Deborah Chung (BS '73, MS '73)

3D metal printing monitored without using sensors

In spite of its explosive market growth, 3D metal printing is challenged by the thermal stress resulting from the high printing temperatures and the layer-by-layer nature of the printing. The stress commonly results in warpage and inadequate bonding between the layers. Therefore, real- time monitoring of the printing is greatly needed to provide better control and a record of the printing. Cameras commonly used for the monitoring is inadequate for looking at the interface between the layers.  A new invention by Professor Deborah D.L. Chung of the Department of Mechanical and Aerospace Engineering, University at Buffalo, The State University of New York, is about to transform the monitoring technology. This invention unprecedentedly provides monitoring without using any sensor, as the printed layers sense themselves.  The self- monitoring is enabled by the measurement of the capacitance of the metal printed object as the printing proceeds. The measurement of the capacitance of a metal is unprecedented in the world of science, due to the electrical conductivity of a metal. For the self-monitoring, there is no need to modify the printed layers.  The advantages of self-monitoring compared to the use of sensors are low cost, high durability and installation simplicity.  A patent is pending and the technology is available for licensing. The work is described in a paper just published in Sensors and Actuators A. The paper is co-authored by Sanjaya Somaratna, an undergraduate student.

Chung is the foremost scientist in the world in the field of structural self-monitoring, having worked in this field for about 25 years, with smart concrete being her most well-known prior invention. She received her B.S. and M.S. degrees from Caltech in 1973, being one of the four first woman graduates of Caltech.  She received her Ph.D. degree in Materials Science from MIT in 1977.

Ari Kaplain (BS '92)

After creating and leading the Chicago Cubs analytics department, they finally won the World Series and it was great to be part of the journey along the way. I moved over to the Baltimore Orioles to rejoin my first boss I had after graduating Caltech (Dan Duquette), and have had the best record in the AL working with a smaller budget than the big markets. Aside from that I enjoy all things data science, and spending time with my family (kids are now 13, 12, 11 yrs).

Thomas Santoro (MS '69, PhD '77)

Retired for over six years, but still maintain the swimming and diving skills I learned back in the CIT scuba program in Pasadena. Now I just free-dive off the light house at my local beach in Watch Hill, Rhode Island as in the photo. Not as interesting as those great dives off Catalina, but I still love it.

Lisa D. Zhang (BS '10)

I am an Intellectual Property Litigation Associate Attorney at Wilson Sonsini Goodrich & Rosati.  It's been great - we represent technology companies in enforcing their intellectual property rights or defending against the claims of others.  My cases have touched upon pharmaceutical drugs, genetic testing kits and methods, commercial UAVs, network routing and security, caching, LEDs, and image sensors, to name just a few areas.  In fact, one of our clients is Caltech!

Leslie Rusch (BS '80)

After 10 years in government (project management engineer), I returned to graduate studies at Princeton in 1990. With my newly minted PhD, I took a position as a professor at Univ. Laval (UL) in Quebec City. I perfected (well, not really that perfect) my French for teaching at this francophone institution. I work in optical communications with a very active research program. I spent two years (2000-2002) at Intel in Silicon Valley, but ultimately returned to academic life. My husband is also an EE prof at UL and we have two daughters. Our daughters are both studying engineering at McGill (computer and software) - proving the apple does not fall far from the tree. My connection to Caltech has waned over the years - but at least I still watch Big Bang Theory and key my ear for the nerdy jokes.

Martin Pall (BS '68)

I have published 6 papers on how microwave/lower frequency EMFs impact the cells of our bodies.  They activate voltage-gated calcium channels via a mechanism involving both physics and biology.  This leads, in turn, to a wide variety of impacts on the brain, the heart, the reproductive and endocrine systems; it also leads to oxidative stress and cellular DNA damage. There are also therapeutic effect.  EMFs act in plant cells via very similar mechanisms to the action in animal cells.  Since my first such paper in 2013, I have given 38 invited professional talks on this topic in 10 countries.  This is a stunning falsification of the industry propaganda which claims these EMFs only produce thermal effects.

Parker MacCready (MS '86)

I'm at the same job I have had my whole career, studying physical oceanography.  Lately my work has become more applied, developing realistic forecasts models of Ocean Acidification and Harmful Algal Blooms that are used by shellfish growers (http://faculty.washington.edu/pmacc/LO/LiveOcean.html).  The beauty and mysteries of fluid mechanics still hold my attention, so it's a good job.  My wife, Molly, and I live out in the country near Olympia, WA.  Our children are moving along: Jillian just graduated from Claremont McKenna, and Henry starts as a Freshman at Occidental in the Fall.

Richard Smyth (BS '51)

It is a good idea to try to collect information about our classmates.  My wife is the Alumni Notes editor for her class (1952) at Occidental.  She has found the long-time graduates don't respond well to internet notices.  They often do not have access to email and/or forget to look at their email.  They move to retirement homes and forget to re-establish their email address.
I am living in Lompoc, CA, which has the best climate of anywhere in the world.    My wife is here with me.  We have 5 grown children.  They have 12 children (grand children).  They have 6 children (great-grand children) with another one due this week.

Thomas Blaschko (BS '71)

Tom Blaschko's latest book, "We All Have Souls and I Think We Can Prove It," was released June 21, 2017. The book looks at evidence for souls from many sources and proposes a model that is compatible with Western Science. Well, almost compatible. We can keep all the science we have now and only need to add a new force that Tom calls life force. (It has other names in other cultures, such as Ki in karate.) Then we also need to consider the part of ourselves that interacts with the life force. That part has a lot of names, too, but Tom prefers a simple one: soul. The result is a system that respects some well-done science in soul reality and also offers an underlying model that makes sense of the millions of reports of ghosts, angels, precognition, and other phenomena that have been dismissed as impossible using the current Western science model. More information is available on the weallhavesouls.com website.
