Dear Professor ____, 
I am writing to you to recommend Jane for admission into the PhD program at your esteemed university. Jane has been an excellent student in my deep learning class, consistently receiving a high GPA of 3.8. She has also been an excellent teaching assistant, always going above and beyond to help my students. Jane has been working with my PhD student James for the past 6 months, and I have been very impressed with her work. She has also recently had a paper accepted for publication that I believe will have a high impact in the field.  Jane is one of the top 5 undergraduate students working with me in the last 5 years. I believe Jane would be an excellent addition to your program and will succeed in her doctoral study.
