Meet our Staff
Glenn Kawasaki, PhD, MBA, JD
Chief Executive Officer and President
Dr. Kawasaki is a Seattle entrepreneur with 35 years in the biotech industry. He was the first scientist at ZymoGenetics as a Ph.D. geneticist, and was also a research fellow at Harvard Medical School. Dr. Kawasaki is the inventor of ribosome display and founded Aptein, Inc. for cell-free engineering of proteins and peptides. He is founder and president of Catch Inc., developing diagnostics tests for homocysteine, as well as founder and director of Sound Pharmaceuticals, a hearing loss company with a drug candidate in clinical trials. In 2005, he joined Accium BioSciences and helped progress its new business unit, DirectAMS, in 2011. He has served as CEO and President since 2013.
Director of AMS Operations
Jonathan is a new addition to the team, joining us from Wisconsin. Four years of experience working for an industry leader in accelerator technology has granted him intimate knowledge in the maintenance and troubleshooting of accelerator systems, as well as training others in AMS techniques.
As a fresh Seattle transplant he is eager to begin life in the Pacific Northwest. Born and raised in Milwaukee and further shaped in Madison, he obtained his B.S. in Physics and Astronomy-Physics from the University of Wisconsin, Madison in 2013. When he is not tinkering with accelerators, he is probably off riding his bike in the mountains.
James C. Chatters, Ph.D.
Dr. James Chatters is a recognized expert in the human and environmental prehistory of western North America. A broad-spectrum paleoscientist, he has over 45 years of research experience in archaeology, palynology, and paleontology. His intimate understanding of radiocarbon sample selection, treatment, and interpretation is integral to the services provided by DirectAMS.
Dr. Chatters received his Ph.D in Anthropology from the University of Washington in 1982. His work has been published in Science, American Antiquity, Quaternary Research, World Archaeology, Journal of World Prehistory, Journal of Archaeological Science, Canadian Journal of Archaeology, and elsewhere. His current research focuses on Pleistocene mammals, and the bioarchaeology of America’s first peoples, including recent discoveries in the Northwestern US and Mexico. He is best known for his work on Kennewick Man.
Brittany Hundman, MA
Director of Archaeological Services
As the new leader of the Archaeology department, Brittany brings her experience in international field work, museum curations, and isotopic bone chemistry. She hails originally from Virgina but has worked and led teams in many areas, including Peru. She is primarily hands on with sample triage, bone preparation techniques, and customer consultation on sampling strategies. As an ardent advocate of education of archaeological science, you can find her at many of the industry conferences.
Alyssa M. (Puffer) Tate, MS
Director of Laboratory Operations
Alyssa Tate supervises all laboratory operations at DirectAMS. She is responsible for sample receipt and processing, as well as purchasing, equipment maintenance and measurement logistics. Alyssa has graphitized thousands of samples, since entering the field of accelerator mass spectrometry in 2011. She also assisted in establishing the DirectAMS labs, and serves as the resident “carbonate processing” expert. Alyssa stays mobile, splitting her time between the processing laboratory in Bothell and the AMS laboratory in Seattle.
Hailing originally from Nebraska, Alyssa received Bachelors of Science in both Psychology and Animal Science from Iowa State University in 2002. She eventually landed in Washington to earn a Master of Science degree in Experimental Psychology from Central Washington University in 2010. Alyssa conducted research with callitrichid monkeys, chimpanzees and preschool-age humans, before joining the DirectAMS team.
When she’s not on the move, Alyssa can be found knitting with a cat in her lap, baking for the next staff birthday celebration or enjoying a fabulous meal at one of the countless Seattle eateries.
Quality Assurance Administrator / Office Manager
Jacob joined DirectAMS in 2017 to help achieve and maintain quality assurance and quality control to the utmost extent. He is also responsible for managing the growing needs of the office. Having spent a few years as a laboratory analyst for regulated environmental samples, Jacob brings a unique but similar skill set to the radiocarbon office.
Originally born and raised in southern California, Jacob earned his Bachelor’s degree in Earth and Space Sciences from the University of Washington in 2013. While in school, Jacob gained valuable experience in the field with geologic field work and with Cretaceous ammonite fossils.
Tye manages the day to day operations of the lab while primarily being responsible for subsampling, chemical pretreatment, and graphitization. He joined the DirectAMS team in 2017. Born and raised in Coquitlam British Columbia, Tye earned a Bachelor of Science degree in Chemistry from Simon Fraser University in 2009. He founded his career in environmental and research labs, with his latest specialty in the analysis of used petroleum.
Outside of the lab Tye enjoys playing with his dogs, cycling, fishing, kayaking, craft beer and cheering on his beloved hometown Vancouver Canucks.
Anna Joy Thompson
Laboratory Technician I
Hailing originally from Kentucky, Anna Joy, earned her Bachelors of Science in Environmental Science and Sociology from Georgetown College. Making use of opportunities provided by the University of Kentucky to participate in grasslands ecology and plant breeding research groups, Anna Joy developed a taste for the discovery and learning afforded by the laboratory setting. Anna Joy joined the team in October of 2017 to support general lab operations and maintenance, as well as in assistance with sample processing.
Anna Joy’s interest in the environment and sustainable food systems first brought her to Seattle as an AmeriCorps volunteer at North Helpline Food Bank. Her interests are continued through her search for the next great recipe to try, cooking, gardening, reading, volunteering, or discovering her next favorite bubble tea cafe.
Ugo Zoppi, Ph.D. (1965-2016)
Director, AMS Laboratory
Dr. Ugo Zoppi, Ph.D. was a renowned expert in the AMS field, with over 18 years of radiocarbon dating expertise. He served as Director of our AMS facility since its inception in 2006, measuring more than 70,000 samples before his untimely death in March 2016. Ugo was an integral part of the small DirectAMS team, and will be greatly missed. He brought an extraordinary professionalism and playfulness to his work here at DirectAMS.
A native of Switzerland, Dr. Zoppi participated in research at three different world-class AMS facilities (Zurich, Tokyo and Sydney). He obtained his Ph.D. in 1993 from the Nuclear Physics and Astronomy Department, Swiss Federal Institute of Technology (ETH) in Zürich in the lab of Prof. Dr. W. Wölfli and Dr. M. Suter. His Ph.D. thesis was titled, "Isobar suppression in Accelerator Mass Spectrometry."
When he wasn't in the laboratory, Dr. Zoppi was hiking in the nearby Cascade Mountains, or completing a puzzle game in record time.
