NDUB Takes the Global Scientific Stage at ISBS 2026!

Notre Dame University Bangladesh (NDUB) proudly marked another milestone in its growing international research presence as Dr. Muntasirul Hoq, Assistant Professor, Department of Microbiology, was invited to speak at the 20th International Symposium on Blood Substitutes (ISBS 2026) in Xi’an, China (September 12–14).

On September 13, Dr. Hoq presented his research titled:

“Polyhemoglobin with Synthetic Enzymes: Functional Replacement of Catalase, Superoxide Dismutase, and Carbonic Anhydrase in Warm-Ischemia Cell Models.”

The research, originating from his PhD work at McGill University, Canada, explores a next-generation polyhemoglobin system incorporating synthetic enzyme mimics to protect cells during warm ischemia.

ISBS 2026 brought together leading scientists, clinicians, engineers, biotechnology experts, and researchers from around the world working in artificial cells, blood substitutes, oxygen therapeutics, nanobiotechnology, and transfusion medicine.

Beyond the scientific presentation, the event created valuable opportunities for international collaboration, joint research, technology exchange, student involvement, and future co-authored publications for NDUB.

đŸ‡Ŧ🇧 The journey continues—with ISBS 2028 announced to be hosted by the University of Essex, UK. Dr. Hoq looks forward to bringing new research initiatives and student-led projects from NDUB to future international scientific platforms.

From Bangladesh to the world—NDUB’s research journey continues.

🏆 Proud Achievement for NDUB Microbiology! đŸĻ đŸŒ

We are delighted to share that Shanin Alam Goongoon, a student of MICR-3, Department of Microbiology, Notre Dame University Bangladesh (NDUB), has secured 3rd Position in the “Science in Slides” segment of the 2nd Bangladesh Science Exposium 2026, organized by the Dhaka University Science Society (DUSS).
📌 Presentation Topic:
“Climate Change: Adaptation vs Mitigation — What Should Science Focus On?”
In her presentation, Shanin explored the important relationship between microorganisms and climate change, highlighting how microorganisms influence climate processes and how microbiological knowledge and innovation can contribute to both climate-change mitigation and adaptation.
The presentation was held on 1 August 2026, and she was officially awarded her 3rd Position prize on 15 September 2026. đŸŽ–ī¸
She also participated in the “Science in Poster” segment with the thought-provoking topic:
đŸ§Ŧ “Designer Babies — The Ethics of Editing Humanity”
Her participation in both segments reflects the growing enthusiasm of our students toward scientific communication, interdisciplinary research, and addressing global challenges through microbiology and science.
👏 Congratulations, Shanin!

A Heartfelt Farewell to Our Honorable Vice Chancellor Dr. Father Patrick Daniel Gaffney, CSC
The faculty members and students of the Department of Microbiology, Notre Dame University Bangladesh (NDUB) had the privilege of presenting a small token of love and appreciation to our honorable Vice Chancellor Dr. Father Patrick Daniel Gaffney, CSC on the occasion of his farewell as he prepares to leave for the USA.
Throughout his tenure, Father has made significant contributions to the development and smooth functioning of our Department and also the other Departments of NDUB as well. He served for about 10 years at NDUB. His constant support, encouragement, and guidance have always inspired us and strengthened our academic community.
We are truly grateful for his invaluable contributions and the kindness he has shown toward the Department of Microbiology and its students.
As you begin this new chapter in the USA, we wish you good health, happiness, success, and a wonderful journey ahead. Your support and contributions will always be remembered by us.

Farewell, Father, and thank you for everything! â¤ī¸
