PhD student profile: Shuva Bhowmik

Shuva Bhowmik is a PhD candidate within the SJWRI and the Centre for Bioengineering and Nanomedicine, University of Otago. His thesis research is on the utilization of bioactive chitosan for sustainable active and intelligent food packaging, supervised by Associate Professor Azam Ali of the Department of Oral Rehabilitation and Dr Dominic Agyei of the Department of Food Science.

Shuva comes from Bangladesh where he is a faculty member at the Department of Fisheries and Marine Science, Noakhali Science and Technology University (NSTU). He obtained his Master of Science in Fisheries Technology with 1st merit position from Bangladesh Agricultural University, and his Bachelor of Science with Honours in Fisheries with 1st merit position from NSTU.

He is passionate about research on green technology in food packaging, bioactive compounds from the sea, use of biomaterials for the preservation of foods, nutritional components of food, human health risk assessment, and food safety.

What made you decide to do a PhD?

"To be able to conduct research effectively and independently, I wish to develop my research techniques and increase my scientific understanding. In addition, learn about modern research methodologies in active and intelligent food packaging, conduct laboratory experiments, and get knowledge from eminent team members, researchers, and supervisors."

What made you choose the University of Otago for your PhD?

"The University of Otago is ranked in the top 1% of universities in the world, and the natural beauty of Dunedin is outstanding in New Zealand, which makes UoO my desired choice. Additionally, the broad scope of the cutting-edge research, the top-notch laboratory facilities, and the welcoming work environment very impressive."

What are you planning to do after you finish your PhD?

"After receiving my PhD, I plan to continue my research career and conduct additional studies in the fields of active and intelligent food packaging to advance the scientific field, the food and agriculture sector, the biomaterials industry, and international food safety."
