Caltech Senior Wins Gates Cambridge Scholarship

Catherine Bingchan Xie, a senior bioengineering major and English minor at Caltech, has been selected to receive a Gates Cambridge Scholarship, which will fund her graduate studies at the University of Cambridge for the next academic year. Xie, a Canadian citizen, is one of 51 new international recipients selected from a pool of more than 4,000 applicants based not only on intellectual ability, but also on leadership capacity and a commitment to improving the lives of others.

As a Gates Cambridge Scholar, Xie, 20, will pursue a Master of Philosophy in translational medicine and therapeutics. "The research program and the knowledge that I'm going to gain will provide me with an essential foundation for becoming a physician-scientist, translating research findings in the lab into revolutionary therapies," she says. "I'm really excited to join the Gates Cambridge community and be surrounded by people like me who want to make an impact on other people by taking on important roles and issues in society. I think the energy and enthusiasm of rising toward this common goal will be really invigorating."

Having lived in China, Australia, Canada, and the United States, Xie has been exposed to a variety of cultures—something that she says motivated her to want to become a highly involved leader in a diverse and multicultural society.

As an undergraduate student, Xie has taken full advantage of opportunities to pursue research projects in the laboratory with outstanding scientists. During her freshman year, she began working in the lab of Frances Arnold, the Dick and Barbara Dickinson Professor of Chemical Engineering, Bioengineering and Biochemistry, engineering ways to improve the thermostability of enzymes used to make biofuels. The summer following her sophomore year, Xie joined the lab of C. Garrison Fathman, professor of medicine and chief of the Division of Immunology and Rheumatology at the Stanford School of Medicine, to study a novel transcription factor regulator involved in the pathogenesis of Type I diabetes. When she returned to Caltech, she immediately joined the lab of David Baltimore, the Robert Andrews Millikan Professor of Biology, where she is currently working. There, her research focuses on microRNAs—tiny snippets of RNA that are only about 20 nucleotides long—and the regulatory role they play in the development of leukemia. 

"Catherine is a student with broad interests, an engaging personal style, and great effectiveness," Baltimore says. "She has been a pleasure to have in the laboratory, and I am not surprised that she has won this prestigious scholarship and chosen to broaden her knowledge by focusing on public health issues while she is at Cambridge."

Xie says her ultimate goal in life "is to be able to not only improve our understanding of disease mechanisms, but also to be able to use that understanding to create novel, innovative therapies in order to help people battle their diseases."

Xie's desire to help others was clear during her time at Caltech—she led Caltech Y service trips, during which she and other students helped to rebuild houses for low-income families, assisted in beach and riverbed cleanups, and worked at a homeless shelter. As a freshman, she started the annual Caltech Student Health Fair to make students more aware of the physical, mental, and emotional health resources on campus and throughout the community. She has also served on campus as the vice chair of the Academics and Research Committee and as a member of the Caltech Y Student Executive Committee.

"I'm so excited that Catherine has been chosen to receive this fellowship," says Athena Castro, executive director of the Caltech Y. "I just love her. She's enthusiastic, dedicated, positive, thoughtful, and committed."

In the summer of 2012, Xie broadened her horizons even more when she traveled to Switzerland as a recipient of Caltech's SanPietro Travel Prize. "Catherine demonstrated her ability to adapt quickly and truly engage in another culture on that trip," says Lauren Stolper, director of fellowships advising and study abroad. "She will represent Caltech well as a Gates Cambridge Scholar."

Xie says she is thankful to everyone who has contributed to her experience at Caltech. "My achievements wouldn't have been possible without people giving me opportunities, encouraging me, and providing me with feedback, allowing me to grow as a scientist and as an individual," she says. "Caltech has shown me that intellectual curiosity and passion are vital driving forces behind finding innovative solutions that will have a profound and meaningful impact on solving issues that confront society."

The 51 newly announced international scholars will join 39 new American Gates Cambridge Scholars. The Gates Cambridge Scholarship program was established in 2000 through a donation from the Bill and Melinda Gates Foundation to the University of Cambridge. Xie is the sixth Caltech undergraduate student to receive the fellowship.
