To visit Dr. Hasi Personal website Click Here.She is a theoretical physicist and an expert in studying the collision of positron and positronium (Ps) with atom at low and intermediate energies. She introduced the Coulomb-Born and Coulomb-Born-Oppenheimer approximation methodogy to study ionization processes in Ps and atom scattering. Her present interest lies on cold-atomic interactions and many positroniumic molecule/dimer etc. She has a good interests in theory of tides, gravitational waves and is actively participating the project. She is highly enthusiastic to learn the neural networks and DNA computing. She is also interested in positron emission tomography (PET). She is very happy to visit the laboratories and enjoys the association of all the UCR people including the graduate students. She gratefully acknowledges the very caring and encouraging attitude of Prof. Mills and his association. She appreciate the close association of Matt Gonzales & Louis Bran, B.S.Physics students to draw her attention in classical mechanics problems. She enjoys the close company of little Walter (Walter Javier Marcantonio Mills), a high school student who just learned to prepare gel in bio-science laboratory and who does not like Physics or Mathematics. She is also very thankful to SERC, DST, Govt. of India and NITTTR, Kolkate for permitting her visit.
