Education and career

Bergman received a B.S. in electrical engineering from Bucknell University in 1988. She received a M.S. in Electrical Engineering in 1991, and a PhD in 1994, from the Massachusetts Institute of Technology.[1] During her graduate work at MIT, she worked with Hermann A. Haus, researching "quantum noise reduction and soliton propagation in optical fibers."[3]

Bergman was an assistant professor of electrical engineering at Princeton from 1994 to 2000.[1] During this time, she led a project funded by NASA and the NSA to test components of an optical communications network for supercomputing.[4]

Bergman went to Columbia as an associate professor of electrical engineering in 2001 and became director of its Lightwave Research Laboratory in 2002.[1] According to her member biography from OSTI's Advanced Scientific Computing Advisory Committee (of which she was a member from 2016 to 2019),[5]

As director of the Lightwave Research Laboratory she leads multiple research programs on optical interconnection networks for advanced computing systems, data centers, optical packet-switched routers, and chip multiprocessor nanophotonic networks-on-chip.

In 2019 a team led by Bergman won a $4.8 million DARPA grant to support the development of a new class of on-chip optical interconnects that scale performance without increasing energy costs.[6]

Returning to the lab in July 2020, after a hiatus caused by COVID-19, Bergman told Columbia Engineering News that her team used the break to find new ways to do informal interactions as well as remote data analysis.[7]

Awards and honors

In 2003 she was named a Fellow of The Optical Society "for seminal contributions to quantum noise reduction and soliton pulse generation".[8]

She was named a Fellow of the Institute of Electrical and Electronics Engineers in 2009 "for contributions to development of optical interconnection and transport networks".[9]

Bergman also won the 2016 IEEE Photonics Society Engineering Achievement Award "[f]or pioneering contributions to optical interconnection networks and photonic-enabled architectures that advance communications and computing systems."[10]
