Graduate school is never easy, but as I neared the end of my first year, my Ph.D. training was about to get much harder. It wasn’t that the classes or research were any different. I had simply come to recognize the truth about myself: I was nonbinary, a gender identity sometimes falling under the transgender umbrella. Excited to finally express my true self, I came out to my colleagues and began to pursue my transition. Here I will share some lessons from my own experience as a transgender STEM Ph.D. student in an effort to show other transgender and gender-nonconforming students that they are not alone, as well as to demonstrate ways in which school administrators, faculty and mentors can be better allies and promote the success of transgender students.
