Reflection: Starting a Shift to a New Career in Transportation Policy

This post is the second in a series of three posts about the end of my time as a PhD student in Princeton University (in this post henceforth referred to simply as "the university"). As a write this, I am still technically a PhD student enrolled full-time in the university, working on topics in nanophotonics & fluctuational electromagnetics. Next fall (assuming the current public health crisis abates to an extent that it is safe for me to do so — please note that I am not a public health expert or epidemiologist, so I am not making predictions in this regard), however, I will start a postdoctoral research position in the University of California Davis analyzing transportation policy, with a particular eye toward the effects of such current & future policies on the mobility and resulting socioeconomic opportunities for those who have been marginalized by current transportation systems, including people who are poor or have disabilities (like myself). This is a fairly drastic, and arguably surprising, change of career; I have told many friends and relatives about this, but not all of them, so I'd like to use this space to explain my thought process over the years leading up to this decision.
