 “The intelligence and precision of Science serve the beauty of Art.” – Joseph J. Boutros



I am Professor of Electrical and Computer Engineering at Texas A&M University at Qatar. Previously, I was Associate Professor at Ecole Nationale Superieure des Telecommunications, ENST, Paris, France, a.k.a. Telecom ParisTech.


My main area of expertise is Coding Theory. Here, Coding refers to error-correcting codes, not to the area of programming and developing software. Coding Theory is strongly linked to Information Theory and Digital Communications. For my background in this area, I got my first training as an intern at Philips Research Lab (Laboratoire d'Electronique Philips) in Paris in 1991. I defended my Ph.D. in 1996 on lattices for fading channels, an unusual Ph.D. work which is half way between Mathematics and Electrical Engineering. Later, I was interested in turbo codes, these are parallel Markovian machines good for almost all channels, including the multiple-antenna channel and the multiple-access channel. Also, I designed in 2004-2006 a special turbo code that reaches the highest possible minimum distance (logarithmic in the code length). In the last decade, my research was dedicated to codes on graphs, e.g. root-LDPC codes published in 2010 and to new families of lattices efficiently-decodabe in high dimensions and capable of attaining Shannon capacity at asymptotic dimensions, e.g. LDA and GLD lattices in 2012-2016.


Modern coding deals with codes on graphs and their iterative decoding. The word "codes" stands for both error-correcting codes and lattices. Usual error-correcting codes are vector spaces over finite fields. Lattices are free modules over rings in Euclidean spaces. Since last year, I am also interested in applications of error-correcting codes and lattices in the field of cryptography and machine learning (a.k.a. Artificial Intelligence by the public).

Sir Edward William Elgar (English composer, 1857-1934), The Snow, Op. 26, No. 1

Text by Lady Caroline Alice Elgar (English author, 1848-1920)


O snow, which sinks so light,

Brown earth is hid from sight,

O soul, be thou as white,

As white as snow, as snow,

O snow, which falls so slow,

Dear earth quite warm below;

O heart,

O heart, so keep thy glow,

Beneath the snow, the snow.


O snow in thy soft grave

Sad flow'rs, sad flow'rs the winter brave;

O heart, so soothe and save,

so soothe, as does the snow.


The snow must melt, must go,

Fast, fast, fast, fast as water flow.


Not thus, my soul,

O sow

Thy gifts to fade like snow,

Not thus, not thus,

O sow not thus thy gifts to fade like snow.


O snow, thou'rt white no more,

Thy sparkling too, is o'er;

Be as bevore,

Was bright the snow.


Then as the snow all pure,

O heart be, but endure;

Through all the years full sure,

Not as the snow, not as the snow.
