research experience
Graduate Research Assistant, Aug 2021-Present
Paul M. Rady Mechanical Engineering
University of Colorado Boulder, CO, USA
- Developed an electronic skin (e-skin) technology and implemented a Human-
Machine Interface (HMI) pressure monitoring system for knee prostheses,
targeting transtibial and transfemoral amputation patients. The system enables real-
time visualization of pressure distribution to monitor the pain caused by
prosthetic wear. (In collaboration with Quorum Prosthetics & Rocky Tech). - Conducted Finite Element Analysis (FEA) to investigate the mechanical behavior of
wearable biomedical devices.
– Optimized the design of Stretchable micro-Needle Adhesive Patches
(SNAP), achieving a 60% reduction in pain during the use of SNAP device for
extended hours; co-authored the peerreviewed publication, published in
Science Advances (link).
– Performed structural analysis of wearable Thermoelectric Generators (TEGs)
and Transparent Stretchable Organic LEDs (TSOLEDs) to enhance their
performance and structural integrity; manuscript currently under
preparation.
research assistant, Mar 2018-Jul 2021
SUTD-MIT International Design Centre (IDC)
Singapore University of Technology and Design, Singapore
- Led the end-to-end design, optimization, and fabrication of next-generation
composite structures using additive manufacturing, leveraging innovative bio-
composite materials to improve mechanical strength and promote
environmental sustainability. - Engineered a novel hygroscopic and superabsorbent polymer, seamlessly
integrated with knitted textile architectures to create smart, responsive kinematic
structures capable of passive actuation in dynamic environments. - Authored 8 research publications — including 3 journal articles and 5
international conference papers — showcasing advancements in sustainable
materials and adaptive systems.
Graduate research assistant, Aug 2015-Nov 2016
Singapore centre for 3D printing (SC3DP)
Nanyang technological University, Singapore
- Designed, fabricated, and analyzed the mechanics of 3D-printed cellular
structures using advanced geometries and material gradients, including 2D
prismatic (honeycomb) and 3D lattice (icosahedron, Kagome, corrugated)
configurations, to enhance mechanical performance.
– Performed in-depth structural analysis to investigate deformation
mechanisms and failure behaviors of 3D-printed structures, led to design
optimization.
– Authored 2 research papers on the design and performance of these advanced
cellular structures, contributing to the field’s understanding of additive
manufacturing.
