Joel Levitt BS'59, MS'60, Eng'65 writes: “After receiving my BS in 1959, I stayed at Columbia for my MS in electrical engineering, my MA in physics, and my EE (professional degree). I taught at Pratt Institute and became their leading developer of course-related software (FORTRAN, BASIC) until their School of Engineering closed in 1993. I stayed at Pratt to teach physics and computer programming (C, C++, JAVA) until I retired in 2014. I am most proud of my general nodal-analysis program in Basic. Most said it couldn’t be done due to the lack of native complex variables, but my routine for evaluating an NXN-complex determinant was more immune to under/overflow than commercial programs in other languages. My present almost-finished project is a mouse-free drawing program (Processing) that allows precise control of multiple moving shapes (e.g., rotating polygons changing size and color) with no hand dexterity required. Any interest in beta testing? Email [email protected].”

Neil Marmor BS'64, MS'67, EE'69 writes: “Class of ’64? Impossible! But life is good, per my three ‘prime parameters’: I am in good health (for my age), I can still find my car after parking at the mall, and I can pay my rent every month. Occasionally, I look at the few textbooks I have saved and wonder how I ever passed Theory of Nonlinear Networks by T. Stern. I must have been a hard-working undergraduate. I continue to read to little kids and assist with getting situationally homeless people back on their feet. The culture scene in San Diego is good (though it’s not New York City). I have some good friends. I read at least one or more books per month (try The Happiness Curve—it provides a gratifying spin on youth, middle age, and the ‘golden years’). I am indeed living long and prospering, which makes me one very fortunate fellow. If you’re ever in San Diego, let’s swap stories and catch up.”

Josh Radoff MS'99 writes: “I lead WSP's national (US) built environment sustainability team.

David Small BS'89, MS'91 writes: “Thirty years since I graduated, I came back to campus this past May for my son Aren’s graduation from SEAS. The campus looks much the same, but some things have changed. For one, while the bookstore is still there, FBH and the Plex are gone, replaced by Lerner Hall. Where do engineers party now? Aren tells me Mudd!”

Irwin Studen BS'82, MS'85 writes: “It's been a long time since I've provided an update, owing mainly to my career outside of engineering. After 25+ years as a CFO primarily in the tech sector, I'm happy to report that I've transitioned into semi-retirement mode by focusing the last few years on CFO consulting and income-producing property investment. My company recently closed on our first deal in the DC metro area and we're looking forward to exploring other opportunities. On the personal side, my wife Doreen and I have four great kids from our prior marriages and all but one are out of college on their own and doing well. Thirty-seven years sure does go fast.”

Brian Swain BS'85, MS'87 writes: “I've just published my eighth book, a short story collection titled The Book of Names. I look forward to hearing your comments about it, and thanks in advance for checking it out.”

Ali Taslimi MS'85, EE'89 writes: “Since graduating from the Engineering School, I have enjoyed a rich and fulfilling career.

The company is currently based in New York City. Please get in touch if you are excited about the idea and want to contribute!”

Matt Petersen MS’18 writes: “Following graduation, I worked at an AI startup extracting information from scanned legal documents. The most memorable times were overlooking New York from the 42nd floor of Goldman Sachs, seeing Amsterdam for a deployment, and visiting our main office in London. I was really lucky to have gotten that job and still keep in touch with my old team. Now I’m at a similar startup that acts as a loan data provider for many of the same clients. Both of these jobs have been amazing, and I couldn’t be happier with my career and the people I get to work with every day.”

Kasumu Salawu MS’69, EngScD’72 writes: “I started conducting research at AT&T Bell Telephone Laboratories in 1972, a day after I was awarded a doctorate degree in the Department of Industrial Engineering at Columbia University. Simultaneously, for more than a decade, I taught engineering courses at Rutgers University. From 1975 to 1977, I was a senior lecturer at the University of Lagos, Nigeria. I returned to the US to work on a port decongestion project for Nigeria at MIT. In the nine months I was there, I earned another master’s degree in civil and environmental engineering. I returned to both Bell Labs and Rutgers and consulted in database technology on Wall Street and at Delta Airlines and BellSouth here in Atlanta. Ten years ago, the Centers for Disease Control and Prevention came calling. Starting with biosurveillance research at CDC, I branched into artificial intelligence doing algorithmic machine learning and game theory.”

Vinayak Shinde MS'19 writes: “Professional update: I have joined Societe Generale as an associate in the risk department. My primary focus is analysing the counterparty default risk of our clients.

J. Victor Stern MS’73 writes: “After 33 years with Sikorsky Aircraft and 10 years of running my consulting company, Global Pursuits LLC, I am retiring.”

Harold Weitz BS'51, MS'54 writes: “I graduated high on the academic scale including honors, but found getting a job difficult. The guys in my class all had jobs lined up. Was being Jewish still a problem in engineering? I then took a temporary job in the planning department of Wright Aeronautical. At the end of the summer I went back to Columbia as a graduate assistant and to pursue an MS degree. Shortly after this, Uncle Sam called and I went into the service and worked at the US Army Proving Ground evaluating tank effectiveness. I married and went back to industry not long after. I worked at long range planning and military R&D with the Bulova company. In 1964, I started with IBM, which was a great company then and still is (but not as great). I spent a good chunk of my time there in network design and performance on one of the the world’s largest networks. In the 28 years I was with IBM, I consider working on a project that should have resulted in an ‘AOL’-like company my best work. But after studying the project for almost a year and the expenditure of a million dollars, the project was killed. Why? It was too different from what the company was doing.”

Guangbing Xu MS’17 writes: “I just celebrated my second anniversary at Amex, got my PADI Open Water certification, and finished an 11-hour hiking trail!”

Yi Zhang MS'19 writes: “I have been working at Morgan Stanley since March, and as a strats, I feel like I have improved on a lot of skills. Since our work is project-based, we need to consider the long-run plans, potential needs in the future, and potential problems we may face. It is a different experience from doing projects at school. In addition to the work, I also traveled to Taiwan in April. Since I love climbing mountains, I intended to climb Mount Yu in Taiwan, but due to some unexpected issues, I didn't go there. Instead, I went to a small island called Lanyu. It is a beautiful island with an ancient style. The people on the island maintain the traditional lifestyle. I highly recommend it.”

Yuyang Zhou MS'19 writes: “I am looking for my first job. I believe it will be wonderful.”
