Yuh Nung Jan

At the time, both of the Jans were interested in pursuing advanced studies in theoretical high-energy physics and applied to graduate school abroad.

However, research seminars at Caltech and a conversation with Max Delbrück, a winner of the 1969 Nobel Prize, inspired Yuh Nung to switch fields to biology.

[3] Although he was in the same thesis lab as Lily Jan, their research paths were distinct and they would in fact not begin their life-long scientific collaboration or publish together until after they graduated Caltech with their degrees.

As he approached graduation, Yuh Nung would come across a publication by the scientist Seymour Benzer detailing opportunities associated with correlating fly embryo morphology with functional behavior.

In preparation for this shift in research, he and Lily Jan spent a summer at Cold Spring Harbor learning techniques in experimental neuroscience.

A series of mutant flies, named Shaker, with uncontrolled muscle contractions proved crucial to these endeavors and set the stage for some of their most significant contributions in the field of neuroscience.

Remarkably, Lily Jan was still involved in research leading up to her due date and went into early stages of labor in the midst of Seymour Benzer's group meeting.

[1] Just seven weeks later after celebrating the arrival of Emily, the Jans would move across the country to begin the next stages of their research careers at Harvard Medical School.
