Other mentoring:
I immensely value (peer-) mentoring programs and early-career support networks. I have contributed as a mentor to several mentoring programs and (helped) established several mentoring networks over the past years.
I have served as a mentor in several mentor programs including:

Miranda Harkess (right) and me at the Center For Astrophysics – Aug ’21
Mentoring with applying to PhD programs
I have written numerous resources for applying for Ph.D. positions in Astronomy, and every year I support ~10 students with their applications by discussing the application timeline, providing feedback on written essays, and giving advice regarding offers and rejections.
