make products and industrial processes cleaner, safer and more effective.

    Carta is a widely cited leader in preparative and process chromatography education and research. Chromatography encompasses techniques for separating mixtures of chemical or biological substances into individual components. Carta, the author or co-author of several books, is a recognized expert in purification processes of biomolecules at manufacturing scale for the production of biopharmaceuticals.

    Over his nearly 40 years at UVA, he has mentored many undergraduates and dozens of Ph.D. students, a number of whom have gone on to distinguished careers in biopharmaceuticals. Carta has helped establish UVA chemical engineering as a reliable source of talent for the industry.

    Textbook publisher Wiley has just released the second edition of Protein Chromatography: Process Development and Scale-Up, co-written by UVA Engineering’s Lawrence R. Quarles Professor of Chemical Engineering Giorgio Carta. First published in 2010, the book warranted an update 10 years later.

    Carta, an internationally recognized leader in preparative and process chromatography education and research, wrote the book with biotechnology professor Alois Jungbauer of the University of Natural Resources and Life Sciences in Vienna, Austria. Chromatography encompasses techniques for separating mixtures of chemical or biological substances into individual components.

    The text partially grew out of a two-week short course Carta and Jungbauer developed and taught for many years at their respective universities. The course and the book were designed for engineers, scientists and technical managers, as well as students, seeking a deeper understanding of chromatographic processes and their scale-up, particularly in pharmaceutical manufacturing where achieving purity of drug ingredients is critically important.

    Carta noted that many advances occurred in the field since the first edition came out. The update includes work by several alumni who have trained in his UVA lab over the years, he said.

    Wiley describes the book as “an all-in-one practical guide on how to efficiently use chromatographic separation methods,” noting, “this fully updated and revised new edition offers comprehensive coverage of continuous chromatography and provides readers with many relevant examples from the biopharmaceutical industry.”

    Alan Hunter, a 2002 chemical engineering Ph.D. graduate who studied with Lawrence R. Quarles Professor Giorgio Carta at the University of Virginia, will represent AstraZeneca as the recipient of the 2020 Division of Biochemical Technology of the American Chemical Society (known as ACS BIOT) Industrial Biotechnology Award at the division’s 2020 meeting in Philadelphia. The award honors AstraZeneca’s Lumoxiti process chemistry, manufacturing and controls team, led by Hunter, for its development and scale up of the process used to produce Lumoxiti, an important new biologic cancer drug. Another Carta lab Ph.D. graduate, Timothy Pabst, was also a member of AstraZeneca’s award-winning team.

    As a student and member of Carta’s bioseparations engineering lab, Hunter studied process chromatography and protein mass transport. He has worked in the biopharmaceutical industry for more than 15 years, beginning his career in 2004 at Pfizer in the global biologics group. In 2009, he moved to AstraZeneca, where he is director of the biopharmaceutical development purification process sciences group.

    Hunter stays involved with the department. He gives an annual lecture on regulatory aspects of biopharmaceutical manufacturing in Carta’s CHE4448 Bioseparation Engineering course. In 2019, he was the keynote speaker at the inaugural CHEERS, the Chemical Engineering Research Symposium.

    Carta said Hunter and Pabst collaborate with his lab on research aimed at better understanding and improving biopharmaceutical manufacturing and have published a number of joint papers.

    Lucas Kimerer’s Poster Prize in D.C. Begets Another Win at International Symposium
