Dr. Katakam Sivaprasad was born in 1977. He completed his Diploma in Metallurgical Engineering at Government Polytechnic, Visakhapatnam, Andhra Pradesh, India. Later, he completed his AMIIM (Under Graduation) and moved to the Indian Institute of Technology Madras, Chennai, India to complete his M.Tech. (2002) and Ph.D. (2007) in Metallurgical Engineering. He took his professional career in 2007 at the National Institute of Technology (NIT), Tiruchirappalli, Tamil Nadu, India as an Assistant Professor in the Department of Metallurgical and Materials Engineering. He served in administrative roles like Associate Dean (Research & Consultancy) at NIT. Presently, he is working there only as a Professor (Full). His major activities at NIT are teaching and research related to mechanical behavior of materials, structure–property–process correlations, additive manufacturing, and materials characterization. His major research activities are on cryo‑deformation of materials, metal‑intermetallic laminates for defense applications, deformation of nanocrystalline materials, and additive manufacturing. He has published more than 110 research articles in refereed international journals and presented his work in more than 50 conferences. He edited few special issues in SCOPUS and SCIE journals. He has contributed to few book chapters in refereed edited books. He has guided 13 doctoral candidates and more than 50 Master’s candidates at NIT. He completed many sponsored and consultancy research activities with various funding agencies such as Department of Science and Technology (India) (DST), Ministry of Higher Education (MoHE), Defence Research and Development Organisation (India) (DRDO), Naval Research Board (under DRDO, India) (NRB), Indian Space Research Organisation (ISRO), and Tata Steel. He organized several international and national conferences related to advanced materials and additive manufacturing. He has a very strong international collaboration from various countries such as USA, UK, Japan, Estonia, and Singapore, and he was a visiting scientist to the USA and Japan. He is the first recipient of Sir Dorabji Tata and T R Anantharaman faculty fellowship in 2014 and received many best paper awards in many conferences. He is on many international research review panels across the globe. He is a senior member of Society of Manufacturing Engineers –Hong Kong (SMEHK) and also a life member of Indian Institute of Metals (IIM), Indian Welding Society (IWS), Materials Research Society of India (MRSI), Indian Society for Technical Education (ISTE), Powder Metallurgy Association of India (PMAI), and Indian Science Congress Association (ISCA).

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
