Katrina Andrews

katrinaandrews[at] ucla [dot] edu

Katrina is originally from the UK and obtained her MSc in Medicinal and Biological Chemistry from the University of Nottingham in 2017. She then spent one year working in hit-to-lead optimisation at a pharmaceutical company in Switzerland before returning to the UK to undertake doctoral studies at the University of Oxford in the group of Prof Stuart J Conway. For her PhD project, Katrina worked on the synthesis and biological evaluation of PROTACs targeting transcriptional coactivator proteins for degradation. In the Backus group, Katrina aims to develop isobaric labelling techniques that will enhance the throughput of chemoproteomic studies. In her spare time, she enjoys exploring new places, socialising with friends, and baking.

​Chau Ngo

UCLA Chemistry and Biochemistry Teacher-Scholar

cdngo [at] mednet [dot] ucla [dot] edu

Chau received her B.S. and M.S. in Chemistry from the University of California, San Diego in 2016 and 2018. Chau then pursued her doctoral study in Chemistry at the University of Southern California in the laboratory of Professor Chao Zhang. Working in multidisciplinary research at the interface of organic chemistry, medicinal chemistry, and chemical biology, Chau’s doctoral research mainly focused on the development of potent and selective small-molecule covalent inhibitors against numerous therapeutic proteins for the treatment of human diseases, including COVID-19 and autoimmune diseases. Following the completion of her doctoral study, Chau excitedly joined the laboratory of Professor Backus as a Donald J. Cram teacher scholar. In the Backus lab, Chau is strongly interested in synthesizing new small molecules as chemical tools to study ligandable proteomes and developing mass spectrometry-based chemical proteomics platforms to conduct comprehensive screening and robust target identification. As a teacher scholar, Chau also teaches general and organic chemistry laboratory courses. In her free time, she enjoys spending time with family, watching tennis, baking, and reading.
