I recently completed my Ph.D. (August 2024) at the National Institute of Technology
Srinagar, India, in collaboration with the Indian Institute of Technology Ropar, India. Prior to
this, I earned a Master of Technology in Machine Design from Mumbai University, Bombay,
India, in 2017. My doctoral research focused on both computational and experimental
approaches to CAD based & bio-inspired design and 3D printing, specifically in polymer
printing, biomaterials development, mechanical & CFD simulation and bioprinting, using
composite biomaterials based on silk fibroin & bovine bone p[article, and biodegradable
polymers. The aim was to create foams and scaffolds for in vitro and in vivo studies related to
tissue engineering and shock absorption in biomedical implants.
During my research, I designed novel strut-based lattices, triply periodic minimal surface
(TPMS) structures, biomimetic seashell structures, and bio-inspired bovine bone structures.
Additionally, I developed 3D-printed scaffolds composed of composite biomaterials such as
silk fibroin, bovine bone, polycaprolactone (PCL), and chitosan. My Master’s research also
involved AI-driven vibration analysis for mechanical system diagnostics.
I have utilized various mechanical characterization techniques—including uniaxial testing at
different strain rates, dynamic mechanical analysis, high strain rate testing, cyclic testing, and
Vickers hardness testing—to evaluate the mechanical properties of 3D-printed structures for
bone tissue engineering and implant development. Moreover, I have experience with imaging
techniques such as micro-CT, histology, FESEM, and AFM, along with image processing
software like ScanIP, Avizo, and Digital Image Correlation (DIC). Additionally, I have
employed Fourier Transform Infrared (FTIR) spectroscopy, thermogravimetric analysis
(TGA), and X-ray diffraction (XRD) to analyse biomaterial composition and thermal
behaviour. I have designed, fabricated, and validated a Split Hopkinson Pressure Bar (SHPB)
setup for high strain rate testing of implant structures, simulating loading conditions
associated with trauma and accidents. This involved gaining expertise in mechanical design,
manufacturing, sensor calibration, data acquisition system interfacing, and graphical interface
development for data acquisition. Beyond experimental research, I have extensive experience
with computational modeling, particularly using Finite Element Analysis (FEA) in Abaqus,
with custom user subroutines (UMAT, VUMAT) for modeling implant damage and
viscoelastic responses at varying strain rates.
During my Ph.D., I authored 12 research articles, seven review articles, and one book chapter
as the first author. Many of these are published, while others are under review or prepared for
submission (detailed in my CV). Additionally, I co-authored a paper contributing to the
mechanical and microstructural analysis of biological and bioinspired materials.
Through my research journey, I have gained expertise in CAD modeling, MATLAB-based
design, medical image-based design (DICOM and CT-scan files), biomaterial fabrication, 3D
