Paresh Pujara


Biopharmaceutical Professional



Paresh Pujara


My name is Paresh Pujara and I am a well-rounded Biopharmaceutical professional.

In my academic background, I have specialized in Microbiology, Biotechnology and Biochemistry. In the earlier phase of my academic life, I developed a strong interest into protein chemistry and protein based drugs to cure/prevent life threatening diseases.

Due to my interest in protein based drugs, I started my career as a Research Associate in the R&D facility of a leading Biopharmaceutical company in India where I worked on recombinant human (rHu) biotherapeutic proteins and its derivatives. It was an awesome opportunity for me to explore protein purification technology development, analytical testing method development, formulation development, technology transfer and scale-up. In my subsequent assignment as a Technology Lead, I managed multiple operations on shop floor and accomplished validation and IPR related activities. Currently, I am working as a Bulk Manufacturing Manager in the world leading vaccine manufacturing company in Canada. In my current role, I am a part of the manufacturing team to build a brand new advanced vaccine manufacturing facility for capacity expansion. It is a unique opportunity for me to experience the genesis of cGMP compliant manufacturing facility and all critical milestones associated with it.

With more than nine years of experience, I clearly feel that Biopharmaceutical manufacturing and development is truly a passion of mine. I love what I do and It is my way of contributing towards better healthcare for tomorrow’s world.

In personal life, I am always up for a good book, camera and hiking trails. I am a great admirer of Mahatma Gandhi who very famously said “Be the change that you wish to see in the world”

Characterization of peptide cyclase 1 (PCY1), a serine protease-like enzyme involved in cyclic peptide biosynthesis in plants.

In general, proteins/peptides are linear but surprisingly some proteins/peptides have circular structure. Cyclic peptides are small group of peptides with a circular backbone. A very little was known about the biosynthesis of these peptides in nature. The research project was aimed to decode the molecular mechanism in biosynthetic pathway and characterization of the key enzyme involve in cyclization of procedure.
