Rima Hajjar, a Ph.D. student in Engineering and Plasma Physics, develops numerical simulations and predictive models to describe impurity transport and dynamics of plasmas. In her research, Ms. Hajjar designs algorithms, analyzes "big data," and employs verification tests to compare data to experimentally available results. In recent years, she has studied drive–waves and flow dynamics in plasmas.
"Using statistics and database analysis to improve scientific understandings is the most satisfying aspect of my research."
Ms. Hajjar found an interest in electricity and electronics early in her career, but it wasn't until her master's degree studies in Beirut that a fascination with electromagnetism led her to the field of plasma physics. After earning a master's degree in Computational Physics from American University of Beirut, Ms. Hajjar began studies at UC San Diego to strengthen her research training and gain exposure to scientific culture in the United States. Currently, she holds positions as a Graduate Research Assistant for the Center for Energy Research and a Graduate Teaching Assistant for Mechanical and Aerospace Engineering at UC San Diego. During the summer of 2016, Ms. Hajjar also taught fluid mechanics to pre-college students through UCSD's Academic Connections program.
Ms. Hajjar is a member of the Institute of Electric and Electronics Engineers (IEEE) and American Physical Society (APS). She is also involved with organizations that promote the involvement of women in science and engineering, including the Association of Women in Science and Society of Women Engineers. In 2012, she co-founded UC San Diego's Mechanical and Aerospace Engineering Graduate Women Group and served as Co-President until 2015.
Ms. Hajjar is co-advised by Professor Pat Diamond (CASS, Department of Physics) and Professor George Tynan (Mechanical and Aerospace Engineering, Jacobs School of Engineering).
