Dear Prof. Mei Chen, I hope this message finds you well. My name is Ayesha Rahman, and I am currently a graduate student at BUET, Dhaka, Bangladesh. I am writing to express my strong interest in joining your research group at CSAIL, MIT as a prospective PhD Student. I am particularly interested in your work on network security, blockchain systems, and adversarial machine learning and would value the opportunity to learn more about your current projects. In my role as Research Assistant at BUET Network Security Lab, I developed intrusion detection models for enterprise networks and evaluated adversarial robustness on real traffic traces. I have 4 publications, including 2 journal articles. My background includes the Dean's List honor and IEEE student branch leadership award, with industry experience at Cisco. My relevant technical skills include Python, PyTorch, Wireshark, and network protocol analysis. I would appreciate the opportunity to discuss potential PhD Student positions in your group. I have attached my CV, transcript, IELTS score report, and GRE score report for your review. I am happy to share any additional materials at your convenience. I would be glad to have a conversation to discuss my projects and research interests further. Thank you for your time and consideration. I look forward to hearing from you. Best regards, Ayesha Rahman
