About Me

I spent my undergraduate career in Jakarta, Indonesia, where I obtained a degree in electrical engineering from Trisakti University. I continued my graduate studies at the University of Wisconsin, majoring in physics, electrical engineering, and computer science.

At Widener, I have taught a variety of courses, ranging from introductory programming courses to algorithms, data communications, game programming, computer graphics, and high performance computing (parallel computing). Before coming to Widener, I taught at University of Wisconsin - Madison and University of Wisconsin - Whitewater

Research Interests

My research interests are in the fields of high performance computing, nanoscience and nanotechnology, magnetism, and computational physics. Basically, my passion is to use the computational power to help calculate physics phenomenon on a very small scale (e.g. nanoscale).

  • Professor of Chemical Engineering Sachin Patil and a team of student-researchers published a paper in the journal Computational Biology and Chemistry titled, “Discovery of small-molecule PD-1/PD-L1 antagonists through combined virtual screening and experimental validation.” The paper presented an integrated drug discovery approach leading to identification of a novel PD-1/PD-L1 antagonist that may serve as a starting point for further optimization into potent, small-molecule cancer immunotherapies. The team included students from Widener's chemical engineering and computer science program, as well as Computer Science Professor Jeffrey Rufinus and technician John Stoddart. Michelle DiFrancesco '18, a chemical engineering graduate, served as the student team leader and study first author. She is currently continuing her cancer immunotherapy work at Bristol-Myers Squibb, a leading global biopharmaceutical company.
