Welcome to my homepage. I am a fourth-year Mathematics graduate student at Rutgers University. My advisor is József Beck. By the usual mathematicians' convention, this site is perpetually under construction. For now, feel free to read any of the papers below.
We show that for any two linear homogeneous equations E0, E1, each with at least three variables and coefficients not all the same sign, any 2-coloring of Z+ admits monochromatic solutions of color 0 to E0 or monochromatic solutions of color 1 to E1. We define the 2-color off-diagonal Rado number RR(E0; E1) to be the smallest N such that [1,N] must admit such solutions. We determine a lower bound for RR(E0, E1) in certain cases when each Ei is of the form a1x1 + ... + anxn = z as well as find the exact value of RR(E0, E1) when each is of the form x1 + a2x2 + ... + anxn = z. We then present a Maple package that determines upper bounds for off-diagonal Rado numbers of a few particular types, and use it to quickly prove two previous results for diagonal Rado numbers.
There exists a minimum integer N such that any 2-coloring of {1, 2, ... , N} admits a monochromatic solution to x+y+kz = lw for k,l in Z+, where N depends on k and l. We determine N when l-k is in {0, 1, 2, 3, 4, 5}, and for all k, l for which (1/2)((l-k)2 -2)(l-k+1) ≤ k ≤ l - 4, as well as for arbitrary k when l = 2.

My research interests are in combinatorics. Too vague - currently, I am most interested in analytical methods in combinatorics, particularly in areas like graph & hypergraph theory, additive combinatorics, and some types of game theory. A few specific interests are within Ramsey Theory, especially Ramsey Theory on the integers. This means I have an interest in both Ramsey Theory (on the whole), and on the theory of arithmetic structure in the integers. I am still exploring other areas of combinatorics and related fields as specific interests. I would characterize my interest in mathematics, in general, as very broad. (There are many topics of mathematics that I find very compelling, although I only have a basic familiarity with them.) I enjoy the interdisciplinary nature of certain types of mathematics, and appreciate collaboration between mathematicians with diverse interests. Also, my Erdős number is 3 (check here).
