I am an Assistant Professor at Texas State University (TXST). Before joining TXST, I was a postdoctoral scholar at Lawrence Livermore National Laboratory (2013-2017). Broadly, I am interested in leveraging data science methodologies to address challenging questions that pertain to extreme-scale computing environments. My research spans fault-tolerance, performance modeling, prediction, and reproducibility for large-scale applications. I earned my Ph.D. in Electrical and Computer Engineering from Purdue University, and B.Sc. in Computer Science and Engineering from Bangladesh University of Engineering and Technology. My work enables large-scale simulations, often used in different fields such as bioinformatics, earthquake engineering, material science, to leverage the incredible computational capabilities of modern clusters.

I am the co-founder of Bangladeshi Women in Computer Science and Engineering (BWCSE) -- research and mentoring platform for encouraging female students in Bangladesh to get involved in scholarly activities. Since its inauguration in 2014, this pioneering effort has provided hundreds of female students with information and guidance to apply for national and international opportunities and engaged them in resume-building activities. A list of student scholars who have benefitted from the mentorship and resources provided by BWCSE can be found here.
