Kalani Hettiarachchilage

Doctoral Lecturer

Kalani Hetti specializes in condensed matter physics, in particular the origin of exotic quantum phases that show complex interesting nontrivial states. Further, she uses computational methods based on density functional theory to calculate materials’ electronic, magnetic and phonon properties and predict new material with exceptional physical properties. She loves to teach and inspire her students in science. Her focus is to educate students by planning and implementing new teaching methodologies to promote interdisciplinary education among physics and science classes by creating a connection to physics educational research.


Before joining the College of Staten Island faculty, Kalani Hetti held a postdoctoral position at the Center for Computational Technology and Physics at Louisiana State University.  She also worked as temporary full-time physics faculty at the College of New Jersey and at Seton Hall University.


PhD, Louisiana State University, USA

MS, Norwegian University of Science & Technology, Norway
