I test and program lighting, ranged from circuit issues to using the Element light board. in addition to this, I communicate with performers and stage crew to ensure timing for cues and changes.Utilized my quick decision making skills to quickly make effective decisions towards situations that arised

Ensured that students learning about logic design got the foundation they needed in order to succeed.

Held various mentorship roles that varied from onboarding students, to helping launch a new projectNeptune – Globablly Accessible Microfluidic Design Tool (June 2016) Part of an iGEM summer project, Neptune aims to make microfluidics globally accessible by offering an intuitive platform to design and build continuous flow systems with the end goal being to produce customized, parametric blueprints of their microfluidic setup. o Developing Sensor Array to be used in our Microfluidic flow to record and ultimately visualize experimento Responsible for choosing NodeJS as the platform to develop with so that we could encompass Serial Communication, Cross-Platform Compatibility, and Portability.o Participating in iGEM Giant Jamboree in October 2016 to compete with other iGEM teams.http://blog.bantamtools.com/neptune-custom-accessible-microfluidicshttp://2016.igem.org/Team:BostonU_HWPhagebook – Creating a Software Environment for Social Synthetic Biology (2015) Worked with existing Clotho 3.0 software to create a Java web application to create a social networking interface incorporating lab inventory management and projects/personnel networking. Functionalities include a secure email verification system that uses salt and hashing methods. Used Cookies, Ajax, JavaScript, Jetty, Maven, GitHub, HTML, and CSS to create an ordering portal.o Received Undergraduate Research Opportunities Program Award for work on Phagebook.Presented work at the International Workshop on Biodesign Automation (IWBDA) in New Castle, England on August 16th, 2016
