Experience

Research intern at NYU minimally invasive surgery lab

July 2011 – January 2013

• Design and analysis of Desktop Knee testing machine for evaluation of kinematic

characteristics of artificial knee joints

The CAD models of the two prototypes of the testing machine were created using Solidworks

2013 and the CAD models of artificial knee joint samples designed in rhino were installed in

both the prototypes as per requirement and then using Motion Analysis tool in Solidworks 2013,

the displacements of points of contact between Femur and Tibia were determined and used to

analyze overall laxities.

• Researched in bone density patterns in proximal tibia in relation to implant design using

'MIMICS' software and MATLAB scripts.

In relation to Unicompartmental orthopedic knee replacement design, CT scans were used and

processed in MIMICS software to produce solid models of proximal tibia which showed the 3-D

shape and densities color maps throughout the solid. Later on the densities and areas of

horizontal sections spaced 1mm apart up to 20mm depth for proximal tibia were imported from

MIMICS and processed in MATLAB software to draw plots of average masses and average

cumulative masses for full sections and for one third of sections (medial side) with respect to

depth.

MATLAB/SIMULINK

October 2012 to December 2012

• Developed equations for linear control of mechanical system designed a full-order observer and

Investigated the observer performance by providing simulation plots for the observer error

e(t)=x(t)-xe(t).

• Obtained closed-loop system’s state response by using state estimates for feedback and

Compared the responses for open-loop, full-state feedback closed-loop, and observer-based

feedback closed-loop.

Designed control system for rotary inverted pendulam

September 2012 to December 2012

the control design using Matlab and Compared simulation responses for the open-loop and

closed-loop cases.

• Developed an augmented state-space model to address the problem of stabilizing the rotary

inverted pendulum while allowing the arm position to track a desired set point and designed a

full state feedback controller using Matlab.

Mechatronics

September 2012 to December 2012

• Experienced with Basic stamp 2 microcontroller and built a smart mousetrap that uses IR

emitter and an IR detector to detect the rat and send signal to servomotor which closes the trap

door.
