and attended
DeWitt Clinton High School where his physics teacher Daniel Kaplan inspired him to study physics.
Alexander is a scientist and a jazz saxophonist who ponders links, including sound, between small and big things in the universe that go beyond Einstein's curved space-time and big bang theory.
Einstein's field equation
In the general theory of relativity, the Einstein field equations (EFE; also known as Einstein's equations) relate the geometry of spacetime to the distribution of matter within it.
The equations were published by Einstein in 1915 in the fo ...
being his favorite equation, his publication ''The Jazz of Physics'' is an autobiographical reflection of his research and theories. Involved with cosmology as a professional physicist, he is also a jazz saxophonist and a student of the works of John Coltrane, among other musicians interested in cosmology. At DeWitt Clinton High School in 10th grade, Alexander's mentor was his physics teacher Daniel Kaplan, who was the reason behind diverting Alexander's mind towards physics when discussing velocity and friction. In 2006, Alexander was named as one of the eight ''National Geographic'' inquisitive experimenters and explorers.

before joining the faculty at Brown University. Alexander is the president of the
National Society of Black Physicists. He is also the executive director of Science and Arts Engagement New York Inc. (SAENY).
Academic life
Alexander started his academic career as a postdoctoral researcher at Imperial College, London, (2000-2002) and later on went to be a postdoctoral researcher at Stanford University's SLAC and Institute for Theoretical Physics (2002-2005). In 2005, he became an assistant professor of physics at Penn State University. In 2008, he served at Haverford College as an associate professor of physics leading to his positions of Ernest Everett 1907 Associate Professor of Natural Sciences and associate professor of physics and astronomy at Dartmouth College.
Alexander also works as a professor at Brown University and has spent much of his career as a first generation advocate. He also advocates for historically under-represented groups in the sciences.
He is a member of the
editorial board of
''Universe''.

Research
In June 2012, Alexander co-authored a paper that reinterpreted
Hořava–Lifshitz gravity. The paper, ''Hořava-Lifshitz theory as a fermionic aether in Ashtekar gravity'' described how the ''HL theory'' could be naturally occurring. The authors also theorized that ''HL gravity'' could be interpreted as a time-like current that fills space-time.
In December 2012, Alexander was the co-author of the paper "Gravitational origin of the weak interaction's chirality".
Focusing on the
Lorentz group, the authors studied the unification of the electroweak and gravitational interactions and the space-time connection. The authors theorized, in ways similar to
Plebanski and
Ashtekar, how those weak interactions on the right-handed chiral half in space-time connection could explain the
weak interaction.
The theory devised by Alexander and his co-authors was broken down into two phases. The first is a
parity
Parity may refer to:
* Parity (computing)
** Parity bit in computing, sets the parity of data for the purpose of error detection
** Parity flag in computing, indicates if the number of set bits is odd or even in the binary representation of the r ...
symmetric phase, similar to the studies and workings of Speziale. The next phase depends on whether the parity is broken or not. Under the breaking, it shows a
Dirac fermion expressing itself as a chiral neutrino.

Around the same time, Alexander co-authored another paper that focused on the study of electric time in
quantum cosmology. The paper formulated and studied new possibilities of the
quantum behavior of space-time.
Alexander has mainly worked to extend Einstein's
general theory of relativity curved space-time, taking it to extremes in the connection between the smallest and largest entities in the universe.
