WORK EXPERIENCE:
••••• RESEARCH ASSISTANT Aug ••••• - Present
COMPUTER SIMULATIONS OF AMORPHOUS ZnO BASED OPTICAL MICRORING RESONATOR SENSORS FOR BIOLOGICAL AND GASEOUS SENSING
Ohio University, Current project. My role: Material selection, designing and simulating. Team size: 2
Designed amorphous- ZnO based optical microring resonators for chemical and biological sensors.
The microring resonator is a single mode, vertically coupled resonator. The design of the single mode resonator is done analytically using Marcitili method and verified with Finite Element Method (FEM).
Surface and homogenous sensing schemes are discussed and their dependence on waveguide physical parameters is simulated numerically using FEM and Finite difference time domine modeling (FDTD).
ZnO LOW OPTICAL OVERLAP MODE (LOOM) EVANESCENT WAVE CHEMICAL SENSOR
- Ohio University, current project. My Role: Simulations using FEMSim (RSoft). Team Size: 3
Designed ultra thin membranes of a-ZnO and a-SiC to form a LOOM using FEM.
Shorter wavelengths are used, to achieve high sensitivity and low optical transmission losses.
TRAFFIC LIGHT CONTROL IN A HIGHWAY-COUNTY ROAD INTERSECTION (Spartan II) using XILINX ISE ••••• - VHDL (MS: course work), Ohio University, Athens, Team size: 1 Fall •••••
Designed a FPGA design of a traffic light controller using Spartan2 kit
The design was based on Finite state machine logic of VHDL.
The designed code was tested in Active HDL and implemented using Xilinx ISE ••••• on a Spartan 2 kit
The implementation was done for a highway-county road junction where the signal turns green for the county road only when the sensor is turned on. Pedestrian crossing request was also implemented.

••••• INTERNSHIP in CVRDE (R&D org•••••Govt. of India), Chennai, India. Jan ••••• - Aug •••••
TESTING AND EVALUATION OF PMSM WITH POWER CONDITIONING Team size: •••••
Tested and evaluated the performance of a Permanent Magnet Synchronous Machine (PMSM), used as windmill generator, with power conditioning (inverter, battery, buck-converter).
A simple data acquisition system was designed using a power conditioning circuit (analog) and Labview.

PROJECTS:
