V. Sahni, Quantal Density Functional Theory, 2nd Edition, Springer-Verlag, Berlin/Heidelberg 2016.
This book is on quantal density functional theory (QDFT) which is a time-dependent local effective potential theory of the electronic structure of matter, both natural and 'artificial'. The time-independent QDFT constitutes a special case. The 2nd edition describes the further development of the theory, and extends it to include the presence of an external magnetostatic field.

Quantal Density Functional Theory. Berlin and Heidelberg, Germany: Springer-Verlag. The book, aimed at advanced undergraduate students, graduate students and researchers in the field, encompasses the critical ideas developed in my research over the past two decades. The book describes a new theory of electronic structure incorporating both time-dependent and time-independent phenomenon. It further provides an entirely new perspective on both time-dependent and time-independent Schrödinger and Hohenberg-Kohn-Sham Density Functional Theories.

Professional Leadership
Director, Coordinated Engineering and Engineering Honors Program, 1988-present. The program constitutes the first two years of the baccalaureate degree awarded in the fields of chemical, civil, computer, electrical, environmental and mechanical engineering. A carefully articulated coordination with the engineering schools of Polytechnic University, City College and the College of Staten Island guarantees transfer to these institutions into the junior year. (Students also transferred to MIT, SUNY Stony Brook, University of Wisconsin, Cooper Union, Michigan State University, Purdue University and the University of California). In 2002, the engineering program was incorporated into the Honors Academy of Brooklyn College as the Engineering Honors Program. My responsibilities include orientation, advising, recruitment, open houses, financial aid and transfer officers to meet with our students, and to renegotiate the articulation as changes in engineering education occur.
