Current group members

Sarah Gold
lab: 509-335-7740

Sarah Gold spent most of her life in Bellevue Washington. She studied at Bellevue college while intermittently traveling to places like Canada, Australia, and Ohio. Currently Sarah is working on a bachelor's degree in genetics and cell biology. For fun, she likes to explore the outdoors, draw, take pictures, and learn new things.

Chase Bethard

lab: 509-335-7740

Chase grew up in Houston, Texas. After graduating from Texas State University in 2009, he conducted physiology research at Dow AgroSciences near Portland, Oregon. When he’s not in the lab, Chase is interested in gardening, mycology, beekeeping, and exploring the outdoors.

Christina Choi

lab: 509-335-7740

Christina was born and raised in Spokane, WA, not too far away from Pullman. She finished her undergraduate studies at Western Washington University and is excited to be a part of the Hellman research group at WSU. Baking, cooking and painting are just a few of her many hobbies. She is always looking to acquire new skills and talents wherever she can. One of her goals in life is to eat her way around the world!

Sutton Mooney

lab: 509-335-7740

Sutton grew up in Raleigh, North Carolina, where she completed her undergraduate degree at NC State. She worked at Duke, UNC-CH, and various other places around the triangle area for a number of years before heading down to Austin, Texas to pursue doctoral work in microbiology. However, she ‘saw the green’ and joined the lab of Mark Estelle , who promptly moved to Bloomington, IN. Having survived 4 years in the mid-west working on auxin-regulated protein degradation, Sutton is happily broadening her scientific endeavors by working on all of the projects in the Hellmann lab. When not at the bench, she is advising undergraduates at WSU who want to go on to medical school. Her main hobby currently is dealing with a rambunctious 6 year old.

  Hanjo Hellmann

    office: 509-335-2762/

    lab: 509-335-7740

Hanjo Hellmann studied biology in Kaiserslautern, Germany, before beginning his PhD thesis in the group of Wolf Frommer (Berlin and Tubingen, Germany). His focus was on sugar and amino acid signal transduction. After graduation in 1997, he continued to work on these topics as a group leader with Wolf Frommer. In 1999 he was awarded a two-year DFG fellowship, and joined the lab of Mark Estelle, then in Austin, TX. Here he began to work on E3 ligases and auxin. In 2002 he went back to Germany and started his own group as an Assistant Professor at the Freie University Berlin. In 2007 he decided to move back to the US and continue his research and teaching at Washington State University. His current scientific interests are located in the fields of metabolism and regulatory pathways that control stress tolerance. Outside of lab he liked to play squash and badminton (which is difficult to do in Pullman), but the region provides great opportunities for bicycling and photography.
