in 1985 and 1988, respectively. For his PhD he focused on developing high-resolution optical microscopes that could see past the theoretical limit of 0.2 micrometers.
Career
Bell Laboratories
After receiving his doctorate, Betzig was hired by
AT&T Bell Laboratories
Nokia Bell Labs, commonly referred to as ''Bell Labs'', is an American industrial research and development company owned by Finnish technology company Nokia. With headquarters located in Murray Hill, New Jersey, Murray Hill, New Jersey, the compa ...
in the Semiconductor Physics Research Department in 1989. That year Betzig's colleague, William E. Moerner, developed the first optical microscope that could see past the .2 micrometer limit, known as the
Abbe limit
In optics, any optical instrument or systema microscope, telescope, or camerahas a principal limit to its resolution due to the physics of diffraction. An optical instrument is said to be diffraction-limited if it has reached this limit of res ...

. Inspired by Moerner's research, Betzig became the first person to image individual fluorescent molecules at room temperature while determining their positions within less than .2 micrometers in 1993. For this he received the
William O. Baker Award for Initiatives in Research (previously known as the National Academy of Sciences Award for Initiatives in Research).
Betzig was also awarded the

Ann Arbor Machine Company
In 1994, Betzig became frustrated with the academic community and the uncertainty of the corporate structure of Bell Laboratories, prompting him to leave both. He spent some years as a
stay-at-home dad before reentering the workforce in 1996, when he took up the position of vice president of

at Ann Arbor Machine Company, which was partially owned by the Betzig family.
Here he developed Flexible Adaptive Servohydraulic Technology (FAST), but after spending millions of dollars on development he only sold two devices.
Return to academia
In 2002, Betzig returned to the field of microscopy and founded New Millennium Research in
Okemos, Michigan. Inspired by
Mike Davidson's work with fluorescent proteins, he developed photoactivated localization microscopy (PALM), a method of controlling fluorescent proteins that used pulses of light to create images of a higher resolution than were previously thought possible. In the living room of his old Bell Labs collaborator
Harald Hess, Betzig and Hess developed the first optical microscope based on this technology. They built their first prototype in under two months, earning them widespread attention. In October of that year, the

Janelia Farm Research Campus hired him, but his lab was still under construction at the time.
In early 2006, he formally joined Janelia as a group leader to work on developing
super high-resolution fluorescence microscopy techniques. He used this technique to study the division of cells in human embryos.
In 2010, he was offered the
Max Delbruck Prize, but he declined it and
Xiaowei Zhuang received the award. In 2014, Betzig was jointly awarded the
Nobel Prize in Chemistry
