Nazmul Hosen, a graduate student in the USM Department of Chemistry, exemplifies passion and dedication in his pursuit of scientific discovery. With a focus on interdisciplinary chemistry involving inorganic and analytical chemistry, Hosen’s journey highlights his impactful contributions to science and his inspiring academic story.
As an interdisciplinary graduate student at USM, Hosen has immersed himself in multiple projects that bridge different fields of chemistry. His research focuses on designing and synthesizing molecular sensors for detecting toxic chemicals of interest. A significant part of his work centers on developing sensors to identify chemical warfare agents—poisonous chemicals that pose significant threats to human safety and are often used in wars. In Dr. Karl Wallace’s lab, Hosen synthesizes molecules. To broaden the scope of his work, Hosen collaborates with Dr. Wujian Miao’s lab, where he applies electrochemical techniques to test the properties of his molecules. Combining these with optical sensing techniques in Dr. Wallace’s lab, he tackles fundamental challenges in sensor development. His efforts are not only advancing the field but are also leading to the completion of a manuscript, which is soon to be submitted for publication.
Hosen’s research extends beyond the lab, addressing national and global concerns. One of his projects, funded by the US Department of Defense, focuses on detecting hazardous chemicals that could kill thousands of people within minutes. Accurate detection of such substances is critical for eliminating potential threats and ensuring public safety. Hosen shared a historical example of the devastating impact of chemical attacks, such as the 1995 incident in Japan, where a lack of detection tools led to numerous casualties. He envisions his sensors being portable and user-friendly, enabling first responders to quickly identify and mitigate threats, ultimately saving lives.
Hosen’s academic journey began in Bangladesh, where he completed his undergraduate degree and worked as a teacher. His passion for returning to the classroom and engaging in research inspired him to apply to Southern Miss. Upon joining, Hosen explored different labs before finding his niche in Dr. Wallace’s and Dr. Miao’s collaborative research groups. Reflecting on his experiences, Nazmul credits his teachers, colleagues, and mentors for shaping his path and giving him the confidence to pursue ambitious goals.
When asked about his experience in graduate school, Hosen admitted to moments of uncertainty.
"At the beginning, I was excited, and in the middle, I was not sure what I was doing," he shared. "But now I think it was worth it completely."
His journey taught him resilience, confidence, and the strategies needed to excel in his field. Meeting inspiring people along the way has also enriched his experience and reaffirmed his decision to pursue this path.
His advisors also echo his thoughts.
“Nazmul has significantly improved over time,” Wallace claimed. “When he first started his Ph. D., he was nowhere near where he is now and he really is working hard on his research.”
“Nazmul has definitely been putting in more time and effort than I have seen him do before,” Miao said. “His growth has been very obvious to us.”
Hosen’s advice to undergraduates and prospective graduate students is rooted in wisdom and personal experience.
"Things don’t get easier; instead, we learn more efficient ways to handle them," he remarked.
He encourages students to start exploring their passions early, remain open to trying new fields, and never feel it is too late to make meaningful changes.
"Find your passion, and don’t wait to begin," he advises, emphasizing the importance of proactive learning and adaptability.
Looking ahead, Hosen sees sensor design and synthesis as a burgeoning area of research with limitless possibilities. Developing sensors that combine high sensitivity, selectivity, portability, and ease of use remains a critical challenge in the scientific community. Nazmul’s work positions him at the forefront of this exciting field, contributing innovative solutions to pressing global issues.
Hosen’s journey exemplifies the spirit of determination and curiosity that drives scientific progress. His contributions to environmental and analytical chemistry reflect his commitment to making a positive impact, both within the lab and beyond. He stands as an inspiration to his peers and aspiring scientists, showcasing the rewards of perseverance and passion in research.
