About

I am passionate about biomedical research and enjoy the intellectual challenge behind it. Since completing graduate school, I have worked exclusively in research departments in various Medical Centers. I want to use my knowledge and skills to assist scientific studies, and in the long run, bring benefits to human lives. I have been working as a lab technician/senior research assistant/lab manager in different research labs, and thus have developed extensive experience in design, develop, perform various experimental procedures and finishing the data analysis. I am able to troubleshoot problems seamlessly and maintain the highest degree of work ethic. My other responsibility is IACUC animal protocols composition/coordination. Besides, I have been assigned a great deal of lab management duties that have given me the opportunity to develop outstanding interpersonal communication skills. I am reliable and enthusiastic to work with people to overcome problems. I am always willing to offer assistance, and is able to follow through to ensure that the work gets done well.
