Qi Yu (Bowman Group) Receives Award from China Scholarship Council

Fifth year graduate student Qi Yu (Bowman Group) has received an award from the China Scholarship Council. The award is considered the highest honor given by the Council in recognition of a student conducting graduate studies outside of China who does not receive financial support from the Chinese government.

To date, the recipients include students studying in 33 countries, including the United States, the United Kingdom, Germany, Japan, Australia and Canada. More than half a million Chinese students leave China to study abroad each year, making this prestigious award highly competitive, with only 500 students awarded yearly. The award includes a one-time $6000 cash award and a certificate.

“Qi has done outstanding work on the quantum dynamical description of protonated water clusters, from the potential to the vibrational dynamics.  He has joint papers with top experimental groups in the world working in this research area,” says his Ph.D. advisor, Dr. Joel Bowman.

Congratulations, Qi!

Alumni Career Seminar: From Science to Snapchat

Xiaohong Wang

On Friday, September 29th, the Department of Chemistry welcomed back one of our distinguished alumni, Dr. Xiaohong Wang. Since earning her PhD in Chemistry, Dr. Wang has been working as a software engineer with Snap Inc. During her talk entitled “First Impression of Working in Industry- From Chemistry PhD Student to Engineer at Snap Inc.”, Dr. Wang outlined her professional journey and gave us a peek into her life as a Snap Inc. software engineer.

Dr. Wang earned her Bachelor’s degree in chemical physics from the University of Science and Technology of China. From there, she joined the Emory community and completed both her Master of Science in computer science and her Doctor of Philosophy in computational science in the Bowman Group before taking up her position at Snap, Inc.

Snap Inc.—makers of the popular “Snapchat” app—is a camera company founded in 2011 that believes “reinventing the camera represents our greatest opportunity to improve the way people live and communicate.” Snapchat is used by over 150 million people every day to connect with others all around the world. The company is constantly working to build and develop the best platform for communication and storytelling. Software engineers like Xiaohong contribute to this vision by evaluating the technical tradeoffs of decisions, performing code reviews, and building robust and scalable products.

The transition from chemistry to computer science, although seemingly a major change in profession, turned out to be quite a natural one for Dr. Wang. During her graduate studies in chemistry, she received training in numerical techniques, data analysis, programming, writing, and problem solving. These skills have proven to be invaluable for her engineering position with Snap, Inc., and she credits much of her success as a software engineer to the training she received during her time at Emory. For instance, during the interview process, Dr. Wang was asked to write a program on her own computer—something that came naturally thanks to her PhD work.

Perhaps more difficult than the change in profession was the transition from graduate school to industry. “There are many things we need to learn, like new techniques, how to communicate with managers and colleagues, and how to adjust our expectations,” Dr. Wang said. She explained that her current position relies heavily on teamwork and maintains a fast working pace in a way that is very different from graduate school. Xiaohong also shared that she is the only woman on her particular team at Snap, Inc. Overall, she finds the environment welcoming and has developed relationships with fellow women in tech.

Overall, while this transition from graduate school to industry required her to acquire a new set of skills and adapt to a new environment, Dr. Wang has hit her stride with the company. Having spent several months working on the company’s first piece of hardware, Spectacles that let users take photos directly from the frames, Dr. Wang said, “The launch of the product is really exciting for the whole team, the whole company, and I feel very proud to be part of it.”

The Emory Department of Chemistry is fortunate to have an amazing group of alumni who have gone on to pursue impressive careers in a variety of fields. The successes of these individuals remind us how capable we are of reaching our own goals and motivate us to continue chasing our dreams. Thank you to Dr. Wang for taking the time to visit Emory and share her journey with us!

This special seminar was made possible via support from the Emory Laney Graduate School Alumni Office.

Joel Bowman and graduate student Xiaohong Wang are authors of the article, “Unimolecular dissociation dynamics of vibrationally activated CH3CHOO Criegee intermediates to OH radical products,” which was recently published in Nature Chemistry.  The paper is the result of a collaboration with Marsha Lester’s group at Penn and explores the diurnal production of atmospheric OH–” the ‘detergent’ of the troposphere because it reacts with many pollutants” from the so-called Criegee intermediate.
