Paritosh Kumar Biswas earned Doctor of Veterinary Medicine (DVM) degree (1990) from the Bangladesh Agricultural University, Mymensingh, Bangladesh and PhD degree (1995) from the St. Petersburg State Academy of Veterinary Medicine, St. Petersburg, Russia. He also received a Diploma in Poultry Diseases and Diagnostic Methods (2006) from the Royal Veterinary and Agriculture University (currently, integrated with the Copenhagen University), Copenhagen, Denmark and Six month-long intensive training on Molecular Microbiology from the Copenhagen University, Denmark (2010-11).

He started his professional career as a Veterinary Assistant Surgeon (1995-96) under the Department of Livestock Services (DLS), Bangladesh, then served as the Livestock Specialist in Ansar-VDP Unnayan Bank (1996 -98), a specialized Bank in Bangladesh from which he joined the Department of Microbiology, the then Chittagong Government Veterinary College (currently, CVASU, from 7 August 2006) in 1998 and served as an Associate Professor until 2003. Since then he has been working as a Professor in the Department of Microbiology and Veterinary Public Health, except for 8 months in 2008 - 2009 when he served as a National Consultant (Highly Pathogenic Avian Influenza (HPAI) outbreak response and training, Bangladesh) at FAO, Bangladesh. As part of additional responsibilities he also held some other academic positions: Head of the Department of Microbiology (1998 – 2006, 2011-13), Coordinator in Bangladesh for the Commonwealth-funded Distance Learning Partnership Project on Commonwealth Scholarship with Master of Science degree courses in the areas: Livestock Health and Production, Veterinary Epidemiology and Public Health at the Royal Veterinary College, London, UK (2011-13); Dean, Faculty of Food Science and Technology, CVASU (2013-15); Executive Editor, Bangladesh Journal of Veterinary and Animal Sciences (2012-14). Currently (from 2015), he holds two additional positions: Director (in-charge), Poultry Research and Training Centre and Director (additional charge), One Health Institute, CVASU.

His research interests include poultry diseases, zoonoses and zoonotic diseases, epidemiology and antimicrobial resistance of zoonotic pathogens.

As the principal investigator Dr. Biswas successfully completed nine research projects financed by different national and international agencies and was/is also involved with three other projects as a co-investigator/team member. He has published 30 papers so far in internationally reputed journals including Emerging Infectious Diseases, PLoS ONE, Epidemiology and Infections, Transboundary and Emerging Diseases, Avian Pathology, Preventive Veterinary Medicine, Veterinary Record, Vaccine, Veterinary Microbiology, Frontiers in Microbiology, Genome Announcements, Rev. Sci. Tech. OIE, Outlook on Agriculture and Livestock Research for Rural Development. He has also published 23 papers in National or Regional journals (see all published credentials as listed below).
