    Kidnetix Baton Corp is a not-for-profit organization gives young athletes between the ages of 2-23 the opportunity to learn and experience the sport of baton twirling. Kidnetix has always had a special place in my heart. I was a member since I was 4 years old. My leadership, determination, hard-work, and passion for the sport of baton twirling allowed me to transition into a student instructor role while I completed high school. I taught students proper technique, the importance of teamwork, and guided the young athletes to build a positive, headstrong mindset. After moving away to college I wanted to share the life skills I learned in the twirling community with future baton twirlers. I currently instruct, choreograph, and design visuals for twirlers ranging from 6 - 19 whom compete at regional, Atlantic Coast and International championship competitions during the winter months. My goal is to push the envelope in the sport of twirling and capitalize on each twirler's talent. Furthermore, I direct my efforts to capture the artistic value and originality of the piece I arrange for the athletes through visual aids including props, floor designs, costume design, and movement design.Skills:- Leadership/ Director Role- Critical Thinking- Team Building- Communication- Artistic Execution- Adaptability

    Project Title: Study of the Effect of Welding Parameters on the Elastic Properties of ASTM A131 Steel Using Scanning Acoustic MicroscopyBrief Description:ASTM A131 steels are commonly fabricated by welding for structural and industrial applications. Fluctuating temperatures near weld zones introduce residual stresses which may result in internal cracking. Thus, nondestructive testing (NDT) is often used to qualify parts to be used in operating conditions. This study investigated how surface acoustic wave (SAW) velocity generated by scanning acoustic microscopy (SAM) could be used to predict material properties near the heat affected zone which were processed with various parameters.Skills:- Investigated the use of ultrasonics to characterize material properties and discontunuities- Performed material preparation using metallographic techniques - Analyzed microstructure using optical microscopy and scanning electron microscopy- Used Matlab to perform Fourier Transforms on V(z) curves generated by SAM to collect SAW velocity measurements - Performed Vickers hardness measurements to compare with SAW velocity to determine Young's modulus of the weld regions of the steel
