Alumni Updates '19-'20

Sean Blanton (BS ‘91, Applied Physics) is moving to Citadel, LLC, after four years at proprietary trading startup Radix Trading, LLC. Both firms are in Chicago. Originally published by Columbia Engineering Magazine

Dr. Thomas Caulfield (PhD '86, Materials Science and Engineering) is the CEO of Globalfoundries. Prior to being named CEO, he was the Senior Vice President and General Manager of the company’s leading-edge 300 mm semiconductor wafer manufacturing facility (Fab 8), located in Saratoga County, NY. Caulfield, who joined the company in May 2014, led the operations, expansion and ramp of semiconductor manufacturing production at Fab 8. He recently connected with Prof. Siu-Wai Chan when she visited to present a talk at Globalfoundries.

Xinpei Geng (MS’19, Materials Science & Engineering) writes: “After graduating from Columbia, I joined Huawei as a chip engineer—it’s a critical time because the company’s facing a lot of pressure from the US government. I’m now working on the development of a CPU chip for servers, and traveling is a part of my life. I do believe what I learned from Columbia can help me go through all these difficulties.” Originally published by Columbia Engineering Magazine

Ed Gerstenhaber (BS ‘68, Nuclear Engineering) writes: “I recently finished my first season working as an AARP volunteer doing tax returns for seniors and low income people. I am in my ninth year as a ‘standardized patient’ (definition on Google if you’re curious) for the University of Pittsburgh School of Medicine. And then there’s biking!” Originally published by Columbia Engineering Magazine

Anthony Gong (BS ‘15, Applied Mathematics) is enrolled in a master of science program. Originally published by Columbia Engineering Magazine

Siyang Liu (MS '19, Materials Science & Engineering) wrote: "After graduation, I joined Huawei Corporation as a Product Manager and now I'm working on marketing and solution selling of telecom product in North Africa. Our mission is to provide African people with a better connected world and bring customers business success. Life in Columbia and APAM offered me global vision as well as sense of mission, which fully correspond to the slogan of Huawei: To build a fully connected intelligent world."

Manju Prakash (PhD ‘85, Applied Physics) writes: “I was invited to participate in the 2019 summer research program on turbulent life of cosmic baryons at the Aspen Center for Physics in Aspen, Colorado. This provided me an opportunity to investigate the history of the early universe using primordial gravitational wave signals generated by the hydro-magnetic turbulence excited in the early universe, potentially carrying imprints of the processes that took place microseconds or less after the universe was born. The meetings took place in the scenic mountains where participants focused on exploring new ideas and forging collaborations for future research in plasma turbulence.” Originally published by Columbia Engineering Magazine

William Quirk (BS ‘67, Applied Physics) was elected in 2018 to his fourth two-year term in the California State Assembly. He represents Southern Alameda County in the East San Francisco Bay Areas. He is running again in 2020. Originally published by Columbia Engineering Magazine

Andrew Salthouse (BS’ 69, Nuclear Engineering) retired in 2016 after 40 years as a lab assistant and junior analyst. Originally published by Columbia Engineering Magazine

Changmin Shi (MS ’19, Materials Science & Engineering) writes: “Since graduating from Columbia, I have been a PhD student at the Department of Materials Science and Engineering at the University of Maryland, College Park. Columbia Engineering indeed cultivated in me the critical thinking and problem solving skills that I need to pursue my PhD and future career goals. I would like to take this opportunity to give thanks to materials science and engineering professors at Columbia for giving me such excellent skills and igniting my passion for my research in the future.” Originally published by Columbia Engineering Magazine

Robert Siegfried (MS ’78, Metallurgy) writes: “I’m still a full professor at Adelphi teaching computer science. My son, Jason, is graduating from Adelphi in computer science (of course) this January. My wife, Kathy, Jason, and I continue to live in Oceanside on the south shore of Long Island after weathering Superstorm Sandy.” Originally published by Columbia Engineering Magazine

Jingyi Zhuang (MS ’19, Materials Science & Engineering) entered the Columbia Department of Earth and Environmental Sciences. Originally published by Columbia Engineering Magazine

Geng-Wei and En-Yu, who were both advised by Prof. Chan during their graduate studies at Columbia Engineering, have been working in Taiwan for 10 years. En-Yu currently works at Industrial Technology Research Institute (ITRI), a government research lab, and Geng-Wei works at Enerage, Inc., a graphene manufacturing company, in Yilan, Taiwan.
