I am writing to provide my strong recommendation for Bohan Chen's admission to your doctoral program in Environmental Engineering. As a full professor in the School of Civil and Environmental Engineering at Harbin Institute of Technology, Shenzhen, I have worked with Bohan as his mentor since September 2020 and have had the pleasure of getting to know him in both academic and personal settings.

Bohan is the most hardworking master student I have ever mentored. He consistently spent long hours in the lab, conducting experiments and analyzing data to ensure accurate results. In the class Environmental Organic Chemistry I taught, Bohan demonstrated an assiduous attitude and ultimately earned an A (top 20%) in this course. In another class I taught, Environmental Engineering Special Subject, he achieved an A+ (top 10%).

Bohan has demonstrated a remarkable capacity for independent thinking and self-motivation. His master's thesis focuses on enhanced biological phosphate removal in secondary effluent treatment. He devoted a significant amount of time and effort to his research and made several innovations in this process. He successfully achieved the goal of his thesis, and his research results will be published in the near future. His strong execution, curiosity, and critical thinking in research highlight his potential as a researcher.

Bohan is also a reliable student. He actively collaborates with his colleagues and contributes valuable insights during group discussions. He is willing to help other colleagues in their research, so he has also become a co-author on articles published by other colleagues. I have no doubt that he will continue to grow as he pursues his academic and professional goals.

Overall, Bohan is an exceptional student with a deep passion for research, strong analytical skills, and a committed work ethic. I believe that he will become an excellent researcher in the future. I wholeheartedly recommend Bohan Chen for admission to your doctoral program at your school.
