williams college Course Catalog (2015)
The academic courses are the link between faculty and students. We present a redesign of the Williams College 2015-2016 course catalog, which removed a bureaucratic and administrative ordering and replaced it by highlighting what really matters: the courses. These appear in three distinctive formats:
- a newspaper version, blending the classified ads of the old world and the twitter markings of the new.
- a printed book, where the courses are not broken down by departments, but displayed in alpha order.
- an online coursexplorer, providing a flexible, searchable style based on weightings, along with a visual calendar manager.
The cover of the printed book is shown above.
Cartography of tree space (2014)
In our enlightened world, the work of the mathematician and the visual artist are not only viewed as incompatible, but held in tension. The goal of this collaboration is to engage mathematics and the visual arts in a direct manner, with concrete outputs, that does not insult either field. In other words, new mathematical questions need to be formulated and new artworks need to be produced for the success of this venture. Our work is a true collaboration, with the mathematician (myself) involved in the drawings and the artist (Owen Schuh) involved in the mathematics.
The particular object of our study is a configuration space of phylogenetic trees. Each point in our space corresponds to a specific geometric, rooted tree with five leaves, where the internal edges of the tree are specified to be nonnegative numbers. From a global perspective, this tree space is made of 105 triangles, where three triangles glue along each edge. This results in 105 distinct edges, and 25 distinct vertices. This space of trees appears in numerous areas of mathematics, including algebraic topology, enumerative combinatorics, geometric group theory, and biological statistics.
The collaboration took place during an 18-month timeframe, from September 2013 until February 2015. Roughly, the first six months were spent in understanding the goals of the project and choosing a point of collaboration. The second six months were spent at coffee shops and studios, where we would meet and go through both mathematics and sketches. The final six months were focused on crafting extreme details and formulating a unifying vision for the project. Two painting of the triptych are shown above.

Major and Career infographic (2012)
It is the liberal arts approach to higher education that makes the American model of higher education simply extraordinary. And the world is taking notice. All eight of the Hong Kong public universities migrated from a three-year British model to a four-year international system, signaling a major shift in educational philosophy. The move abandons a specialized focus and embraces more time for students to gain exposure outside their major. The University of Delhi, a top-ranked institution in India, followed suit, also moving to a four-year undergraduate program that requires every student to take eleven foundation courses regardless of major.
In America, schools like Williams College have doubled-down in the liberal arts ethos, and it seems to be successful. This graphic, created by myself and two of my former students, showcases the trajectories of 15,600 Williams alum. The left side of the circle is broken into different categories of majors, and the right side into categories of careers, where each alum has an arc going from left to the right, from their choice of major to their resulting career.
There are two stories in this graphic. First, there is a strong correlation between biology and chemistry majors with the health and medical field; this is no surprise for such a specialized discipline, with pre-med requirements and MCAT exams. And second, each career receives a fair percentage of students from every major grouping. In other words, your career does not seem to be determined by your major – the liberal arts graduate is trained to adjust and conform in an evolving market.
mural to mathematics (2009)
The Williams College Mathematics and Statistics department is located on the second floor of the wonderful Bronfman Science Center. This second floor entrance occurs in a stairway, which has two bright red doors, with a large wall separating them. On this wall was a coat rack that had pegs to hold 25 coats. The goal was to transform this space into an entrance worthy of the department, to design and execute a site-specific piece of work. With ten students in my Mural course, we created this piece, with underpinnings dealing with:
- a Voronoi diagram motivated from biological patterns.
- two red tiles (hiding the light switch) that were Schlegel diagrams of the 3D associahedron polyhedron.
- a four-coloring of the tiling, broken into two tree structures, with blue and yellow themes.
The mural is shown above, with two bright red doors on either side.
sculpture studio (2007)
What would happen if you explained five unsolved mathematical problems to five pairs of students, and asked them to visualize the concepts at hand, no holds barred? This was the premise behind the Geometric Modeling course. The results were spectacular, with sculptures made out of metal, wood, plexiglass, and computer graphics. The above photographs show two of the works.
- The left piece deals with a metal skeletal framework of a 4D associahedron polytope, created by Eric Jonash and Sam Kapala. The vertices of this polytope correspond to all ways of triangulating the regular seven-gon, and the edges connect two such triangulations related by a flip. It was a long standing open problem (solved in 2012 by Lionel Pournin) which asks for the diameter of the associahedron for arbitrary dimensions.
- The right piece deals with the smallest flexible 3D polyhedron, made of plexiglass and piano hinges, created by Rohan Mehra and Norman Nicolson. Although the faces are rigid, the entire object flexes in a smooth, elegant manner, with a one-dimensional parameter of freedom. It is a stunning result of Sabitov that the volume of this (and any other) flexible 3D polyhedron remains constant during the deformation. It is an open problem whether the Dehn invariant alters during the flex.
My mathematical research deals with structures of arbitrary dimensions. To understand work of such complexity, I am committed to bring a clear understanding for lower dimensional examples (such as dimensions two, three, and four). Since all of this is presented on flat paper (or monitor) to the reader, an incredible compression of data occurs. Thus, color, line width, and transparency are used to convey more information. Photography struggles with similar issues, capturing high dimensional information onto a flat canvas.
