RESEARCH:

My short bio can be found here and a description of some of my research can be found here.

I am always looking for students, and in particular PhD students, interested and willing to
participate in research projects in (or related to) the areas described here. On occasion,
I will even embark on projects that are completely new to me.

Interested students can consult the links given in this website to my papers, lecture
notes, and course information. If after that you are still interested to do research with
me, please, get in touch with me (through my email given above).

Beside mathematics and physics, I am very interested to interested in strongly
interdisciplinary projects.



==========================================================================

I have designed two new courses that I am very
excited to teach. Please, ask me about this material.

NUMBERS FROM ALL ANGLES:
I wrote the text for a course covering an introduction to several areas of number theory.
Here is the flyer for the full year course. The course is designed to emphasize connections
with other areas of mathematics such as analysis, algebra and complex analysis, as well
as to make some classical results accessible to a wider audience of non-specialists.
With that, I aim for a wholly new approach in the teaching of graduate courses in Number
Theory. The book "Numbers from All Angles" is based on this new approach and is a
thoroughly corrected, rewritten, and expanded version of the notes. It has been
published by Springer Nature. You can find the preface and contents here.


AN OVERVIEW OF CLASSICAL GRAPH THEORY:
I am writing a general 2-term graduate text highlighting main currents in the study
and applications of undirected graphs. Again, the emphasis is on establishing
connections with other areas of mathematics. Current chapter titles are:
Graphs in Surfaces; Graph Colorings; Spectral Methods: Basics; Spectral Methods:
Fiedler and Cheeger; Probabilistic Methods; Algebraic Methods. Connections with
topology, linear algebra, abstract algebra, and analysis are made explicit and explore.
There will be about 10 appendices, each exploring an exciting aspect, that would, however,
distract from the main narrative if delivered within the main text.

LAPLACIAN dYNAMICS IN DIRECTED NETWORKS:
In the summer of 2019, I participated in a summer school in Italy where I gave a mini-course
on the theory of directed graphs. 
This resulted in the design of the 1 or 2 trimester course
"Directed Networks". Here is the flyer for the course. Some of the material has been worked
into slides: see
part 1, part 2, part 3, and part 4.
This is esentially a slightly more
specialized course, following up on the previous book. I expect to finish the writing
in 2028 or before.

NOTE:
Nothing is perfect, and so I expect errors.
I appreciate if you report errors and welcome constructive criticism.
You can find my email at the top of this page.

Student Research Projects:

I have many research projects, Most are intended for 501 theses or PhD level projects.
If you are interested in doing a research project in:
Dynamical Systems, Social and Economic Networks, Coherent Motion of Flocks, Topology/Geometry,
Fractal Geometry, Discrete Mathematics, Mathematical Physics, Networks and Graph Theory,
or others, please talk to me.
