Work Experience

Research Associate and Lab Manager at Trenchless Technology Center (TTC)

Department of Civil Engineering, Louisiana Tech University, Ruston,

LA (Sep 2009 - Present)

As a research associate my responsibilities are

. To study the electrical properties of conductive filler reinforced

geopolymer cement for EMI (electromagnetic interference) shielding

wall panels and ESD (electro static discharge) flooring applications.

. To study the rheological properties of fly ash based geopolymer cement

for its extrudability and to develop commercial applications from it.

. To study the cyclic thermal and pressure loading effects on the

frictional forces at the pipe-grout interface of a fusible PVC pipe

used in slip lining application (project objectives accomplished).

. To assist the supervisor in writing proposals and acquiring funding

for the projects at TTC.

As a lab manager my responsibilities are

. To monitor and schedule student and technical staff hours

. To give guidance to undergraduate and graduate students on their

research projects

. To serve as a point of contact between the external entities and

the lab

. To oversee all the projects at TTC

. To keep track of lab supplies and place the orders for required

material

Research Assistant at Trenchless Technology Center

Department of Civil Engineering, Louisiana Tech University, Ruston,

LA (Mar 2005 - Aug 2009)

As a graduate research assistant I've worked on the following projects

. Electrokinetically induced protective coating for concrete sewer pipes

against biological induced corrosion. Under the influence of a weak

electric field antimicrobial agent was driven into the pores of

concrete to attain resistance against biological corrosion. Atomic

Absorption spectroscopy tests were performed on the electrokinetically

coated samples to confirm the presence of antimicrobial agent.

. Smart materials for construction and structural health monitoring of

civil infrastructure. Carbon fibers were added to the fly ash based

geopolymer cement to induce electrical conductivity in the

cementitious binder. AC impedance spectroscopy analyses were performed

on the sample specimens to quantify the electrical conductivity

property. Dynamic loading of the conductive specimens revealed that

the changes in electrical resistivity were related to the state of

stress in the sample specimens. Experimental study showed that by

monitoring the changes in electrical resistance of a conductive

structural member, its health could be monitored.

. Material characterization and testing of a structural liner used in

sewer rehab applications. The liner was subjected to different

chemical solutions that are typically found in a sewer atmosphere

(Pickle Jar Test - L.A. Green Book). Its strength was evaluated by

performing standard tensile (ASTM D 638) and hardness tests (ASTM D

2240) on the sample specimens before and after subjecting to chemical

solutions. Third party testing of protective sewer liner.

. Improving the mechanical strength of a low viscosity cementitious

grout. Four different fiber types were added to a cementitious grout

without affecting its flow and viscosity properties. Standard flexure

(ASTM C 580) and tensile tests (ASTM C 307) were performed on the

grout sample specimens to evaluate the changes in strength by to the

addition of fibers. Third party testing of commercial cementitious

grout used in GIPP application.
