Education

edit

Vrielink earned a Bachelor of Science in Chemistry and Masters of Science in Physical Chemistry at the University of Calgary in Canada.[2] For her master's research she worked on ligands of angiotensin, a hormone involved in regulating blood pressure.[3] She received a PhD in 1989 from the University of London where she worked on the structure of cholesterol oxidase.[4] She also has a Diploma in Crystallography from the Imperial College of Science and Technology.[2]

Career

edit

Vrielink was an Assistant and Associate Professor at McGill University in Canada from 1994 to 2001.[2] From 2000 until 2007 she served as a Research Professor at the University of California, Santa Cruz and then joined the faculty at University of Western Australia as Professor of Structural Biology in 2007.[2]

Vrielink was a member of the 2014 National Committee on Crystallography[5] She is a past president of the Society of Crystallographers of Australia and New Zealand (SCANZ).[6]

Research

edit

Vrielink conducts research in protein biochemistry and crystallography with a special focus on understanding the structural determinants governing enzyme chemistry.[7] Vrielink's early research centered on the three-dimensional structure of the enzyme cholesterol oxidase first in Brevibacterium[8][9] and then in Streptomyces.[10]

She has been involved in projects that have established the structure of compounds including L-amino-acid oxidase,[11] prions,[12] and snake venom.[13] In 2017, she mapped the molecular structure of EptA,[14] a protein that shields superbugs from antibiotics. This work has been covered by the BBC,[15] ABC,[16] Times Higher Education,[17] The West Australian,[18] and Particle.[19] Subsequent work on EptA has revealed why it may be a good target for drug development.[20][21]
