Julie Eng
  • Executive Vice President and General Manager of 3D Sensing, Finisar

Julie Eng

Julie Sheridan Eng currently serves as the Executive Vice President and General Manager of 3D Sensing, a business segment of the global technology and engineering leader Finisar. Eng holds a BA in physics from Bryn Mawr College and a BS in electrical engineering from Caltech, and she earned her MS and PhD in electrical engineering at Stanford. She has published over a dozen papers and holds seven patents.

John Sader
  • Research Professor of Aerospace and Applied Physics

John Sader

John Sader joins EAS as a Research Professor of Aerospace and Applied Physics from the University of Melbourne, where he was Professor of Applied Mathematics. John’s research spans many fields, including fluid mechanics, colloid science, plasmonics, mass spectrometry and atomic force microscopy, and he collaborates broadly with experimentalists across the world. John is perhaps best known for developing experimental methods in atomic force microscopy. He has been a regular visitor to Caltech since 2009 and has collaborated with many groups across EAS on nanoelectromechanical systems for mass spectrometry, rarefied gas dynamics, fluid-structure interactions of flags, shape morphing mechanical structures, dynamic stability of thin elastic films for space deployment, and the vortex dynamics of start-up flows. John is an elected fellow of the Australian Academy of Science, the Australasian Fluid Mechanics Society, and the Australian Mathematical Society. His office is in the Firestone Laboratory.

Christopher Yeh
  • Graduate Student, Computing and Mathematical Sciences

Christopher Yeh

I am a G2 in CMS studying machine learning. My main research focus is multimodal representation learning, which involves designing neural networks that can process many types of data at once. As part of my Ph.D., I am also trying to build a community of machine learning researchers who care about environmental sustainability applications, such as using reinforcement learning to reduce carbon emissions in the electricity grid. Although I was born and raised in Southern California, I still find so much to explore around Pasadena and the broader Los Angeles area. I enjoy hiking, camping, biking, skiing, volleyball, ultimate frisbee (go Aftermath!), as well as playing cello in the Caltech Orchestra. If you see me around, ask me about my trip to a remote Alaskan island or my weeklong homestay on a rural Chinese tea farm. Also, I am co-chair of the GSC Sustainability Committee, so if you have any ideas on how to make Caltech a more sustainable environment, let me know!

Ivan Maliyov
  • KNI Postdoctoral Scholar Research Associate

Ivan Maliyov

I received a BS in Applied Physics from the Physical Technical Faculty of V. N. Karazin Kharkiv National University in Ukraine. Then, I obtained an MS degree in Nanosciences from École Polytechnique and Univérsité Paris-Saclay in France. With a double-diploma program, I also received a MS in Medical Physics from V. N. Karazin Kharkiv National University, Ukraine. I obtained a PhD degree in Condensed Matter Physics from Univérsité Paris-Saclay, France in 2019. Starting in December 2019, I joined Caltech as a Postdoctoral Scholar in Professor Marco Bernardi's group. My current research focus is the electron transport and ultrafast dynamics in the presence of external fields in complex materials within the Boltzmann transport equation formalism and time-dependent density functional theory. In my free time, I play the clarinet in the Caltech Symphonic Orchestra and piano in a Caltech Chamber Music ensemble.

Roni Goldshmid
  • Postdoctoral Scholar, Aerospace (GALCIT)

Roni Goldshmid

I am a second-year postdoc in the Dabiri Lab within the Department of Aerospace (GALCIT) at Caltech. I am broadly interested in experimental fluid dynamics, the development of measurement techniques, and leveraging machine learning for imperfect empirical data. My current research project focuses on the development of non-intrusive data-driven and physics-based methods that estimate incident wind speeds from visual observations of natural vegetation. These methods provide physical insights on the flow-structure interactions. Possible applications for these methods include aviation safety monitoring and wildland firefighting. Outside of research, I like to run on mountain trails and watch the sunset on the beach. Finally, after serving as the Caltech Postdoc Association (CPA) EAS representative and CPA treasurer for the last year, I am excited to announce that I am the incoming CPA chair and am looking forward to continuing to serve the Caltech community.

Sean McBeath
  • Postdoctoral Scholar, Environmental Science and Engineering

Sean T. McBeath

I am a postdoctoral scholar in the Department of Environmental Sciences and Engineering. My research interests include the development of water and wastewater treatment technologies for decentralized system applications, primarily involving electrochemical systems and novel materials. I received my bachelor’s and master’s degrees in Applied Sciences in Chemical and Biological Engineering at the University of British Columbia and my PhD at Imperial College London. I also worked as a research associate at RESEAU Centre for Mobilizing Innovation, developing water treatment technologies for rural Indigenous communities in Canada. My journey at Caltech begun in April 2021, helping the team in the Hoffmann lab to develop a point-of-sampling process to detect and quantify SARS-CoV-2 in wastewater, for epidemiological surveillance in developing communities. Away from research, I am an avid runner and cyclist. I was formerly a high-performance athlete, competing for Team Canada in the Olympic sport of sprint kayaking.
