Subject: Prospective PhD Inquiry: Machine Learning for Drug Discovery - San Zhang
2

3
Dear Professor Smith,
4

5
My name is San Zhang, and I am currently a senior undergraduate majoring in Computer Science at [University Name], with a strong research focus on geometric deep learning and molecular representation. I am writing to express my enthusiastic interest in joining your research group as a PhD student in the Fall 2026 cohort.
6

7
I have closely followed your laboratory's pioneering work on invariant graph neural networks. In particular, I was inspired by your recent 2025 Nature Machine Intelligence paper on SE(3)-equivariant molecular conformation generation. In my undergraduate thesis, I developed a lightweight tensor-product attention mechanism that improved the docking accuracy of small molecules on benchmark datasets by 8.4% while reducing inference latency by 20%. I believe my computational background in equivariant neural networks aligns closely with your group's current exploration of macrocyclic peptide binding dynamics.
8

9
I have attached my academic CV and my first-author preprint for your review. If your laboratory has prospective openings for Fall 2026, I would deeply appreciate the opportunity to have a brief 15-minute conversation via Zoom to discuss how my skillset could contribute to your upcoming research projects.
10

11
Thank you very much for your valuable time and consideration.

Sincerely,

Subject: [CS280] Extension Request for Final Project Report - San Zhang (ID: 88776655)
2

3
Dear Professor Davis,
4

5
I am writing to respectfully request a short two-day extension on the final project report for CS280 (Computer Vision), which is currently due on Friday, April 17, at 11:59 PM.
6

7
Earlier this morning, I was diagnosed with acute gastroenteritis at the University Health Center and have been advised by the physician to rest under medical observation for the next 48 hours. I have attached the official medical excuse note from Dr. Johnson for your records.
8

9
To ensure my project remains fully on track, I have already completed all experimental simulations, ablation studies, and figure generation. The remaining work consists solely of drafting the ablation discussion and formatting the final camera-ready PDF. If granted an extension, I will submit the complete report no later than Sunday, April 19, at 11:59 PM.
10

11
I completely understand the strict grading timeline for the course staff and genuinely appreciate your flexibility and compassion during this unexpected health situation.

Warm regards,

Subject: [ECON 101] Absence Notification - San Zhang (Lecture on Oct 14)
2

3
Dear Professor Roberts,
4

5
Please accept this email as notification that I will be unable to attend today's ECON 101 lecture (Monday, October 14, 2:00 PM - 3:30 PM) due to a sudden severe fever and respiratory symptoms. Per campus public health guidelines, I am self-isolating while awaiting testing results.
6

7
To ensure I do not fall behind on the curriculum:
8
1. I have already arranged with my study partner, Alex Miller, to borrow his comprehensive lecture notes.
9
2. I plan to thoroughly review the lecture slides and assigned readings on Chapter 6 prior to Wednesday's discussion session.
10
3. If I have any questions regarding the mathematical derivations of consumer surplus, I will attend your scheduled office hours this Thursday.
11

12
I have attached the formal clinical appointment confirmation for your administrative attendance records. Thank you very much for your understanding, and I look forward to returning to class as soon as I am cleared.
13

Best regards,

Subject: [MATH 221] Inquiry Regarding Final Exam Question 4 Grading - San Zhang
2

3
Dear Professor Anderson,
4

5
I hope this email finds you well. I am writing to respectfully ask if it might be possible to review the grading on Question 4 (Singular Value Decomposition) of my recent final examination paper.
6

7
First and foremost, I genuinely enjoyed your lectures this semester and learned an immense amount from your linear algebra curriculum. In reviewing the published exam solution key, I noticed that on Question 4(b), my derivation arrived at the correct orthonormal singular vectors and final singular values. However, I received a deduction of 12 out of 20 points.
8

9
Upon carefully re-examining my scratchwork alongside the textbook's Theorem 4.3, I believe my methodology employed the alternative Gram-Schmidt orthogonalization path rather than the eigendecomposition approach shown in the rubric, which led to identical analytical results through an alternative valid trajectory.
10

11
I would be immensely grateful if you or the head teaching assistant could spare 10 minutes during your post-semester office hours next week to help me understand where my mathematical logic diverged or if a partial credit adjustment might be warranted under the course grading rubric.
12

13
Thank you very much for your dedication to our learning and for your guidance throughout this academic year.

Sincerely,

Subject: Letter of Recommendation Request for Graduate Admissions - San Zhang
2

3
Dear Professor Williams,
4

5
I hope your semester is wrapping up smoothly. I am writing to respectfully ask if you would feel comfortable writing a strong letter of recommendation for my upcoming applications to Master of Science programs in Biomedical Informatics for Fall 2026.
6

7
I had the distinct privilege of taking your advanced course, BIOENG 250 (Computational Genomics), in Spring 2025, where I achieved an A grade and had the opportunity to lead our term project on deep learning for splice junction detection. Your thoughtful mentorship during our bi-weekly project check-ins deeply solidified my aspiration to pursue a career in computational biology research.
8

9
I am planning to apply to approximately five institutions, with the earliest deadline falling on December 15, 2025. To make this process as convenient for you as possible, I have compiled a comprehensive recommendation packet via the attached Google Drive link, which includes:
10
- My updated academic CV and unofficial transcript
11
- A draft of my Statement of Purpose detailing my research objectives
12
- A concise summary table of target universities, program deadlines, and specific projects from your course that I highlight in my essays
13
- A bulleted list of my core project contributions and presentation milestones
14

15
I completely understand that your schedule is exceptionally demanding at this time of the academic cycle. If you feel you are not in a position to provide a strong recommendation, please do not hesitate to decline, and I will be entirely understanding.
16

17
Thank you so much for your continuous guidance, support, and profound influence on my academic journey.

Warmest regards,

Dear Professor Smith,

5
I hope you are having a productive week.
6

7
I am writing to briefly follow up on my previous inquiry from last Tuesday regarding prospective PhD student openings in your laboratory for Fall 2026.
8

9
I know your schedule must be incredibly demanding, and I completely understand if you have not had an opportunity to review my materials amidst your busy semester priorities. For your convenience, I have left my academic CV and preprint attached below.
10

11
If your schedule permits a brief conversation over the coming weeks, I would be deeply honored to connect. Regardless, I truly appreciate your ongoing contributions to the field of geometric deep learning and thank you for your time.
